    Not a bad sketch that. You could fill underneath your tongue and groove with squirty filler. Even drill suitable holes in the t and g floor and fire aerosol filler into it at appropriate intervals to fill up the cavity. Then plug the holes (I've used car body filler for carpentry jobs as it's so much better than so called wood filler).

    Like has been said already at the end of the day it's a shed and you won't be living in it. If you over-engineer the insulation it will become an over-expensive shed.

    Yes done this thanks

    Would that not then raise the internal floor height or over all building height depending where you attach the shed walls

    You could be right, maybe this is just massive overkill, I am planing to insulate the inside at some point, clad the walls (mostly for security) and add another layer of glazing. I just thought I would take the opportunity to do the floor now. My preference would have been to build one but with the current weather, need for a shed quick, plus the likely hood of moving within 3-5 years I thought pimping a factory shed was the easier option.

    I mean use the car body filler to plug the holes you've drilled. Aerosol foam filler for the insulation. I just re-read that.

    I secured my shed against seige by track suit wearing bar stewards by internally lining with exterior grade ply and fixed with dome headed coach bolts (nuts on the interior obviously). This spec of ply lasts for years (you don't have to treat it but you could if you wanted to).
    You could either line in between the ply and the shed wall with rock wool or for a firmer job use aerosol foam. Insects or mice may make nests in the former so I'd go for aerosol which is pretty much uninhabitable when it's cured.

    whilst i would agree the payback will be poor on a short lived shed the possible damage to expensive tools or equipment will help balance out the cost along with the bearable summer cool from insulation
    also a well looked after shed will easily last between 10 and 50 years

    I'm a big celotex fan, I insulated my man cave with 100mm roof and walls and 45mm + 50mm poly in the slab floor, but its expensive. For this application, I'd look at loft insulation or 25mm boards tops (unless thicker boards are similarly priced).

    remember that heat loss is only ~15% through the floor, 25% out the roof and 35% through the walls.

    I helped my grandad build a shed in 1975. He had an old tin bath on top of an oblong bonfire and had a 50/50 mix of used engine oil and creosote warming up in the bath. Timbers were either soaked in the bath or painted with the mix. It stank to high heaven and ruined me clobber but that shed is still standing 41 years later. I drive past his old council house quite regularly and see it down the back garden. Not an environmentally friendly product to use to treat a shed I'll admit but it soaked in lovely.

    Quite. He smoked 50 Park Drive or Senior Service fags a day. He was the boilerman at a webbing tape mill hand shovelling coal into a big old boiler. He drank a gallon at lunchtime at the pub next door to the mill and after work he'd crack open his home brew. He never went to bed before midnight and got up at five in the morning. He was 96 when he died. I miss him.
