Yes. All our films are manufactured with a durable and crystal clear UV cured hard coat that protects the film from scratching and damage during routine cleaning operations.
Not very well. The sound attenuation properties of window film are practically insignificant. It certainly would not justify the cost if they are to be used for this purpose. We do not have any actual data.
Installing window film is one of the easiest do-it-yourself projects there is. But like all home projects, good preparation is critical – starting with a clean window is key to ensuring the best result. All of our films are made with a dry adhesive that is activated with a soap and water solution, so the film will not stick to itself as you peel off the liner or move it around. In addition, there is no sticky residue, no messy clean-up, and no extraordinary skill involved.
Here is the basic process:
- Clean the inside surface of the window (films are always applied on the inside)
- Remove the protective liner from the film using the applied tab (exposing the adhesive)
- Spray the film and the window with the soap/water mixture
- Apply the film to the window
- Squeegee out the water and trim the edges.
For complete instructions, please visit our installation instructions page.
Concord Window Film should always be installed on the inside of the window. The film will stick to the outside, but it will greatly reduce the life of the film. This is because the UV stabilizers are incorporated within the film’s mounting adhesive, so the adhesive side must be facing the sun (installed on the inside, facing out).
Our films are removable, but they are not reusable. Concord Window Film’s ComforTech™ Ceramic Series is an adhesive-backed film that is made to be permanently installed and last decades on your window. For instructions on how to remove window film, please click here.
Yes, all of Concord Window Films ComforTech™ 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 occurs 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.
No. Films must be installed on glass only, or surface damage may result. If you install the film on any type of plastic (such as Lexan or Plexiglas), bubbles will form underneath the film.
No. Concord Window Film will only adhere to smooth glass surfaces. The films will not adhere properly to glass blocks, textured, sandblasted, or other types of non-smooth surfaces.
We’ve provided a small tab on the liner side and a tab on the film side of each piece of Concord window film in our kits. The tab that says “Peel Here” is on the liner side of the film; the blank tab is on the film side. Pulling the tabs apart will allow you to separate the liner from the film. For a visual, watch our video on removing the liner.
If you’ve purchased a roll of film, you can use pieces of plain scotch tape to remove the liner. Refer to the video above for placement and technique.
Concord’s ComforTech™ Ceramic Series Film can take up to 30 days to fully cure depending on conditions. For the best results, please do not wash the windows until 30 days after installation.
Common window washing solutions may be used to clean Concord Window Film, along with a soft cotton rag such as an old T-shirt.
Avoid any abrasive cleansers or towels. We suggest using the same water & Slip-Tack mixture that you used to install the film (one teaspoon of Slip-Tack to a quart of water).
Our films are as durable as the paint on a car.
