Navigating through the vast world of insulation can be complex, especially when it comes to optimising between rafter insulation for your project. At Insulation4Less, we bring forward a diverse array of products tailored to meet varied insulation needs.

PIR Insulation Boards

In the realm of PIR (Polyisocyanurate) Insulation Boards, the Celotex GA4000 series, including GA4050, GA4070, GA4090, and more, is highly recognized for its multi-purpose applications, offering thickness variations to cater to different thermal resistance needs.

When to Choose PIR Insulation Boards:

  • When You require high thermal performance with minimal thickness.
  • For refurbishment projects where space may be limited.

 

Mineral Wool

Mineral wool like the Rockwool RWA45 and Knauf Loft Roll 44 Combi-Cut comes in varied thickness and sizes, boasting excellent thermal and acoustic insulation properties. The Rockwool Flexi-Slab and RW3, and Knauf Acoustic Roll further showcase the versatility of mineral wool in providing a snug fit between rafters, ensuring no gaps and thus, optimal performance.
