Proposals that show the windows you actually install.
Stop losing premium Marvin and Andersen Architectural projects to replacement franchises that pitch 1-day installs on commodity vinyl. Glewit ships premium window and door proposals, contracts, and warranty handovers from one source of truth — every Marvin Ultimate frame, Loewen sash, Emtek mortise lock, AAMA InstallationMasters-grade install detail, and historic-preservation specification on the page. Free trial. Window & Door catalog included.
They saw a 1-day-install ad. You're installing a $5,000 architectural window. The proposal can't tell them apart.
You hold the certifications a premium project should be paying for — Marvin Authorized and Architectural, Andersen Circle of Excellence, AAMA InstallationMasters — and you measure every opening in person, install to AAMA 2400-19, and register the warranties that depend on it. But the homeowner has seen the replacement-franchise ads — '1-day install,' a number that sounds too good — and they can't tell your $5,000 Marvin Architectural true-divided-lite from the franchise's $1,500 vinyl insert on paper. Your measurement discipline, your install cert, the fact that the warranty actually holds because you're authorized — all invisible. By the time you've assembled the proposal between site visits, they've anchored on the franchise's number and the product they think is 'the same Andersen.' The product was never the problem. The paperwork was.
Proposal → Contract → Handover
Project data flows forward — enter it once, render it three ways. Every field on the proposal carries through to the contract and the handover packet.
The actual product you install, priced per opening — every Marvin Signature Ultimate and Architectural window, the LaCantina folding glass wall, the Emtek and Rocky Mountain hardware, and the premium glazing from your spec, not a generic 'windows' line a commodity-vinyl replacement can match on price. Same home, three product tiers.

The §15 terms in writing — the field-measurement protocol (in-person, after demolition), the AAMA 2400-19 rough-opening tolerances, the AAMA InstallationMasters install methodology, the manufacturer warranty registration timing (Marvin within 60 days), and the historic-preservation contingency.
Open full document →
Manufacturer warranty registrations across all five categories — windows, entry & exterior doors, interior doors & millwork, premium hardware, and glazing — plus the AAMA InstallationMasters install certification and the NFRC ratings. The documented close-out that proves the warranties are registered and the install is the one they depend on.

Marvin, Andersen, Loewen — embedded automatically.
Glewit embeds the actual manufacturer spec sheets and NFRC rating labels in your proposal. The homeowner sees the Marvin Ultimate warranty terms, the Andersen E-Series data, and the Loewen all-wood spec exactly as the manufacturers publish them — so a premium architectural window can't be confused with a commodity vinyl insert. Update the catalog once; every future proposal pulls the current sheet.
