Multifoil Insulation – 40mm – Residential & Commercial

Product Overview

This 40mm thick high-performance multifoil insulation is designed for insulating pitched roofs, lofts, walls, and floors where a flexible multilayer reflective quilt is required. It combines multiple reflective foils and insulating wadding layers to reduce heat transfer across building elements. The quilt is lightweight, easy to handle, and conforms smoothly to irregular surfaces, making it ideal for installation in walls, roofs, and floors.

Its reflective outer layers help reduce radiant heat loss, while the layered internal structure provides thermal resistance across the insulation zone. Supplied in a 15m² roll format offering extended coverage for larger installation areas.

Features & Benefits

• Flexible multilayer construction: Conforms to uneven surfaces and complex junctions.
• Reflective foil facings: Reduce radiant heat transfer and enhance thermal efficiency when used with airspaces.
• Lightweight quilt design: Supports quick installation and easy maneuvering on-site.
• Layered insulation core: Multiple wadding and foil layers deliver combined thermal resistance.
• Application suitability: Suitable for walls, roofs, and floors where flexible multifoil insulation is required.
• Thickness: 40mm quilt thickness suitable for typical multifoil insulation requirements in domestic and light commercial projects.

Applications

• Pitched roofs: Suitable for warm roof, hybrid, or vented roof build-ups.
• Loft and ceiling zones: Enhances thermal performance in lofts and ceiling areas.
• Framed walls: Fits within timber or metal studwork as a flexible insulation layer.
• Floor zones: Can be installed over or between joists where permitted by the system design.

Installation Guidance

• Unrolling: Unroll the quilt across rafters, studs, or joists, allowing slight tension for a smooth finish.
• Cutting: Trim with scissors or a knife for clean edges.
• Fixing: Staple to timber members at recommended intervals; overlap layers where required.
• Joint sealing: Seal joints, laps, and perimeters using approved reflective tapes for continuity.
• Safety: Use appropriate PPE and follow manufacturer installation instructions.

Compliance & Performance

• Material: Flexible multifoil quilt combining reflective foils with insulating wadding layers.
• Thermal performance: Assessed to relevant thermal performance standards.
