BACKGROUND
After we replaced the wood stove in our Northern Michigan cabin's garage, insulating the garage door was next. It faced the cold north winds, and really reflected the cold right into the garage.
My wife had been "suggesting" that the door should be insulated before winter came. Winter came, and her "suggestion" became stronger. I couldn't put it off any longer.
We bought a DuraCore HP garage door insulation kit on sale for around $30.00 at our friendly Menard's Home Store.
The door was ten feet wide. Each insulation panel was 24 by 48 inches wide, just a few inches wider than individual door panels between the vertical rails. I took a straight edge and marked the correct width. I then did a scoring cut with a utility knife after lining up my mark on the edge of the work table, and snapped the panel on the line.
The insulation panel was 24 inches wide from top to bottom, and was the size of the inside of the opening, but there was a lip on the top and bottom of each door panel that made the opening slightly smaller than the panel size. So, I had to place the top of the insulation panel into the slotted lip, and bent the panel, bowing and flexing it into the opening.
This was a fast, cheap fix that really helps keep the cold out.
