Woodgrain Exterior Transoms - 1 Lite: Nine Wood Species for Perfect Entry Door Matching

Available with both clear single-glazed or insulated Low-E glass for enhanced energy efficiency, these transoms solve the architectural height problem that standard 6’8” doors create. Allows natural light into entry or patio doorways. Available in 9 wood species for perfect matching with Woodgrain entry door systems.

Worth buying for custom builders who need precise wood species matching with existing door systems. The nine species options and custom sizing flexibility eliminate the wait times and upcharges of custom millwork shops.

Skip them if you’re looking for a maintenance-free solution. Regular refinishing (every 1-3 years) is mandatory to maintain structural integrity.

Custom Sizing That Actually Fits Your Opening

Standard widths from 2’0” to 3’6” and standard heights from 10” to 18” cover most residential applications. But here’s what matters: the 4” width increments and 2” height increments mean you’re not stuck with awkward gaps or forced to order full custom.

Specification	Range	Increments
Width	2’0” to 3’6”	4”
Height	10” to 18”	2”
Thickness	1-3/8” or 1-3/4”	—
Glass Options	Single Glazed (1-3/8”) or Insulated Low-E (1-3/4”)	—

The 1-3/4” thickness matches standard Woodgrain exterior doors (700s, 800s, and high-end collections). No shimming. No custom jamb work. Just proper fit.

Rough opening: Width of the transom unit plus 1/2”, and height of the transom unit plus 1/2”. Standard framing math that any competent carpenter knows.

Nine Species Options Beat Custom Shop Lead Times

Available in 9 wood species for perfect matching with Woodgrain entry door systems. Here’s the full lineup:

• Ponderosa Pine (PON)
• Radiata Pine (RAD)
• Knotty Pine (KPN)
• Primed (PRM)
• Knotty Alder (KAL)
• Douglas Fir (FIR)
• Rustic Hickory (RHK)
• Mahogany (MHG)
• Walnut (WAL)

Commonly praised for the natural beauty and wide species selection. The real advantage? Match your existing Woodgrain door perfectly without waiting 8-12 weeks for a custom millwork shop to match grain patterns.

Moisture-resistant, no expansion or contraction, providing superior dimensional stability. The MDO (Medium Density Overlay) flat panel core won’t warp like solid wood transoms. Occasional reports of warping if not sealed properly per warranty requirements — but that’s installer error, not product failure.

Energy Performance and Montana Reality

Available with both clear single-glazed or insulated Low-E glass for enhanced energy efficiency. In Montana’s temperature extremes, the Low-E option isn’t optional — it’s necessary. The 1-3/8” models with single glazing belong in temperate climates, not here.

Crafted from premium unfinished mahogany over a solid engineered wood core, it features a 1-3/4” thickness with clear, insulated tempered glass (1/2” thick) for safety and energy efficiency.

Fiberglass alternatives offer lower maintenance and higher rot resistance but lack the authentic grain, feel, and staining depth of Woodgrain’s real wood species. True. But fiberglass doesn’t need refinishing every 1-3 years either. Steel transoms are more economical and durable against physical impact but offer poor aesthetic appeal and high-end feel compared to solid or engineered wood.

Installation and Warranty Requirements

1-Year Limited Warranty from the date of manufacture. All six sides (top, bottom, edges, and faces) must be sealed within 15 days of installation. Requires proper overhang protection (typically 1/2 the door unit height) to prevent weather damage. Regular refinishing (every 1-3 years) is mandatory to maintain structural integrity. Warping coverage only applies if the deviation exceeds 1/4 inch.

The 15-day sealing requirement isn’t negotiable. Must seal all six surfaces (all edges and faces) immediately upon delivery or within 15 days. Miss that window, void your warranty.

Exterior grade stain or paint required; avoid dark colors in direct sunlight to prevent heat absorption and warping. Dark stains on south-facing entries are asking for trouble. The MDO core helps, but physics still applies.

Maintenance (sealing and refinishing) is noted as the primary trade-off for the aesthetic beauty of natural wood. That’s the deal with real wood — it looks better but demands attention.

Who Should Buy These Transoms

Best fit for:

• Custom home builders matching specific Woodgrain door collections
• Remodelers extending existing entries without full door replacement
• Projects where authentic wood grain matters more than maintenance

Wrong choice for:

• Rental properties or low-maintenance applications
• Extreme weather exposure without adequate overhang protection
• Budget projects where the refinishing schedule won’t be followed

The nine species options and sizing flexibility make these the go-to transom for matching existing Woodgrain systems. The 1-3 year refinishing requirement is real — budget for it or choose something else.

FAQ

What’s the actual rough opening needed for these transoms?

Width of the transom unit plus 1/2”, and height of the transom unit plus 1/2”. Standard carpentry math — nothing special required.

How often do these really need refinishing in Montana?

Every 1-3 years. With Montana’s UV exposure, plan on the shorter end of that range for south-facing installations.

Is the single-glazed version adequate for Montana installations?

Technically yes, but why? The insulated Low-E option is only available in the 1-3/4” thickness. In Montana’s climate, the energy savings justify the upgrade.

What happens to the warranty if the six surfaces aren’t sealed within 15 days?

Your warranty becomes worthless. All six sides must be sealed within 15 days of installation or coverage is void.

Which species holds up best in Montana weather?

All species require the same refinishing schedule of every 1-3 years regardless of wood type. No single species outperforms others in weather resistance.
