SINGLE-PLY 1

The single-ply family of roof membranes is composed of thermoplastic and thermoset products. Single-ply sheets are factory-fabricated and installed in a single thickness. Single-ply membranes are relatively easy to install on steep or complex roof slopes. In comparison to BUR or MB membranes, they are also very lightweight (except for ballasted systems). However, because there is only one layer of waterproofing, they do not offer the reliability of multiple layers.

There are six primary methods for securing single-ply roofing systems to the roof deck or other substrate:

۱٫ Fully Adhered: The membrane is adhered in a continuous layer of adhesive, preferably to a insulation cover board. Fully adhered roof systems typically have the highest wind uplift resistance and physical performance and are typically considered the highest performing method of installation for single ply roofs.
