EPDM membranes create a flexible, durable waterproof barrier by forming a seamless surface.
Waterproof Barrier: EPDM membranes establish a continuous and seamless barrier across the roof substrate, effectively preventing water from penetrating the building structure beneath. This barrier is essential for safeguarding the interior from water-related damage, such as leaks, mold, and decay.
The installation of EPDM membranes is generally straightforward.EPDM membranes are typically applied in large sheets, which can be adhered to the substrate with adhesive, secured mechanically with screws and plates, or installed using the Induction System, a heat induction technology that resists punctures. Alternatively, they can be ballasted with gravel or pavers.
The seams between the sheets are sealed through methods such as hot air welding or vulcanization. Vulcanization involves connecting EPDM rubber sheets to form a custom-sized membrane with significant dimensions.
EPDM membranes exhibit remarkable flexibility, allowing them to stretch and adapt to building movements and temperature fluctuations without losing their structural integrity. Membranes possess an elasticity exceeding 500% and remain flexible at low temperatures down to -40°C.
This adaptability is particularly crucial in areas experiencing extreme temperature changes, as it mitigates the risk of cracking or splitting over time.
EPDM membranes resist UV radiation, ozone, and other environmental elements that typically degrade conventional roofing materials over time.This durability contributes to the extended lifespan of the membrane, ensuring long-term protection for the roofing structure.
EPDM is a recyclable material, and several manufacturers incorporate recycled content into their membranes. Furthermore, EPDM roofs can enhance energy efficiency by reflecting sunlight, thereby reducing cooling expenses.
After installation, EPDM membranes demand significantly less maintenance in comparison to other roofing options. Periodic inspections and minor repairs address any damage or wear, but overall, maintenance remains straightforward.
EPDM membranes demonstrate remarkable resistance to a variety of chemicals, including acids, alkalis, and industrial pollutants, rendering them ideal for industrial and commercial settings. They are permanently resistant to bird droppings, various chemical emissions, and other harsh environmental factors.
Membranes combine environmentally responsible materials, such as glass, EPDM, TPE, and bitumen, to enhance performance and sustainability. These roofing membranes contain no hazardous additives such as heavy metals, halogens, or volatile softeners, thus being classified as 100% non-toxic, with no harmful chemicals or questionable materials released throughout their entire lifecycle.
EPDM membranes deliver strength and longevity, lasting 30 years or more. With proper installation and maintenance, some membranes are certified to last up to 50 years.This characteristic makes them a financially prudent roofing choice over time.
They are compatible with a broad array of roofing accessories and components, including flashings, sealants, and insulation, facilitating seamless integration into diverse roofing systems.
In summary, EPDM waterproofing membranes create a robust, waterproof barrier over flat or low-slope roofs, safeguarding the building structure from water infiltration and environmental damage for many years.
