Plastic Window Shims and Door Shims

plastic window shims

Solid plastic shims’ most common use is to easily align, level, and fasten in place door and window frames, including alignment for louver systems, skylights, and sloped glazing systems.

For entrance, storefront, and curtain wall systems, plastic door shims and window shims are used to align members or panels, vertically or horizontally, as well as to separate glass panels, permanently or temporarily.

When used for blast-resistant doors and windows, permanent plastic window shims and door shims may be required for extra resilience and can be special-ordered in fire-rated materials.
