Ever since the 40's, we have observed and learned how to make a window or an exterior door that lasts over time. Chemical wood protection is for many a solution. Constructive wood protection is for us the optimal solution. Constructive wood protection means that the product is designed with regard to the external factors that affect the product over time. It may seem obvious but it is not something that everyone lives up to. Examples of constructive wood protection can be the design of profiles to prevent water from standing, to avoid capillary traps and to have a construction that is tight and does not allow moisture to penetrate and stand. For constructive wood protection, you can also add a choice of materials and a choice of color system. EKSTRANDS windows have the glass strip mounted on the inside and the glass is fully glued. We work according to the same principles on our exterior doors, top sealing between glass and wood is made with high-quality silicone instead of simple rubber strips etc. On our exterior doors, we use the same more environmentally friendly paint system as on our windows, a diffusion-open system that is durable over time. We use both surface materials that do not shrink or swell and twig-clean and / or heat-treated wood.
