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. With an impressive lambda value, PIR boards from Celotex and Mannok assure robust thermal performance and can be used in floors, roofs, and walls for comprehensive insulation.

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.

When to Choose Mineral Wool:

  • When excellent fire resistance is paramount.
  • For improved acoustic insulation alongside thermal properties.

 

Sheepwool

For the eco-conscious, 100% Sheepwool Insulation rolls, available in Comfort, Optimal, and Premium ranges, provide a sustainable choice, ensuring non-itch, breathable, and high-performing thermal solutions. It brings a natural option, handling humidity effectively by absorbing and releasing moisture without compromising R-values.

  • When moisture management is crucial.

 

Multifoil Insulation

Thinsulex TLX Silver Multifoil offers a reflective insulation solution, ensuring minimal thickness with high thermal efficiency. The multilayer foil reflects radiant heat, effectively reducing heat transfer and providing a cost- and space-efficient insulation strategy.

When to Choose Multifoil Insulation:

  • When space is highly constrained.
  • For enhanced reflection of radiant heat.

 

Rigid Thermoset Insulation

Kingspan Thermapitch TP10 provides a rigid thermoset insulation solution designed for a robust, long-term, and consistent thermal performance across a multitude of applications, including tiled or slated pitched warm roof spaces.

Selecting Your Ideal Between Rafter Insulation

In choosing between the myriad of options, consider:

  • Space: The availability and constraints of installation space.
  • Application: The specific area of use such as walls, floors, or roofs.
  • Sustainability: Environmental impact and sustainability credentials.
