Actis Boost-R Hybrid Multifoil Breather Membrane - 10.67m x 1.5m x 35mm

Multi-foil insulation is a type of thermal insulation material composed of several layers of reflective foil, often with additional materials such as foam or bubble wrap sandwiched in between. The reflective foil layers work by reflecting radiant heat, preventing it from entering or escaping a building, thus helping to maintain desired temperatures and improve energy efficiency. This type of insulation is popular for its lightweight and flexible nature, making it easy to install in various construction applications, such as roofs, walls, and floors. Multi-foil insulation is known for its high thermal performance and is often chosen for its effectiveness in reducing heat loss or gain in buildings.

A breather membrane, also known as a vapour-permeable membrane, is a type of building material used in construction primarily for its ability to allow moisture vapour to pass through while preventing liquid water from penetrating into the structure. It is typically installed on the external side of a building's insulation, beneath the external cladding or roofing materials. Breather membranes help to manage moisture within the building envelope, reducing the risk of condensation and mould growth while improving energy efficiency by allowing buildings to "breathe" and maintain a balanced internal environment.

Actis Boost-R is designed for use on the “cold” side of buildings, and is typically installed using battens and counter battens to hold the rolls in place. Designed to be applied horizontally in a continuous roll in most situations, cut around windows and doors with sharp scissors or craft knife. Install with an overlap finished with insulation tape to ensure an airtight finish. Easily secure to board or battens with a staple gun.
