What to expect with uncoated Accoya

Accoya weathering

Accoya weathering

Wood is an organic material, and it changes over time as it reacts with the sun and the rain, developing new colours and textures: a process known as weathering.

Accoya, as a natural wood product, is no different

Like other wood species, uncoated Accoya wood will weather over time to an elegant slivery grey colour when left outside and exposed to the elements.

Unlike other woods however, weathering does not affect the durability, stability or performance of Accoya.

During the weathering transition process the surface colour of Accoya can appear patchy due to the different levels of sunlight and rain coming into contact with the wood, but over time it evens out to a beautiful silvery grey effect that lasts for decades to come.

Because Accoya has such great dimensional stability, coatings are not so stressed by shrinking and swelling forces that affect all other types of wood – meaning they last and look better for longer. For certain applications such as windows it is industry standard for frames to be coated to protect the other parts of the window fittings and mechanisms.

Pressure treated wood vs. modified wood – A beginners’ guide

21.04.2021

Choosing the right wood
When it comes to choosing which type of wood you need for a project, you might assume it to be quite straightforward… but making the best choice now could save a lot of time, hassle and money later.

So, what do you really know about the differences between pressure-treated wood and modified wood?  What do they mean, and what are the key benefits of one over another?

Wood is something that we all know a little bit about, and sometimes that’s enough. There’s hard wood, soft wood, MDF, and they all have typical uses… but we all also know that really there’s a bit more to it than that.

So, how much do we really know about the oldest building material of all, and – more importantly – how do we know what wood is actually best for a particular application?

 

Cost vs value
We all want the best value for our money, and sometimes that means shopping on a budget in search of value – but often at the expense of performance.

For this reason, most of us have probably heard the term ‘Pressure-treated Wood’ as a ‘cheap’ option, and perhaps ‘modified wood’ or ‘engineered wood’ as the high performance choice… but there is more to consider than the up-front cost and more to ‘cost’ than just money.

The word ‘Treated’ suggests that something has been added to the wood to improve its performance or durability… and if you think that, you would be right.

What is pressure-treated wood?

Pressure-treated wood is normally a soft wood that has been immersed in a liquid preservative within a pressure chamber. The high pressure forces the chemical into the fibre of the wood rather than just treating the surface.

Pressure-treated wood has long suffered from a somewhat bad reputation over the years, due to the chemicals used to treat the wood. If the words ‘chromated copper arsenate’ (CCA) don’t mean anything to you, don’t worry, it doesn’t exactly roll off the tongue.

The problem is primarily to do with the last word ‘arsenate’ – derived from arsenic, probably the most famous poison EVER. ‘Leaching’ of this chemical, where it comes out from the wood, posed serious health risks both to the people handling it and the wider ecological environment with a nasty effect on animals and plants.

But there’s good news: governments around the world, having woken up to the serious dangers posed by CCA pressure-treated wood, have spent the last couple of decades largely banning its production and particularly its use in residential situations.

So, what has it been replaced with you ask?

The most widely used alternative to CCA is something called ‘Alkaline Copper Quaternary’ or ‘ACQ’. As you might expect, ACQ pressure-treated wood is safer than CCA for both humans and the environment, but sadly there is quite a trade-off when it comes to performance.

 

What performance can you expect from Pressure-treated wood?

Like all materials, it depends on where and what you do with them, and pressure-treated wood is no exception. The general consensus seems to be that it should last anywhere from 9-30 years (of course also depending on the level and frequency of maintenance you’re prepared to commit to).

Pressure-treated wood used for decking and exposed to freeze-thaw and wet-dry cycles often last less than 10 years even without proper care and maintenance, however, the same wood out of the elements and carefully looked after has the potential to go the full 30+ years.

Regardless of the situation and care though, you definitely won’t be offered any kind of warranty on pressure-treated wood.

What causes pressure-treated wood to rot?

The decay or rot of pressure-treated wood is sadly an inevitability due in part to the way that the wood is treated. The chemicals added in the pressurised treatment vessel are only able to penetrate so far into the wood, meaning the core of the wood is still technically untreated. This is fine until the construction process starts and you need to cut planks to the correct length. When you cut through pressure-treated wood, you leave exposed ends that are significantly more susceptible to rot.

