The Green Loft Insulation Roll is an ideal solution for homeowners and DIY enthusiasts looking to improve thermal efficiency in lofts, attics, and garages without the hassle of skin irritation. This high-performance, non-itch material effectively reduces heat loss to help lower energy costs, though users should note that the 50mm thickness may require double-layering if building regulations mandate higher R-value standards for your specific project.

No, the Green Loft Insulation is made from non-itch fibres specifically designed to be handled comfortably without protective equipment.
Yes, its flexible and lightweight nature makes it suitable for use in wall cavities, garages, and sheds.
Each 5-metre roll provides 2.85 square metres of coverage.
The material features hydrophobic properties which help it resist moisture and prevent mould growth.
Yes, you can stack layers if you need to increase the thermal resistance (R-value) for your specific project needs.
The product is supplied compressed; ensure you gently fluff the fibres by hand to allow air to enter and help the material reach its full 50mm thickness.
If the joist spacing varies, trim the insulation slightly wider than the gap to create a friction fit that prevents air bypass.
Installation is straightforward due to the material's flexible nature. Simply measure the distance between your joists and use a sharp utility knife or heavy-duty scissors to cut the roll to size. Because the roll comes compressed, allow the material to sit for a few minutes after unrolling; you can manually fluff the fibres to ensure they reach their full 50mm height. Regarding compatibility, the 570mm width is designed to fit standard joist centers commonly found in UK and European housing construction. For care, keep the insulation dry during storage and installation. While the material is hydrophobic, it is best practice to address any pre-existing roof leaks before installing the rolls to maintain the integrity of your insulation system.
