Condensation Problems in Workshop

[John McCullaParticipant @johnmcculla]

Slow but steady progress is being made!

Needs more noggins in floor, especially inline with door.

[John McCullaParticipant @johnmcculla]

That’s maybe a bad photo for showing the ones in line with the door frame. What spacing would you recommend?

[Dave HalfordParticipant @davehalford22513]

The ones close to the wall are wasted and the edges of the joining floor boards need full support or you will feel the sag as you step on the joint

[BazyleParticipant @bazyle]

As Dave suggests plan your floorboards first for the joints. Also plan benches and machines so they are supported, even if just a small extra block in the middle of a gap. Otherwise just walk in like you would when finished and note where each footstep lands – put a noggin there. If you are using solid insulation though it will provide some support if you can line it up level with the frames.

I built a workshop a few years ago – 2018 as I recall. It’s a building within a large barn which is 100 foot long, 20 foot high to the peak of the roof, and about 35 foot wide, timber structure with a wriggly tin roof – an old sawmill here in France.

The workshop is about 5.28 metres long by 3.2 metre wide.

I built it using 50 sheets of OSB 3 from the UK at £10 per sheet + loads of 2 x 4 cls x 2.5 metres – forget the price – so the walls and roof are nominally 4 inch thick, double skin 11 mm osb 3, insulated with rockwool, no ventilation and as airtight as possible apart from when the doors are opened.

This past week we have had really cold temps, for here, temps of – 1.0 to +1.0 temps for a couple of days. then it went to + 11 C  yesterday with rain so immediately very humid

Everything in the barn was dripping with condensation, so checked the workshop + 8.0 C – no heating and no condensation.

I’ll post some photos when I can find them.

I have used this model dehumidifier (although it used to be Delonghi) for years to keep my workshop dry. It works regardless of the temperature and has a hose that leads moisture outside of the workshop. It provides a small bit of heat and uses some electricity obviously. I leave it on medium setting. My shop is 50M2 and stays dry, no rust on exposed, unprotected metal

The only precaution is to keep the drain hose short and with a good drop or it will freeze and the dehumidifier tank will fill and the machine will automatically shut off.

It is the only appliance that i buy the 3 year warrantee on and it has paid off  and they sent me a new one no questions asked.
