Smart Home Energy 
If you're renting or want a quick DIY heat-loss fix, this foil roll goes behind radiators, under rugs, or on cold walls to bounce heat back into the room — no builder, no mess, and pays for itself in months.
Problem it solves
Reduces heat loss through walls, floors, ceilings, and behind radiators by reflecting radiant heat back into the room, cutting the energy needed to maintain warmth.
Who it's for
Renters and homeowners looking for low-cost DIY insulation improvements, particularly those with solid walls, cold floors, or radiators on external walls where heat escapes easily.
Why we recommend
Easy to install and makes a decent dent in heat loss.
