Multifoil insulation

Made from multiple layers of reflective foil and insulation wadding, multifoil insulation is designed to create a barrier against heat loss and cold bridging. Unlike traditional bulk insulation, it reflects radiant heat while also providing a protective vapour control layer. This makes it ideal for loft conversions, timber frame buildings, and refurbishments where space is limited. Historically, foil insulation rolls were used in aerospace and industrial applications before being adapted for construction to meet modern energy efficiency standards.

Builders choose thermal foil insulation for its versatility and ease of installation. Lightweight and flexible, it fits neatly into tight spaces, reducing material waste and labour time. It’s especially useful in retrofitting older properties, where keeping heat in and moisture out is essential.
