How to Insulate a shop floor! 20x30 Workshop with Ridged Foam Board

[@user-ns5ne3jx6e]

Thank you for a great series. I've been using these steps to build a wooden floor in an existing shed. I suggest to place the foam boards at the bottom of the joists and create an air capsule below the plywood. Air provides good insulation as well, especially when its dry.

Thank you for watching. This has been a great build.

Could you just nail full sheets to the bottom of the floor joists? I’ve got a post and pier addition and last winter my floors were so cold in the winter I couldn’t walk on them without socks.

i was also wondering this please let me know if you get any info.

Yes

[@joseph7105]

or just place full sheets directly on top of joists and use longer screws when attaching plywood.

Jigsaw, that's clever.

It worked well. After doing this with razor knife and circular saw the jig saw works best.

Could u've place the foam board on the floor n go under the floor n trace out a number of the patterns then cut them out ...just a thought I know nothing about this kinda work tbh

[@sethcraftworkshop]

Each of my joists were just off enough that I had to measure and cut each one separately.
