History of Innovation
For decades, roof decks have been protected by roofing felt placed beneath shingles, shakes, and other types of roofing. Roofing felt is a naturally breathable sheet which allows humidity and moisture to escape from beneath it.
We looked to our industry leading line of roofing felts for inspiration when designing the original Breathex, and our breakthrough synthetic roofing underlayment product proudly carries on the proven tradition of breathability. While most synthetic underlayments can’t breathe, our Breathex membrane technology is engineered to breathe, preventing water from being trapped against the roof deck while still maintaining a solid waterproof barrier from rain and leaks.
Breathex is the first modern underlayment technology with no compromises. It brings with it all the benefits of tradition but is made of truly cutting-edge synthetic construction.
Breathex Pro is the next step in the evolution of roof protection. With Breathex Pro, we improved our original Breathex coating and created a new product with unparalleled uniformity and uncompromising quality. We added a third layer of spunbonded polypropylene for greater strength and reliability across all job sites.
MAINTAINING A DRY AND HEALTHY DECK
Attics can collect a steady flow of humid air from active living spaces below, and often through roof vents during repeated dewpoint morning. This humid air can raise the absorbed moisture content of roof plywood to a level where unhealthy mold growth can occur, especially if the moisture can’t escape from the upper side through a breathable underlayment.
The hydrophilic coating on Breathex Pro will absorb water vapour molecules from the roof deck below and release them to the shingle interface above where sun and wind action can disperse them each day.
Class Leading Walking Surface
The top side of Breathex Pro is formed out of nonwoven, spunbonded polypropylene fibres, textured so that rain or shine, Breathex Pro has a secure walking surface. This high-friction surface gives your boots plenty of traction, and when combined with proper footwear and fall protection, it provides a safer installation environment. Breathex Pro's walking surface is strong, durable, and specifically designed to give your feet excellent grip.
