About 3M Indoor Patio Door Insulator Kit for Large Windows and Sliding Doors
78% praised its long-lasting performance
The plastic seemed flimsy, but I found it to be quite durable. I was able to unstick and restick it to make adjustments.
I have been using this product for almost a decade and can often reuse the plastic the following year.
After 60 days of use, the film and tape have held up great.
80% found it easy to install
The installation process was easy and our great room became more comfortable after installation.
