Two in the front, and two in the back, and they had no insulation. If you ever buy a new garage door, pay extra to get the insulated panels, otherwise, somebody may have to retrofit insulation later on.<\/p>\n<p>I used 3 kits from Owens Corning that comes with R-8 fiberglass bat and plastic mounting clips. Because I&#8217;m only using it on the windowless bottom 3\/4 of each door, I was able to \u00a0 use 3 kits to insulate all 4 doors.

I put up 12 foam squares at a time, and then put up 12 clips. You want to roughly center them in the openings. Where there were support bars, I centered into the remaining opening.<\/p>\n<p><a href=\"https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2017\/09\/IMG_20170809_125235.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-4418\" src=\"https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2017\/09\/IMG_20170809_125235-1024x768.jpg\" alt=\"\" width=\"584\" height=\"438\" srcset=\"https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2017\/09\/IMG_20170809_125235-1024x768.jpg 1024w, https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2017\/09\/IMG_20170809_125235-300x225.jpg 300w, https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2017\/09\/IMG_20170809_125235-768x576.jpg 768w, https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2017\/09\/IMG_20170809_125235-400x300.jpg 400w\" sizes=\"auto, (max-width: 584px) 100vw, 584px\" \/><\/a><\/p>\n<p>Then it&#8217;s just a matter of measuring each opening, and cutting your fiberglass batt&#8217;s about 1&#8243; wider. The height comes pre-cut from the factory for standard garage door panels.<\/p>\n<p>The kit includes a pair of medium plastic gloves, and you&#8217;ll also want a long sleeve shirt when handling the fiberglass. Then you just push the batt into the opening. After you are happy with how it is centered, you push down to find the end of the plastic clip, cut a small X in the vinyl with a razer knife, and push a mating clip onto it. The finished door is nice and white and puffy.<\/p>\n<p><a href=\"https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2017\/09\/IMG_20170811_090345.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-4417\" src=\"https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2017\/09\/IMG_20170811_090345-1024x768.jpg\" alt=\"\" width=\"584\" height=\"438\" srcset=\"https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2017\/09\/IMG_20170811_090345-1024x768.jpg 1024w, https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2017\/09\/IMG_20170811_090345-300x225.jpg 300w, https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2017\/09\/IMG_20170811_090345-768x576.jpg 768w, https:\/\/www.summet.com\/blog\/wp-content\/uploads\/2017\/09\/IMG_20170811_090345-400x300.jpg 400w\" sizes=\"auto, (max-width: 584px) 100vw, 584px\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<p>So far, friction and the plastic clips have held in all the fiberglass batts just fine.
