Duck Max Strength Clear Plastic Roll-on XL Patio Window Insulation Kit, 84 in. x 112 in.

This kit would be more helpful with three key improvements: (1) Stronger Adhesive - the present adhesive header strip isn't strong enough to support the entire weight. Buyers also need the additional roll(s) of double-sided adhesive. Which, in and of itself, is more akin to ' scotch tape ' . For much greater reinforcement, I bought a Packing Tape Gun because I know the window treatments will need it during the Midwest's subzero temps and wind gusts. (2) Thicker Plastic - This is not much denser than Dry Cleaner plastic. I placed it over My old apartment windows but still feel cold air permeating and that's before Winter season windy conditions set in. This plastic treatment is more ideal for regions with mild Winter seasons in which temperatures are unlikely to drop below 60 degrees Fahrenheit and without strong wind gusts. (3) Perforated Sections - The items descriptions indicate the window number of dimensions and ideal dimensions. However, ' this Roll-on ' Treatment just comes out in a single roll. Therefore, careful measuring is needed for accuracy. This works more or less, given the nature of environment that consumers live in and related weather conditions. My advice for potential buyers is to do your research and make comparisons to see if this is for them.
