NASA Tech Single Car (Speical Size 5 Panel) (Non Fiberglass) Reflective Foam Core Garage Door Insulation Kit (Fits 5 Panel 9x7 9x8 Kits)

This is mostly good news. The two sided tape worked better then expected, even in cold <35 degree weather. The Vendor had excellent support when I called with a question. I ordered the 21" version, and the roll that arrived was 24" which is per plan according to the Vendor. 24" turned out to be a FEATURE as my door had two 21" panels (the ones i pre-measured) and two 24" panels (the ones i didn't measure). whewThe product appeared to have been cut from bigger sheets of insulation, and the cut quality was mediocre. Laying a square edge parallel to the cut edge of the insulation should variability of up to 1/4 and inch, which makes getting a nice tight seam difficult.

Installed as described. Tape and knife was included. Will see this winter how much difference it will make.

Very easy to install. Seems to help with both heat and sound.Good product.

It has been up and working well for the past month. It even stayed in place after an unfortunate incident with the back of the car and garage door. Highly recommended
