The birds are chirping, the flowers are popping, the longest day of the year is just around the corner, and it’s time to think about removing and storing your Insulating Window Inserts! If you have central air conditioning, you may consider leaving in your inserts all year to keep the cold air in. But definitely remove south-facing inserts, as excessive heat can stress the plastic. Here are some tips on how to safely remove and store your inserts.

Removal: Inserts should be gently removed using the special 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 plastic.

Storage: Plan ahead for storage. Go over the route from 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. Try and select an 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 the back of a closet are possibilities, but check to insure there are no sharp protrusions or snag points. Do not store in closed plastic bags. Air circulating prevents potential of mildew.

Keep in mind that it is the foam seal around the edge of the window that insures a tight fit. It’s important to try and 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. 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 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.
