negating the requirement for traditional ventilation to Russia

The outside layer creates the waterproof surface, the mid layer is the breathable waterproof membrane, and the inside layer protects the membrane from any damage or abrasion, while offering additional strength. This allows the fabric to allow moisture vapour to pass through while remaining fully waterproof. The top surface is blue and printed with head lap lines and the trading name. It is available in 1.0m & 1.5m widths as standard, allowing it to conform easily to any roof configuration or the working practices of the installer.
