Procheck VCL125 is a high-performance vapour barrier and vapour control layer (VCL) designed to manage the movement of water vapour within building structures. Manufactured from a lightweight reinforced polyethylene with a durable multifilament scrim polypropylene reinforcement, it provides excellent strength, durability, and long-term performance.
Developed by Proctor, Procheck 125 helps protect insulation systems and building fabrics from moisture-related issues by controlling vapour transmission through walls, roofs, and floors. Its high vapour resistance reduces the risk of interstitial condensation, helping to maintain insulation effectiveness and improve overall energy efficiency.
This reinforced vapour membrane also contributes to building airtightness when correctly installed, making it an ideal solution for modern construction projects where moisture control and thermal performance are essential. Supplied in a practical 2m x 50m roll, Procheck VCL125 is suitable for residential, commercial, and industrial applications requiring a reliable and durable airtight membrane.
