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

Therma-Tru built its name on doors, but its window lines show up in plenty of Palm Beach homes, especially newer construction and remodel work. Salt air, humidity, and relentless UV do specific things to these units. Here’s what we see most often:

• Seal failure on Classic-Craft and Pulse series insulated glass. The desiccant strip inside the spacer eventually saturates in Palm Beach’s humidity. You’ll notice fog between the panes that won’t wipe off. We replace the insulated glass unit rather than the whole frame, which keeps the job under $400 in most cases and preserves the original trim work.
• Low-E coating degradation on south-facing units. Therma-Tru’s factory Low-E works, but after eight to ten years of direct Florida sun, the coating can start to haze. You’ll see a slight milky tint at certain angles. We swap in updated Low-E3 or comparable glass that matches the original sightline and bumps the SHGC down where it matters.
• Argon gas loss through worn glazing beads. On Therma-Tru sliding windows and hinged patio doors, the glazing bead can warp slightly with heat cycling. The gas escapes, the insulation value drops, and you’d never know from looking at it. We test with a thermal meter, then re-glaze and refill with argon or krypton, whichever the original spec called for.
• Frame-to-glass thermal bridging on older Slim-Line profiles. The original Slim-Line frames were narrower, which looks good but leaves less room for thermal breaks. In summer, the aluminum edge transfers heat straight through. We can retrofit with insulated laminated glass and upgraded weatherstripping that cuts that transfer, or replace the sash if the frame’s still square.
• UV fade damage around fixed transoms and sidelites. Therma-Tru transom windows sit high and catch full sun. The factory glass blocks some UV, but not enough to protect hardwood floors and upholstered furniture near west-facing entries. We install UV-blocking laminated glass rated to block 99% of UV rays, same thickness as the original, so the visual match is identical.

Therma-Tru’s own documentation won’t tell you most of this. We know it because we’ve pulled apart several hundred of these units in Palm Beach heat and humidity since 2011.

Our Therma-Tru Energy-Efficient Windows Process

Here’s how a typical job goes from your first call to the final walk-through:

1. 1
   You call (561) 782-7525. A live person answers. No voicemail tree. We schedule a time that works for you, and there’s no trip charge if you’re in our home county.
2. 2
   We inspect every Therma-Tru unit. Not just the one that’s fogging. We check glass condition, seal integrity, gas retention, weatherstripping, and frame alignment, then show you exactly what we found.
3. 3
   We price the fix in writing before any work starts. Fixed numbers, line by line. You approve exactly what we do. No change orders later.
4. 4
   We source the right parts. For glass, we use OEM-spec insulated units or quality aftermarket equivalents that match Therma-Tru’s original thermal performance. We’ll tell you which is which and why we recommend it. Warranty-safe practices on every job, so your original Therma-Tru coverage stays intact where it applies.
5. 5
   We do the work, test, and clean up. After installation, we check each unit with a thermal meter to confirm the insulation value matches what we quoted. Then we haul off the old sashes, glass, and any packaging.
6. 6
   You get our Done Right Promise. If it’s not done right, we come back and make it right. Ed Winslow’s name is on the business, and that promise means something on every job we leave.

What Therma-Tru Energy-Efficient Windows Costs in Palm Beach

Here are real numbers for the jobs we do most in Palm Beach:

• Fogged glass replacement on a single Therma-Tru insulated window: $180-$340, depending on size and glass type.
• Argon gas refill with re-glazing on one window: $120-$220.
• Low-E or UV-blocking glass upgrade on a small fixed transom: $190-$310.

• Whole-home window energy audit (up to 15 units): $150-$250, credited toward any repair you approve that day.

What moves the price: glass size, whether it’s tempered, whether the frame is square enough to hold a new sash, and whether you need OEM glass or can go with an equivalent aftermarket unit. We’ll tell you the difference and let you decide. Call (561) 782-7525 for an exact quote. Estimates are free, and so are second opinions on any written estimate you’ve gotten elsewhere.
