If you’re looking to make your home warmer, more energy efficient, and even increase its value, insulating your loft is one of the smartest improvements you can make. With energy prices on the rise and a growing focus on sustainability, more UK homeowners are exploring modern solutions like multifoil insulation to get the best results.
Why Insulate Your Loft?
A quarter of a home’s heat can be lost through an uninsulated roof, according to the Energy Saving Trust. By adding insulation, you create a barrier that keeps warmth in during winter and helps your home stay cooler in summer. This not only makes your living space more comfortable but can also save you up to £270 a year on energy bills in a typical semi-detached house.
The Rise of Multifoil Insulation
While traditional options like mineral wool rolls and rigid boards are still widely used, multifoil insulation is becoming increasingly popular for its unique combination of performance and practicality. Multifoil insulation is made up of multiple layers of reflective foil and insulating wadding, designed to reflect radiant heat and provide a vapour barrier in one slim package. This makes it ideal for both new builds and retrofits, especially where space is at a premium.
Spotlight on SuperFOIL SF19+ and YBS SuperQuilt
Two of the leading products in the UK are SuperFOIL SF19+ and YBS SuperQuilt. Both are designed to deliver high levels of thermal performance in a much thinner profile than traditional materials.
SuperFoil Sf19+
SuperFOIL SF19+ is a 45mm thick multifoil insulation with 19 layers, offering a thermal resistance of up to 2.97 m²K/W for roofs. It’s made from recycled materials and is fully recyclable at the end of its life, making it a sustainable choice. You can find technical details and certifications on the SuperFOIL website.
YBS Superquilt
YBS SuperQuilt is another top performer, with 19 layers and a slim 40mm profile. It’s BBA certified and suitable for roofs, walls, and floors, providing a certified thermal resistance of up to 2.50 m²K/W. More information is available on the YBS Insulation website.
Both products are lightweight, easy to install, and act as a vapour control layer, helping to prevent condensation and mould—common issues in UK lofts.
Key Benefits of Multifoil Insulation
1. Space-Saving Design
Multifoil insulation is much thinner than traditional mineral wool or rigid boards, so you can maximise your loft space for storage or conversion. This is especially useful in properties with limited headroom.
2. Superior Thermal Performance
By reflecting radiant heat, multifoil insulation helps keep your home warmer in winter and cooler in summer. Both SuperFOIL SF19+ and YBS SuperQuilt are designed to meet or exceed UK building regulations for thermal efficiency.
3. Moisture Control and Mould Prevention
The built-in vapour barrier helps prevent condensation, reducing the risk of damp and black mould. This is particularly important in the UK’s damp climate.
4. Easy Installation
Multifoil insulation is lightweight and flexible, making it easier to handle and install than bulky traditional materials. Many homeowners choose to fit it themselves, but professional installation is also available.
5. Longevity and Durability
Both SuperFOIL SF19+ and YBS SuperQuilt are designed to last the lifetime of your property, with robust guarantees and minimal maintenance required.
6. Environmentally Friendly
With recycled content and full recyclability, these products are a sustainable choice for eco-conscious homeowners.
