DuPont Everon Vapour Permeable Roofing Underlay is a high-performance breather membrane designed to provide dependable weather protection while allowing moisture vapour to escape from the roof structure to reduce condensation risk. Lightweight yet durable, it offers excellent airtightness and W1 watertightness (EN ISO 811), with resistance to a water column of up to 7 metres to help protect against heavy rainfall.
Ideal for new builds, refurbishments and light commercial roofing projects, Everon combines strong nail tear and tensile resistance with easy handling on site. Supplied in a practical 1m x 50m roll, its printed installation grid helps improve cutting and alignment accuracy.
Question:
Is Everon a sustainable choice?
Answer:
Yes. Everon™ uses a patented, 100% recyclable construction, and its lighter, more flexible sheet is easier to handle and install, reducing effort on site while supporting more sustainable building practices.
Question:
Is Everon certified, warranted, and suitable for my project?
Answer:
Yes. Everon™ is CE-certified and carries a 10-year DuPont warranty. It's a Type LR reinforced underlay rated for all five UK BS5534 wind zones when installed with a taped lap and it performs in warm, hybrid, or cold pitched-roof constructions, whether ventilated or non-ventilated, covering the vast majority of standard residential and small commercial roofs.
Question:
Why choose Everon over a cheaper generic membrane?
Answer:
You get a membrane backed by DuPont, a 10-year warranty, a high water column for reliable weather protection, and the technical support that comes with the Tyvek® family, advantages most low-cost alternatives can't match at this price.
Question:
How is Evero different from Tyvek Supro?
Answer:
Both are Type LR reinforced underlays suitable for supported or unsupported use on pitched roofs. Supro is the premium option, built around a functional layer 6–8× thicker than typical multilayer products, with the longest warranty and extended UV and thermal resistance. Everon™ is lighter, more flexible, and easier to handle than other multi-layer products, delivering strong watertightness and DuPont reliability at a more accessible price point.
Question:
What is DuPont Everon and where does it sit in the range?
Answer:
Everon™ is a new DuPont mid-tier vapour-permeable roofing underlay for pitched roofs . It brings trusted DuPont quality and class-leading watertightness to the mid-market segment, sitting between entry-level membranes and our premium Tyvek® Supro. Think of Supro is the premium offer in the Dupont portfolio and Everon™ as the dependable mid-tier choice for standard residential and small commercial roofs.
