Specialty windows go wrong at the trim, not the glass. We finish both.
Most window companies can order a circle or arch window. Far fewer can finish the surround, match the casing profile, and paint it so it reads as part of the original architecture. That’s where specialty window installations fail. Woodruff’s in-house crews handle fabrication, installation, and every inch of the finished surround, and have since 1982.
Custom Shape Fabrication & Fit
Specialty windows are built to the exact opening dimensions, not adjusted to a stock size after the fact. We confirm measurements, account for the rough opening tolerances, and verify the fit before any trim work begins. A shape that doesn’t fit squarely never looks right, no matter how good the finish is.
In-House Crews. Never Subcontracted.
The crew that installs your specialty window is the same crew that fits the casing, matches the exterior trim profile, and does the final paint touchup. One team, full accountability, no handoffs between contractors who’ve never seen the job.
Trim, Casing & Paint-Matched Surround
Interior casing is custom-fitted to the shape of the unit and paint-matched to your existing woodwork. Exterior trim is built to match the profile of the windows it neighbors. The finished result looks like the architect drew it that way on day one.
Explore Geometric & Specialty Window Installation
Everything worth knowing before you commit: the shapes we install, how specialty windows perform on energy and glass, and the hardware and glazing details that make a fixed unit last for decades.
Fixed by design. Built to the opening. Finished to the house.
Arched & Radius Windows
Full arches, half rounds, and eyebrow arches are among the most requested specialty shapes in North Texas, especially above entry doors and in foyer transoms. The radius is fabricated to the exact opening, and the interior surround is built to follow the curve cleanly all the way to the wall.
Circle, Oval & Octagon Windows
Round and geometric shapes are common accent windows in gable ends, stairwells, and as focal points on front elevations in neighborhoods like Tucker Hill and Stonebridge Ranch. Each is fixed glazing, sealed at the frame, and finished with a custom interior and exterior surround built to match the existing trim profile.
Trapezoids, Triangles & Custom Angles
Rake walls and vaulted rooflines often create openings that don’t conform to any standard shape. We fabricate to those angles directly from field measurements. If the opening exists and the structure is sound, we can put glass in it.
Fixed glass performs well. The frame and seal determine whether it stays that way.
Cardinal Lodz-366 Low-E Glass
Specialty windows in gable ends and above entry doors get direct sun exposure for long stretches of the day. Triple-silver Low-E coating blocks 95% of UV rays across the full panel, keeping that exposure from driving radiant heat into the rooms below throughout McKinney’s long cooling season.
Argon Gas Fill
Argon gas between the panes reduces heat transfer through the glass regardless of the unit’s shape. The insulating performance of the sealed unit is the same in a circle as in a rectangle, provided the edge seal is maintained around the full perimeter of the custom shape.
Perimeter Seal Integrity on Custom Shapes
The energy performance of any fixed window depends on the quality of the seal between the frame and the rough opening. On non-rectangular shapes, that perimeter is more complex and requires more care to flash and seal correctly. We treat it as a critical step on every specialty install, not an afterthought.
The opening is the hard part. The glass comes second.
Rough Opening Verification & Prep
Specialty windows are unforgiving of rough opening errors. A radius that’s off by a quarter inch reads as wrong from across the street. We field-verify every opening before the unit is fabricated and flag any structural issues before they become installation problems.
Flashing & Weather Barrier Integration
Fixed specialty windows are more vulnerable to water intrusion than operable windows because any gap in the perimeter seal has nowhere to drain. We flash and integrate the weather barrier at the rough opening before the unit goes in, on every project, every time.
Exterior Trim Matched to Existing Profile
Specialty windows are often installed alongside existing windows with established trim profiles. We build the exterior surround to match those profiles in material, dimension, and finish so the new unit reads as original to the home, not as an addition.
Fixed glass is a long-term commitment. Choose the right package for the exposure.
Tempered Safety Glass
Tempered glass is required by code for specialty windows in certain locations, including units adjacent to doors or within reach of a stairwell. We verify requirements for every opening and specify tempered glass wherever code requires it or the location warrants the added safety margin.
Decorative & Textured Glass
Privacy glass, reeded glass, and decorative textured options are available for specialty windows in bathrooms, entryways, and any location where light is the goal but direct view is not. Pattern and texture can also reinforce the architectural character of the shape itself.
Low-Iron Ultra-Clear Glass
Standard glass has a faint green tint that’s especially noticeable in shaped units where the eye follows the edge all the way around. Low-iron glass removes that cast entirely, giving arched and round windows a cleaner, sharper appearance against light interiors and painted surrounds.

What a well-installed specialty window does to a room and a roofline
Woodruff customers consistently describe two things after a specialty window installation: the room reads differently because of what the light does, and the house looks more considered from the street. Here’s what’s behind both of those outcomes.
Up to 95% UV blockage with Cardinal Lodz-366 Low-E glass, protecting interior finishes and furnishings directly below gable-end and transom specialty windows that receive unobstructed sun exposure throughout the day.
Measurably lower air infiltration at the rough opening perimeter when flashing and weather barrier integration are completed correctly, which is the most common point of failure on specialty window replacements.
A visually complete installation with paint-matched casing and matched exterior trim profile, so the finished window reads as original architecture rather than a visible add-on.


Fixed glass means no hardware, no operation, no maintenance cycle.
Specialty windows are fixed glazing by design. There’s no sash to clean on two sides, no hardware to lubricate, no weatherstrip to replace. The only maintenance is an occasional wipe-down of the glass and a periodic inspection of the exterior caulk line. For windows installed in hard-to-reach locations like high gable ends or stairwell transoms, that low-maintenance profile is part of what makes them the right choice.
Shapes that move light in ways a rectangle never will.
A half-round above a door floods the entry with morning light from an angle a standard window can’t reach. A circle in a gable end throws a beam that travels across the ceiling through the afternoon. Specialty windows are often chosen for their visual effect from the street, but homeowners consistently say the interior light quality is what they notice every day. The shape determines where the light lands and how it moves through the room across the hours.

Free In-Home Consultation & Field Measurement
We come to your home, assess the target opening, verify the rough opening dimensions against your shape goals, and walk you through glass and frame options. Most consultations take 60–90 minutes and in that time we will put together a plan that works with your schedule so we can get your project installed and completed quickly.
Step 2
Custom Fabrication & Scheduling
Your specialty windows are fabricated to the exact field measurements. Lead time is typically four to six weeks depending on shape complexity and manufacturer. We confirm your installation date in advance and keep you posted if anything shifts.
Step 3
Installation, Trim & Final Walkthrough
Our crew handles the full scope: rough opening prep, unit installation, flashing, exterior trim, interior casing, and cleanup. Most specialty window projects finish in a single day. We walk the finished installation with you before we leave.
