RF Slight is a bespoke joinery manufacturer based in Tranent, East Lothian, proudly serving the Edinburgh and Midlothian areas. We specialise in crafting a wide range of custom timber products, including windows and doors, featuring designs such as Bi-Fold, Folding, Sliding, Fold and Slide, Lift and Slide, and traditional Sash and Case. We also create conservatories, staircases, and premium garden rooms/offices, all at highly competitive prices. Additionally, we offer wood flooring, timber decking, and stairparts.

At RF Slight, quality is at the core of everything we do. Our windows and doors are fitted with Planitherm glass units to ensure exceptional energy efficiency, featuring extremely low U-values that help retain warmth in your home while maximising natural daylight.

We use Accoya wood—a high-performance, sustainable timber that offers unparalleled durability and resistance. Accoya requires minimal maintenance, providing easy and hassle-free care that saves time and money in the long term. With a 50-year warranty above ground and a 25-year warranty below ground and in freshwater, Accoya wood is built to last for decades.

Our eco-friendly approach, combined with the use of Planitherm glass, ensures that our products not only enhance your living space but also contribute positively to the environment.
