Plasterboard - What to use where?

Recommended Posts

Having looked over the Building Regulation plans produced by my Architect, I'm confused as to what type of plasterboard I should be used where, as the blurb on the plans doesn't go into any detail? Is there any particular Building Regulation rule I should be following, or it as simple as use 12mm throughout?

If you use 12.5 mil boards on the cielings 

All endges need to be supported 

Best to use 15 mill TP boards 

on the cielings As you can set your joists or trusses at 600 without any need for noggings 

Foil back boards to underside of trusses and any flat roofs 

With the exception of bathroom cielings 

No one does a foil  back Moister 

So bc will accept either in 15 mil to bathrooms I ideally go with moister 

Moister 12.5 boards to bathroom walls 

and personal choice for wall Soundblock etc Or just 12.5  wallboards 

Abito boards are worth looking at 

Bit pricey Allow an exstra 60% for labour 

No good for fit and dab

I was wondering, in a highly insulated new build with cathedral ceilings,  would you recommend I use foil backed plasterboard for the cathedral ceiling sections?

every skimmer I know seems to have different preferences - the chap doing our house said stick 12.5mm normal PB (SE) everywhere & he uses board finish on the lot.  Who knows whats right!

I uses standard taper edge 12mm everywhere, except bathroom the green water resistant version and garage, the 15mm pink fireline 2 layers.

 

Skimmed by my plasterer with 2 coats of multifinish.

 

All edges secured, nothing left to chance.

I can’t understand British Gypsun still selling Board finish 

Does the same job 

I buy board finish as it is 20 p a bag cheaper 

We normally buy few palettes per week Every penny counts

So yesterday I rang round about five plasterboard suppliers.

 

I need 580 (8x4) boards, so the first calls were to a large national distributor, i then called Jewsons, Buildbase, C W Berry and finally my local family owned BM. Guess what,  the local BM was cheapest,   their 12.5mm is £4.87 a sheet and the 15mm £6.10 a sheet.

 

Maybe if I should see if I can get the smaller format boards for the same price as they’ll be easier to handle.

Is it possible to buy sheets bigger than 2.4m, I do find the English sizes a bit pathetic to say the least, when are we going to catch up with the rest of the world.

I think if you catch Wickes with all their discounts lined up, and use a Reloadable Cash Card e.g. From your employer or Westfield Rewards, you may beat that by 5-10%, but you would need to wait for the day. I am not sure if they still do a standard bulk 5 for 4 type discount on plasterboard, however,

 

Consists of £7.20 base price for 8x4 12.5mm

10% off for Trade Account.

5 for 4 if they still do this, and I have not bought plasterboard recently enough to have seen it 

5% extra for Trade Customers via the newsletter e.g. There was one last week

10% off for the reloadable cash card.

 

They may have deals for the monthly offer, Half Term or Easter.

Travis Perkins do 2.7m. I had them in green, moisture resistant for the bathroom. Why you may ask?

 

Because some idiot when he put his new ceiling joists in ended up with 2470mm as a room height and didn't want silly little bits of pb at the top/bottom.

 

"He" didn't appreciate the knock on of this meant silly bits of TILE...

I seem to remember having to specify 2400 x 1200, rather than 8 x 4, as 8 x 4 = 2440 x 1220, and we needed 2400 x 1200 to match the 400mm spacing of the counter battens and studs and the 2400 room height.

more thickness to put screws in edges and unless you on std 8ft ceilings  you going to have some joints anyway  . if doing a proper finish coat it don,t matter anyway

tapered edges were made to allow just filling joints and sanding  --for cheapness .

a proper plaster job should not need any sanding when finished   if he polished it correctly

 and square edges won,t phase a REAL plasterer at all,

If you doing a near passiv self build ,why skimp on plasterboard -use 15 mm though out --will just improve sound proofing and insulation value.

you spend 10k on an insulated slab then penny pinch on plasterboard --no sense to me.

A lot of the choice is what it the standard stock in the BM.  Here it's standard metric sheets with taper edge. Anything else costs more.

 

Taper edge is indeed designed for tape and fill, but won't phase a plasterer. Mine just skimmed the tapered joints while setting out the corner beads then that was dry enough for the top coat.

 

The main drawback of 15mm is the extra weight. Okay of you have a lifter but otherwise I would only use where there is a real need.

Thinking about it I scored some blue 10'x5' sheets from site about 15 or 16mm thick some years back. I used them horizontally. Soundbloc I assume.

I have used 

2.4m

3.6m

4.8m

6.0m 

i cant understand if you have a 4m wide room we have to have a bloody join in it. 

Even in the wet rooms the cement board comes in 3m,go from floor to ceiling no joins in a 2.7m high room. 

 

And ive used  boards 1.35m wide so you can put two boards horizontal for a 2.7m ceiling.

You can get 2.5 2.7and 3000 boards To eliminate joints Or just add T bar No chance of cracking
