Project Requirements & Specifications
The Bonneville Power Administration (BPA) has constructed a list of installation and specification requirements that must be followed to receive the window rebate. Both contractors and self-installers should use these requirements as a checklist when performing window installations. Proper installations and window specifications are verified before rebates are processed.
For installation requirements specific to nail fin, flush fin, and block frame window types, please refer to BPA’s Weatherization Specs and Best Practices Guide.
General Window Requirements
- Replacement windows must be certified and labeled for U-factor in accordance with the simulation, testing, and certification procedures of the National Fenestration Rating Council Incorporated (NFRC).
- Installers should always confirm that adhesives being used are designed and rated for exterior use and will work with both existing and new flashing and water-resistive barriers.
- Caulk and prime all exterior wood, including frame, sash, trim, stops and sills on all sides and ends.
- Support the bottom rail of a patio door within 1/2 inch of exterior edge of the frame. Any wood that touches the ground or concrete must be pressure-treated.
- Incorporate the replacement window and window opening into the home’s water-resistive barrier using proper flashing techniques for each specific window type.
- Hardware and fasteners must be aluminum, stainless steel, or another noncorrosive material.
- Seal the structural frame to the window, and seal surrounding gaps and cracks.
- Frame: Install caulk or low-expansion foam between window frame and rough opening. Install backer rod or non-expanding foam and caulk where gaps are greater than 3/8 inch.
- Exposed framing components: Caulk at exposed wood-to-wood framing cracks; remove sash weights, if applicable, and seal and insulate weight channels.
- Cover gaps of over 3/8 inch between the exterior siding and the window with solid trim material. Fill all exterior or interior voids over 3/8 inch in width or depth with window manufacturer-approved materials, such as non-expanding foam, backer rod, or similar product prior to caulking, if caulking will be applied.
- Verify that windows operate smoothly and safely.
Safety Glass and Emergency Egress
All windows must meet the following safety glazing and egress requirements. Use safety glazing in locations where the risk of breakage is high. Egress windows are windows with an opening
sash large enough for people to use as a fire escape. Safety glazing requirements apply to replacement windows, replacement patio doors, multi-glazing inserts and storm windows. Each pane of glass requiring safety glazing must bear the manufacturer’s permanent safety glazing label. This label of identification is etched or ceramic-fired on the glazing and clearly visible in one of the corners of the pane.
Please refer to state and local codes for required safety-glazing locations. Common locations for safety glazing include the following:
- Glazing in entry doors.
- Glazing in patio doors and French doors.
- Glazing in a fixed or operable panel that meets all of the following conditions:
- The exposed area of an individual pane is greater than 9 square feet.
- The bottom edge is less than 18 inches above the floor.
- The top edge is greater than 36 inches above the floor.
- One or more walking surfaces are within 36 inches horizontally of the glazing.
- Glazing in a fixed or operable panel adjacent to a door where the nearest vertical edge of the window is within a 24-inch arc of the door in a closed position and whose bottom edge is less than 60 inches above the floor or walking surface.
- Glazing in hot tubs, whirlpools, saunas, steam rooms, bathtubs, and showers, if the bottom edge of the glazing is less than 60 inches above the drain inlet.
Generally, when windows in bedrooms are replaced, egress windows should be recommended.
