Over-Foil RAD – Reflective Thermal Insulation Sheet
Key advantages
• Reflective thermal insulation sheet
• 100% pure aluminium on both sides
• Reflects up to 95% of radiant heat
• Lightweight, flexible and easy to install
• Acts as a vapour barrier
• Reduces condensation and moisture build-up
• Suitable for summer and winter
• Made in Italy
Why this product
Over-Foil RAD is designed to improve the thermal insulation of buildings by reflecting radiant heat, with a minimal thickness of only about 3 mm.
It reduces heat loss in winter, limits heat gain in summer and also acts as an effective vapour barrier, helping to improve thermal comfort and reduce condensation and moisture build-up.
Technical description
A reflective thermal insulation sheet supplied in rolls, consisting of a polyethylene core of inert air bubbles faced on both sides with protected 100% pure aluminium foils.
The multilayer construction provides high radiant heat reflection, acts as a vapour barrier and delivers effective thermal insulation while remaining flexible, lightweight and simple to install.
Applications
• Tiled roofs
• Metal roofs
• External and internal walls
• Ceilings
• Attics
• Private buildings
• Industrial buildings
• Warehouses and commercial buildings

Acoustic performance
• Provides some acoustic improvement as part of a building system.
• Designed primarily for thermal insulation and radiant heat reflection.
• Not a dedicated acoustic solution; we recommend combining it with sound insulation materials as required.
Fire performance
• The manufacturer does not state a reaction-to-fire classification in the technical document for this product.
Standards
• Origin: Made in Italy.
Installation
• Install with an air gap for optimum thermal performance.
• Can be installed in walls, roofs and ceilings.
• We recommend sealing the joints with dedicated aluminium tape.
• Maintain the continuity of the vapour barrier layer.
• Easy to cut and quick to install thanks to the material’s flexibility.
