Stressline but they're beans are always dog rough. Have an engineering brick on hand to smooth them down!

Whether that fitting could be used upside down or would it be asking for trouble. If they're made to be water tight and stand a pressure test no reason they couldn't be used upside down?

It's not just a vent there's bends and connections above. Ill see if they're bothered about having a flex seal

Will do ta

Oh no I don't mind putting a plastic branch in. It's just that the punters might think the band seals look a bit temporary. Specifically on about the fittings to join the two

Apart from flex seals / couplers is there a better looking fitting for connecting cast to PVC then back to cast. Something like a multiquick i I have to interrupt a cast iron stench pipe with a PVC 90 branch so would need 2 different fittings presumably. One to take PVC in female and one to take cast in female.

Ps well done on the art work don't show heritage England!

Water board are notorious for finding something wrong with what you've done. Or something additional for you to do. In your case I gather you already have a water supply so don't need them to approve before you connect? anyway take photos of the trench, tell him it's 4" duct and where you bring it up into house use a bit of 4" drain

If no inspection by water board then don't worry your duct size will be fine. If it's thru it's thru

Ha! Bet they'd like it the other way round then?!

I still think parish councils should lose their 106 contributions if they take you to committee and lose. Around here they take you to committee on grounds which are not even really valid. Then you get a full vote for permission at committee but delay of 2/3months.

i wouldn't worry about it if it was being covered and has reinforcement.

Theres also maximum bay sizes with certain types of concrete. The agilia mix I usually use for instance. Like you say, a neat saw cut following on from a nib or wall, or in the centre of a room looks proper, a wonky crack doesn't

Conventionally it's just there too control cracking. You might get away without if steel reinforced. I put them in at every weak point. Doorway etc. Also try and split tiled rooms with the direction you will be tiling. If theres no ufh then no reason not to put in for how long they take

Had to leave a 600x1200 section out of boarding for stairwell to be done other month. Said to plasterer, who also boarded, when you've skimmed stairwell don't forget to insulate that section before u board and skim. All other partitions had been filled with rock wool of which we had a few slabs left. Also just by chance had a piece of celotex knocking around near enough that size. What do u think the genius put in the wall?!? just shows what your dealing with

De Ja Vu, The regs state the level of sound which must not pass thru, not how you achieve it. Posi joists comply on their own in England, without need for wool in most cases. I'm all for 50mm of wool as above as this fits neatly between top/bottom chords and out the way of services. 42db from memory

nail guns to fix plastic windows. Check for spurs on their boots n all

Split blocks for cupboards if your not putting noggins in. Should at least get a fixing into two battens that way. Otherwise I usually nog at 2100 centre with 4" on flat

Makes sense if you want to sell the machine. Can't fault you. How did the repair go?

40db sound reduction was my understanding http://www.mitek.co.uk/Products/Posi-Joist/Product-Brochure/ Note how much difference the 100mm wool makes! Less than 5%

Sorry I think thats the one i used last rock wool RWA45. Seemed pretty stiff and self supporting. With regards to ceiling acoustic insulation I am pretty sure posi joists conform to english acoustic regs but not scottish regs (on their own). Although if the house was for myself i'd prefer a bit of ceiling wool aswell. 50mm would work well being the approx thickness of either I beam or Posi joist top/bottom rails.

Rs45? Look for robust details or a general spec online

Depends how much risk you want to take on without speaking to planners. Are you getting it at the right money?

By the way even National Grid are now requesting 110mm. You need to lay any smaller stuff really well with minimal bends to avoid problems. I got a bit nervous when I saw the size and stiffness of the 95NCE? which had to be pulled thru my 110mm. Lucky we had some digger tracks to wind the rope up on!
