What depth of loft insulation do I need?
Current Building Regulations Part L recommend 270mm total depth for mineral wool loft insulation. SuperFOIL multifoil achieves equivalent performance at just 40-60mm.
How long does loft insulation installation take?
Most standard loft insulation installations take half a day to a full day. SuperFOIL for a loft conversion typically takes one to two days.
Will loft insulation reduce my energy bills?
Yes. A poorly insulated loft can account for up to 25% of a home’s total heat loss. Properly installed loft insulation typically reduces heating bills by 15-25%.
What is SuperFOIL multifoil insulation?
SuperFOIL is a multi-layer foil insulation that reflects up to 97% of radiant heat. It provides excellent thermal performance in a slim profile, ideal for loft conversions with limited rafter depth. Warm Lofts are SuperFOIL Installers.
Can I install loft boarding over my insulation?
Yes, but correctly. Laying boards directly on insulation compresses it and reduces performance. WarmLofts uses raised loft boarding systems that sit above the insulation, preserving the full depth and thermal performance.
Are Warm Lofts experienced installers?
Yes. Warm Lofts are SuperFOIL installers and Knauf installers, certified to install both product ranges to manufacturer specifications
Do I need to remove old insulation before installing new?
Not always. If existing insulation is clean and in good condition, it may be possible to top it up. However, if it is degraded, water-damaged, or contaminated, Warm Lofts recommends removal first. We offer safe fibreglass removal as part of our service.
