Design & Glazing - Care should be exercised to insure sufficient clearances in frame members to allow for thermal expansion and proper fit. Tempar-Glas® should never become load bearing. All design and glazing should be in accordance with the Glass Association of North America’s Glazing Manual.
Flatness - As is characteristic of the tempering (and heat-strengthening) process, a slight deviation from the normal flatness associated with annealed glass will be found. The amount of deviation depends upon glass thickness, length, width, and other factors. However, the overall bow and warpage will not exceed that which is allowed by the American Society for Testing and Materials (ASTM) specification number C1048-04, Table 2. In addition, a very slight surface wave may be caused by contact with the furnace rollers. This waviness can sometimes be detected when viewing reflected images on the glass surface from a distance.
Design Consideration - Design criteria such as structural integrity, strength, thermal movement, air infiltration, static pressure and other structural and performance considerations are the sole responsibility of design professionals such as structural engineers and/or architects。 Virginia Glass Products Corporation furnishes quotations for; and upon receipt of a written purchase order, glass and accessory hardware as requested by the customer。 Virginia Glass Products Corporation is not selling a prepackaged system。
