What Tape Should I Use to Hold Insulation Film to Windows?

JVCC DC-4109RS Double Coated Film Tape The double-sided film tape we typically sell for adhering window insulation film to the interior of windows during the winter season is JVCC DC-4109RS tape. If the film is heavier and you need a tape with a stronger adhesive then JVCC DC-4199CS would be another to look at. These would be the closest double-sided tapes our converter stocks which are similar to 3M's 2145C product for indoor insulator film mounting. As far as these tapes' removability you'd want to test them first on an inconspicuous part of the window frame to make sure it removes as desired. Please also remember the more adhesive the tape you go with the harder it will be to remove in the spring. Also both of these tapes are coated with an acrylic adhesive which provides moisture, UV and temperature resistance; however tapes with acrylic adhesive need a few minutes to an hour for the adhesive bond to set correctly when applying them. See our blog entry on general instructions on applying pressure-sensitive adhesive tape for more detailed instructions. Thank you.

Some General Instructions on How to Apply Adhesive Tape

The following are some general recommendations or guidelines to follow when applying a pressure-sensitive adhesive tape:

  1. Make sure the surface you are applying the tape to is completely dry and free of any debris before the tape is applied.
  2. If any cleaning supplies were used recently on the surface please make sure no residue remains from the cleaning product (if so please use water to remove and then let it dry completely).
  3. Unwind the tape from the roll (if the tape has a release liner remove it now). During this step be careful not to contaminate the adhesive by touching it at all with your fingers since it will transfer natural oils over to the adhesive side. Also try to immediately bond the tape to the surface without entrapping air between the tape and the surface it is being applied to.
  4. Use some application pressure (it doesn't have to be that forceful) in order to achieve maximum bond strength. Make sure there is no gapping remaining between the tape and the surface it is being applied to which would allow water to come into contact with the adhesive-side of the tape over time. This would deaden the adhesive and shorten the life span of the tape.
  5. If the tape has an acrylic adhesive the dwell time the tape needs to be in contact with both surfaces (before it reaches it maximum adhesion) is typically 1 to 24 hours. For best results during this dwell time try to provide some application pressure (e.g. clamps, tape over it, etc.); also if holding an item vertically against a surface try and support the weight if possible.
  6. For even better adhesion you can also use an adhesion promoter or primer; can see some options at Adhesion Promoter/Primer on FindTape.com.
