Bubble Foil Insulation - Radiant Barrier & Secondary Insulation
SuperFOIL bubble foil insulation products provide an effective radiant barrier and secondary insulation layer in a lightweight, space-saving format.
Designed for roof, wall and floor applications where radiant heat reflection, moisture resistance and ease of installation are required as part of a protected construction build-up.
Key points:
- Reflective bubble foil construction providing radiant heat control.
- Helps reduce heat loss and solar heat gain when installed with adjacent air spaces.
- Lightweight and flexible – ideal for simple installations and upgrades.
- Suitable for garages, outbuildings, sheds and secondary insulation applications.
- Can be used alongside other insulation materials in hybrid build-ups.
- Manufacturer-tested and building regulation compliant where applicable
Important:
Bubble foil insulation products are primarily designed to act as a radiant barrier and secondary insulation layer.
They are not intended to replace high-performance multifoil or breathable insulation systems where higher thermal resistance or vapour control is required.
U-Value calculation & regulatory compliance
Thermal performance depends on the full construction build-up. Use the official SuperFOIL U-Value Calculator (available on the Home Page or Product Page) to verify compliance and optimise your insulation design.
