You are building the entire thing with concrete slabs? As in floor, walls and roof?

The two most common methods is hardcore, DPM at least 100mm PIR, concrete slab then screed. Or hardcore, DPM, slab, PIR, screed.

Or you can always do a floating floor over the PIR on top of the slab.

This brochure gives you everything you need and all the U values: www.kingspan.com/content/dam/kingspan/kil/products/thermafloor-tf70-gb-and-ireland/kingspan-thermafloor-tf70-brochure-en-gb-ie.pdf

Thank you for the reply. I'm trying to make a concrete slab with scaffolding borders once I insulate and concreate and take the scaffolding borders away after the concrete dries up wouldn't the insulation show on the edges

Why do you want insulation in an outhouse, I presume you just mean a posh shed with no heating.
