Thermal Efficiency and Moisture Control

This wood fibre board is manufactured from sustainably harvested natural fibres, providing superior thermal regulation that maintains comfortable interior temperatures year-round. Its high vapour permeability enables effective moisture dissipation, minimising condensation build-up and supporting improved indoor air quality.

Durable and Strong

Lightweight in construction yet structurally rigid, this sheathing board is straightforward to handle and fit whilst delivering extended protection. The material's inherent strength reinforces wall and roof assemblies, withstanding harsh weather conditions, precipitation, wind exposure, and thermal stress. Particularly suited to roof sheathing, wall reinforcement, and external insulation systems.
