What is SuperFOIL Multi-Foil Insulation?
SuperFOIL is a high-performance multi-layer reflective insulation designed to dramatically reduce heat loss while maintaining a slim profile. Unlike traditional mineral wool, SuperFOIL works by reflecting radiant heat back into your home as well as reducing conductive heat transfer.
It is made up of multiple layers of aluminium foil, thermal wadding, and vapour control membranes. This layered system creates a powerful thermal barrier that performs exceptionally well in lofts, rafters, and room-in-roof properties.
SuperFOIL is ideal for Swansea homes where space is limited, such as loft conversions or properties with shallow rafters, because it delivers high thermal performance without requiring excessive thickness.
Benefits of SuperFOIL Insulation
-
📏 Space-Saving Design
SuperFOIL delivers excellent thermal performance in a much slimmer build-up than traditional insulation. Perfect for loft conversions where headroom matters.
-
🔥 Reflects Radiant Heat
The reflective foil layers bounce heat back into your home during winter and reduce overheating in summer, improving year-round comfort.
-
💧 Built-In Vapour Control
Acts as a vapour control layer when properly installed, helping to reduce condensation risks in loft and roof spaces.
-
⚡ Fast Installation
Installed directly across rafters or joists with sealed joints for maximum performance. Most Swansea homes completed within a day.
-
🌡 Year-Round Energy Efficiency
Reduces heating costs in winter and helps prevent loft overheating in summer, making your home more energy efficient throughout the year.
Our Installation Process
We follow a professional 4-step process to ensure optimal performance:
Free Home Assessment
We inspect your loft or roof structure, check rafter depth, ventilation, and suitability for multi-foil insulation. You receive a clear, no-obligation quote.
Preparation
We ensure proper ventilation paths are maintained and prepare surfaces for correct installation, sealing any obvious air leakage points.
Professional Installation
SuperFOIL is installed across rafters or joists with carefully sealed overlaps and taped joints to maximise reflective performance and airtightness.
Final Inspection
We inspect all joins, confirm ventilation is correct, clean the workspace, and ensure everything meets current UK building standards.
Frequently Asked Questions
SuperFOIL is ideal where space is limited or in loft conversions. Mineral wool is better suited to traditional flat loft floors. We’ll recommend the right solution during your survey.
Depending on the product used, SuperFOIL can achieve excellent thermal performance at significantly reduced thickness compared to 270–300mm mineral wool builds.
Yes. When installed correctly and combined with proper ventilation, SuperFOIL systems can meet UK thermal requirements. We ensure full compliance.
Yes – SuperFOIL is commonly used in room-in-roof applications because it preserves internal space while improving insulation performance.
Most Swansea homes can be completed in one day, depending on loft size and access.
