In-House Building Performance Testing
Conley Group offers a variety of building envelope performance testing services. Below are some of the tests we offer in-house, which helps keep costs within project budget.
AAMA 501.2 Field Water Spray Testing
Nozzle water testing consists of applying water using a handheld spray assembly employing a Type B2 #6.030 nozzle, pressure gauge, control valve, and a 3/4″ garden hose. The water flow to the nozzl e is adjusted to produce 30 psi at the nozzle. Water will be directed at the joint under test, perpendicular to the face of the specimen. The nozzle will be moved slowly back and forth above the joint, at a distance of 1′ 0″, for a period of five minutes for each 5′ 0″ of joint. An observer on the inside will check for water leakage.
ATSM E 514 Water Penetration and Leakage Through Masonry Testing
This test procedure and set-up is similar to that of ASTM C 1601. The same air and water tight test chamber is utilized, and a differential air pressure is applied across the specimen while simultaneously allowing water to flow over the face of the specimen. This test measures the amount of water that penetrates through the masonry wall.
ATSM C1601 Water Penetration of Masonry Wall Surfaces Testing
This test method is used to determine the water penetration quantitatively through a masonry wall surface. An air and water tight test chamber is installed on the exterior of the masonry wall. A water spray pipe is located at the top of the chamber that creates a flow of water down over the masonry wallsurface while simultaneously maintaining a differential air pressure across the specimen. The water is collected in the bottom of the chamber and circulated back through the system. The amount of water is measured at specified time intervals. At the completion of testing, the amount of water lost is the amount of water that has been absorbed through the masonry wall surface.
ATSM E1105 Water Penetration of Installed Exterior Windows, Skylights, Doors, Curtain Walls Testing
Water penetration testing consists of utilizing a test chamber located on the interior or exterior side of the specimen and installing a spray rack system at the exterior of the specimen. Air will be evacuated/supplied from/to the chamber to create the required pressure differential, while simultaneously applying water onto the exterior surface of the wall at a rate of 5 gallons of water per hour per square foot.
ATSM E783 Air Leakage Through Installed Exterior Windows and Doors Testing
Utilizing a chamber on the interior or exterior of the specimen, the rate of air leakage through the fenestration assemblies is determined at the project specified pressure differential induced across the assemblies. The air leakage rates determined are compared against the acceptable rates identified for the project
ATSM E2359 Field Pull Testing of an In-Place Exterior Insulation and Finish System Clad Wall Assembly
A 1″ thick, 24″ square bonding panel will be adhered to the EIFS using adhesive expanding foam. The test module hardware with force gage is mounted in-line in a manner to measure the force loads. Testi ng typically continues by increasing the force incrementally until the desired pressure or failure is reached.
ATSM C1193 Joint Sealants Testing
A portion of the cured sealant will be cut down both sides of the joint approximately three inches. The sealant is then pulled at 90 degrees. The sealant should tear cohesively within itself or elongate to a manufacturer’s specified extension value.
ATSM D4541 Pull-Off Strength of Coatings Using Portable Adhesion Testers
Pull testing will be performed by securing a loading fixture normal to the surface of the coating with an adhesive. A testing apparatus is attached to the loading fixture and aligned to apply tension force normal to the surface. The force applied to the loading fixture will be gradually increased and monitored until either a plug of the material is detached or a specified value is reached. The load values will be compared to the manufacturer’s values or values within the project specifications.
ATSM D5957 Flood Testing of Horizontal Waterproofing Installations
For investigative or quality assurance testing of horizontal waterproofing, we will performflood testing. Either the entire area can be tested by plugging all drains, or sections of the roof can be tested by constructing containment assemblies. Water is supplied to the test area until the specified water depth is achieved. The underside of the specimen is inspected for water leakage throughout testing
ATSM C1153 Location of Wet Insulation in Roofing Systems using Infrared Imaging
The infrared roof survey is best conducted shortly after sunset when the surface temperature of the roof drops quickly. Areas containing water within the roof system/insulation are cooled slower due to water having a higher specific heat capacity than rubber roof membranes and most building products. Thermal anomalies are found using a FLIR Systems B20 thermal imaging camera. Typically, these areas are marked on the roof surface for future repair or evaluation.
ATSM C1060 Thermographic Inspection of Insulation Installations
Using a FLIR Systems B20 thermal imaging camera, insulation within envelope cavities can be inspected for thermal anomalies.
ATSM E1186 Air Leakage Site Detection in Building Envelopes and Air Barrier Systems
- An interior-exterior temperature difference of approximately 20ºF is needed for the IR scan.
Indoor or outdoor air is moved through the building envelope by either pressurizing or depressurizing the building. Due to the indoor-outdoor temperature difference, local surface areas of the components exhibiting high air infiltration/exfiltration rates will be determined from the infrared pattern.
