Warm Deck Dormer Roof - Is this correct?

I agree that cold decks can be advantageous in certain circumstances, but as I said generally warm decks are better. I'm only repeating what the industry is saying. Take one of the leading bodies NPS who are part of the royal institute of british architects;

'This ‘cold deck’ construction is considered problematic in the humid, temperate climate of the UK where the effective ventilation of restricted roof voids may be impractical, particularly in sheltered, built-up areas. It is universally recommended that cold deck flat roof construction should be avoided.'

I take it cyclone has lost all serious interest in this debate now!!! I don't quite think you got my humour earlier!

Nope, nor your motive which is much more suspect.
Universally recommended is vastly different from universally accepted rotfl::rotfl::rotfl:

I have never known a question poster have such arrogant views and seemingly want to perpetuate them.

But fine, make a bigger mug of yourself if you wish, I'll accomodate you

Not that you are reading this anymore because 'you're out', (but I know you are reading it haha), but as this turned into a debate (which I didn't want it to), it becomes a forum where people share views and back them up with evidence. So far I have shown warm decks are superior in most ways in general. You both have not been able to do the same for your views. Vis-à-vis, I win debate!

Cyclone, don't try and call me a mug, if anything you have demonstrated utter disrespect and downright pathetic people skills, I could call you much worse but I shouldn't lower myself.
I wanted to be all grown up about this but it did turn out to be very playground like, calling people spammers with hidden agendas.
If I had something better to do (and I wish I did right now I'm really bored!) Then I would have given this up a long time ago!

Grown up?, yeah, got ya :rotfl::rotfl::rotfl::rotfl::rotfl::rotfl:

Right, just to clear this up - at no point have I said that one is better than the other, so clearly you haven't been taking any of that in, but let me repeat:
Either type of roof has advantages and disadvantages, they can cost the same/more/less depending on the specification and detailling, they can both have problems if they are built badly/incorrectly.

As someone that clearly does not have the knowledge backed up with any experience I would question whether you are the best person to advise on construction details, this is reinforced by the fact you have had to ask on an internet forum if your own roof construction is built correctly - I said I was out because I have said the same thing over and over again but you are clearly an expert in roof construction details now.
I really hope that anyone reading this thread does not take your newly discovered expert opinion if they are considering and instead looks for the most appropriate solution for their own situation.

this thread seems to have got out of hand but interesting all the same. I wholly disagree though about everyone builds warm decks when building our loft no one mentioned warm deck to me everyone i spoke to suggested cold deck? BI's never said anything, guys that built ours and my mates company only does cold deck roofs and hes sold literally hundreds of these things. I asked earlier how BI are meant to inspect a warm deck construction? Most wont even go near a ladder or scaffold! Are they supposed to know the ins and outs of both designs? I doubt it. Bit like everything when we were building ours. There was never a best way and theres always someone telling you different. Time will tell i suppose but i wish there was better info on what should or shouldnt be done. Warm deck would have saved me hours of cutting and stuffing the stuff into all the joists! I was under the assumption taht this was the standard way? fortunately im not going to lose any sleep over it. I cant remember what you asked initially but i hope you get it sorted.

I have to admit, this is all very amusing now! I was quite frustrated beforehand but now it does bring a smile to my face!

Grown up?, yeah, got ya

Pot kettle black?!

Neither can andy

And again, along with many other times! Thanks Cyclone for you mature input! I suppose I can't really complain, but at least I had a slightly more entertaining side to my jibes! I give as good as I get.

Hopefully this post will end all of it.

To join you sole, I certainly never meant at any time that any one choice is better than the other in all situations. And yes some are more suited to others. So I'm sure there are many examples when cold is better than warm!

This was never really my own opinion, rather than everyone else's who is in the industry. Of course I will agree with them if that is the consensus. So it's not me you want to have a go at really! I'm just repeating what they're saying! I will be the first to admit that I'm not an expert in this industry, but they are, and they all agree! Are you an expert in this field? (Kind of rhetorical)

And to highlight your point about people looking at this thread and taking away information from it, I really do hope they take some professional advice, and all the advice I have found so far are unanimous in their ideas. I didn't want people thinking straight away that cold was an equal contender is most situations when so many bodies and advice out there point to warm. It would be interesting to see the statistics of warm and cold decks, but I have an idea that warm is becoming much more popular, especially in the loft conversion area.

I'm not here to give advice (I originally asked for something quite different), but as I said I feel compelled when there is clear information available from official bodies who push warm rather than cold in situations which allow them.

I think our disagreements were mainly about what you should choose in all situations, I certainly didn't mean choose warm at all times. Its all relative! I was just pointing out that everyone who I've spoken to (and that's a lot recently! In depth convos) and all the literature from trade bodies etc, have concluded the same thing in general terms.

Hopefully we agree on that!

Now, does anyone need a warm deck roof? I know a guy.....

You have said "generally" several times, that means you are recommending one for most situations, what my point is is that there is no "generally" each should be judged on the specific situation/requirements.
You have been taking advice about your specific application...
Whilst I might not be a roofing expert or a salesman for a roofing company, I have designed and detailed a good few roofs in my time (and carry the appropriate insurance to do so) and I recognise that a "one size fits all" approach to building details can land you with more problems than its worth
