Ancestral® Window
Performance
All our windows have to go through a rigorous process of testing and approvals. To pass the highest performance standards, Belisle’s products are tested, both in our R&D department and at an independent certified testing laboratory, under extreme weather simulations. All our products are rigorously tested for air and water infiltration as well as structural and energy performance.
Because we at Belisle are committed to receiving the best ratings, we are proud of the results from the many testing parties to which we submit our products - NFRC, Energy Star, or AAMA.
Results obtained for the product CSA A440 as recognized by the Canadian Normalisation Association.
