Easy to use - radiator reflectors are easy to use and install, simply cut the film to the required size and stick or fix to the surface. Self-adhesive design for long-lasting adhesion that won't come off easily and foldable design allows you to store easily.
Wide range of applications - Radiator foil insulation rolls can be used in both outdoor and indoor environments such as (wall insulation rolls, kitchen radiators, window insulation films, barrier covers, van insulation and heat reflective panels.
Warm in winter and cool in summer - In summer, the insulation foil bubble film reflects sunlight and insulates. It helps to keep the room cool even in strong sunlight. In winter, rooms stay warmer for longer because aluminium insulation film helps to keep the cold out and helps to retain heat rather than losing it.
