Insulation Calculator for B&Q Products
We'll adjust units, stud spacings, and insulation ratings based on your region.
Select the part of the building you want to insulate.
Enter the total area directly, or calculate it from room dimensions.
Choose the spacing between your wall studs, ceiling joists, or floor joists.
Choose the thermal resistance level for your insulation. Higher values mean better performance.
Our free insulation calculator is designed to work with B&Q insulation products available in the UK. Calculate material quantities in metric units and ensure compliance with UK building regulations.
Getting your insulation quantities right the first time saves money and multiple trips to the store. Our calculator takes the guesswork out of insulation planning by providing accurate estimates based on your specific project dimensions, stud spacing, and target R-value. Whether you are a DIY homeowner or a professional contractor, this tool streamlines the estimation process.
B&Q stocks Knauf, Rockwool, Celotex, and Kingspan insulation products including mineral wool rolls, rigid PIR boards, cavity wall insulation, and loft rolls for UK homes.
UK Part L Building Regulations require minimum U-values of 0.30 W/m2K for walls, 0.16 W/m2K for roofs, and 0.25 W/m2K for floors. Our calculator helps you meet these standards.
Measure your loft floor area in square metres, then use our calculator with the UK country selection. The recommended depth is 270mm of mineral wool to achieve the required thermal performance.
Stay informed with expert tips on insulation, energy efficiency, and home improvement.
Proper home insulation is one of the most impactful upgrades you can make for energy efficiency. In this comprehensive guide, we cover everything from choosing the right insulation type—fiberglass batts, blown-in cellulose, spray foam—to understanding R-values and local building codes.

R-value measures how well insulation resists heat flow. A higher R-value means better thermal performance and greater energy savings. But what R-value do you actually need? The answer depends on your climate zone and local building requirements.
