RWS Roof and Wall Scanner. RWS Roof and Wall Scanner For non-destructive moisture evaluation of roofs, EIFS, foam insulation systems & other building envelope applications. Detects, locates and traces leaks in concrete flooring. To evaluate the extent of the moisture problem and help trace and pin-point its source.Tramex RWS Roof and Wall ScannerThe Tramex RWS is a multi-mode non-invasive impedance moisture scanner designed for the instant, precise and non-destructive evaluation of moisture conditions and leak tracing in the roofing and walls systems of the building envelope.MATERIAL:ROOF Non-Conductive Single Ply Roofing Built-Up Roofing Modified & Spray Foam Roofing SystemsWALL Exterior Insulation and Finishing Systems (EIFS)CONCRETE Concrete flooring and substrates.The RWS incorporates two of the best known Tramex moisture scanners, the Leak Seeker for Roofing and the Wet Wall Detector for EIFS to give all the benefits and features of both of these time-proven instruments.The Problems of Excess Moisture in the BuildingBy visual inspection, locating excess moisture and decay in or behind EIFS or Roofing Systems can be extremely difficult as normal evidence of this moisture and decay may not be visible on either side of the wall or roof. Excess moisture can be hidden and trapped in the substrate and within the thickness of the wall or roof construction. If these conditions are allowed to continue the moisture will increase, eventually leading to rot and decay and possible failure of the system and the structure. Also wet insulation loses its thermal value, resulting in unnecessary heat loss or gain and thermal movement in the structure. Early detection of wet areas and corrective remedial action makes good economic sense.PRODUCT DESIGNThe Roof & Wall Scanner detects and evaluates the moisture conditions within roofing and wall systems and other bu
