What do you folks recommend for insulating a "model" shed

As I have an away from home work shop, I was thinking of buying a shed for use at home for modelling jobs that can be done here. I know somewhere on this forum there is a thread covering insulating and lining of sheds, but darned if I can find it (the forum search engine seems a bit inadequate for this). Can you point me in the right direction? Thanks.

My shed is concrete block and its lined on the outside. Firstly a sheet of polythene, then 1" foam and them 5mm ply with about 3 coats of paint. I've retrofitted 3 air bricks at varying heights and locations and have an argos dehumidifier and oil filled heaters from the range. That way the shed breathes and is, touch wood, damp proof. The roof is felted and then topped with corrugated plastic roofing sheet.

Same could be done with a wooden shed as long as there are vents for the wood to breath.

I used various brands of insulation like Celotex etc which was typically 60mm thick, the best bit was it was all free and legal from some local building projects.

Talking to the site manager it transpired I was doing him a favour by taking away offcuts, damaged bit and unused unpackaged materials as it would have cost them skip space to have it removed.

I've insulated mine with 50mm polystryene, cut back to 45mm (by using a bow), and covering the whole lot with 9mm tongue & grove. Had to be 45 mm , as the timbers where that, and 50mm protruded. Took a while, but was worth it. I have also used 3mm acrylic to insulate the windows.

It is worth insulating, and worth the extrra bit of work and cost.

Not may builders on here?

Celotex or Kingspan PU foil backed insulation is available in sizes from 25mm to 120mm from builders merchants (Jewsons, Travis Perkins, Wicks etc)

Depending where you go, how much you want and if you haggle a price 50mm costs from £21/sheet to £35/sheet (8ft x 4ft)

Much better than polystyrene insulation and damp resistant but if you're using it in a shed or timber building be sure to fit a vapour barrier i.e breathable fabric roofing felt, or leave a ventilated air space between the insulation and the timber walls.

I have a small business based in Kent that specialises in modelling sheds, powered, insulated and fitted with special building benches. Some good advice above but celotex/king span is definitely the way to go.

A good dust extraction system helps keep the moisture level under control.

Happy to do long distance jobs for a fellow modeller, even if it is just the tech support.

I have just bought a concrete garage as a workshop size 22ft * 10ft

It has a cement based red roof sheet & a couple of UPVC windows & a metal up & over door plus a metal side door

I have insulated it by wiring 50*25mm battens vertically to the bolts on the panel joints then putting 25mm celotex between the battens. On the underside of the roof I have put 25mm celotex between the purlins held in place by 18*18 beads nailed to the sides of the purlins I have also glued celotex on the back of the garage door

I have 2 No infra red heaters along with loads of lights & plugs at 600 ccs all round & the place is dry & very warm

the celotex is covered with a sheet of 4mm ply laid 4ft high from ground level then a half sheet above this to give a height of 6 ft. Above that the celotex is exposed but not likely to be damaged.

The 23 sheets of celotex cost me £ 10-00 plus VAT from Travis Perkins delivered( needed a bit of negotiation - I had to try 2 branches to get that price )

I will use the workshop to build & store model planes plus my metal lathe & milling machine & bandsaw

So far no sign of damp etc
