Description
Vapour Barrier Membrane 125mu – 4m x 50m | Moisture Control & Condensation Protection
Protect your building from unwanted moisture with our 125mu Vapour Barrier Membrane, designed to help control the movement of warm, moisture-laden air from inside a property into the building structure. Suitable for residential, commercial and industrial applications, this high-quality vapour control layer helps reduce the risk of harmful interstitial condensation, improving the long-term performance of insulated walls, floors and roofs.
Manufactured from durable polyethylene, this 125-micron vapour barrier provides an effective barrier against moisture vapour, helping to maintain a dry, energy-efficient building envelope. It is ideal for use in new builds, extensions, renovations and insulation projects where vapour control is essential.
Each roll measures 4 metres x 50 metres, providing 200m² of coverage, making it suitable for both large and small construction projects.
Manufactured to high-quality standards, all of our vapour barrier membranes conform to ISO 9001 and have been independently tested to K124/02/95, giving you confidence in their performance and reliability.
