Home insulation designed to cut heat loss and help prevent damp in lofts, attics and roof voids. Installers and DIYers get safer handling and year-round comfort with fewer cold spots. Is the Green Loft Thermal Insulation Roll the right choice for small renovation and retrofit projects?
⚡ At a Glance
- • Thermal Performance: R-Value 2.29 m²·K/W at 50mm thickness, 1.8 m² coverage per roll
- • Best for: Lofts, attics, wall cavities, sheds, garages and roof voids in renovations or new builds
- • Not ideal for: Situations needing higher R-values or thicker insulation layers for regulatory compliance
A 5-metre roll of non-itch polyester loft insulation with 50mm thickness and R-Value 2.29. Hydrophobic fibres resist moisture to reduce condensation and mould risk.
Lower heating loss - with R-Value 2.29 polyester insulation
The roll measures 5 metres by 370mm with 50mm thickness and a stated R-Value of 2.29 m²·K/W, which indicates resistance to heat flow through the material. Coverage is 1.8 m² per roll, allowing predictable thermal improvement when fitted across a given area.
Reduced heat transfer keeps rooms warmer in winter and helps limit unwanted summer heat, making homes more comfortable and energy-efficient. Predictable coverage simplifies planning for small-scale loft or cavity installations.
Reduced damp and mould risk - with hydrophobic polyester fibres
Hydrophobic fibres repel moisture rather than absorbing it, which lowers the chance of condensation building up inside cavities. The material is specifically described as resistant to mould and mildew where enclosed spaces are prone to damp.
Repelling moisture helps protect timber and interior finishes and reduces the need for repeated remedial work. The result is a drier loft or roof void that supports longer-term building health.
Safer, quicker installs - with non-itch, chemical-free polyester
Non-itch polyester construction means fibres do not cause skin irritation and no chemical treatments are used, allowing handling without gloves or masks as described. The roll is lightweight, flexible and designed to hold shape with a no-sag profile.
Installers can cut and fit roll sections easily, even in tight spots, speeding up DIY or trade work while avoiding the discomfort of fibreglass. Long-term shape retention reduces the risk of gaps forming after installation.
✨ The 4 Key Reasons for Green Loft Thermal Insulation Roll
