Thermo Tech Window vs Inline

I think Serious makes a good window, and I also like Thermotech and Inline. Serious makes a really good product with suspended film glass, the lighter weight makes the moving parts last a lot longer and you get more light coming through. Serious has been used in a lot of famous buildings, including the Empire State Building, plus they come with a lifetime guarantee. Thermotech is also great, they are more expensive but they have really great service, I recommend them especially if you don't know anything about what you want or need. Inline is my third choice but still good.

Customer Service Issue

We sent an email to ThermoTech trying to get a quote, but they never answered. That tells you something about their customer service right there. We decided to look at Fibertec and Inline instead. Inlines frames don't seem quite as sturdy, and I don't like the inside profile or the screen as much as Fibertec so we'll probably just go with them.

Thermo-Tech Windows vs. Gerkin

Thermo-tec makes windows that are serviceable, but not great. I'm a big fan of Richlin, but they use a pocket sill, which I'm not a big fan of, and they tend to be pricey. Gerkin is a good option, they make good aluminum and vinyl windows and they are priced very reasonably.

Thermotech Windows vs Fibertec

We've received quotes from both Thermotech and Fibertec and the Thermotech was 15K more than the Fibertec quote - all for the same number of windows (20+) and I believe the same quality of window (there might have been some minor differences but I think they were comparable). I couldn't justify the high cost of these windows and ended up going with Fibertec and I'm pleased. Our research showed Fibertec being close in price to Inline windows, but they aren't available in our area and I liked the look and design of the Fibertec more anyway.

Thermotech vs. Fibertec: Take 2

I also compared Thermotech and Fibertec windows as they are the only fiberglass options in my area. Thermotech is a well regarded window but they are expensive. Fibertec, on the other hand, had some mixed reviews, which I discussed with the rep and he said they had had some issues with some of their staff a while back but they have ironed it all out. The install worked out well and so far the windows are great, although I haven't even gone through a winter here, so I'll reserve judgement until then.

Contractor's Opinion

I sell ThermoTech frequently. There are actually two manufacturers, one in Canada at and one in the US at I am not familiar with the Canadian company, but the one here in the US is great. Their customer service team is very responsive and I very rarely see any problems with the product. I'd recommend them to anyone, and would definitely use them on my own house if I needed windows.
