Tremboard AC

Semi-Rigid, Asphaltic Roof Protection Board

TremBoard AC is a multi-ply, semi-rigid, asphaltic board designed for use as a protection layer between the insulation and membrane of various Tremco low-slope roofing systems.  Being semi-rigid, it can compensate for minor deck or insulation irregularities. TremBoard AC can be mechanically fastened, adhered, or mopped using Thermastic adhesive or other hot asphalt.


The TremBoard AC protection board is composed of a mineral-fortified asphaltic core molded between two asphalt-saturated fiberglass reinforcement mats.  TremBoard AC is available in thicknesses of 1/8" and 1/4".
