Using a Thermal Imaging Camera to Locate Moisture in a Commercial Flat Roof
Thermal imaging cameras can create detailed maps of commercial low-slope roofs, showing where excess moisture is trapped, where the source of a leak may be, or where there is soaked or compromised insulation. Roofing professionals scan the roof, taking images to compile into a composite map, or they take an aerial image of the whole…
An Introduction to Thermal Bridging
A thermal bridge is a pathway that heat uses to get in or out of a building, bypassing the insulation layer. For example, your roof may be well insulated, but a metal plumbing vent that passes through the roof and its insulation can carry heat in or out of the building. Heat moves not just…

What is a Roofing Base Sheet?
A roofing base sheet is the bottom waterproofing layer on a multilayer roofing membrane system. It is made of fiberglass or reinforced polyester, or composite reinforcement and is saturated/coated with modified bitumen asphalt. This is asphalt enhanced with plastic or rubber polymer. Base sheets are surfaced with heat-weldable film, sand or a release film depending…
