This multi-foil insulation slab is designed for use in pitched roofs, loft conversions, stud walls, and both under-rafter and over-rafter applications. Its 105mm thickness and layered foil construction make it suitable where efficient thermal insulation and straightforward installation are needed on site.
Each slab covers a generous area, helping to minimise joints and simplify fitting between timber framing or across rafters. The lightweight, fibre-free composition supports cleaner handling and is practical for situations with limited access or overhead work, providing a consistent insulation barrier in domestic and refurbishment projects.
