Andersen Perma-Shield 1971–1992: meeting-stile seal

Quick answer. The Andersen Perma-Shield gliding window made from 1971–1992 uses weatherstrip at both the sashes and the frame. At the two sash edges that meet when the window is closed and locked, Andersen calls the sash component the meeting-stile weatherstrip. The frame seal is a separate item and its original replacement is described as no longer available. ¹²³

Check the location before asking for a legacy part

Andersen describes the operating and stationary meeting-stile replacement as white and ordered for the size of the particular window unit. ⁴ The color in a current catalog is not enough to date or size a previously installed strip, and does not convert the unavailable frame part into a meeting-stile part.

Preserve a usable evidence record

1. Confirm the Perma-Shield gliding window, and retain documentary evidence supporting its 1971–1992 manufacture period before using this article. ¹
2. Photograph the window both closed and locked and, when safe, sufficiently open to show the opposing sash meeting edges. Those edges are the source-defined meeting-stile contact. ²
3. Take separate pictures of the sash component and the frame component. Write sash/operating, sash/stationary, or frame, not just weatherstrip.
4. Capture the unit-size identifier and the existing fastening evidence. Andersen specifies size-based ordering and vinyl-to-vinyl adhesive for its replacement meeting-stile weatherstrip. ⁴⁵
5. If the issue belongs to the frame strip, record original unavailable per Andersen article and avoid presenting a local hardware-store substitute as verified. The manufacturer only mentions a possible similar locally sourced option. ³

Decision outcomes

Meeting-stile location and unit size established: consult the manufacturer for the correctly scoped part and any applicable service procedure. Frame strip identified: this is a separate availability problem; any candidate replacement requires independent geometry, attachment and safety validation. Period not confirmed: do not map modern glider weatherstrip parts onto an older unit based on white color or appearance.

The manufacturer page also gives a specific adhesive-based installation path. This article is not a license to use random solvents or adhesives, lift an unsupported sash, or infer a drop-in substitute for the discontinued frame material. ⁵ Keep the order request tied to photos, actual location and period evidence, and follow the original product's safety and service instructions.
