Curved particions?

lomb

anyone know what a curved one costs, ive found out a straight partition is 60 euro +vat per m2.
how does it affect a suspended celing also? can a suspended ceiling be curved around it?

rooferPete

Hi lomb,

Industrial (metal) or domestic (timber) ? I would expect a multiple of three as a guide depending on the size and how sharp the curve is.

For industrial and commercial glass bricks with a real brick base are often used for that detail.

Curving the ceiling should not be a problem, a little more expensive because of the extra time and waste, again it depends on how sharp the curve is.

hmm well its for a dental practice so basically needs to be fairly soundproof, apparently glass wool between deadens it, though i believe it needs 2 studs to seperate the sound. i might just go the straight route and use curved movable partitions as decoration, if its going to be a big job.

, 3rd picture from the last, i wantedsomething like that on a single wall length as there will be no hall if u know what i mean, but if its going to be a lot of trouble im not sure if il bother. the place is only just past the foundation stage so changes could be made yet.

Lomb,

l've seen high density polystyrene foam being used for internal features including curved walls and disguising steel colums etc, one included an ellipse shaped screen that incorporated a fish tank.The polystyrene was coated with a cement based render with a nylon/polyproplene mesh embedded in it. This gives it impact resistence and is class O fire rated. www.parex.com & www.dryvit.co.uk have some information on the coatings.

The items l have seen weren't load bearing but were an usual way to create unique shapes. It maybe easier than trying to create curved studwork.

Hi lomb,

I would be inclined to use Rockwool Rollbats where sound is an issue, they may have a better product by now, it's not so long ago we used it in a court building where privacy was a big concern.

The curves in that photo are fairly soft so shouldn't cost as much as three times the difference, a good plasterer will take any sharpness out by using bonding and then skimming.

That should help further with the sound issue, a long straight wall would lack character, since I have a phobia about that profession (see I couldn't type dentist)

I would like a comforting approach, combined with a nice colour scheme it would work great on us kids

hi rooferpete, did the rockwool work when u used it? did it deaden the sounds completely?

so are u suggesting curving polysterene over a straight wall in a semi circular shape, as u say curving a partition isnt easy. i looked at lafarge see here

http://www.lafargeplasterboard.co.uk/products/prods/curved.htm
http://www.lafargeplasterboard.co.uk/products/concepts/curved.htm

all used with a flexible metal track for the curve instead of a timber base or top and with rockwool bedween the boards on either side.

Hi lomb,

Have to be a little careful, client confidentiality because of the particular building we used "Bendy Plywood" fixed to the metal studs for extra strength, two plaster slabs joints staggered a coat of bonding and a skim coat finish.

Cost was not an object, the ply was not needed for normal works neither was the bonding if the build up hadn't been so heavy, the noise between the rooms was tested and came with zero sound transmission.

Maybe you could let most of the countries property developers know about this way of sound proofing :rolleyes:

rooferPete

Hi delly,

The important piece in that post referred to the cost, it was not an issue

I do agree with you there is no need to be able to hear the light switches being turned on next door, the amount being paid for houses and apartments in particular should include basic privacy.

Sad to say I don't see any improvements in the near future, a recent survey on a new roof showed three courses of roof tiles each side were saved on each house by the developer causing every roof to leak.

To date I have provided three surveys for the same development, each home owner has sold on the problem to another unsuspecting buyer.

They were afraid to highlight the problem because it means removing the roof covering and re tiling at the correct headlaps, the developer is building nearby using a new company, the old company was liquidated.

What annoys me is these houses have been surveyed by at least two lenders who never inspected the roofs but proceeded to give large mortgages to what are people so glad to loan approval they didn't question if they were buying good houses or not, and the developer is doing the same thing on his new houses.

.

lomb

hmm tis sad that houses and flats are built so poorly these days. i remember in our old house i could hear the neighbours next door and there tvs, and when we were talking at night theyd bang the walls and that housing estate is the MOST sought after in clondalkin.

thank god in our new house we have near total privacy caused by a 3 foot solid stone wall connecting our old cottage part of our house to a modern dormer and the neighbouring cottage is vacant, but even when it wasnt i never heard anything. those cottages are 100 years old, they certainly dont build them like they did, u cant put a price on privacy or maybe u can

are surveyors not professionally responsible for crap advice?

from my handbook , 'a little book about buying ur first home by the ebs' it says that mortage lenders do a 'valuation by a professional to c if the property will give good security for a loan-this isnt a structural survey' i think they do a brief check of the walls and the house isnt subsiding etc.

structural surveys are done by the purchaser and answer legally to the purchaser not the mortgage company or seller i think.

rooferPete

Hi lomb,

You have read the book properly the survey is basically for the lenders benefit, known in the business as "A kerbside survey", the idea is they look at the property and decide if the house can be sold to get the lenders money back if need be.

