Installing insulation

Wood and metal frame exterior walls can be cost effective, quick, and flexible for both residential and commercial construction. They create the opportunity for high-performance assemblies with continuous control layers on the outside, while providing additional space to accomodate for wiring and plumbing within the stud cavity.

Insulating stud cavities with stone wool can help builders and owners alike meet performance targets for energy efficiency, comfort, and safety.

Why do we need wood frame insulation?

Wood studs 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 wood frame wall insulation delivers excellent fire resilience and soundproofing capabilities, alongside its thermal resistance qualities.2

Wood stud house insulation is well suited for use in wood stud buildings with its quick and easy fitting and dimensional stability. It will adjust to the small movements of the construction and stay in place for a lifetime.

Benefits of ROCKWOOL products include:

  • Fire resilience
  • Sound absorption
  • Thermal resistance
  • Flexible application
  • Water repellent
The low carbon footprint of ROCKWOOL wood frame products is a perfect match with that of the wooden structure. The construction is easily dismantled at the end of its lifecycle, adding to the reduction of our environmental footprint.
