ThermoWood Rainscreen Cladding 26x68mm

The ThermoWood Rainscreen Cladding 26x68mm is a thermally modified timber board designed for use within ventilated rainscreen cladding systems. Engineered to deliver enhanced dimensional stability and durability, this profile is suitable for external wall applications where moisture control and long-term performance are critical.

Rainscreen cladding systems rely on a drained and ventilated cavity behind the cladding layer to manage rainwater and support controlled drying of the wall build-up. ThermoWood is produced through a chemical-free thermal modification process that reduces moisture uptake and movement, making it particularly well suited to rainscreen façades exposed to variable UK weather conditions.

This board forms part of our rainscreen cladding range and is intended for installation over a battened cavity with appropriate membranes and fixings. The 26x68mm section provides a slim, consistent profile that integrates cleanly into contemporary timber façade designs. Correct cavity depth, ventilation paths, and fixing methods are essential to ensure reliable long-term performance.

ThermoWood rainscreen cladding boards are supplied with a rich brown tone that will weather naturally to a silver-grey if left untreated. Where colour retention or extended maintenance cycles are required, suitable external coating systems may be applied. Proper specification and detailing will ensure predictable behaviour and a stable, low-maintenance timber façade.
