Windowtherm FAQs
Q:
“I’ve been shopping for replacement windows. The salesman showed me some very convincing facts and demonstrations. How can Windowtherm technology possibly be equal to that?"
A:
There’s nothing wrong with considering replacement windows, and in many circumstances like broken glass or faulty existing windows, they are a good solution. However, since you’ve been shopping, you know that the cost of replacement windows can really add up, especially as you add options like triple paned glass and special ‘insulating’ gases.
Windowtherm offers the same instant comfort and energy savings by adding two extra layers of glazing to your existing windows. It also adds two pockets of trapped air. Trapped air is a great insulator. Each glazing layer stops a certain amount of cold air. And with our overall sealing of the window, we stop infiltration better than any regular replacement window.
Q:
“I already have storm windows. Why would I need Windowtherm insulation panels and why are they mounted on the inside instead of outside like regular storms?”
A:
Outside storms are only good for keeping out rain. They are deliberately designed to leak to prevent ice build up. Plus, the popular aluminum types waste a considerable amount of heat. By inserting Windowtherm inside a window, you place a tight vapor barrier on the inside (as it should be) which stops infiltration and condensation.
Q:
“I have an attractive house. Will Windowtherm be as good as vinyl replacement windows?”
A:
Yes. The beauty of Windowtherm panels is that they are virtually invisible from the outside and blend into your homes interior by matching the muntin (grid) spacing of your current windows.
Q:
“I just realized that your glazing material is plastic film. In a few years, won’t that start looking like the cloudy stuff they use for construction poly?”
A:
No. Most people don’t realize our glazing material isn’t glass until they touch it. It’s a special polyolefin film designed for clarity, long life and tensile strength. It is very different from conventional films. It also has no off-gassing issues to be concerned about. This film will last for years and if ever pierced can be cheaply replaced in just minutes.
Q:
“I have non-standard window sizes. Will Windowtherm insulation panels fit?”
A:
Yes. Each Windowtherm panel is custom cut to fit your exact window. We can accommodate curves and any rectangular or slightly crooked frame is no problem.
