This indoor patio door insulation kit is made of high-quality POF material, which is durable and has a long service life. It is easy to install and remove, and can effectively block out cold air, noise, dust, and sunlight. The kit includes 84-inch by 110-inch clear film and 1roll 1/2" (W)X 504"(L) double sided tape, which is enough to cover most standard-sized doors. The film is self-adhesive, so it can be easily applied to the door surface without any additional tools or materials. It is also transparent, so it does not obstruct the view from the inside or outside of the door. The insulation kit is not only useful for keeping out the cold, but it can also help to reduce energy consumption by keeping the inside of the door at a consistent temperature. It is an ideal solution for homes, offices, and other buildings that have indoor patio doors.
