Insulate your windows to retain warmth and save money on heating.
IndowKIT is an easy, affordable solution for blocking drafts and lowering your heating bills.
Our kit snaps together in minutes to create an insulating window insert that blocks drafts, looks great, and is easy to install and remove!
What Is IndowKIT?
CUSTOM CUT TO YOUR MEASUREMENTS
Your IndowKIT will include custom cut aluminum framing and a premium insulating shrink film. With our patented thermal fin system, you can use a common household tape measure to capture your window's dimension and be guaranteed a seamless fit.
We'll manufacture your frame and have it shipped directly to you for easy assembly & installation.
Snaps Together In Seconds
Putting together your IndowKIT inserts is as easy as 1, 2, 3.
1. Snap together the frame pieces and corner leafs
2. Lay the film over the frame and lock it into place
3. Use a blow dryer to shrink the film into a sturdy pane
Voila - you have a window insert!
Premium Results For Half The Price
With IndowKIT, you get all of the benefits of a quality window insert - superior insulation, ease of removal, and aesthetic design - at a fraction of the cost of acrylic inserts.
Compared to bargain solutions that block the light or ruin the look of your windows - IndowKIT is the perfect choice for insulating your home on a budget.
How Does It Work?
SEE INDOWKIT IN ACTION
One you receive your IndowKIT, all you'll need is a pair of scissors and a household blow dryer to create your insert.
Snap the frame together, lock the film into place and heat it up - and you'll start seeing your insert magically come together.
A Smart Investment
DURABLE
Our premium Insulation film is highly resistant to damage and wear.
Unlike insulation films that are taped to your window - you'll get multiple seasons of use out of IndowKIT - and no sticky tape residue left on your window frame!
REPAIRABLE
If your film does get cut or damaged, you can apply new film and re-shrink to refresh your inserts.
Damage to frames can be easily repaired with a new frame section. Snap in the new piece, reapply a film, and your insert is as good as new!
UPGRADEABLE
Ready to upgrade to acrylic inserts? With our Upgrade Kit, you can upgrade from film to any of our premium acrylic insert grades.
Create a permanent thermal insulating panel, or add acoustic soundproofing, UV light blocking, and more to your existing frame with ease!
GUARANTEED TO FIT
Our measurement verification portal is easy to use. Once the dimensions are uploaded, our proprietary software will verify your measurements instantly. With our Snug Fit Guarantee, you can be confident your inserts will fit and perform as expected right out of the box.
