Home insulation that reflects heat back into rooms to reduce heating losses and improve radiator efficiency, the BLOSTM Radiator Insulation Foil is a simple retrofit for older houses. Feel warmer in living spaces without changing radiators or pipework. Will the easy-fit, durable foil make a noticeable difference to household heating use?
⚡ At a Glance
- • Heat Reflection: Reflective laminated aluminium bubble foil that reflects 97% of radiant heat
- • Best for: Householders wanting a low-effort way to reduce heat loss from radiators
- • Not ideal for: Rooms where radiators sit away from walls or behind heavy furniture
Laminated aluminium bubble foil, 5m x 60cm, converts radiated heat back into the room. Supplied with adhesive pads and designed to be cut to size for multiple radiators.
Greater heat retention - thanks to reflective laminated aluminium foil
A metallic reflective layer combined with a 3.6mm bubble core reduces radiative heat loss by reflecting heat back towards the room surface. The air pockets in the bubble structure also slow conductive heat transfer through the wall.
More of the radiator's output ends up warming the room, allowing lower thermostat settings and reduced heat wastage.
Quick fit and customisable - with adhesive pads and cut-to-size design
Panels hang from existing wall brackets behind radiators and include adhesive pads for secure positioning, while the 5m roll can be trimmed with scissors to the exact width required.
Installation takes minutes and requires no specialist tools, making it straightforward to upgrade several radiators in one afternoon.
Built to last year-round - with anti-oxidation coating and robust laminate
A protective coating on the aluminium layer prevents oxidation and maintains reflectivity over time, while laminated construction gives mechanical strength against tears.
Low maintenance performance, suitable for continued use through winter and adaptable for window or reflector roles in warmer months.
