Continuous Air Seal

NOTE: Shims may need to be cut back, so the interior air seal is

“continuous“ between the window frame and the rough opening.

Create a required continuous air seal on the interior by integrating the

rough opening and the window frame with low-expansion polyurethane

foam or backer rod and sealant. NOTE: If foam is used, a 1/2" - 1" depth

is prescribed. Backer rod can be used to control the depth.

Low-expansion foam

If applicable, remove any protective lm immediately

from all surfaces of the frame/sash and within six

months from any glass.

REMOVE PROTECTIVE FILM

After Installation

• Ensure weep holes/channels are clear of debris for proper water

drainage. DO NOT seal weep holes/channels.

• Install exterior wall surface per manufacturer’s guidelines.

• Leave an expansion/contraction gap of approximately 3/8" between the

window frame and nal exterior wall surface (siding, stucco, etc.).

• Protect recently installed units from damage from plaster, paint, etc.

• The head and seat board should be protected (e.g., roof, skirt) and

insulated with rigid foam.