However, the biggest issue when it comes to decay in pressure-treated wood is a simple one, and the same one that affects completely ‘raw’ wood: moisture.

Although the pressure treatment delays the onset of fungal infestation, it is water that really causes the biggest issues. You only need to put an off-cut of pressure-treated wood in a bowl of water to see it being absorbed in just a few minutes. This causes the wood to swell, and then to shrink when it dies out, which in turn can cause the wood to warp, cup, split or crack – and potentially break the structure of your finished product if the gaps between pieces of wood become large enough. All these cracks and splits allow water to penetrate deeper into the wood, accelerating the effect by preventing the wood from completely drying out, and ultimately creating the ideal conditions for decay.

 

Pressure-treated wood – should you go with it?

Sometimes your budget must govern your decision-making, and for people looking at a low-cost option without much care or need for assured performance, then pressure-treated wood can be a good choice.

If you only need your structure to last for a relatively short time and you’re happy to commit to regular, frequent, and careful maintenance, then pressure-treated wood certainly has appeal.

But, if you’re creating something you really want to last and enjoy for decades to come, then you might want to think about some other high-performance solutions for your deck or other garden and outdoor uses.

 

What is the best alternative to pressure-treated wood?

When you’re going to the effort and expense of creating a deck or cladding a building, it’s important to know that it will last – you are creating it, it is yours, and you want to own and enjoy it for years (or decades!) to come.

Naturally, you also definitely don’t want to be in the position of having to pay for the materials and labour again in just a few years.

What is modified wood?

According to TRADA (The Timber Research and Development Association), ‘wood modification involves the action of a chemical, biological or physical agent upon the material, resulting in a property enhancement effective for the service life of the modified wood’.

It’s a bit of a mouthful but essentially means that the properties of the wood are actually changed by the modification process – enhancing performance by changing the wood itself rather than just soaking or infusing it with other chemicals.

To avoid making this article as impenetrable as modified wood, we’re just going to focus on chemically modified wood, partly because it’s the most well-known, but mainly because it really shows the highest benefits and performance, putting it at the top end of modified woods you can buy.

What’s the science behind chemically modified wood?

Acetylation’ is really the most established, proven and effective form of chemical wood modification. This is where the wood is subjected to an organic reaction with acetic anhydride – essentially vinegar without the water. If you remember that one friend at school who used to soak their conkers in vinegar, you may have an idea of what’s coming…

The purpose of the reaction is to address a part of the cellular structure of wood called ‘free hydroxyls’. These free hydroxyl groups are what water binds to: they allow the absorption and release of water in and out of the wood, causing all the swelling and shrinking, cupping and cracking, damage and decay. The acetylation process converts these free hydroxyls into ‘acetyl groups’ which water can’t bind to – significantly reducing the ability of the wood to absorb and retain water.

All wood actually has naturally-occurring levels of acetyl groups, typically higher in hardwoods and lower in softwoods, which is one of the factors in how durable different species of wood are.

So, by boosting the acetyl levels of the wood to prevent water absorption, acetylation addresses the root cause of many of wood’s potential problems, and offers several key performance benefits including:

  • dimensional stability, so your windows and doors won’t jam or get stuck, coatings will last longer, and there’s much less chance of cracks, splintering and damage from expansion and shrinking,
  • incredible durability, with very high resistance to rotting, decay and even insect or termite damage

With all these benefits you might be concerned that the chemicals used in the process could be harmful or dangerous. While acetic anhydride itself is not very pleasant given it’s very low pH level, it’s only used to modify the wood – the actual finished product is completely non-toxic and is certified safe for humans, animals and the environment.

What performance can you expect from acetylated wood?

Acetylated wood is unrivalled in terms of its durability and stability, especially compared to untreated or pressure-treated wood. Accoya® acetylated wood leads the modified wood industry, and it’s the only wood in the world to offer a 50-year warranty: half a century of guaranteed peace of mind, and industry experts have even stated an expected service life of 70+ years.  It even has a 25-year warranty for use in or underwater, proving its performance even in the toughest conditions.

As with all materials it will still benefit from a bit of maintenance and cleaning, but requirements are substantially reduced, and the impacts of irregular work are considerably less severe.