The problem is many people think because they are paying for the survey it is for their benefit, even the surveys people have done by their own surveyors are so vague and covered by disclaimers they are not worth the paper they are written on.

interesting....i never knew that thats the way it worked in practice ive only recently been looking at property and property transactions. reading books is one thing experiance is another and for most people only comes from hugh knocks.
i was talking to a guy who bought an old house in westport and as u say survey was done by the lender and he thought all was grand.
anyway when they bought it they moved the furniture and it was covering hugh cracks and apparantly the place needs 6 months of professional building work from a team of builders???
i think he was definately stroked, i dont know the ins and outs of it but from what he said to me it would be april next year before the work was complete. so the moral is NEVER trust a vendor or their estate agent or your mortgage surveyor, get a proper survey especially on an old house and if they screw it up sue them for the losses to put it right. their insurance should cover it but to be honest if u are the customer they will get it right hopefully first time.

really ? is that true?

rooferPete

Hi lomb,

Any further detail will have to be by PM for obvious reasons, but yes I stand over the above statement, the disclaimer list can often run to half an A4 page.

The most blatent I read was each paragraph suggesting further investigation even where the problems were so obvious if the report had been clearer the buyers would not have purchased the house, in fact no buyer who would have paid the asking price.

A good survey even verbal would have pointed out the property needed in the order of €100,000.00 in repairs.

hmm, seems like everyone is getting caught up in these high inflation times and saying 'ahh its grand ul make money on it' no one stops to look at the product.

can u tell me out of interest are most of the old period houses around ranelagh and rathmines like orwell park are they in a very bad state even today after lots of money has been spent on them,i cant afford one of course but ive just been thinking thinking why they are so so sought after. i mean a 3000 sq foot house around orwell park is 4 million euro, my father was going to buy one back in 89 and bid at a few auction i think they were 90000 back then. unfortunately mum was never interested in living in a run down house even if it was that close to town and in a very good location as orwell park.

my question i guess is are they any good structurally?

rooferPete

Hi lomb,

We restored one in that area around '88, it was bought for around 80,000 and was converted from pre 63 bedsits back to a family home.

At the time the customer was looked on as a little crazy, I bet today he is the one
structurally I would take any property built in that era over today's hi tech construction.

For a while in the 70's there were houses built that had the "Cheap" lable on them, some were poor quality but most problems have been addressed long ago.

If buying today I would have some concerns for properties built in the early 90's and be extremely careful of anything built since 97.

As for today I know of houses on the market built in the last two years that will sell at high numbers but realistic values are half the selling prices because of the hidden faults.

One in particular I would recommend demolition and start again even the foundations, the reason the house is being sold is because the owner (semi self build) knows the house is in a bad way.

The same house would have been better as a self build, it was a cowboy builder who took the shortcuts not the home owners, they were badly advised.

That said there should be no way that house should be sold, I know I couldn't sell it but then I may have a touch of old time honesty that appears to have disappeared.

The problem is whether you want a perfect mathematical curve or if you will tolerate facets (think 10p coin v 50p coin). The more perfect the curve, the more you will pay.

I do not recommend recesses in the curves, but one way to do the edging is to use plastic edging, not the usual stainless steel / glavanised. Use plywood / two layers of the thinnest plasterboard you can get to do the curves. My opinion is the curves are not worth it.

You loose floor space to the curves.

As a dentist, do you want the straightness of your work advertised by a wobbly curve? :eek:

Is that clinic a Britesmile clinic? http://www.britesmile.com/

true

thats true also but gentle curves have character and show design flair, mayb theyl make me want to go to work in the morning rather than lying in bed lol.

i cant say, but i know they do britesmile in a place just off grafton street. its in a laneway behind a large laser and skin clinic that fronts grafton street half way up the street. they have a britesmile leaflet in the window so this is how i know.

hi rooferpete,

would this solution be applicable to an exisiting semi-d room? sitting room very noisy from neighbours - wouldn't mind spending money on it if i was 99% sure it was going to work.

rooferPete

Hi,

Yes it will work, however there was a website posted in this section some time back for a company who specialise in soundproofing.

Maybe someone will remember who they are or you could surf through the contributions made, it can't be any more than six months ago.

kadman

The company you are refering to Rooferpete is,

http://www.sound-proof-me.com/

and the original thread was under " Soundproofing ", by Greebo,

Hi Kadman,

Is my memory going again ? I thought that site had more info than one page ?

A distinct lack of an address in either the Republic or N.I. doesn't exactly inspire confidence.

Perhaps depadz would be better contacting Greebo or some of the other posters who may have used their services for some feedback.

kadman

My memory must be going too, as I thought there were specs and details listed there.

Oh Rooferpete, we must be losing it altogether.
