Fenestration Energy Performance Testing Services

The CSA A440.2 certification program offered by QAI allows manufacturers to apply the QAI certification mark with thermal performance ratings to the evaluated product models and involves periodic inspection of production at the manufacturing facility to facilitate ongoing conformance of labelled products with the standards.  Computer software is used to create a model of the window or door with the glass options that are chosen.

For Canadian compliance, a physical test sample is not required to perform the thermal performance aspect of testing; however, a completed NAFS test report must be provided for each product type when submitting for Canadian ENERGY STAR approval (see NAFS physical testing section for more detail).

QAI also offers NFRC thermal performance testing for compliance with U.S. requirements, this includes thermal simulation, validation (hot box) testing and air leakage testing. Validation testing requires the physical testing of a sample window for each product line confirming the accuracy of the simulations.

NFRC LEAFF Methodology

NFRC Linear Energy Analysis For Fenestration (LEAFF) follows a procedure to capture glazing options by trendlines, allowing large catalogs of low-E combinations to be calculated and certified from their centre of glass values without direct modeling of every glass. Ask your QAI Project Manager if LEAFF modeling can reduce your cost and time over conventional modeling. QAI has several NFRC and LEAFF Certified Simulators with extensive industry experience throughout North America to support your Fenestration Energy program.
