Product as described

The product is as described. But the curbside pickup is what I'll talk about. This was my first curbside pickup experience. The young man who answered the phone was so helpful and he's the one who loaded both my orders. He was great. Wish I remembered his name.

Let the cold wind blow

I bought a new house...one of the bed rooms had a sliding glass door .During the summer you could never keep the room cool as the Sun beat down on the window most of the day ...bought two of the insulation boards 8x4 about the size of the Windows and under an hour had installed..no more problem ...summer or winter. Would recommend.

Cutting

So I bought 1 sheet, had to cut it in the parking lot to get it into my SUV. Used a razor knife and snapped it which leaves a very rough edge that you have to contend with. So at home, I used my 7 1/4 Inch Circular Saw to make my final cuts. Supper clean edges and way easier to fit them in. Yes, makes a mess so cut over your grass and use your lawn mower to clean up. Did this for the next 2 sheets I had to buy, very happy with the results

Garage wall

Insulating walls in between posts of garage before roughing in walls. Worked well as primary barrier.

Be careful when getting this delivered

Does not transport well when delivered by Lowe's. Ordered two sheets, and both had the corners dinged up a bit. Tip: Cuts well with electric knife, use a wallboard square as a guide, taping it down temporarily with duct tape. Square: Item #77676, Model #32410181

GReat Foam!

This Foam panel board is great. Its unfortunate that Lowes isnt. I ordered 4 of these and 4 of the 1.5" for pick up and a day later, no word that my order is ready for pick up.

Great Project Foam

I know this is supposed to be insulation but it works great for my Christmas train project. Wanting something more than the floor or a table I happen to see this in the store. As you can see the project Christmas train is coming along fine.

Skeptical at First

I bought this to insulate my garage door. I was somewhat skeptical at first, but after having it installed a few days, it has worked amazingly. It bends and flexes as much as you would need it too and as long as you have a sharp enough blade, it is easy to measure and cut.

Form board

Easy to cut and form where needed

Perfect

Only needed half a sheet but I will find things to do with the rest. Worked just the way I figured it would. Great product!!

Fomie

Nice light weight insulation, moisture barrier and insect preventer. Plus good for those school projects.

Best flotation material I ever used

I installed a center console in my boat. Boat being over 20 years old flotation was shot. I read somewhere about using this. 2” thick and fit perfectly in floor, will also add to walls ect. Very light weight, no way this boat will ever sink.

Very reliable product

Very reliable and useful. I'm using it underneath my inflatable hottun as a smooth surface and to help keep the heat in.
