Your home deserves the best – DuPont™ Tyvek® Supro Plus Roof Underlay

 

 

DuPont Tyvek Supro

Underlays are an important element of high quality pitched roof and cladding construction. Although these membranes only make up an extremely small part of the total thickness of wall and roof structures, their function in terms of building physics are absolutely vital, and must be preserved for the lifetime of the element they are part of.

  • An underlay must facilitate absolute watertightness of the roof and wall
  • An underlay must protect the insulation thus promoting energy efficiency
  • A breather membrane is an important element in maintaining a healthy indoor climate over many years.

Whether underlays are supplied as single layer or multi-layer, it is the quality and the thickness of the functional layer which takes care of windproofing, waterproofing and vapour breathability. Quality and thickness also determine the durability of the membrane as a whole.

However resistant to tearing or elongating during installation a product may be, it can take only a few weeks for key functionality of watertightness to be degraded.

What are the risks when an underlay fails?

  • Building structure degradation
  • Mould and mildew
  • Indoor water damage
  • Insulation inefficiency

Don’t risk your roof with anything that won’t stand the test of time

DuPont™ Tyvek® Supro is the only Synthetic roof underlay with a durable functional layer, 5 times thicker than the others on the market – able to withstand the construction environment without compromising performance and in-service durability.
