Last week we submitted our 16ft wide x 9ft tall Sliding Patio Door for testing and received NAFS certification by Intertek Labs. Our door meets or exceeds the NAFS- 08 standard for Vancouver. Vinyltek has the big, big doors for the big, big views of the most beautiful place in the world. These tests are comprehensive, and tough. Many door makers can’t meet the standards required by the Province. Our superior materials and our craftsmen & craftswomen make a great, tested, high performance, ‘huge’ Patio Door.
