TitleSpecification(s)Objective(s)
3.1201.7a
Worker safety

All worker safety specifications will be in accordance with SWS 2.0100.3 Worker Safety

Ensure worker safety, especially in regard to fall protection considerations and contaminants found in demolition, such as asbestos, lead, polychlorinated biphenyls, etc.

3.1201.7b
Occupant safety

Occupant will be notified of changes or repairs to be made

An occupant safety plan will be prepared and implemented

Occupant will be shown how to properly operate the window system

Ensure occupant safety

3.1201.7c
Pre-inspection

Glazing systems will be inspected for air and water leakage, warping, stability, holes, proper hardware operation, proper operation, and security; if the items above cannot be repaired, the glazing systems will be recommended for replacement

Determine the scope of glazing system repair

3.1201.7d
Operable glazing system operation and fit

Operable glazing system will be adjusted or repaired to properly fit the jamb and allow for ease of operation (e.g., hardware adjustment and/or replacement)

Ensure proper operation of the operable glazing system

3.1201.7e
Fixed glazing system adjustment and seal

Fixed glazing system will be adjusted or repaired to properly fit the jamb

In the event the fixed glazing unit has shifted enough to allow light to leak around the perimeter frame, the glass will be properly repositioned in its frame/pocket

After repositioning/adjusting, the glass will be sealed to the frame

When sealing exterior frame components, internal water drainage systems within the glazing system will be maintained

When sealing exterior frame components, wall system water management components will be maintained (e.g., weep holes)

Ensure proper adjustment of glass (e.g., caulking used to seal a gap can compromise the integrity of the thermal pane seal)

Ensure an airtight and weathertight fixed glazing system

Ensure a durable and secure glazing system

Prevent water intrusion

3.1201.7f
Sealant selection

Sealants will be compatible with their intended surfaces and applied in accordance with manufacturer specifications

Selection will be durable, pest resistant, and have a weather-appropriate seal

Indoor sealants will be low volatile organic compound ( VOC VOC Volatile organic compound ) products that meet independent testing and verification protocols, such as Green Seal GS-36, "GREENGUARD Children and Schools," or comparable certifications

Fire resistance rated assemblies will be provided with sealants permitted by the authority having jurisdiction and adopted building code

Prevent intrusion of moisture and pests into the sealed assembly

Prevent exposing workers or occupants to excessive VOC VOC Volatile organic compound levels

Ensure sealant meets or exceeds the performance characteristics of the assembly and is compliant with local fire code requirements

3.1201.7g
Frame sealing

When the glazing system trim/frame leaks at wall, the glazing system trim/frame will be sealed to the exterior and/or interior side of the wall

When the glazing system components leak at the frame, areas of leakage will be sealed

When the existing window frame has penetrations due to old hardware, the abandoned penetrations will be sealed

When sealing exterior frame components, internal water drainage systems within the glazing system will be maintained

When sealing exterior frame components, wall system water management components will be maintained (e.g., weep holes)

Ensure the glazing system frame is airtight and watertight

Prevent water intrusion

3.1201.7h
Weather stripping

All weather stripping will be an effective air barrier Air barrier The separation between the interior and exterior environments of a building that slows air flow to the point that no smoke movement is visible at 50 pascals of pressure difference across the boundary

Durable weather stripping material will be sized to span irregularities in the glazing system, as well as seasonal variations

Where weather stripping fits into an existing track, replacement weather strip will be sized to fit the original track and to span irregularities

Weather stripping will be installed and mechanically fastened around all four sides of the glazing system

Mechanically installed weather stripping carrier will be sealed to surface

Operable glazing systems will be tested for ease of operation and airtightness after weather stripping is installed

Identify appropriate weather stripping materials to make an airtight and watertight seal while maintaining the operation of the glazing system

Ensure glazing system is airtight and allows for seasonal variation

Ensure operable glazing system operates properly after weather stripping is installed

3.1201.7i
Quality assurance

Glazing system will be adjusted to properly fit the jamb and allow for ease of operation and security

Glazing system will be tested for air leakage in accordance with ASTM ASTM ASTM International, www.astm.org E783-02 or ASTM ASTM ASTM International, www.astm.org E1186

Water management systems and enclosure drainage planes will be verified as maintained

Ensure proper operation of the glazing system and hardware

Prevent air leakage through assembly

Prevent water intrusion
