On the show floor, just beyond the demo noise. A product manager from a roofing membrane manufacturer taps the roll core with a knuckle and asks, “Will this carrier behave the same on day 4,000 as it does on day 4-and will the roof still lie flat when the seasons start pulling?”
It’sthe kind of question we heard more than onceat the International Roofing Expo (Jan 20–22, Las Vegas).IRE is the annual hub where roofing and exteriors swap what works-hands‑on demos, real education, and conversations that calibrate the industry’s compass for the year ahead.We were thereroaming the floor and the meeting rooms, listeningforthe decisions that shape materials upstream-on your production line-before anyone steps on a roof.

At 鶹ֱapp Engineered Products, we engineer glass and polyester nonwovens that sit at the heart of modern roofing systems-carriers for modified bitumen membranes, glass mat facers forpolyiso/gypsum deck boardsandbase mats forroofingshingles.We co‑develop withmanufacturers,so the mat runs clean on the line and stays calm on the roof-stable, weldable, and ready for real‑world weather.


Below are three questionsfrom IREthatmanufacturers asked us most-and how our Evalith® fiberglass and polyester nonwovens help you answer them with confidence.
1) “Will the reinforcement keep the roof calm through seasons?”
What’sreally being asked:When temperatures swing and abuilding moves, will the membrane resist wrinkling and creep, keep seams quiet, and preserve surface aesthetics?
How Evalith® helpsbituminousroofingmembranes:
- Fiberglass mat carriers have no thermal memory, which helps sheets relax quickly and stay dimensionally stable after installation-translating to fewer wrinkles over time and seams that behave.
- Where a roof must flex with the structure, polyester spunbond adds elasticity and tear strength, helping the membrane stretch and recover rather than crack-useful in SBS systems designed for movement.
Rui Ferreira(Director Nonwovens Technology):“Owners never ask abouttensilestrength or dimensional stability. They are moreconcernedwhether their roof will leak in ten years from wind or weather exposure.That'show JM's products pay dividends.”

2) “Will the deck facer protect the system when schedules-and weather-test it?”
What’sreally being asked:Do the deck panels bring the bond strength, moisture/mold resistance, fire performance, and winduplift confidence that keep the rest of the system out of trouble?
How Evalith® helpsroof-deckpanels:
- Evalith® fiberglass mat facers add mechanical integrity for dimensional stability and strength, support excellent adhesion to the core (less prone to delamination during installation), and theiroptimaldensity enables clean handling and precise cutting.
- Facers increase a panel’s resistance to water, mold, and fire, handle humidity and temperature swings, can be exposed toharsh environmental conditionsduring construction without deterioration, help protect against wind uplift, and are highly suitable for mechanically fastened systems.
Ellen Reed(ProductManager):“If the deck stays strong and the facer keeps its bond, the downstream layers can do their jobs-no drama at the edges, no surprises at inspection.”

3) “Will theshinglereinforcing matstand up to storms-and the lab?”
What’sreally being asked:Can the shingle substrate support winduplift, tear resistance, fire performance, adhesion, weathering, and lowtempflexibility-not just on test day, but across seasons?
How Evalith® helpsroofing shingles:
- Evalith® fiberglass mat for roofing shingles provides a uniform, thin‑but‑strong substrate that accepts asphalt cleanly and supports tear strength and winduplift resistance in the finished shingle-backed by consistent MD/CD behavior and binder systems that limit fiber shedding during production.
- Themat’sprofile is designed for clean impregnation and reliableadhesionwith the asphalt, including back‑side tape adhesion, helping shingles keep their shape and seal through weather exposure and seasonal temperature swings on the roof.
Rick Hausman(Commercial Leader):“Shingleshave tostand up to wind, hail, and fire - and keep doing it for years. Our mats make those results dependable for manufacturers and reassuring for homeowners.”

Why manufacturers work with JM EP
- Performance that shows up on roofs:Evalith® carriers and facers are engineered for dimensional stability, strength, and environmental resistance- properties that translate into longlife membranes, deck panels, and shingles.
- Strategic manufacturing in Europe & North America:Self‑sourced in fiberglass with nonwoven plants in Etowah, TN; Waterville, OH; Wertheim, Germany; and Steinach, Germany, plus polyester spunbond production in Spartanburg, SC; Berlin, Germany; and Bobingen, Germany - delivering supply security, shorter lead times, and flexible logistics worldwide.
- Service thatgoesthe #JMextraMile:Multilingual customer and technical support, fast sampling, and application guidance across roofing markets.
Anna Fuhrbach(Portfolio Manager):“Specs are promises. Our job is helping you keep them-on the line, and yearslater onthe roof.”