With these performance properties, it’s no wonder that more and more people, and expert joiners and manufacturers, are selecting Accoya as their wood of choice, for windows, doors, decking, cladding, fencing and other exterior wood applications.

In summary – choose what’s right for your needs

There’s no hard and fast rule in selecting the best type of wood for your needs. As always you will need to balance cost with performance, monetary value with time, effort, ongoing costs and peace of mind.

So, before you start, remember that your choice now is one you’re making for years ahead.

Selecting pressure-treated wood could well be cheaper in the moment, but also a false economy, especially if you’re going to have to replace your construction or project a couple (or even five!) times compared to modified wood.

With enough uncertainty in our lives already, you can depend on the fact that Accoya is most durable and stable wood on the market, and if you want your project to go the distance then you need to build with the best.

Transforming your home into a staycation retreat

With holidays abroad still looking uncertain, thousands of Brits may be spending even more time at home this summer. Even with the ban on international travel set to potentially lift in May, it’s not a sure thing, and up to 90% of UK summer holiday options are already sold out! Here’s some ideas and inspiration for transforming your home into a staycation retreat.

22.03.2021

So, with no beach stays for the foreseeable future, what can you do to make your own outdoor space a treat to spend time in?  It may be easier than you think to create your very own attractive al fresco area to while away the summer hours, whether basking in the sun or enjoying the long evenings. With spring now (just about) upon us and good weather hopefully on the horizon, let’s take a look at four outdoor trends we expect to see this year that will help make houses and homes into luxury staycation retreats.

Invest in the outdoors

As the covers come off this spring, we expect homeowners to once again prioritise their outdoor spaces when it comes to home improvements. Summer lockdown in 2020 saw a DIY boom with online sales of garden and home improvement materials tripling, and this year looks set to be no different.

Whether it’s building a new set of planters or digging new flowerbeds, we Brits love to garden – in fact, 42% of us regularly partake in gardening – that’s a huge 27 million people nationwide. Working in the fresh air of the garden is well known to reduce stress and boost your mental and physical wellbeing, giving you a renewed sense of purpose and achievement (which we can all agree is much needed this year).

We all now have a golden opportunity to spend more valuable time in the garden, and for many, that will mean rolling up the sleeves and getting stuck into jobs like recoating our deck and repainting the garden furniture.

The natural charm of timber decking

The natural charm of timber decking

Timber remains the classic choice for outdoor decking, despite advancements in alternative materials, and it can certainly enhance the look of any garden. Choosing the right timber decking to complement your outside space is critical though, and there are some considerations to bear in mind including a budget, maintenance and style.

Timber is warm and beautiful and can give your garden a natural charm that you just can’t achieve with plastic. It is easily cut and shaped to work around your existing garden features and can be stained, treated or coloured with a vast range of coatings and textures to suit your look. Installation costs tend to be lower than other materials, and depending on your budget, there are plenty of different options, such as softwoods, hardwoods and modified woods such as Accoya®. When it comes to maintenance, more durable species or modified wood are good options with less regular upkeep required to keep your deck looking pristine all year round. Finally, don’t forget that sourcing environmentally friendly timber decking should always be on your radar, so look for the FSC® certification if in doubt.

Escape to the garden office

Escape to the garden office

There’s no doubt that COVID-19 has fundamentally changed the way we work. Although permanent home working is likely to be gradually replaced by a flexible hybrid office/home model as restrictions ease, there will still be thousands of us tapping away on laptops at home this year.  So, it’s no surprise that we’re seeing demand for garden offices soar as workers seek a quiet space outside away from the noise of the house.

Garden offices tend to be entirely separate from the house, fully insulated with heating and built for all weather conditions. Depending on space, they can range in size from a single person room to a fully kitted out office with a built-in kitchen and bathroom. Cheaper than a house extension, garden offices also come with significantly less environmental impact, particularly if built from or clad in sustainable timber.

Get outdoor cooking

Get outdoor cooking

A year of stay-at-home restrictions has elevated the need to fully maximise any outdoor space you may have, improving both functionality and aesthetics. According to Google Trends, searches for ‘outdoor kitchen ideas’ have surged by 60% in the UK since the start of the year, and they’re a great way to extend your available interior space for alfresco socialising with friends and family. If you’re missing that feeling of cooking outside on a barbecue in the early evening sunshine on holiday, this might be one for you.

