ASHRAE documents governing energy efficiency and requirements for the components of building envelope design including fenestrations and glazing.

Specify glass thickness in Section 08 81 00

SECTION 08 53 00 Page 13

GLAZING. Inside glazing is preferred, especially for windows above first floor and other locations where access is difficult. Windows designed for inside glazing may not be available in double-hung type. Check manufacturer's literature. Where project requires insulating glass, show sash members, glazing beads, and hardware of sufficient size and weight to receive and support glass of specified thickness. Allow sufficient space between each side of insulating glass and frame for glazing compound or glazing gaskets and expansion as well as sufficient space between edges of glass and frame.

Drawings must clearly indicate method for securing insulating glass in place. Specify windows which will require glazing beads if they are indicated as such; specify vinyl, EPDM or silicone rubber gaskets in Section 08 81 00 GLAZING.

3.2 ADJUSTING

After installation of windows and completion of glazing and field painting, adjust ventilators and hardware to operate smoothly and to provide

SECTION 08 53 00 Page 16

weathertight sealing when ventilators are closed and locked. Lubricate hardware and operating parts as necessary. Verify products are properly installed, connected, and adjusted.

3.3 CLEANING

Clean interior and exterior surfaces of window units of mortar, plaster, paint spattering spots, and other foreign matter to present a neat appearance, to prevent fouling of weathering surfaces and weatherstripping, and to prevent interference with operation of hardware.
