Insulation

[Mint101]

Has anyone ever used pink styrofoam sheets for insulation? I have some for a shed and I don't know how good of a job they will do against heat or wind.

This kind of insulation does have an R rating, like the roll or blanket types, but I know it's pretty low, like R-2 or R-5 depending on how thick it is. Maybe check at your local big box home store to see what similar thicknesses are rated if yours doesn't have the rating printed on it.

pink or blue will work fine. two inch in generally sufficient. use a good adhesive and cut it so it fits tight in the stud space. where you have odd cuts to make, fill the voids with max expanding foam,

[Drywall DIY Guy]

This is very good insulation with R-value a little higher than fiberglass battes, when installed correctly. When using this type of insulation, you need to fit it tight in wall spaces and even caulk edges if needed - it has to be snugged in air tight or cold air will pass around it. Then, place a vapor barrier over the foam just under the drywall or whatever wall material you have.

This is also the type of insulation used for underneath slabs.
