Testing and Analysis Services

In-Situ Testing

In the field, BET&R's in-situ analysis and diagnostic testing services include; moisture analysis including electronic moisture meter, Vaisala, calcium chloride, and numerous other testing services. BET&R also conducts cladding and fenestration pressurized water testing services following ASTM- and some AAMA- standard protocols for window, door, and skylight water testing. Other types of testing BET&R conducts as part of moisture intrusion investigations and building envelope evaluations include RILEM testing, electrical resistance and electrical capacitance testing, and infrared thermography. BET&R can accommodate and provide a wide variety of ASTM compliant testing services.

Infrared Thermography

Infrared thermography is a powerful, non-invasive tool for surveying the underlying conditions of a building’s assembly, components, and building envelope systems. Because moisture has a marked impact on the thermal characteristics of many building materials, variations in the thermal signature can be used to efficiently identify potential areas of water intrusion and water retention within the building envelope. BET&R’s team of Certified Infrared Thermographers and building envelope experts are trained and experienced in using this advanced technology to detect anomalies in the heat signature of the building envelope, and to diagnose underlying and contributive causes of moisture related issues.

Air-Leakage and Air Barrier Testing

BET&R utilizes the Retrotec Q4E Blower Door System including the 3300-series fan and DM-2 Digital Manometer and performs air-leakage testing per: ASTM E779 Standard Test Method for Determining Air Leakage Rate by Fan Pressurization. ASTM E2357 Standard Test Method for Determining Air Leakage of Air Barrier Assemblies, and ASTM E1827 Standard Test Methods for Determining Airtightness of Buildings Using an Orifice Blower Door. Please note that energy codes in many jurisdictions are now requiring new buildings be tested for air leakage and for the exterior wall and roof assemblies to include a continuous air barrier. Testing for assurance that the required criteria are being met is also now written into the new energy codes. BET&R is capable, trained, qualified and has the equipment for the types of testing required. The Washington Energy Code, effective date January 1st 2011, requires that the whole building be tested for air leakage per ASTM E779, or similar approved test. The Seattle Energy Code, effective date January 1st 2011, states, "air leakage control shall be considered acceptable when tested to have an air leakage less than 0.00030 Specific Leakage Area (SLA) when tested with a blower door at a pressure of 50 Pascals (0.2 inch w.g.)." BET&R utilized the Retrotec Q4E Blower Door System including the 3300-series fan and DM-2 Digital Manometer and can perform testing per ASTM E779, and also per: ASTM E2357 Standard Test Method for Determining Air Leakage of Air Barrier Assemblies, and ASTM E1827 Standard Test Methods for Determining Airtightness of Buildings Using an Orifice Blower Door. If our testing indicates that air-leakage exceeds the required maximums, BET&R locates and identifies the problem/deficiency utilizing one or more of the many diagnostic tools at our disposal, including infrared thermography used in combination with building pressurization, and then provides expert technical consulting for mitigating the air leaks efficiently and effectively.
