Oak-woodgrain fiberglass double entry doors with leaded decorative glass and matching sidelites in a Craftsman-style hall

Trinity Glass International

Fiberglass doors made to look like wood and built to last

Trinity Glass International makes Feather River Doors and Signamark entry door systems for homes across the United States.

How we build our doors

Strength. Our patented molded designs build the glass frame into the door instead of cutting an opening for it, for structural integrity that stands up to the hurricane zones of Florida and Texas.

The look of wood. Detailed grain patterns of oak, mahogany and teak, with a sill, lite frame and glass designed to match a crafted wooden door.

Less waste. Molding doors to their glass openings, and using recycled materials for some components, cuts the waste of making a door by as much as 54%.

Energy efficiency. Polyurethane foam cores, triple-pane decorative glass and low-E clear glass. Many of our doors are ENERGY STAR certified.
