Markets

Built for the projects where the window decides.

GlasFëns is a specification-driven supplier. We work with developers, architects, general contractors and glazing contractors from the first energy model through procurement, shop drawings and delivery.

Multifamily

Punched-window packages for 10–50 unit buildings, the segment where whole-window U-value moves the energy model most. We track the Massachusetts LIHTC and market-rate pipeline and time procurement to the GC's schedule.

Passive house

Phius-registered and PHI projects across the Northeast. The F-Series is engineered for low whole-window U-values, minimal thermal bridging and airtightness, with narrow frames for higher glazing ratios and solar gain.

Prefab & modular

Consistent profiles, factory-friendly packaging and predictable lead times for modular and panelized builders nationwide.

Hurricane & coastal

The A-Series brings thermally broken, impact-rated aluminum to Florida and Gulf Coast projects, produced with our partner Superhouse.

Commercial & institutional

Hospitality, office and institutional buildings that need to meet demanding energy codes at commercial budgets.

Single-family

Custom homes and deep-energy retrofits where an architect wants the best glass available and a frame that will last as long as the house.

Massachusetts Specialized Energy Code: new multifamily buildings over 12,000 sq ft in the towns that have adopted the specialized code must meet passive-house-grade envelope performance. Vacuum-glass fiberglass windows are one of the few ways to get there without shrinking the windows. We have obtained code approval for vacuum-glass windows in New York City and Newton, MA using LBNL WINDOW calculations.
