Product Information

Full details

The DIVCHI Window Insulation Kit is an ideal solution for homeowners and renters seeking an affordable way to improve thermal efficiency and eliminate cold draughts. By creating an airtight seal over your existing windows, this kit helps regulate indoor temperatures year-round, keeping heat inside during winter and cool air trapped during summer. While it is highly effective at reducing heat loss and blocking dust, users should note that the shrink film is a single-season application and will need to be replaced if removed.

FAQs

Can this be used on all window types?

It is suitable for most sliding and casement frames, provided there is a flat surface for the tape to adhere to.

Will the adhesive damage my window frames?

The tape is designed to be removed easily, but it is recommended to peel it off slowly to prevent peeling paint or finish on older frames.

Can I open my window after installation?

The film creates an airtight seal that is designed to stay in place. You will need to remove the film to operate the window.

How much area does one kit cover?

Each kit includes one 1.57m x 1.82m sheet of film, enough for one standard-sized window.

Does this block UV rays?

While the film is transparent, it is primarily designed for insulation and draft reduction rather than UV protection.

Troubleshooting

The tape is not sticking to the window frame

Ensure the frame is completely clean, dry, and free of dust or grease before applying the adhesive tape.

The film has wrinkles after installation

Use a hair dryer on a medium-heat setting to gently shrink the film until the wrinkles disappear.

Film is tearing during the shrinking process

Keep the hair dryer moving constantly and do not hold it too close to the surface of the film.

Pros and Cons

Pros

  • Significantly improves indoor energy efficiency and comfort
  • Easy to install and remove without damaging window frames
  • Transparent finish maintains natural light and clear views
  • Cost-effective alternative to expensive window replacements

Cons

  • Film is intended for single-season use and cannot be reused
  • Requires a hair dryer to shrink the film for a wrinkle-free finish
  • Tape may require careful removal on delicate painted surfaces

Setup, Compatibility & Care

To install, first clean your window frame with rubbing alcohol to ensure the adhesive tape bonds correctly. Apply the tape around the entire perimeter of the frame. Peel the backing off the tape, press the film firmly into place starting from the top, and smooth it out. Finally, use a hair dryer to shrink the film until it is taut. For care, avoid using sharp objects near the film, as it can puncture. If you notice any small gaps where air is escaping, you can reinforce the seal with extra adhesive tape or patch small tears with clear packing tape.
