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, low-weight design. It is an excellent 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.
• Multi foil 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.

Always check whether the manufacturer has special instructions for a specific application. Generally, the installation follows a two-step process:

1. Fix the roll to rafters or battens with staples or suitable fixings.
2. Seal all joint overlaps with foil tape for airtight coverage.

How good is multifoil insulation?

Multifoil insulating products provide excellent thermal and reflective performance in compact spaces, thanks to their slim build. They are especially effective when used in conjunction with other insulation materials for enhanced performance.

How to install multifoil insulation

Follow these steps to install your multifoil insulation:

• Step 1: Cut the roll to size
• Step 2: Install the multifoil layer tightly against rafters, joists or walls.
• Step 3: Overlap joints by at least 50mm.
• Step 4: Secure tightly with staples or mechanical fixings.
• Step 5: Seal all seams to maintain airtightness and vapour control.
• Step 6: Finish with plasterboard or cladding.
