Figured I would throe this question out there to the community.
I live in Fl so my garage can get rather hot at times. I have been looking at ways to insulate it as best as possible.
the major culprit is the garage door of course.
Saw this kit at Lowes for insulating the garage door. Comes with large pieces of what looks to be Styrofoam.

Anyone had any experience with this kit? Would love to get an idea of its effectiveness before investing in the cost.
If it works as good as advertised then its worth the cost but its pricey without some feedback first.

Thanks folks.

Compare the price of that “kit” with the cost of the 4’ X 8’ sheets of Styrofoam. You can buy it in several different thicknesses and cut it yourself. HD has some sheets in 2” thick for $36 per sheet and also 3/4” thick for $17 per sheet. It’s pink but who cares about the color so long as it works.
I used the 3/4” stuff on my garage door panels. Cut to fit with a razor knife and held it in with construction adhesive. It was still on there when we moved from there after 8 years.

Fair point. The kit is like 70 bucks. Quiet a markup. I rarely go to HD. Lowes is closer and the staff of the closest HD sre less than pleasant to deal with.
But ill go check it out. Does seem a better price for a bit more work. But who here is afraid of a bit of work.
thanks.

I bought 2 sets from Groupon before, $36 each and they work great. It’s a bit chilly right now, but in my garage, it’s not nearly as bad. Same with during summer; when it’s humid and hot, it’s no where near what it is outside.

I had that stinking metal door, one that faces into the western sun in the afternoon. I tried filling it with insulation cut from a 1 inch 4×8 sheet. Eventually, I replaced the door with an energy efficient door. Much better.

I would think a foil faced radiant barrier would be more useful than just plain open celled foam. For what it’s worth…

I cut panels of the 1 in blue extruded foam to fit each metal rectangular section. Glued them in with foam adhesive and filled the gaps with aerosol foam. Works well here in Colorado, both summer and winter.

I did my door with the 3/4” foil faced foam sheeting that I bought in 4’x’8’ sheets and used expanding poly foam to fill the voids in and around the U channel structures. I was tempted to go with the thicker ridgid foams but read an article somewhere about the coil spring strength vs. added weight to the door. I have living space above my garage and the door faces east, and after adding the foam I found a 10 to 15 degree improvment in the space against exterior temperature, and am able to get it sweatshirt and jeans warm in the winter when we have 30*f or so outside, using a couple of ceramic heaters and a small fan. Biggest problem I’ve found is how to get the damn concrete slab warm, even in insulated boots my feet are freezing after a few hours..

I went with the foam sheets on my garage door. Home Depot was where I bought them. I cut them on my table saw, messy, but accurate. Each panel was made with two pieces, a large one and a smaller strip. The styrofoam doesn’t bend vey well. The door sections had two different heights of the panels
I didn’t need to use any adhesives as the styro fit in the channels of the door panels.
Amazingly, it added weight to the door, who would of thunk?

ChefHDan, I had the same problem but solved it by insulating the floor w/ Harbor Freight anti fatigue mats. I did all of the walk ways and standing areas in my shop and it has worked well for several years now. I started out by doing the standing areas in front each machine, then eventually connected them all together.
