Part 3EXECUTION

3.1WINDOW INSTALLATION

.1Install in accordance with CSA-A440.

.2Arrange components to prevent abrupt variation in colour.

.3Install shims between windows and building frame at each installation screw location. Shim and fasten windows in accordance with manufacturer’s recommendations and CAN/CSA A440.4.

.4

3.2CAULKING

.1Seal joints between windows and window sills with sealant. Caulk between sill upstand and window-frame. Caulk butt joints in continuous sills.

.2Apply sealant in accordance with Section 07 92 00 - Joint Sealants. Conceal sealant within window units except where exposed use is permitted by Owner’s Representative.

3.3TESTING

Note (size of project shown determines the extent of testing) Applied to projects with over 100 windows.

.1Air leakage testing as directed by Owner’s Representative and paid for by Contractor, will be performed by professional testing agency for three locations selected at random for window/wall assembly.

.2Window/wall assembly will include foundations, steel stud structure, gypsum sheathing and air barrier with on 1500 x 1500 window installed and sealed in place. (Omit spandrel panel for this exercise). Construct a test chamber on the exterior, from approximately 3100 high x approximately 3000 wide, sealed to foundation wall and face of air barrier on gypsum board. Provide mechanical anchorage to resist air pressure. Use a fan mounted in a door to achieve negative and positive pressures of 75 Pa. Use a smoke pencil to test for leaks. Total air leakage shall be less than 0.25 L/sec. for the tested assembly after accounting for leakage in the test chamber.

.3Testing will be witnessed by Owner’s Representative and test reports will be signed by Tester, Site Representative and Contractor.

.4Inform Owner’s Representative two (2) working days prior to required testing.
