EPDM
EPDM stands for ethylene propylene diene terpolymer. EPDM is a durable synthetic rubber roofing membrane that is used in low-slope buildings. It has two main ingredients which are ethylene and propylene.
Cost-Effective
Ballasted systems are cost effective because of the minimal amount of components. There is less material, labor, and energy used to install a ballasted system compared to other commercial roof systems.
Sustainability
EPDM membranes have high resistance to thermal shock, weathering, abrasion, and ozone and are flexible in low temperatures.
Durability
EPDM roof assemblies are designed to offer outstanding protection against UV exposure, hail damage, and extreme temperature fluctuations.
Types of Installation
JRC implements three main methods of EPDM installation. Fastened, Fully Adhered, and Ballasted. Each of these types have a number of benefits. Read about the different types below.
Fastened
In order to secure the single-ply membrane to the roof assembly, the membrane is attached with mechanical fasteners through both the insulation and decking material.
Fully Adhered
The single-ply membrane is attached to the topmost surface of the roofing assembly through the use of a bonding adhesive. This method secures the membrane across the entire roofing assembly.
Ballasted
When gravel, pavers, or vegetation is used to hold roofing components in place, the result is a ballasted roof. Ballasted roofs provide a natural-looking surface that blends well with a range of architectural styles.
