Panes manufactures its own windows and installs them across the Des Moines metro from its showroom at 4405 SE Beisser Drive, Grimes, IA 50111. Book a free in-home measure: a specialist measures every opening, explains what needs replacing, and leaves an itemized written quote for supply only or fully installed work. No deposit and no credit card are required.
Bring a written window quote from an approved premium competitor, dated within the last 30 days. Panes prices the same window scope from its published price list, and if the competitor total is lower, Panes beats that total by 5% in writing. Line items are not matched separately, and doors are not eligible.
Panes builds its windows in its own plant, installs them with its own crews, and services what it builds. There is no supplier, installer, and warranty department to negotiate between — the company that made the window is the company that stands behind it.
Iowa sits in the NFRC Northern Zone, which asks for a U-Factor of 0.27 or lower. Panes windows are built triple-pane as standard with Cardinal LoE3-366 and i89 coatings plus argon fill, reaching an NFRC U-Factor of 0.130. Frames are multi-chamber heavy-duty vinyl with fusion-welded corners, hardware is Roto of Germany, and units are rated NAFS-22 CW-PG60.
Panes windows carry a limited lifetime warranty that is non-prorated and transferable once to a new homeowner. Vinyl frames, welded sashes, and weather-stripping are covered for life; insulated glass units against seal failure and factory-applied exterior finishes for 20 years; operating hardware and insect screens for 10 years. Labour and re-installation costs, glass breakage, and damage from improper installation on supply-only orders are not covered. Full terms are published at /warranty.
