Functional architectural solutions with natural appeal

The natural beauty, functionality and environmental sustainability of wood are undoubtedly concepts we all cherish. At Thermory we process our timber naturally, using only heat and water vapor, to ensure it can last a long time outdoors. We have created a versatile range of profiles, including some with hidden fixings, as well as a variety of embossed patterns and finishing options and modular solutions to inspire architects and designers to find more ways to use wood in their architectural solutions.

We also provide BIM files, technical data, training, consultations both online and in our showroom, samples and inspiration from around the world – all to help you find just the right Thermory product for your project and make the most of our product data for designing and customer presentation.

BIM library

Building Information Modeling (BIM) files are digital tools that help architects and designers work with intelligent 3D models. The format has become increasingly common in building design and construction. Thermory’s technical BIM files include Revit, Archicad and material texture files.

Product specifications

Choose the most suitable wood species for your project according to the desired application, required durability rating and appearance. All Thermory cladding and decking boards have undergone intensive thermal modification to ensure durability in changing weather conditions. The wood’s durability rating indicates the rot resistance of the particular species (EN 350:2016), and the highest resistance rating for wood is Class 1 (25+ years). To make installation easier a wide range of fixings are available, some of which are concealed to create a clean, screw-free wood surface. Products with end-matching enable more efficient use of materials so nothing is wasted.

Wood maintenance

Thermally modified wood is easy to maintain and doesn’t necessarily require surface treatment. Like any other wood however, when used outdoors and exposed to UV radiation the surface of Thermory products will naturally turn gray over time. This process starts immediately after the products are installed and can take from a few months to several years depending on how much UV light they’re exposed to. The durability of the products is not affected by the graying process.
If you wish to preserve or alter the wood’s color tone, Thermory boards can be coated with a UV-resistant pigmented mineral oil.
