Why Crateworks
- Coordinated rollout across all units. One spec, one finish, one cert pathway. The unit count drives factory consolidation and the per-unit cost lands well below per-unit retail.
- Source-direct on the multifamily spec. No dealer margin compounded across hundreds of units.
- STC acoustic spec available without separate sourcing. Unit-to-exterior and corridor isolation specs handled in the same product line.
- Pricing locked from purchase order through delivery in writing. Holds through long multifamily build cycles where dealer-supplied product can re-price mid-project.
Common questions
- How does volume pricing work?
- Multifamily volumes start at 50 units. Pricing scales by total unit count and standardization (how many distinct window and door configurations across the project). High standardization with high unit count drives the largest per-unit cost reduction.
- What about acoustic requirements between units?
- Acoustic isolation between units is primarily a wall and floor assembly question, not a window spec question. Where the unit envelope itself needs acoustic spec (corner units adjacent to elevators, units facing busy streets), STC 40 to 48 windows are available on the same product line.
- Can you handle a phased rollout across multiple buildings?
- Yes. Phased delivery schedules align factory production with the construction calendar. Lock the spec at design development; deliveries phase against the install schedule with pricing held through the project term.
- What lead time should I plan for?
- Multifamily lead time runs 14 to 20 weeks from order to first delivery, depending on volume and configuration count. Confirm lead time at the spec engagement so it aligns with the construction schedule.
