Hollow Metal Borrowed Lite Frames

Borrowed light describes an architectural design practice where natural or artificial illumination is transferred from an exterior wall or well-lit space into an adjacent interior room through glazed openings. Hollow metal borrowed lite frames hold the glass securely while providing necessary fire ratings and physical durability.

Hollow metal borrowed lite frame assemblies can be fabricated using steel thicknesses ranging from 16 gauge to 12 gauge. This range allows commercial builders and distributors to select appropriate durability levels for light commercial applications, high-traffic corridors, or heavy-duty industrial environments.

Yes, hollow metal borrowed lite frame assemblies can be supplied with UL fire-rated labels. These frames are manufactured in compliance with NAAMM and HMMA specifications, ensuring that commercial buildings fulfill critical life-safety and building code requirements for fire-rated wall assemblies.

Standard frame lead times range from five to seven business days. Expedited options may also be available depending on shop schedules and order parameters, supporting distributors and project managers who need to resolve door schedule misses without delaying job site progress.

Yes, these assemblies support both standard and custom profiles. They can be engineered to accept glazed panes or solid panels, allowing distributors and architects to configure multi-lite sidelite, transom, and window frame combinations tailored to unique commercial project specifications.

Deliveries are coordinated across the Eastern United States, covering areas from the Carolina coast to Detroit, the Ohio Valley, and Nashville. Dedicated fleet routes support reliable direct-to-job-site or distributor facility deliveries according to project timelines.
