        The opening cannot be larger than 60 x 40 for this size kit to work. You would need a larger size.

                  Great product and easy to use. When put on perfectly, you can't even tell the sheeting is there. Just wish there was more double sided tape, I had to use masking tape to finish the box.

                  Quick n easy putting up but the plastic is very thin.

                  Relatively easy to install. We found that the bigger kits were easier to install than the smaller ones (42x62). We haven't used a blow dryer like the instructions call, but again, we haven't had any issues with installation. How much it actually helps, we're not sure, but if anything it's more of a peace of mind.

                  The box says “Crystal clear film”. Yes my windows are clean. Now they look like they have never been washed.

                    Cheap product
                    I had purchased this product a couple of times before and it always kept the draft out from my windows. This is an extremely cheaper material as the film is super thin and tears easily. The film to cover your windows was definitely thicker. It is still cold in my room. I won't be purchasing this brand of product again. Why be so cheap??

                      AMAZING for insulating whole house fan
                      So i have a whole house fan that comes in very handy at times during the summer time even though i have central AC. Its more of a hassle to uninstall during the winter than its worth. So i bought this to insulate it so cold air doesn't get in and man i am amazed at how well this works! Heat gun from Home Depot and it did a great job shrinking it as well. Ill be using another one of these for my bedroom window as well bc the head of my bed it close to it and the cold air seeping in is annoying.

                        Worked for a month
                        I put this over a window to block the cold from coming in in the winter. The shrink feature worked well initially, when I hair-dried it. The surface was very smooth and I was impressed. However, after about one month, the tape (not film) started peeling away from the window (frame is made of painted wood, one of the surfaces explicitly claimed on the box). I had to put duct tape and a battery on top to keep the film from falling away completely from the corner (see pictures). I expected more.
