Home improvement insulation designed to reflect heat back into rooms, cutting wasted energy. BLOSTM Foil Insulation Roll helps make cold corners cosier, ideal for anyone tired of chilly skirting boards and cold radiators. Is this the straightforward upgrade that will make your heating work smarter?
⚡ At a Glance
- • Thermal Performance: Reflects 97% of radiant heat back into the room using a reflective aluminium surface
- • Best for: Homeowners and DIYers fitting radiator backing, lofts, garages, greenhouses or pet hutches
- • Not ideal for: Applications that require pre-fitted adhesive pads, since adhesive pads are not included
Laminated aluminium bubble insulation, 1m by 25m and 2.4mm thick, functions as a thermal and vapour barrier. Suitable for year-round use in damp or dry areas thanks to anti-oxidation coating and water resistance.
Improved heat retention - with a reflective laminated aluminium layer
A laminated aluminium surface reflects radiant heat rather than absorbing it, and the bubble core reduces conductive heat transfer. The product specification states 97% heat reflection, creating a thermal barrier behind heat sources.
Less heat escapes through walls and behind radiators, so rooms stay warmer for longer and central heating need not run as often. That translates into lower energy waste and more consistent room temperatures.
Moisture and mould resistance - thanks to anti-oxidation coating and vapour barrier properties
An anti-oxidation coating on the aluminium layer improves resistance to corrosion in humid environments, while the foil acts as a vapour barrier to limit moisture movement. Product notes describe suitability for damp areas and resistance to water and mould.
Suitable for use in bathrooms, cellars or barns where humidity is present, the material helps protect underlying structures from damp-related damage. It reduces the need for frequent maintenance in moisture-prone locations.
Quick, adaptable installation - with a lightweight bubble construction
A 2.4mm bubble core provides flexibility and cushioning, while the roll format, 1m by 25m, allows for easy cutting and fitting to irregular spaces. The material is lightweight, so handling and positioning is straightforward.
Cuts easily to size for radiator reflectors, loft lining or floor underlay, so installation is practical for DIYers. Minimal maintenance is required, usually only occasional dusting to keep surfaces clean.

❓ Frequently Asked Questions
Q: Does it really reflect heat back into a room?
A: Yes, the foil is advertised to reflect 97% of radiant heat back into the room, using a laminated aluminium surface to reduce heat loss.
Q: Can it be used in damp or humid spaces?
A: Yes, the material has an anti-oxidation coating and is described as water and mould resistant, making it suitable for use in damp areas.
Q: Are adhesive pads included for sticking behind radiators?
A: No, adhesive pads are not included with the roll, so separate fixing materials will be needed for radiator installation.
🏆 Our Verdict
The BLOSTM Foil Insulation Roll is ideal for homeowners and DIYers wanting a practical way to reduce heat loss behind radiators and in small spaces. Reflective laminated aluminium, with a 2.4mm bubble core and anti-oxidation coating, combines thermal reflection with moisture resistance for versatile use. While initial effort is required to fit and source fixings, the likely energy savings make it a sensible long-term investment.
