Fitting and handling
Allow the boards to acclimatise on site for at least 48 hours before installation, stacking them flat with spacers to allow air circulation on all faces. Fix through the tongue using stainless steel or A4-grade screws to allow for any residual movement and to keep fixings concealed within the profile. Although thermowood has good natural resistance to moisture, applying a UV-protective oil or finish is recommended to retain the warm brown colour and prevent premature surface greying.
FAQ
What is the difference between Thermowood and pressure-treated timber for cladding?
Thermowood is modified by heat and steam rather than chemical preservatives. The process reduces the timber's moisture content and alters the cell structure, improving dimensional stability and resistance to decay without introducing chemicals. This makes it a common choice for projects where chemical treatment is not preferred.
Will Ayous Thermowood cladding grey off over time?
Yes, like most timber cladding, it will gradually silver-grey if left unfinished. Applying a good quality exterior oil or pigmented finish will slow this process significantly and retain the original warm tone. Many homeowners choose to let it grey naturally for a contemporary look.
Is a PTGV profile suitable for horizontal and vertical installation?
The PTGV profile is commonly installed horizontally, with the groove facing down to shed water away from the board joint. Vertical installation is possible but requires careful attention to end-grain sealing and drainage detailing at the base to avoid moisture ingress.
