3mm Thermal Foam Insulation with Aluminium Coating | Camper Van, Shed & Garage Wrap

Ultra-Slim 3mm Reflective Foam Thermal Insulation

Optimise your space with our Premium 3mm Closed-Cell Foam Barrier. Combining high-density cross-linked polyolefin foam (EXPEL PETM) with a reflective aluminium coating, this insulation is the perfect solution when you need effective thermal protection without adding significant bulk.

Advanced Thermal Efficiency in a Slim Profile

Despite being only 3mm thick, this insulation reflects up to 90% of radiant heat. It distributes warmth back into your room in winter and keeps interiors cooler in summer. It also acts as a superior acoustic absorber, making it a favorite for van conversions where reducing road noise is a priority.
