Protect your buildings from mildew, staining and frost damage caused by interstitial condensation using this vapour barrier. It restricts the penetration of moisture into structures and increases the airtightness of buildings. As a result, this improves insulation and makes buildings more comfortable and energy efficient. This vapour barrier membrane is made of a thick polythene film, so it’s durable and contains no harmful materials. It should be installed along the warm side of a roof, wall or floor based on recommendations set in BS5250:2002 standards for the control of condensation in buildings. The barrier is especially useful in protecting bathroom and kitchen areas, as these spots tend to be highly prone to moisture build-up. Size: 4m x 25m Coverage: 100m2 Ultimate Moisture Defence – Stops water vapour, condensation, and damp in their tracks. Heavy-Duty 200 Micron Thickness – Durable, puncture-resistant, and built to last. Foil-Backed for Thermal Efficiency – Reflects radiant heat to improve energy retention. Multi-Use Application – Perfect for walls, ceilings, floors, attics, basements, and window reveals. Energy-Saving & Airtight – Reduces heat loss, boosts insulation performance, and enhances energy efficiency.
