EARTHWOOL LOFT ROLL 44 - 200mm (8.1m2) Combi Cut Glass Mineral Wool
Who this product is for
Earthwool Loft Roll 44 suits homeowners and builders working on loft insulation projects where depth is not a constraint. It is ideal if you are upgrading an existing cold loft or installing insulation in a new build loft space. The combi-cut format makes it particularly suitable for standard joist configurations, saving time on site preparation and cutting.
- Trade installers and serious DIY customers
- Loft spaces with unrestricted insulation depth
- Standard joist spacing installations
Product format and coverage
This product is supplied as a combi-cut loft roll, meaning the insulation is pre-cut to fit between joists whilst maintaining full width across the roll. The 200mm thickness provides substantial thermal resistance for cold loft applications. Each roll covers 8.1 square metres, so calculate your total loft area and divide by 8.1 to determine how many rolls you need. The combi-cut format eliminates the need for on-site trimming to width, speeding up installation.
- Thickness: 200mm
- Coverage per roll: 8.1 square metres
- Format: Combi-cut (pre-cut to fit between joists)
- Long length rolls for efficient installation
Before you install
Check that your loft joists are in good condition and that the loft space is adequately ventilated. Measure your loft area carefully to confirm the number of rolls required. Ensure you have safe access to the loft and appropriate working platforms. Verify that your joist spacing matches standard dimensions, as the combi-cut format is designed for typical UK joist centres. If your joists are non-standard spacing, you may need to consider alternative formats or plan for additional cutting.
