A rule of thumb for PB weight and thickness is 400 centres 12.5 boards 600 15 mil boards MF 1200 grid = single layer PB 800 grid = 2 layers of anything Not a Google technical answer But a rough guide

👏

10-15 is perfect

Yeah I bought a handful off a guy on eBay West Midlands

Clean shaven for 3M according to HSE Though my lad has a spray shop and that’s all he uses

Most of the sites insist on us using these for cutting and mixing plaster Rechargeable Charge lasts for months Pick them up for about £150

Isn’t google a wonderful thing 😁

It all does the same job Though it’s worth using 600 mil high load dpc on the GF to attach to the screed membrane

I’m doing the plastering framing on a large self build The Ground-worker has just Paid 80k for two 13 tone machines He reckons the industry is a wash with plant Due to government free money over lockdown One of the machines I had on loan was bought with the free cash When it’s not here it’s sat in his yard doing nothing Great time to buy

I’ve been doing fire protection quotes for 25 plus years If you follow my original answer Two story No extra fire protection needed Three story Extra needed You won’t go far wrong There only houses Commercial projects are much more complex If your steels need protection It would 100% be marked on the SE drawing Even the size of the pad stones are on there

We had solar blinds at our previous build The boxes arnt that big Two of our five boxes failed after 12 months I wouldn’t have fancied digging them out of the masonry

You can do But you don’t need to 30 minutes standard plasterboard if fine BC don’t always No the regs

I do fireproofing as part of my business We are never asked for any protection for two story homes But once that extra floor is added You will need an hour protection Some insist on the beams being wrapped Then boarded Others are happy to treat them like an integral garage Two layers of fire line board It should really be on the drawing Our last two builds are full of steels supporting the floors No protection needed This is our current build Note no mention of unnecessary fire protection from the SE

If it’s two story the steels don’t need to be fire protected

SBR 3-1 with dry cement mixed in with a drill to a yoghurt thickness

Presuming your over three floors If BC is asking for an hour fire protection You will be ok to just use a single layer of fire check Don’t forget to seal around the perimeter of the room

I love all this I saw an old clip with John Noaks Predictions for the year 2000 No car Just mono rails Both presenter where dressed in space age clobber

Regardless of all the sales talk The figures don’t add up We where quoted 11 k with an a saving of around £200-250 per year The buyers of our first build have have covered my beautiful slate roof with PV not a great look Considering our build came under Heritage and we had to match everything to the 500 year old farm Even the chimney pots 17k including two batteries No heat pump yet The salesman has promised a saving of £500 per year Even if the PV wipes out the £960 per year that we were paying Your still 20 years to recoupe the cost That’s if you haven’t replaced one or both the batteries That Mr google says have a lifespan of 12-15 years At least the salesman didn’t promise a break even in 3.9 years 😁

If you are putting PV to save the planet Get at least one battery and as many panels as possible If you are looking to save money Forget the PV As it will take Decades to pay for itself Or buy cheap and self install

Exactly Its a large fan

Our Mitsubishi eco Was very quiet when first installed You couldn’t hear it from 3 meters away After about a month You can hear the fan from about 10 meters away

Grand for the plumber 200 for the ground worker

Todays job All plasterboard and tanked They have paid 270 m2 for just the tiles

Why not just use plasterboard and tank the joints The majority of my jobs are PB Even wet rooms
