The WOLFIN Vapour Permeable Roof Refurbishment Solution has been developed to eliminate the need to strip and dispose of the existing roofing membrane, insulation or vapour control layer.
The roof can be simply overlaid with the WOLFIN membrane.
With its unique formulation and black colour, the membrane rapidly heats up due to solar radiation.
This causes a high vapour pressure that gradually dries out the trapped moisture by forcing it up and through the WOLFIN vapour permeable membrane.
As the roof dries out, the thermal properties of the existing insulation are restored.
The WOLFIN solution is a 20 year insurance backed system which offers significant financial savings for commercial and public sector clients.
An independent costs analysis by Aecom assessed that a saving of circa 17-28% is possible in comparison to traditional refurbishment methods.
The solution also provides the opportunity to upgrade the thermal performance of the roof to meet the latest building regulations.
Additional insulation can be added above the existing failed roof prior to the application of the WOLFIN system.
