have i missed something?
someone mentioned 15mm board the other day...
went out to do a ceiling reskim the other day where someone else had patched up the ceiling....
they went out and got a 15mm board, sat a little proud but no problem to me so i just skimmed the ceiling flat as you do...
what bothers me is..this bloke (who's a plumber) swore blind that all ceilings now have to be 15mm...
news to me? would it be newbuild? and if so would it apply to refurb...very much doubt it...seeing as the two arent interlinked...
just wondered...all you lads on newbuild...wots the score?? sounds stupid...few years ago they went on about double boarding kitchen ceilings for fire..then they reckon board and skim is fine...had 2 building inspectors come up with conflicting spec for the same problem in garages...one says double board/stagger joints....the other (a building control god in spalding (ray davy)) says long as you skim it its fine????
wots all this 15mm shite???
 
think that plumber has been sniffing alot of glue, if all you were only aloud to use 15mm they would stop making 9mm board.. if it did apply for site work, dosnt really effect domestic work, why double up boards when they make fire boards. steaming now

Alright bigsegs I mentioned 15mm board because the builder told my client that the ceilings had to be 15mm P/B it apparently cuts out the need for noggings its a new build and it falls in with the new part E building regs not read the yet but can anyone tell me whats all of a sudden wrong with half inch board the centres are 600 as usual (well there supposed to be builder obviously cant use a F***ing tape measure)
 
thats it mate, exactly my point, the reason i queried it is cos this plumber goes on about the same s**t...now i know bein a plasterer im supposed to know this shite, and i thought i did...but unless something has changed that i missed these people are talkin shite...
small amount of doubt in my mind comes from the last time i was on a john mclean site (good 4 years ago and the last big site newbuild i was involved with) the WALLS had to be 15mm double board over with 1/2" for SOUND..nothin to do with fire..
mind boggles...
far as i know, 9.5 @ 450 ctrs. 12.5 @ 600 but everyone uses 12.5 (1/2 inch) on refurb walls/ceilings full stop UNLESS its a flat conversion then its back to sound again...which can be silly - 19mm overboard with 1/2" soundblock....
where are these people gettin there info?? your case he was tryin to cover his arse for bein a mile out with the centres, mine was a 3ft x 2ft hole in a ceiling??? it was origionally 9.5 artexed, so his 15mm sat pround??? just laid it on thick, solved the problem (which he was flappin about) but this 15mm shite? he must have paid silly money for it cos as far as i know it aint a stock item????

im not quite sure on where fire boards actually should get spec'd but the only time ive had to use em was on a big department store where we converted a storeroom into a disabled bog/baby changer (remember that big hoohaa a few years back with ramps and shite) but the gen ive had from building inspectors in the past is that to fire proof you have to double board but the second layer overlaps the joints of the first....

next thing i get told is that if you skim a garage ceiling it saves you havin to double board???
before that they used to use the asbestolux boards on a garage ceiling...\
this comes from respected sources btw...well, the guy in question is head of building control in spalding (south lincs) and really does know his shite from footings to ridge...talks like a machine gun...really got to be switched on to even listen to the guy....

I agree this builder however told the client that he uses 15mm all the time well i dropped him right in the s**t yesterday because the only place that stocks this within a 30 mile radius told me that one builder uses these boards and he takes 100 at a time and it aint the builder in question???
 
there y go...right...what i would do is find out the current regs...
many ways..
easiest way...
ring the local council number, ask for building control, ask to speak to a building inspector, have client stood next to you, put it on speaker...
should be an easy fix this one...
once through to said inspector (bear in mind that unless you ring up at 8:55 they'll be out inspectin) try after 3...just describe the job, the spec will rattle out of them (dont forget its a refurb)
another way...
try (wherever you live).council.gov or somesuch....bit of playin around will find you the part f or part g or part whatever letter the boarding reg comes under (your looking at approved document 'x') cant think...l is heat loss, only one i ca remember..
its a fookin huge document but in there you will find the legal government regulations for plasterboarding ceilings....
show it to the customer
order 1/2"
charge em for the fuckabout
another way is gen yerself up (see above) and ring said builder (without customer) play the nice guy, if he turns dickhead have a think about where the payment is coming from and adjust your loyalties accordingly...
dunno what else to say really, play it by ear, dont be had for a c'nt
 
this is assuming hes expectin you to carry the extra expense...if not just board it in 15mm and charge him, end of...
sound of it though, he's bein a dick, id be on to the builder direct, bypass the customer, come up with some bulshit fot the customer that youve found a loophole that allows you to 1/2 inch (saves the builders face) or better still let the builder do the bullshitting...seems to be good at it already, soon as he realises you know what your about he should shut his gob, all about confidence mate..but take my advice, learn from it, grow, and enjoy...were all learnin mate, thats 1/2 the fun...
moral....
if this builder realises youve got him out of a tight spot by NOT makin him look a tw"t youll get more work..
 
its now 00:47 and ive just realised that ve asked a question and then spent 1/2 an hour tellin other people how to find me th eanswer...
how p''ssed a,m I?
sorry lads..
be a plasterererere
where dya think they got the word plastered from??
 
sounds like the plumbers got the bit of board off site (tight arse). It depends on the spec and the bco who is dealing with you, it changes in different towns and is interpreted differently. Take trafford and manchester council they will differ on different things all day long youve just dont want to upset them. Job im on now ceilings are 15mill then half inch fire line, job last week 15mill sound then fireline, topfloor 15mill foilback. It goes off the spec some want acoustic mastic around both skins some dont most garages ive done are double skim fireline staggered and the first skin taped then skimmed. the skim gives you a fire time so does the first skin and second skin added together it increases. It all depends what type of building your working on ie houses, two storey or three, flats,schools, offices, prisons it all depends.
