Perfect Breathable Membrane

Perfect Breathable Membrane is a triple layer fabric, high performance breather membrane, made from high tensile spun bonded polypropylene layers, around a microporous polypropylene film. Designed for use in a fully supported or unsupported tiled, slated or metal roofsystem. The high vapour permeability and waterproof nature of the membrane combined with excellent tensile/tear strength and high wind uplift resistance make the professional's choice as the ultimate breather membrane. It is equally suitable whether draped unsupported over rafters, laid directly over insulation or sarking boards. The outer layer forms the functional waterproof surface, the middle layer is the breathable waterproof membrane, and the inner layer protects the membrane from abrasion and damage, also giving additional strength. This enables the fabric to allow moisture vapour to pass through, whilst remaining fully waterproof. Available in 1.0m and 1.5m widths as standard to conform easily to any typical roof configuration or the individual working practices of the installer.

OPERFECT offers a high-performance house wrap alternative similar to DuPont Tyvek.

Crafted from flash-spun, non-woven high-density polyethylene (HDPE), it functions as an essential weather barrier and air barrier for the building envelope. This durable, water-resistant, and wind-resistant material is also uniquely vapor-permeable, enabling effective moisture management and mold prevention within walls. Key properties like high tensile strength, tear-resistant nature, UV-stable performance, and being lightweight ensure easy installation and long-term protection for both residential construction and commercial buildings as exterior wall wrap. Supporting energy efficiency, code compliance, and green building initiatives, OPERFECT provides a robust solution for sustainable construction.
