Window Selection
Windows for the house are to be selected by you from a local BC supplier to meet the minimum thermal performance criteria of R-6.67 (U-0.15).
List the manufacturer and summarized the relevant information for your selected window, including U-value, SHGC, NAFS rating, and any other criteria you might find useful.
For the selected windows, you will need to evaluate the window frame design on the 9-point scale covered during the window class and Section 5.9 of the course textbook. To do this, draw a separate 1:1 scale sketch through the window sill profile and evaluate the following 9 criteria directly on the drawing (10 marks). Use your chosen window profile in the detailing of the assemblies.
1. Continuity of the water shedding surface (WSS)
2. Continuity of the water resistive barrier (WRB)
3. Vertical or sloped water shedding surface
4. Use of continuous compression gaskets for operable vents
5. Use of continuous compression gaskets or shimmed tape at glazing stops
6. Unobstructed drainage path within the window assembly, between the WSS and the WRB
7. Capillary break between the WSS and the WRB
8. Continuous air barrier
9. Durable materials at frame joints
Note: Make the assignment based on a supplier of windows from British Columbia