Outdoor kitchens can be anything from a simple built-in barbecue to a full kitchen with a sink, preparation space and even a fridge. They can be built as a DIY job or made fully bespoke, but when buying make sure you consider durability just as you would with any outdoor furniture which may come under attack from the British weather.

Instead of more vulnerable materials like scaffolding wood, try a kitchen built with Accoya wood or Tricoya MDF board which have both been preserved through a unique acetylation process and will last far longer in wet (and dry) conditions – perfect for an outdoor kitchen that will last for many more summers to come!

10 Modern Wood Cladding Ideas

Options to set your home cladding ideas apart from the rest.

22.10.2020

Think of it as a good-looking coat.

Think of it as a good-looking coat.

The primary purpose of your home’s exterior cladding is to keep the weather out and protect your home from wind, rain, sleet and snow, heat and cold. But protection should still be attractive; your cladding can still look good whilst its benefits are working hard.

Performance criteria

Cladding performance is key. No one wants to wear a raincoat that leaks and your house is no different. Look for cladding with these six qualities:

  1. Beautiful – almost goes without saying
  2. Durable – it should last for decades
  3. Easy to maintain – no one wants to spend their time repainting and staining
  4. Resistant – able to stand up to rot, decay, and insect damage
  5. Dimensionally stable –  won’t warp or twist
  6. Warranty – that will protect you for decades

It’s not easy to find a product that meets all these criteria, but one great option is Accoya. Accoya cladding provides sleek, modern protection.

Accoya is one of the hottest wood cladding products on the market. Made using natural wood, Accoya is FSC® certified, made from responsibly harvested wood. Accoya is also non-toxic and contains no harmful chemicals, which leaves your home feeling and looking good.

10 Modern Exterior Wood Cladding Ideas Using Accoya

One of the beautiful things about modern architecture is that you don’t have to follow any rules.

1. Mix your cladding materials

Accoya cladding blends beautifully with other modern materials like concrete, stone and metal. And, because Accoya does not warp, cup or twist, your edges will always remain flat, smooth and true.

2. Go for the natural look, which has a definite modern vibe

Accoya can be left to weather naturally, leaving you with a lovely silver finish.

3. Or, use bold colors

Accoya readily accepts coatings like paint and stain. You can choose light or dark, white or black, and everything in between to coat your cladding.

4. Go exotic with Shou Sugi Ban

Shou Sugi Ban is a popular trend in wood cladding right now, particularly for modern home designs. This traditional Japanese technique of charring wood makes it more durable and gives the cladding a unique black color and burned texture for a long-lasting finish.

5. Vary the siding orientation

You can install your cladding vertically, horizontally, and even in patterns – all on the same home. And, because it is natural wood, Accoya is easy to work with.

6. Mix siding styles

The exciting part is that there are no rules. You can combine traditional narrow horizontal lap cladding mixed with wider vertical boards. Accoya comes in a variety of board widths, and it’s dimensionally stable, so joints stay smooth.

7. Mix textures

Most people underestimate the impact that texture can have on a home’s cladding. Mix rustic, natural wood with charred boards, smooth metal panels or stucco for a signature, modern vibe.

8. Vary dimension

Another technique is to create shadows by alternating board thicknesses. You can even put some boards flat and others on edge to create interesting shadows.

9. Mix things up at the ends

This technique, used instead of corner boards, leaves a decidedly modern feel.

10. Sharpen your corners

Accoya can be fabricated to create knife edges that will perform well and stay sharp over time.

The Sky’s the Limit

The beautiful thing is that there are no rules for modern home design. Accoya gives you the flexibility to do almost anything you want with your home’s exterior. You can be creative, but then you can sit back and relax, knowing that your home will be protected for decades while still looking good.

Een duurzame buitenkeuken voor het perfecte vakantiegevoel thuis

The sustainable outdoor kitchen

A sustainable outdoor kitchen for the perfect holiday feeling at home

A sustainable outdoor kitchen for the perfect holiday feeling at home

The outdoor kitchen has been on the rise for years. Indeed in some circles, it is almost common to have one. Though why would an outdoor kitchen suit you?

