Unilin Insulation’s Rafterloc Pitched Roof insulation is a high-performance PIR board designed for use between rafters in pitched roof constructions.

Variable width feature provides flexibility between rafter spacings, helping achieve a tight, secure fit between rafters.

This helps reduce gaps, cutting, and installation waste caused by uneven timber spacings, while improving overall installation efficiency.

When used in conjunction with a layer of Unilin XT/TL or XT/PR_UF below the rafter, the system delivers a robust and cost-effective solution for achieving excellent thermal performance and supports improved U-values in line with current building practice.

The design helps reduce thermal bridging through timber rafters and supports improved U-values with minimal intrusion into living space.

Why use Rafterloc?

Rafterloc is designed to improve the efficiency and accuracy of pitched roof insulation installation.

The variable width feature ensures a tight fit between rafters, even where timber spacings are inconsistent, helping to eliminate gaps and reduce heat loss.

This results in improved thermal performance, reduced installation time, and less material waste.

When combined with additional Unilin insulation layers, it provides a high-performance solution for achieving targeted U-values in both new build and retrofit projects.

Typical applications:
  • Pitched roof insulation between rafters
  • New build roof insulation systems
  • Energy upgrade and retrofit roof projects
  • Systems requiring improved U-value performance
