TREMCO CONSTRUCTION PRODUCTS GROUP INFRARED INSPECTIONS ARE PERFORMED BY CERTIFIED (EXPERIENCED) INFRARED THERMOGRAPHERS UTILIZING STATE-OF-THE-ART EQUIPMENT. ALL WORK CONFORMS WITH CURRENT INDUSTRY BEST PRACTICES, AND IS PERFORMED IN ACCORDANCE WITH STANDARDS PUBLISHED BY

ASTM INTERNATIONAL AND INFRASPECTION INSTITUTE.

How An Infrared Survey Works:

Wet roof insulation absorbs more solar energy from the sun during the day than dry insulation. As the sun sets, the nighttime cools the roof surface. Wet insulation retains more solar energy than dry insulation. These temperature differences are detected by the infrared camera. All full service scans are performed using a mid-wave IR camera with a 2.5 - 5.6 spectral range. Suspected wet insulation is verified through core cuts and/or a Roof Moisture Meter.

Core cuts are taken to establish acceptable levels of moisture. Confirmed wet areas are marked out on the roof surface with paint.

How A Moisture Meter Works:

During the daytime, readings are taken and recorded in random locations and at wet areas found by the infrared camera.

Fast neutrons are emitted from the source in the Roof Moisture Meter into the roof system. The presence of hydrogen in the roof system slows the neutrons. These slowed neutrons as well as the fast neutrons are detected by the Roof Moisture Meter. A reading is displayed in the digital readout and gets recorded.

Core cuts are taken to determine a baseline for dry roof materials. Wet areas of insulation are marked on the roof surface with paint.
