Cromar Vent3 Light is a highly durable and efficient breather membrane with triple-layer fabric construction. It primarily comprises spun-bonded polypropylene layers with a micro-porous polypropylene film in between. This innovative design suits various roof systems, including fully supported or unsupported tiled, slated, or metal roofs. The membrane excels in both vapour permeability and waterproofing capabilities. It allows moisture vapour to pass through while maintaining complete waterproofing integrity.
Additionally, it offers exceptional tensile and tear strength, as well as high resistance against wind uplift. These outstanding features make Vent3 Light the preferred choice among professionals as the ultimate breather membrane for roofing applications. It can be draped unsupported over rafters or laid directly over insulation, providing flexibility in installation methods.
The outer layer is the functional waterproof surface, while the middle layer is the breathable waterproof membrane. Furthermore, the inner layer safeguards the membrane from abrasion and damage while adding extra strength. This comprehensive design ensures optimal performance and longevity of the fabric.
The upper surface of Vent3 Light is Dark Grey and includes printed trade names and head lap lines for easy identification and installation. It is available in standard widths of 1.0m and 1.5m, allowing for easy adaptation to various roof configurations and installer preferences.
