but that's not going in a warm flat roof.

I have kingspan TR27 PIR tapered insulation stored under tarps but have noticed some moisture in the packaging....the insulation is for a warm roof. How detrimental is the moisture...are the boards moisture resistant?

Check the planning permission from when the outbuildings were converted....most councils remove all PD rights for the whole development. This leaves you requiring PP for anything you may wish to do. The openness argument really falls flat in an enclosed garden area.... even in greenbelt.

Where's the telly go....and who wants two sinks in the kids bathroom, they never clean them.

Anyone installed or had experience with Lo-Carbon Tempra/SELV de centralised systems rather than full blown MHVR in passive level property.?

Closer spacing means increasing volume of water which reduces boiler shunting on and off if gas or oil but then you fall into the issue of having a very low flow temp which is an issue if using anything else than Heat pumps

I would make sure you brace roof trusses to walls well

Building regs I believe is Height equal to no more than 16 x wall thickness so 150 block and would allow 2.4m high without pillars. At 8 x 11m I would personally build a side to side partition wall or 2 which would help stop wall spread... room for a bar etc and ready for the annex conversion as well. A friend recently bought steel frame building and Building control made him dig out padstones and make larger 1m x 1m and 600mm deep, said it was wind load on long side of building.

Because I have severe heart failure...and the job is too big to get involved in if then have to stop because my tickers playing up. I pick and choose what I know I can do or break off from for several days.

single storey building, scaffold all round. OSB boards, cut to fall insulation and VCL already on site. due to size and weather the deck and insulation need to be laid same day as can be covered by membrane, or parts of over several days. Short parapet upstand around 3 sides, after insulation parapet 360mm down to 140), fall to gutter on northern elevation. Not complicated - 2 internal and 2 external corners at the short side of parapet. they need to lay deck, vcl, insulation then membrane guys 5 days so the guy said). EPDM on standard terms (firestone) is £1800 and adhesive another £1000 + drip edge £500 - that's to the man in the street so should'nt expect and uplift above this price (they supposedly buy in bulk rolls 100m x 30m and bulk glues) so I was being very generous on the £6000 materials. The local guy was qouting £150/m2 prices to include top end membranes like TPE.

So why fanny about and not be honest...I had a local guy on monday having a look, 30 years experience with EPDM and at least he was honest saying the job was too big for him...when asked about what I should be paying he said 150/m2 tops inc all materials from anybody. unfortunately he wouldn't recommend anyone..

£650...bit of a bargain for foundations and steels

In land of coal profiteering is still thieving...just legally

TonyT, I am sorry to say the way you condone a profiteering company makes me wonder about your morality or if you run a business with the same ethics. When they have £6000 at most in materials and max of a week for maximum of 4 people in labour how can £48000 be justified. Its in Leeds not fecking Monaco!

they will still qoute on roof build up above roof joists...better finding out early if its killing your budget and before spending money on se and then changing design. I budgeted £20000 for roof before starting which at the time was more than enough, now a pitched roof would have been much cheaper had planning allowed and I could have done much of the roof myself. Covid seems to have brought the worst out in companies with regard to greed. I get the feeling they are stealing were they can.

I'd get a roof qoute first...I am having a nightmare with roofing qoutes...twice as much as shell cost in one case. I would advise anyone to go pitched planning will allow.

So further qoute has arrived...labour to install supplied osb deck, vcl and insulation (cost to me £11000) and there membrane and edge drips is £54000..so a total of £65000 for 160m2 on a 3m high building...£400/m2. Im not been unreasonable in saying they are thieving bast'ards

I dealt with Christopher Hirst email- Christopher.Hirst@orlimex.co.uk I had a qoute from another uk company that was cheap https://basalt.tech/products.html#rebar i think but came in 50- 100m rolls (33p/m)....and seemingly the roll is under a great deal of tension...maybe they would cut on site before shipping?

When you consider that teplo charge £3.75 + vat and I needed 700 it was well worth a few hours of boredom

ahh.. theres the crux. The basalt wall ties are the same as rebar, supplied mainly from Russia or china...Companies buy it in 500m rolls and chop it up to length, stick an o ring in the middle, oh and new design has some bungs on the ends so you dont poke your eyes out but are generally removed on installation. I bought the 7mm rebar from orlimex.co.uk which came in manageable lengths of 2.5m at £1.20 a length-possibly gone up now. bought a bag of o rings of Ebay, chopped up the basalt to length and rolled the washer on. No they are not BBA certified but Structural engineer checked and signed them off as suitable.

As Tony T says. I presume your hot water is indirect on the tank. If indirect the hot water main will never get legionella.

Basalt wall ties cost me 25p each...a damn site cheaper than stainless...still have a load of 365mm ones left over...brain fade after all the design and planning!

seemingly the vacuum glazing from some manufacturers is down to .3

Anyone experience of Gowercroft windows or windows with vacuum glazing?

Did you have to get planning permission?
