When people think about timber doors and windows, they usually think of oak. Oak has been used for years and still looks great on many homes. But there is another type of timber that has become much more popular recently, and that is Accoya.
A lot of homeowners are now choosing Accoya for external doors and windows because it lasts a long time, needs less maintenance, and handles British weather really well.
Accoya starts as a softwood, but it goes through a special treatment process that changes the structure of the timber. This helps stop it from soaking up moisture like normal wood does. That might not sound important, but it makes a huge difference once the timber is outside in rain, cold weather, and changing temperatures.
One of the biggest problems with ordinary timber is movement. During winter and wet weather, wood can swell up. In summer or dry weather, it can shrink. Over time this can cause doors to stick, windows to become harder to open, and paint to crack.
Accoya is much more stable than standard timber, so it moves far less throughout the year. That means doors and windows stay working properly for longer and usually need less maintenance.
Another reason people like Accoya is because it is very resistant to rot. External joinery has to deal with constant weather changes in the UK, especially with rain and damp conditions. Some timbers can struggle over time if they are not looked after properly, but Accoya is designed to last much longer outdoors.
It is also a great choice for painted doors and windows. Because the timber stays stable, the paint tends to last longer before it starts peeling or cracking. This helps keep external joinery looking fresh for longer and reduces how often repainting is needed.
Many modern homes now use coloured timber windows and doors, especially black, anthracite grey, and heritage colours. Accoya works really well for these types of finishes.
Another thing homeowners like is that Accoya is energy efficient. Timber is already a natural insulator, but Accoya performs especially well when combined with modern glazing. This can help reduce draughts and improve comfort inside the home.
There is also the environmental side. Accoya is made using sustainably sourced timber and is designed to have a very long lifespan. Because it lasts so long, it can be a more environmentally friendly option compared to materials that need replacing sooner.
That does not mean Accoya is always better than oak. Oak still has a beautiful traditional appearance that many people prefer, especially on period homes, cottages, and barn conversions. But for homeowners wanting a painted finish, lower maintenance, and excellent long term performance, Accoya has become one of the most popular choices in the UK.
When properly manufactured and installed, Accoya doors and windows can stay looking good and working properly for many years, even in harsh British weather.
