Multifoil Insulation
Multifoil insulation is a high-performance, reflective insulating material suitable for roof, wall, and floor applications. It is an efficient and space-saving alternative to conventional insulation options.
What is multifoil insulation roll?
A multifoil insulation roll is a flexible, reflective material composed of several aluminium or metallised foil sheets and thermal padding. The layers work together to block heat transfer, giving excellent insulation in a slim, lightweight design. It is a practical option for roof, floor, and loft applications that require compact yet effective insulation.
What is multifoil sheet used for?
Multifoil insulation rolls are used across various applications:
- As multifoil loft insulation to keep roof spaces energy-efficient, especially in loft conversions where traditional rolls would be too thick.
- Multifoil roof insulation for pitched or flat roofs.
- Multifoil floor insulation to stop cold bridging through floors.
- Garden rooms, garages, and extensions.
- Wall linings and drylining systems can be used in cavity or timber frame constructions.
- Also ideal as part of a continuous insulation system or layered with other materials for hybrid performance.
The material’s flexibility makes it easy to install in both new builds and retrofits.
Types of multifoil insulation rolls
Multifoil insulation comes in several specialised formats to match different building layouts and performance needs:
- Roof multifoil insulation. Lightweight and vapour-resistant solution for roof spaces.
- Wall multifoil insulation. Adds radiant heat reflection to internal or external walls.
- Floor multifoil insulation. Designed to stop heat loss through ground floors. Adds heat retention with minimal height loss.
- Loft multifoil insulation. Optimised for tight spaces and attic projects. Offers strong thermal reflection.
- Hybrid multifoil systems. Combine foil layers with insulation cores such as foam, fibre, or bubble wrap. They also include vapour control for better acoustic and thermal performance.
Benefits of multifoil insulation
Multi foil insulants offer practical advantages, such as:
- Reflect up to 95% of radiant heat for year-round energy savings.
- Improve overall U-values when combined with air gaps.
- Thin, space-saving layers compared to bulk insulation.
- Can be cut easily and installed quickly.
- Works as a vapour control layer when taped and sealed.
- Durable multi-layer build resists tearing and wear.
- Enhance comfort in all seasons.
- Suitable for most roof, wall, and floor systems.
