How To Foam Insulation Board
Hi, I'm Tim Carter from AsktheBuilder.com. I want to talk about little about closed cell foam insulation and how is can be used to insulate the floor system in a shed or out building that has a wood floor. There are two benefits from this product.
First, I am using the closed-cell foam insulation, 4-inches thick, in between the floor joists. Each inch has an R-valve of 5. In this application, the foam blocks are just pressed fitted into place. So to keep them from falling over the years, we installed pressure-treated blocks to support the insulation.
The other benefit of this product is it is a tremendous vapor retarder. Lots of moisture will come up out of the soil under the shed and try to get into the structure. This insulation will block that moisture.
Just be sure you cut it nice and snug between the floor joints and you will be good to go. So remember, closed-cell foam insulation is a great insulator for floor systems.
LOOKING TO INSULATE BASEMENT WALLS, WHICH PRODUCT IS THE BEST TO USE. THANK YOU
Mr. Tim,
I’ve tried various different ways to see the video on insulation a crawl space. I can’t seem to get it up. Any ideas?
Turn off your computer or device, let it rest for five minutes, turn on and try again. The trouble is absolutely at your end.
Tim,
I got great assistance from this video. I have built a 100 sq ft playhouse suspended on a free-standing deck style platform. the floor gets cold in the winter (of course) so i needed a way to insulate a bit to make it more comfortable. While the installation will be a bit different (the deck has 2' clearance from the ground), this method is perfect for what i need. thank you. I had already purchased RTECH panels - which have an aluminum coating on one side both for thermal reflection and for a vapor barrier. this leaves me with just one question: should i mount with the aluminum facing inward or toward the ground?
Question for you Tim. I have already applied a vapor barrier to the ground prior to adding my joist and closed cell foam. I am trying to make use of a tall crawl space under our rambler. Are there any other considerations I should be thinking of?
Thanks,
Ken
There are many things you should consider. It's probably best we have a conversation: https://shop.askthebuilder.com/15-minute-phone-or-video-conversation-with-tim/
