I am using a Frost King window insulation kit on a window. Can I skip the hairdryer step and still get a good amount of insulating effect?
I am using a Frost King window insulation kit on a window. The way these work is that you tape a plastic sheet to your window frame (or some surface surrounding the window), then use a hairdryer on the plastic sheet to pull it taut.
My window frame is very bumpy (not a nice flat surface for me to stick the sheet onto), plus there is a window air conditioning unit sticking out in the middle (I can't take it out). Unless I want to cut the included plastic sheet into a more complex shape, the hairdryer step described above causes the plastic sheet to pull away from the tape's contact surface as it is drawn taut.
So my question is simple: Can I just skip the hairdryer step if I don't care what the end product looks like, or is the hairdryer step necessary to produce the insulating effect? Will I still get some benefit if I skip the hairdryer step?
