ThermoWall 040 and 045 boards are rigid insulation boards. They are manufactured from the by-products of sawmills in southern Germany. The softwood chippings are pulped and soaked in water, then mechanically pressed into boards, dried, and cut to shape. Boards thicker than 20mm are made up of 20mm thick laminations.

Performance

Excellent thermal performance in Winter
Excellent thermal performance in Summer
High compressive strength
Vapour permeable
Hygroscopic (absorbs & releases moisture)
Vermin and fungus resistant
Electrically neutral
Non-radioactive

Applications

• External walls (masonry & timber-frame)

Tongue and grooved ThermoWall boards can be applied directly onto timber frame without the requirement of a sheathing layer. ThermoWall boards are usually sold together with a mineral-based render system.
