Spec sheets

Pella® 2026 Architectural Design Manual — Impervia® Double-Hung Windows — Pella Corporation · PDF
26 pages. Size Tables run from page 11 (vent equal), through vent cottage and vent contemporary, to fixed transoms, and every unit elevation on all four is a rectangle. Free and ungated. Pella indexes every one of these at media.pella.com/professional/adm/Misc/ADM-Links.pdf, which is the best window route the census found and the reason this category's real deliverable is the document library rather than the figure.

Installation instructions

Impervia — Installation Details — Pella Corporation · PDF

Specification notes

Tempered glass is an available option, but the cited page does not state the tempered-pane count for an order. This record therefore matches only the documented multilayered-glazing path.
