Home insulation designed to cut heat loss around radiators and across rooms. Designed for households and DIYers who want warmer rooms and lower heating waste, BLOSTM Foil Insulation Roll. Will the ease of fitting and reflective performance produce noticeable savings over the long term?
⚡ At a Glance
- • Thermal Performance: Reflective laminated aluminium with bubble foil reflects 97% of radiant heat
- • Best for: Homeowners and DIYers looking to reduce heat loss around radiators and in lofts
- • Not ideal for: Installations that require pre-applied adhesive pads, since pads are not included
Laminated aluminium bubble foil supplied as a 10m by 0.6m roll with 2.4mm thickness. Designed to act as thermal insulation, radiant heat reflector and vapour barrier.
Lower heat loss, with a highly reflective aluminium surface
Laminated aluminium faces on bubble foil reflect radiant heat rather than absorb it, so less energy escapes through walls and behind radiators. The construction produces a radiant barrier that returns heat into living spaces.
Warmer rooms for longer periods without increasing boiler output, helping reduce wasted energy from radiators and exposed surfaces.
Custom fit for awkward spaces, with a flexible roll format
Supplied as a 10m by 0.6m roll that is lightweight and easy to cut to size using a utility knife or scissors. Panels can be trimmed to fit behind radiators, in lofts, on walls or inside pet hutches.
Quick DIY installation for odd shapes and tight gaps, enabling neat coverage around pipes and across skirting boards.
Suitable for damp or humid locations, thanks to anti-oxidation coating
Aluminium faces include an anti-oxidation coating and the bubble foil resists tears and punctures, maintaining stability in high humidity. The material is described as water and mould resistant.
Reliable performance in basements, garages or other humid spaces where moisture could damage lesser insulation options.

❓ Frequently Asked Questions
Q: Does the foil really cut heat loss behind radiators?
A: Reflective laminated aluminium reflects 97% of radiant heat back into the room, reducing the amount of heat lost through walls and behind radiators.
Q: How is the roll installed and are fixings included?
A: The roll is lightweight and simple to cut to size for DIY installation, but adhesive pads or other fixings are not included and must be sourced separately.
Q: Is the material suitable for damp areas like basements or garages?
A: The laminated aluminium has an anti-oxidation coating and the bubble foil is described as water and mould resistant, remaining stable in high humidity.
🏆 Our Verdict
Ideal for homeowners and DIYers who want a straightforward way to reduce heat loss around radiators, in lofts and across rooms. High reflectivity combined with a vapour barrier and anti-oxidation finish helps keep rooms warmer and resists damp-related deterioration. Good long-term value for energy-conscious households, as reduced heat loss can lower running costs over time.
