Helping Windsor homes stay warmer, cooler, and more energy-efficient
At The Loft Access Company, we provide professional loft insulation in Windsor, Eton, Old Windsor and the surrounding Berkshire area. With high-quality thermal fibre insulation and expert installation, we help homeowners lower energy bills, stay comfortable year-round, and meet UK Building Regulations.
Balancing Loft Insulation Depth and Headroom
Many Windsor homeowners — especially those in older terraced houses — worry about losing loft headroom when upgrading insulation. Extra insulation does raise floor height slightly, but the long-term energy savings far outweigh this small change.
Older homes often have around 100 mm of insulation. Today’s recommendation is up to 270 mm for maximum efficiency. If your loft is used for storage, we typically recommend around 200 mm to keep the space practical while still improving performance.
During your free survey, we’ll assess your existing insulation and advise on the ideal depth to balance efficiency, comfort, and usable space.
Why Loft Insulation Matters
Without proper insulation, as much as 25% of heat escapes through your roof. Upgrading your insulation helps you:
Stay warm in winter
Keep bedrooms cooler in summer
Reduce heating bills
Improve your home’s EPC rating
For Windsor’s many older properties — from Victorian terraces to character homes near the Long Walk — insulation makes an immediate, noticeable difference.
