EPDM roofing membranes
EPDM excels in a wide range of temperatures and conditions and demonstrates superior UV and weather resistance as well as sheet flexibility and high elongation. EPDM membranes are available in several thicknesses, with or without polyester scrim reinforcement, and can be installed in ballasted, mechanically fastened or adhered applications. With wide widths and fewer seams, EPDM systems improve efficiency during installation. EPDM offers a quick, clean, inexpensive solution.
What are Thermoset Membranes?
Thermoset membranes are vulcanized, or chemically cross-linked. In this process, curatives or sulfur are added to rubberized materials which makes them more durable through crosslink chains. These materials are much less gummy than thermoplastics yet have superior mechanical assets. Thermoset membranes come in five distinct subtypes, but the most common is EPDM – comprised mainly of propylene and ethylene and comes primarily in 7.5 – 50 foot wide sheets which are 45-60 mils in thickness. Liquid adhesives or tapes are normally used to seal the seaming of EPDM membranes, and the colors are white or black.
Many thermoset roofs are either ballasted or fully adhered, although some larger commercial applications may prefer the optional mechanical attachments. When you generally hear someone discussing ‘rubber roofs’, they are usually talking about EPDM roofing materials.
Why It Works Well
Commercial building owners who wish to apply roofing materials for longevity would prefer the thermoset membranes due to their stronger manufacturing qualities over other single-ply membranes. This material also works perfectly in all climates, is great for flat roofs, and doesn’t easily wear down. In cold-weather climates, black thermoset membranes will absorb heat, whereas in warmer climates, white membranes are recommend to reflect this heat load. Finally, this material is cost-effective in accordance with how long it will last the building owner.
Would This Material Work For My Commercial Building?
Deciding on the proper long-term roofing system depends on various factors: climate, visual appeal, warming/heating properties, building characteristics, and so on. RPC Industries, Inc. can inspect your roof in relevance to various factors and make several recommendations to you. Thermoset membranes do possess many great characteristics, with durability leading the way.
