IRSC offers field testing that follows laboratory test standards for newly installed fenestration units. Typically, this is done during the construction phase of a project. This testing provides a means for determining the performance of fenestration product(s) once installed (after water barrier and exterior accessories, but prior to interior finishes) into the building for quality assurance. IRSC offers both air and water performance testing, which is valuable for new construction, renovations and major repair projects.
Our calibrated Sprayrack® and air flow meter equipment is operated by our experienced field technicians who are proficient with American Architectural Manufacturers Association (AAMA) and North American Fenestration Standards/Specifications (NAFS) for curtain walls/storefronts, windows, doors and skylights. Testing is conducted in general accordance with the American Society for Testing and Materials (ASTM®) standards.
Water testing determines the resistance to water penetration through building assemblies for compliance with specified performance standards. It can also be used to determine the resistance to infiltration through the joints between the building assemblies within adjacent construction.
Air testing is intended to measure the air leakage associated with the fenestration assembly and not the leakage through openings between the assemblies and adjacent construction. IRSC can determine the amount of air leakage of the fenestration unit(s).
Testing fenestration(s) and adjacent construction after initial installation and prior to interior finishes is highly recommended as it is generally easier to check the interior surfaces of the assemblies and to identify issues.
Types of Water/Air Entry Performance Testing:
- Building Envelopes
- Curtain Walls / Storefronts
Benefit of Non-destructive Water/Air Performance Testing:
The benefit of testing when assemblies are initially installed is that errors in fabrication or installation are readily discovered and corrections made before construction is final. The expense and potential disruption of corrective work after occupancy is considerably higher.
