ThermoWall 040 / 045

Wood-fibre external wall insulation boards for timber-frame and masonry substrates

ThermoWall 040 / 045

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.

Composition & Manufacture

  • Manufactured entirely from renewable resources
  • Manufactured entirely from by-products
  • No chemical additives
  • No toxins or toxic emissions during manufacture
  • CO2 zero-rated
  • Timber fuelled embodied energy
  • Actively recycled (i.e not theoretical)

Installation & Disposal

  • No known health risks for workforce or installers
  • Easily cut to shape and worked
  • No VOC emissions
  • Durable / Low maintenance
  • Reusable / Recyclable
  • Compostable

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
  • Free from toxins and allergens
  • Dimensionally stable (low thermal movement)
  • Helps regulate indoor climate
  • Low toxic fumes if burn

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.