The first reason is a simple one. Cooking indoors in the summer isn’t always pleasant when we have high temperatures. The second reason; it is much more fun to eat outside than inside. In the United Kingdom, this isn’t always possible due to our changing weather throughout the year but when you get the chance, you usually want to make the most of it. 

Practical and easy

Practical and easy

Nowadays, there is a choice of outdoor kitchens, so you can choose between a modern or classic style. Most outdoor kitchens consist of a grill, sink, preparation counter, sometimes a pizza oven and for those who want even more luxury, a bar and refrigerator. If you are interested in DIY, you can make it yourself, otherwise, there are enough specialists in this field to make an outdoor kitchen that is tailor-made for you. 

 

Materials

Materials

The materials of your outdoor kitchen must be able to survive well in all weather conditions. Scaffolding wood is a commonly used option but unfortunately not very durable due to its vulnerability to moisture. A more suitable material is Accoya wood or Medite Tricoya Extreme MDF board. This wood has been preserved through an environmentally friendly acetylation process so that it hardly shrinks or swells and has an outdoor warranty of 50 years against rot. This means that not only can you enjoy an environmentally friendly choice but your outdoor kitchen can be enjoyed by future generations. If you choose a countertop, then limestone is recommended for this. Granite is also a popular option (but more expensive). If you want to create a Mediterranean atmosphere, you can also opt for Portuguese concrete tiles. 

A healthier choice

A healthier choice

You might almost forget but cooking outside is healthier for us. If you cook indoors, the house can fill with food odours and warm fumes. Of course you won’t be bothered by that outside. In good weather, you don’t have to go indoors to cook a meal, while everybody else enjoys the outdoors. You can prepare and cook a meal on your outdoor kitchen alongside good company. It is also the belief of many that cooking and eating in the garden is just a bit more fun than indoors. With an outdoor kitchen, you also cook healthier because the ingredients are grilled directly above the heat source, without adding extra fat or oil. 

So, get the holiday feeling in your garden with an outdoor kitchen and surprise friends and family with the best dishes!

What is Accoya?

We are regularly asked “what is Accoya?”

Is it a bookshelf from IKEA, is it a Japanese dish, is it a tree?

Often contractors or architects might not be totally familiar with this high performance wood, but have heard the name and want to know more about it. We hope to be able to answer that question in this blog.

Accoya is wood.

Right, ok.

So why have you never heard of the Accoya tree?

Well that’s because they don’t exist. Accoya starts life as a fast-growing pine tree (Pinus radiata) grown in managed forests. The pine tree is harvested once it reaches maturity at around the 30 year mark. It’s at this point its journey isn’t the same as other timber. We introduce the raw timber to a modification process as a plank or beam, the so-called acetylation process using acetic acid. Read more about acetylated wood here.  This process creates extremely dimensionally stable and durable wood.

Accoya® is the brand name of this modified wood.

Accoya wood is highly rot-resistant and very stable across varying climates. Containing no toxic substances as the process simply increases the levels of already present elements within the molecular structure of the wood.

Every piece of Accoya has been modified through to its core, providing the same performance and protection no matter how the wood is cut, planed, drilled, shaped, or more…

This makes Accoya ideal for many applications including window frames, doors, façades, cladding, decking, all without the use of preservatives. Accoya wood is Class 1 durable and surpasses even the most durable old growth tropical hardwoods such as teak.

How is it produced?

The production of Accoya is based on the process of wood acetylation. Scientists have proven that this modification process is an incredibly effective method to improve the technical properties of wood.

Wood acetylation works by changing the cell structure of the wood whereby the cell walls are “blocked” for moisture absorption. This modification reduces the wood’s ability to absorb water in the cell walls by about 80%, greatly improving dimensional stability, resulting in Accoya requiring less maintenance.

The change in cell walls means that insects and fungi do not recognise Accoya wood as a food source and therefore do not attack. Perfect for those parts of the world with termites or other wood eating critters.

What is so special about Accoya?

Durability
Finish

Accoya wood is Class 1 durable even in very challenging use environments. The wood is modified right through to the core. Each batch of Accoya is checked for quality by taking 19 samples in Accsys’  laboratories.

