Removing and storing your Inserts

Removal and Storage of Your WindowDressers Inserts

WindowDressers Window Inserts are built with wood frames that are shrink-wrapped with almost clear polyolefin film. With proper care, they should last for many years. Caution should be used when installing them, removing them, and storing them to prevent snags or puncture.


Inserts should be gently removed using the paint key delivered with your windows. You can also use a spatula. Just slip it between the insert and the window to break the seal. When replacing the Inserts in the fall, pressure should be applied to the wood frames, not the unsupported polyolefin film.

Selection of Storage Location

Plan ahead for storage. Go over the route from each window to your storage location, staying alert for potential snag points. Any sharp object, table edge, door latch, jewelry, tools, bolts or nails protruding from objects or walls represent a significant hazard. Select a storage area away from foot traffic – a place that will not be subject to having objects around it moved. A dry basement is often a good choice.  We suggest standing them on small bubble wrap to prevent moisture from being absorbed. Behind a bookcase or in the back of a closet are also good choices if there are no sharp protrusions or snag points. Do not store in closed plastic bags. Air circulating prevents potential of mildew.

Important Storage Tips:

  • Keep in mind that it is the foam seal around the edge of the window that ensures a tight fit.
  • It’s important store windows on edge, leaning against each other with a small space in between. Do not store windows flat on top of each other.
  • The supporting on-the-ground edge should be on a flat surface so that no dents are made in the foam edging.
  • Do not store inserts in direct sunlight. UV exposure degrades the foam gasket.
  • Small bubble wrap creates a moisture barrier on cement floors and a soft thin landing.
  • Consider placing an old sheet or cloth over the windows to reduce the dust or debris that may fall on them during the time they are in storage.
  • Post a warning sign noting the inserts’ vulnerability.Consider storing inserts with the label at the top. When inserts are installed, the foam on the bottom gets compressed more than the other foam edges due to gravity. The label is on the bottom when the insert is installed. Storing inserts with the label on the top will give the bottom foam a chance to “rest” and expand during the off season and will prolong the life of the bottom foam.
  • Consider the possibility of leaving some inserts in place during the summer months if you do not plan to open the window. However, do NOT leave inserts in skylights or other south-facing windows exposed to direct summer sun. Excessive heat trapped between the window and the insert can damage its film.

Damage Repair 

Small tears and punctures should be repaired immediately with transparent packing tape.  Common “Scotch Tape” (and equivalents) do not have sufficient adhesive strength or resistance to yellowing. If a tear is too big, the insert’s polyolefin film can be replaced for $10 each provided you drop off and pick-up the insert at any local workshop. Please bring stripped frames only.  White tape is difficult to remove. Cutting through the Poly to loosen it and pulling at the corner where the white tape begins gives you a better chance of striping all layers off at one time. The old white tape you can’t get off by scraping can be left in place.

If you can not drop off the damaged insert at a local workshop, contact WindowDressers support at 207-596-3073 or email at to make other arrangements.
