We will soon be manufacturing our sash Windows with the very impressive Accoya timber. Guaranteed not to warp, shrink, twist, or rot for 50 years..... Thats right 50 years! Also, by using Accoya we can now guarantee our Teknos paint finishes for 12 years, meaning that you no longer have to worry about re-painting every few years. There are many more benefits to using this fantastic timber, and over the next few weeks we will be updating our website with dedicated pages, containing all the information of how this timber works.
