Can I install the film on double pane windows?

Yes, all of Concord Window Films ComfoTech™ Ceramic Series products are made to be installed on single or double pane windows less than 40 square feet in size.

You should know that any excessive heat on a window can lead to rupturing of the window seals (the units will fog up) or to glass breakage due to high thermal loads. This situation is well known to the entire solar film industry. Concord suggests that all customers evaluate their window conditions before purchasing any window film by using our handy guide to determine if your windows are a good fit for window film.

Please note that thermal shock and seal failure occur even on windows where no window film has been applied.  Less than 0.1% of all windows in The United States have window film applied to them, yet windows can and do break every single day.  This means that 99.9% of all windows that break do not have window film on them.  Because of this, Concord does not offer a thermal shock or seal failure warranty.  If your application requires this type of guarantee, you should consult a professional installer.  Be sure to inquire about any exclusions, limitations, and deductibles that might apply.  You should also ensure that the particular film you and your professional installer agree upon is covered under the glass warranty program.
