ENGINEERED TO BREATHE

For many decades, roof decks have been safely protected by breathable asphalt felt underlayments. Breathable roof protection has a long established history of use, backed by decades of building envelope science, and proven in real world conditions and all climates. Nearly all of the synthetic underlayments on the market fail to replicate this and do not breathe. Breathex is the next step in the evolution of roof protection because it is engineered to breathe.

Breathable roof protection has a long established history of performance.

Breathex is the first synthetic underlayment that makes no sacrifices, bringing with it all the reliability and proven properties of felt, but made with truly cutting edge synthetic construction.

HOW BREATHABILITY WORKS

Breathability Diagram

Breathex's hydrophilic polymer coating allows the water vapour in humid air to move through the sheet, but stops liquid water. This coating has no perforations, it is completely solid. It works by allowing the hydrogen in vaporous water molecules to temporarily bond with the polymers in the coating, migrate through the membrane, and then evaporate from the other side.

BEST IN CLASS WALKING SURFACE

Breathex Walking Surface Texture

Breathex textured walking surface.

The top side of Breathex is constructed out of textured, non-woven, polypropylene fibres, arrayed to ensure that rain or shine, Breathex has a secure walking surface. When the fibre strands are textured and overlaid like this they make a high friction surface that gives your boots plenty of traction, that when combined with proper footwear and fall protection, ensures a safe installation environment.

The textured fibres make a high friction surface that gives plenty of traction.

Because our non-woven is made with state-of-the-art technology, we are confident that Breathex has the best walking surface on the market.

UNDERSIDE COATING THAT GRIPS

The bottom side of Breathex is our custom monolithic breathable polymer coating, which provides a tough, rubber like backing with just the right coefficient of friction, helping the sheet stay in place as it's rolled out and when under foot, but not so much that it can't be repositioned as needed.

Breathex stays in place, but remains easy to reposition as needed.

The coating mimics the natural benefits of felt, and it is what sets breathex apart from the competition, by both allowing the membrane to breathe and by keeping it waterproof.

STATE-OF-THE-ART TECHNOLOGY

Breathex is made on the most advanced synthetic production line in the industry, taking advantage of the best possible technology to protect your roof. The spun bonded layer of Breathex is manufactured with Omni Directional strength, meaning it is nearly equal in strength in all directions, resulting in a much more predictable and strong product in the real world.

Breathex is manufactured on the most advanced, synthetic production line in the industry.

Spun bonded polypropylene is a green product that is harmless to the environment and poses no health concerns. This non-woven process is combined with our tightly controlled, laser monitored breathable coating application. This combined process ensures that Breathex lives up to HAL Industries' four decade long commitment to manufacturing the highest quality protective construction membranes.
