Bubble Foil Insulation Roll – 4mm Thick Multi Purpose & Radiator Reflector Panels

Description

If you’re looking for a simple way to cut your energy costs, putting foil insulation behind radiators is one of the most effective tricks that actually works. Our 4mm thick bubble foil reflects heat back into your room instead of letting it disappear through the wall, helping your space warm up faster and stay warmer for longer.

Why 4mm Makes a Difference
At 4mm thick, this foil insulation is chunkier than the typical 3mm versions you’ll find elsewhere. That extra thickness means better durability and improved thermal performance. The double reflective aluminium surfaces bounce over 95% of radiant heat back where you want it – that’s heat you’re already paying for.

Works Beyond Just Radiators
While it’s brilliant for radiator applications, this bubble foil insulation has loads of other uses around the home and beyond. People use it for van conversions, shed insulation, garage doors, loft spaces, and even as window reflectors in summer to keep rooms cooler. The 3-in-1 design works as thermal insulation, heat reflector, and moisture barrier all in one product.

Simple Installation
The 0.6m width is perfect for most radiators and easy to handle during installation. Just measure what you need, cut it to size with scissors or a craft knife, and position it where required. The PE air bubble core with aluminium foil faces gives you effective insulation that’s light enough to stick up easily but tough enough to last.

Choose Your Length
Available in three roll lengths to match your project needs:

• 5m roll – covers a couple of standard radiators
• 10m roll – ideal for most home applications
• 20m roll – great value for larger projects or multiple applications

Whether you’re trying to make your house more energy efficient, working on a van conversion, or insulating a workshop, this bubble foil insulation delivers reliable performance without breaking the bank.
