Accoya® modified wood has been selected as the wood of choice by The Dauphin Way United Methodist Church in Mobile, Alabama.
The revolutionary modified wood was used by Oakleigh Custom Woodworks to replace 14 window frames that had become damp and unstable due to the region’s challenging and extreme climate.
The new windows needed to provide the Church with long-term cost savings whilst using high-specification and aesthetically-pleasing materials that could withstand the damp and humid climate of Alabama. Accoya was specified as it reduces swelling and shrinkage by 75% or more, helping coatings last three to four times longer and therefore reducing maintenance costs.
Accoya wood, manufactured by Accsys Technologies, is one of the most advanced wood products on the market, using wood modification technology to deliver outstanding levels of performance, stability and durability. It is created by using a proprietary non-toxic process, called acetylation, on sustainably sourced woods. This results in an attractive wood which matches or exceeds the properties of tropical hardwood, which is perfect for a variety of uses from windows to doors to external cladding.
Anne Read, co-owner of Oakleigh said: “Accoya is a great wood, and fits perfectly for our environment. It is an ideal fit for climates where there is excessive rainfall or striking temperature ranges – one day it can be over 26 degrees and the next it is below freezing, but Accoya holds up perfectly.
“Accoya is able to withstand these extreme weather challenges and as a result is guaranteed against rot and decay for 50 years for exterior use – making it the ideal solution for the Church as a long term investment.”
Each of the Church’s six-metre high window frames contain 56 double panes of glass and replicate the original windows which date back to the 1960s. The frames were painstakingly assembled using pre-made parts, with each length being crafted from subcomponents before being finger-jointed into the window frame.
The custom made Accoya windows included insulated or low-E glass which promised a 30% reduction in the building’s five-figure annual energy costs, and high-quality paint.
Oakleigh used four pieces of Accoya wood to create strikingly beautiful wooden arches for the windows. The windows benefit from custom-lap joints, in which continuous vertical and horizontal muntins are notched at each intersection to create a lattice for stronger joints. Accoya performs as well as other wood materials during this process – but its durability and stability means the finished items remains in better condition for longer.
