Klober Permo Sec Metal Vapour Permeable Waterproofing Barrier

Here at JJ Roofing, we have a sterling reputation for providing the very best materials and products so that you can take your roofing and construction projects to the next level. In keeping with this, we are happy to be able to offer the Klober Permo Sec Metal Vapour Permeable Waterproofing Barrier at extremely competitive prices. You won’t find a better range of products at such respectable prices anywhere else.

This example of vapour permeable waterproofing barrier is installed as a separating layer between copper, zinc, aluminium, and stainless steel standing seam roof finishes and the supporting deck underneath. You will be surprised at the difference it makes to the performance characteristics of the roofing section it’s professionally installed in.

Anyone who has tried to lay a metal standing seam roofing section knows that if the supporting deck and underlay aren’t smooth and regular, then the metal can deform and cause all sorts of issues. Fortunately for you, JJ Roofing can supply this fantastic solution which covers irregularities within the roof deck. This prevents the metal from deforming and becoming misshapen from the imperfections in the supporting deck.

You will find it hard to find a product that can give you the level of performance this can. It features a secondary layer which makes it fully waterproof and acts as a reliable barrier against water penetration. On top of this, the underlay is vapour permeable, so the roofing section is breathable.

It may be hard to believe, but this underlay also offers an acoustic value of 8db and acts to help reduce the intensity of external structure borne sounds, such as rain hammer and wind reverberation.
