VENTILATED TIMBER CLADDING WITH PIR INSULATION
The ventilated ThermoWood® façade combines external insulation, a timber substructure and durable thermally modified cladding. The drained cavity protects the wall and supports airflow.
Verify substrate, height, wind, fire, openings and fixings for the project.
Prepared masonry or concrete wall supporting the complete façade system.
High-performance rigid insulation reducing heat transfer through the external wall.
Durable timber substructure creating the ventilated cavity and supporting the cladding.
Continuous drainage and airflow space behind the external timber finish.
Thermally modified timber finish providing stability and natural architectural character.
Keep the base-to-top cavity open for continuous airflow and drainage.
Use a suitable vapour-open breather membrane and correctly detailed openings.
Select exterior-grade battens and corrosion-resistant fixings for loads and coastal exposure.
Allow timber movement; coordinate openings, corners and closures.
Thermally modified exterior timber profile.
Substructure forming the ventilation and drainage cavity.
Corrosion-resistant exterior façade fixing.
Water-resistant and vapour-open protective layer.
Protects cavity openings while maintaining airflow.
High-performance rigid thermal insulation.
Untreated ThermoWood® naturally develops a silver-grey surface. Appearance varies with exposure, detailing and maintenance.
