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.

ROCKWOOL Comfortbatt® semi-rigid thermal batt insulation for exterior wall cavity wood and steel framing

Comfortbatt® is a stone wool insulation thermal batt for use in both new residential construction and renovations. A unique, flexible edge helps maintain R-values.

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

Installation

Installing wood stud wall insulation during construction or as prefabricated elements is the common method. It can sometimes also be retrofitted to existing properties.

Key tips:

  • Choose insulation type – Pick an insulation product suited to the size and dimensions of the frame.
  • Build airtight – Apply an airtight vapour barrier on the inside of the construction to avoid thermal performance loss.
  • Weatherproof – Avoid insulation and the timber frame getting wet where possible, as this can lead to leaks before the insulation is installed.
