Rubershield-Pro Extra is a IAB/BBA certified, premium performance breather membrane that allows potentially harmful moisture vapour to escape from within a building to the outside air, while remaining rain and water-resistant. A membrane that is suitable and approved for all types of roofing construction is a huge benefit, especially when it’s also lightweight, easy to handle, strong and durable.

Rubershield-Pro Extra conforms to the highest performance and professional standards. Designed as a fully supported or unsupported breathable underlay for tiled, slated or metal roofing systems, it’s equally suitable whether draped unsupported over rafters or laid directly over insulation or traditional sarking planks.
