SpecTips: Carlisle’s 5′ SAT EPDM: A Game-Changing Single-Ply Alternative to Mod-Bit

High-rise and other hard-to-access rooftops have traditionally relied on modified bitumen (mod-bit) due to its manageable roll sizes that fit into freight elevators. However, mod-bit installations can be messy, time-consuming; and, in some cases, restricted due to regulations banning certain applications. While applicators prefer the efficiency of single-ply roofing, its larger roll sizes and adhesive requirements have historically left a gap in the market for these challenging installations.

Carlisle recently introduced a new 5′ x 40′ Self-Adhered Technology (SAT™) EPDM to meet the growing demand for an easier-to-install solution for hard-to-access, small, or cut-up roof sections; as well as vertical walls. Available in black and white and exclusively in 60-mil thickness, this innovative membrane features a factory-applied, 100% solid pressure-sensitive adhesive; ensuring consistent application while boosting productivity by up to 80%. The adhesive is low-VOC and eliminates jobsite odors, making SAT EPDM an ideal choice for occupied buildings and VOC-regulated areas.

SAT membranes are approved for direct application to common substrate boards, including DensDeck® Prime, SECUROCK®, and SecurShield® products; as well as clean concrete. For vertical applications, walls can be primed with CAV-GRIP® III or bonding adhesive.

Engineered for efficiency and convenience, the lightweight 5′ x 40′ rolls weigh approximately 80 pounds, making them easy to carry up stairwells or transport via freight elevators. Each pallet contains 12 rolls, perfectly sized to fit in a standard pickup truck bed for hassle-free transportation.
