Reflective Foil Insulation Roll 3.5mm 50x300cm, Campervan

A metal van body can turn into an oven in summer and a fridge in winter. This double-sided reflective foil insulation roll helps you tackle both problems, making it a practical material for campervan windows, motorhome panels and other areas where heat gain and heat loss make life on the road less comfortable. It is lightweight, flexible and easy to work with, even for first-time van builders.

The roll combines a 3.5 mm insulating cotton layer with aluminium foil on both sides. The reflective surfaces bounce radiant heat back, while the padded core helps slow heat transfer. It can be cut to shape with scissors or a knife, making it easy to create custom window covers, line storage areas or wrap pipes. The roll measures 50 x 300 cm, giving plenty of material for smaller projects.

It suits van converters, motorhome owners and caravanners looking for an affordable insulation upgrade, and it is equally useful for garage doors, roofs, rooms and pipework at home. Use it to make removable window screens for hot days or cold nights, or fit it behind panels as part of a wider insulation build. Clean and dry surfaces before fitting, and keep the material away from heaters and flames.