Accoya wood is Cradle to Cradle Gold CertifiedTM. This has been awarded to Accoya because it is fully circular. The process adds nothing to the wood that is not naturally present. An incredible sustainability story is shown in the life of Accoya wood. Supported by a 50 year above ground and 25 year in-ground warranty, effectively giving forests time to regrow across the total life cycle of Accoya, where other timbers have a shorter use life vs time taken to grow into logging maturity.

Wooden windows constructed with long-life Accoya

All common paint systems can be used to finish Accoya wood. Testing has been carried out across many different oil and water-based paint systems. Due to Accoya’s exceptional dimensional stability, barely shrinking or swelling, coatings will last longer. They don’t have to work as hard to move with the wood so will sit quite happily with far less maintenance, retouching, refinishing etc. This considerably reduces the number of paint strokes during the life of the window, door, cladding or whatever it may be.

Accoya can therefore be used in any desired project. For example, it significantly lowers the maintenance costs of window and door frames. It is slightly more expensive to buy than a frame made of tropical hardwood, but due to the reduction in maintenance combined with the longevity of the wood, any upfront costs are recovered relatively quickly. Plus, sticking or jamming doors and windows are a thing of the past with Accoya.

Many applications are possible due to the benefits of Accoya wood. The most popular applications are:

Façade cladding

Windows, doors and shutters

Decking boards and walkways

Garden furniture and play equipment

This makes Accoya ideal for many applications including window frames, doors, façades, cladding, decking, all without the use of preservatives. Accoya wood is Class 1 durable and surpasses even the most durable old growth tropical hardwoods such as teak.

We should be choosing the right materials for people as well as for aesthetic.

As per a Japanese study, plastic, metal and glass is impersonal in the workplace and has shown to increase blood pressure and stress levels. Whereas environments rich in natural materials, especially wood, can decrease blood pressure and stress levels.

 

Less stress, lower blood pressure, healthier immune system. These all add up to healthier and happier employees. This leads to better productivity and ultimately benefits the company, and the economy. Everyone’s a winner.

You may have heard of VOC's before.

You may have heard of VOC’s before.

Volatile Organic Compounds. These are chemicals released through the burning of fossil fuels, processing with synthetic materials, and can be present in every day consumer products. These are a socially acceptable poison on human health. Socially acceptable as for many years they were a by-product that may have been misunderstood, or in the balance of cost vs reward deemed worth the health risk. But today, with increasing concern around personal and planetary health, these are poisons that we don’t need to accept. And the easiest way to start reducing them in our day to day is to start without them, rather than starting to remove them.

Why?

Because you already know that anything less is potentially harmful to your health.

So why then do we accept the status quo and not challenge?

Given the opportunity to feel better, have less sick days, potentially help to avoid life threatening conditions. The majority of us should jump at the chance, but we need to transition away from should into will.

If almost your entire day is spent inside. It is our responsibility to ensure that we have a healthy working environment.

And wood is very much an answer.

Switching to wood for construction doesn’t mean that we will suddenly not have to worry about carbon emissions and defeating climate change. But it does offer one strand of possibilities in a much larger environmental piece. Making many smaller changes will build up into widespread change. From the perspective of personal responsibility, is it not your duty to preserve the planet for future generations? We won’t achieve that through continuing with the same high carbon, low re-use practices that we are accustomed to.

Proactive vs. reactive

Did you know that NASA published a list of air filtering plants that remove chemicals like formaldehyde, benzene and ammonia from the air? Naturally improving the air quality around you.

This is great. It’s great that a research organisation has put in the time and funding to compile a list of natural reactive treatments for an unhealthy environment.

But wait a second…

Why are these chemicals in your home in the first place?

Draw a timeline of your life. Hopefully not… But at some point you may become ill as a result of the environment you work and live in. Now would you rather treat that illness with medication? Or would you rather prevent that illness from ever having the opportunity to affect you.

This is essentially the question we must ask ourselves in modern environments.

Don’t look for a cure, look for prevention.

The BRE Biophilic Office is a great example of this.

Taking a human-centred approach to the spaces we sit in. Following research into using nature to inform the building choices and decisions best suited for a healthy environment. Leading to quantifiable improvements in productivity, wellness and a reduction in days absent due to illness.

We have proof. We have examples and we have common sense.

Now we must act, for the sake of our future health.
