Kianco black roofing felt uses a special hydrophobic film that cannot become blocked by slate debris or suffer the reverse affect of static condensation. The performance of many membranes is reduced when the layers are stuck together but the special 3-to-1 thermal bond of Kianco black creates a durable breather membrane that cannot delaminate. High-grade materials combined with the worlds most advanced production shows that the lighter weight, strength and elasticity of Kianco black means that it can be used in any application to improve the performance of an alternative membrane.
