As an independent Therma-Tru service provider, Winslow Windows & Doors handles arched, radius, oval, octagonal, and oversized custom openings across Palm Beach, typically completing most custom window replacements in two to three weeks from template to install.

This page is for Palm Beach homeowners who own Therma-Tru windows, specifically the shaped or oversized ones, and need to know what can be fixed, what should be replaced, what it costs here, and who can do the work without voiding a warranty or botching a load calculation. If you have a round top window over a front door, a curved transom, or a geometric clerestory, this is your playbook.

How Therma-Tru Products Fail - and How We Fix Them

Therma-Tru earned its reputation in entry doors and fiberglass frame windows, and that fiberglass DNA is exactly what shapes the failure patterns we see in Palm Beach. Custom shapes amplify every one of them because there is no stock sash sitting on a shelf when something goes wrong. Here is what we actually see in the field:

• Fiberglass frame corner separation on geometric units. Therma-Tru’s fiberglass frames are strong, but on sharp-corner shapes like octagons or trapezoids, thermal cycling in Palm Beach heat can cause the corner welds to microfracture. A window that looks straight from three feet away starts showing a hairline gap at the mitered corner. This is the number one failure we see on non-rectangular Therma-Tru units in coastal properties. We fix it with a structural corner reinforcement and reseal, not a caulk smear.
• Radius and arch segment seal failure from salt-driven glass movement. On Therma-Tru round-top and arch units, the glass sits in a channel that depends on a continuous glazing bead. Ocean air accelerates seal degradation, and the curved geometry means any play at the bottom of the radius telegraphs to the top. Owners report condensation inside the glazing or water tracking down the interior of the curve. We remove, clean, and re-glaze with a marine-grade sealant, then re-set the unit to spec.
• Warped sash on large trapezoid and oversized openings. A six-foot-wide trapezoid above a sliding door is a lot of surface area for a light-duty sash. In Palm Beach’s afternoon sun, unshaded west-facing Therma-Tru geometric windows can rack out of square enough that the operators bind. The fix often involves a reinforced sash frame or, on severely degraded units, a full replacement using a heavier-gauge fiberglass spec than the original.
• Interior sweating on the Palm Beach waterfront. This is not a brand defect, it’s physics. Therma-Tru’s fiberglass frames are thermally efficient, but humid ocean air meeting cold interior glass produces condensation if mechanical ventilation is poor. We see this constantly in Palm Beach beachside condos with fixed arch windows. Sealing air leaks around the rough opening and confirming the unit’s weep system is functional solves most cases without replacing glass.
• Fogged insulating glass on older Therma-Tru custom shapes. Most Therma-Tru shaped units from 2008-2015 used a dual-seal insulating glass unit. Once the secondary seal fails, argon escapes and the glass fogs. On an arched transom over a double door on El Brillo Way, that means ordering a custom-curved IGU with a lead time measured in weeks, not days. We template the curve digitally, order the replacement, and handle the install so the customer doesn’t touch a thing.

Our Therma-Tru Custom & Geometric Windows Process

When you call Winslow Windows & Doors about a Therma-Tru custom shape, here is how the job actually goes. It starts with a live person answering the phone, 24/7, and it ends with the same owner accountable for the result.

1. 1
   Call and describe the window. Tell us the shape, the rough location in the house, the brand markings if visible, and what it’s doing or not doing. We schedule the free estimate then and there, no trip charge in our home county.
2. 2
   On-site measurement and diagnosis. Ed or a background-checked, uniformed technician measures the exact opening with a digital template on custom shapes. Standard tape measures don’t capture a radius well enough for a correct IGU order. We document everything and give you a written, line-item quote before we leave.
3. 3
   Parts decision: OEM or better. For Therma-Tru units still under warranty, we always source approved components and follow warranty-safe repair paths. For out-of-warranty work, we quote quality aftermarket parts when they exceed OEM spec, and we tell you which is which, on paper, with pricing.
4. 4
   The repair or replacement. Our install team handles the demo, the rough opening prep, the new unit set, flashing, interior trim, and exterior finish. On oversized or geometric openings, we spend extra time on the rough opening framing because that’s where future sag starts.
5. 5
   Test and walkthrough. We operate the unit fully, spray-test the exterior from the outside for leak paths, check the interior for daylight gaps at the frame, and walk you through what we found and what we did.
6. 6
   The 36500-Day Done Right Promise. If something isn’t right, we come back and make it right. That’s not a limited-time warranty with fine print. That’s Ed’s word, and his name is on the truck.
