Woodgrain 1 Lite Exterior Transom (FIR)

The Woodgrain 1 Lite Exterior Transom delivers custom overhead lighting with 24 glass options and broad door compatibility. Available decorative styles range from Clear to Frosted to Baroque, giving contractors flexibility to match any architectural style while meeting privacy requirements. Built from Douglas Fir with straight, vertical grain and high strength-to-weight ratio, this transom handles Montana’s freeze-thaw cycles better than pine alternatives.

Glass Customization and Performance

Twenty-four glass styles transform this basic transom into a design tool. Standard options include single-glazed tempered glass, with insulated Low-E glass available only on 1-3/4 inch thickness. The decorative options read like a glass catalog: Artique, Bamboo, Beveled, Charcoal Sticks, Cotsworld, Cross Reed, Delta Frost, Double Glue Chip, Glue Chip, Heavy Water, Mirror, Narrow Reed, Obscure, Rain, Ribbed, Seedy, Sycamore, Taffeta, V-Grooved, Water Drop, and White Laminated.

All glass is tempered safety glass for exterior applications. That Low-E option on the thicker units matters — Montana energy codes keep tightening, and that extra insulation value helps hit compliance numbers without redesigning the entire entry system.

Applications include residential front entryways to increase the perceived height of the door system and patio or side-entry doors to allow light while maintaining privacy using obscure glass. The obscure glass options solve the classic problem of wanting natural light without giving neighbors a view into your mudroom.

Material Specs and Installation Requirements

Douglas Fir earns its place in exterior applications. Douglas Fir is more durable and rot-resistant than species like Pine, though it may be more expensive. That rot resistance translates to real longevity in Montana’s wet-spring, dry-summer cycle.

Thickness options include 1-3/8 inch and 1-3/4 inch, with standard heights matching door openings at 6’8”, 7’0”, and 8’0”, and standard widths from 1’6” to 3’6”. Custom widths and heights available to match door opening requirements — crucial for those non-standard mountain home openings.

Installation demands attention to moisture management. Seal all cut surfaces and ends with a quality sealer immediately after fitting and before hanging. Allow adequate clearance for wood swelling in damp weather. Ensure the transom is properly flashed and integrated into the door frame assembly to prevent water infiltration. Skip that immediate sealing step, and warranty is void if the product is not properly sealed on all sides immediately after fitting or if installed without adequate overhead protection.

Compatibility and Warranty Coverage

Compatible door series include PON, RAD, KPN, PRM, KAL1, FIR, and MHG1. That’s eight different Woodgrain door lines this transom works with — flexibility that matters when matching existing installations or coordinating with other openings.

Warranty splits between components: Standard 1-year limited warranty for manufacturing defects (typical for Woodgrain exterior wood doors) covers the wood itself. Glass seal gets 10-year limited warranty against moisture between glass panes for insulated units. Standard protection, nothing exceptional.

ENERGY STAR partner status and Low-E insulated glass options may meet regional energy codes, while Woodgrain generally utilizes SFI (Sustainable Forestry Initiative) certified wood sources.

The 1-Lite provides a cleaner, unobstructed view and is easier to clean compared to 2-10 lite options. Single pane means no grids to collect dirt, no multiple glass surfaces to squeegee. For contractors tired of callbacks about dirty divided lites, the simplicity pays off.

FAQs

Can I get insulated glass in this transom?

Insulated Low-E glass is available only on 1-3/4 inch thickness. The thinner 1-3/8 inch units come with single-glazed tempered glass only.

What door systems work with this transom?

Compatible with PON, RAD, KPN, PRM, KAL1, FIR, and MHG1 door series. Compatible with standard exterior door frames and headers designed for transom inclusion.

What happens if I don’t seal the wood immediately?
