Multifamily or custom work

Fit
Who it is not for
BT99 is not the right path for every job.
- Vinyl packages. We do not sell vinyl.
- One-off DIY or a single opening with no drawings.
- Jobs that need glass in a few weeks. Read the Marvin and Pella comparison for the factory-direct schedule trade.
- Anyone who needs a local showroom.
Important: The signed Smart Offer controls scope, schedule, and price.
Operations, specifications, and price
- Operations we already publish: casement, fixed, awning, tilt-turn, horizontal slider, sliding glass, lift-slide, bi-fold, and swing glass where the catalog lists them. Final configuration is on the Smart Offer and approved shop drawings.
- Specs we will not invent: U-factor, SHGC, air infiltration, design pressure, NFRC IDs, Energy Star model IDs, thermal-break width, factory name, and city of manufacture are project-specific. Confirm them on drawings and the written offer.
- Price: indicative starting bands live on the catalog. Those are not a firm quote. The signed Smart Offer controls.
