Why Crateworks
- Source-direct on aluminum profiles slim enough to match the original wood sash sightline. Casement and double-hung carry NFRC ratings for permit-required restoration work.
- Arc-top configurations cover half-round, segmental, eyebrow, and full-arch heads — the radius variants period elevations need.
- RAL color match through AAMA 2605 PVDF coating with a 20-year finish warranty. The frame holds the period color without repainting.
- Decorative muntins / true-divided lights specified per opening. Cert envelope covers grille configurations on the base unit.
Common questions
- Can aluminum match a historic wood window profile?
- Yes for the sightline and the proportion. A thermally-broken aluminum casement with a deep sill profile reads close to the original wood sash at glass-to-glass dimension. Where exact reproduction of carved or moulded wood detailing is required, the project routes to a hybrid spec; tell us the elevation drawing and we will confirm match feasibility.
- Are these windows code-compliant for new construction?
- Yes on the certified configurations (casement, tilt-turn, fixed, awning, arc-top, double-hung, single-hung). NFRC ratings cover IECC energy compliance in the states that require it. CSA A440-22 is on file for Canadian historic projects.
- Can you do true-divided lights?
- Yes. True-divided lights and simulated-divided-light grilles are both available. Grille configurations carry through the cert envelope on the base unit; specify the grille pattern at quote.
- What about RAL color match?
- Frame colors are specified by RAL number — the same way an architect calls them out on a drawing. The AAMA 2605 PVDF finish holds color through long-term UV exposure with a 20-year coating warranty.
