Why do we need timber frame insulation?

Timber frames filled with insulation generally offer better thermal performance than masonry walls of the same total thickness.1 However, their reduced mass and wood properties mean they need the right material to provide strong fire protection and acoustic performance. ROCKWOOL timber frame wall insulation delivers excellent fire resilience and soundproofing capabilities, alongside its thermal resistance qualities.2

Timber frame house insulation is well suited for use in timber frame buildings with its quick and easy fitting and dimensional stability.

Benefits of ROCKWOOL products include:

  • Fire resilience
  • Sound absorption
  • Thermal resistance
  • Flexible application
  • Water repellent

Calculator and savings

The amount of insulation required will depend on the size and dimensions of the timber frame construction. With thermal requirements mostly determining the insulation thickness required.
