Didn’t know that. Will search…

I looked into that and realised that maybe I should think about using mineral wool insulation instead, hence me coming round to an EPDM roof. Suffice to say it’s still at the drawing board stage and there’s the small matter of us not having spare cash to build I’d before selling our house so my man cave will be built after the house.

I’m guessing you’ve done a few then - are they noisy during rain? Would they conduct sound a lot (my man cave might accidentally have a fairly robust sound system, one never knows….)

For reasons I can’t identify I’ve been thinking about this swimming pool question. I think the water in the centre only needs to be 3 feet deep. That’s the height of a kitchen worktop. So would it make it a lot cheaper and easier if you just dug down a bit And allowing for walls slightly higher than the water level you ended up with at least 2/3 of it above the floor. Would that make it an awful lot cheaper and easier?

4degrees after deflection according to the Kingspan data sheet. But if a builder doesn’t want to do something it might be dangerous to insist.

I’m a wrinkly. Even when I was working I’d always prefer to do stuff myself so I tend to price my time is at zero unless it’s something I don’t fancy doing. Then my hourly rate in frankly extortionate lol The thing that put me off the insulated metal roof sheets was the idea that when raining it would sound like a biscuit tin.

My man cave will be a similar area to the OP’s garage, and I initially planned to use the insulated metal sheeting as the roof. When I priced up doing a slightly better insulated EPDM roof it worked out a fair bit cheaper, rather less than half the price of Kingspan. The difference may be installation costs as I’ll be doing it all myself, once funds allow. Have I missed something?

Crumbs. How do I ensure I get a suitable material for my downstairs floor/UFH then? All other things being equal-ish, given the choice I’d go for a material with a greater specific heat, accepting slowness of response to heat input in return for stable room temperature (and by implication floor temperature).

These concave mirrors are very clever. As for the cost of an indoor swimming pool, it did sound rather too good to be true.

Best at causing injuries for the careless, certainly. But more satisfying to use.

Guilty as discharged. Our build is less than 250m from a leisure centre with 25m pool, gym and sauna/steam room. I love the sauna and steam room, but my eco guilt bones won’t let me have my own, similarly with the pool. However the rower and the weights (with huge tv, natch) I draw the line on, despite the negative payback vs gym membership. I’ll swim in other peep’s effluvia, but I draw the line at sitting on a warm, damp, rower seat. Plus gyms are phasing out free weights and I’m ancient school where that’s concerned. So more power to one’s peccadilloes…

How far are you from your nearest public swimming pool?

PS the grown ups will be along soon lol

Or fit one of those pump things so you can swim against a flow and live even longer. Marvellous. But say three Hail Marys every day and pay for two forests to be planted.

It appears likely that the inverter is tripping out as it believes the local mains voltage is too high. Before they start dismantling anything it might be worth getting them to check that the actual voltage at the inverter is close to the voltage reported on the app. If the fault is the voltage sensor then it’ll identify which bit to swap out. Good news is that you know how to check operation now.

The picture even shows it set to the setting you will need. But please be careful. Or, [good idea alert!] having identified that your inverter is not operating correctly you can get the company in to honour their warranty (but a meter is a useful thing to have around).

The key question is whether peeps would buy them and at what price. When I grew up peeps talked about the Jerry built prefabs being awful. (You know the post ww2 quick and cheap homes, of which a remarkable number still survive, but were still vilified). Add to that the prefab section concrete houses that lots of local authorities had to buy back because they were awful. Plus lenders and insurers not taking to any of the ‘foreign muck’. Oh and the leasehold scandal too. We have a culture with a hardened perception that the building industry does bad stuff.

I shall try and look up the specific heat capacity. I like the idea of heating during bursts of cheap rate lecky, so that’s also important to me. And thank you for the info.

Good plan. If the quotes come in ok what’s the upsides of a liquid screed if one does have the depth for either?

Just out of interest which warranty co. did you go for (we are going to be choosing in the next month)?

What are the downsides of a liquid screed? Cost? Cracking?

Umm, why won’t the fitting be easy?

Wow. Do the doors sound like the doors on the USS Enterprise? (Being serious I’m with @Mike on this one, running a positive pressure sounds like an invitation to trouble, and running balanced should keep smells out just as well - all down to the quality of the extra carbon filter you may have fitted).

So for stuffing in a frame mineral wool is the winner! Woo hoo.

Ok, just googled knauf frametherm 035 and that is a lot cheaper than the nyrock. Is there a downside? Are there other products I should also look at? Will it save me enough to pay for my part Oh stuff? :-0
