Heating pipes are under shower waste pipe, and slightly touching, can this be future problem

Hi, got some Abacus tile backer boards for my shower, floors and masonry plastered walls, what adhesive could i use to fix them, there own KST adhesive is quite expensive, wounder what else could i use?

Hi, been given away some knauf rainscreen slabs, i know they are for façade systems. but can it be used inside, like between floors for sound insulation ?

thanks

Can i seal all gaps in old floorboards on first floor, with Rockwool Acoustic Intumescent Sealant, before laying new engineering floors, i got few boxes of that stuff, wondering is it flexible for any movement.

can i put some new joists under the rafters like in picture, because the way some of the old joists overlap each other that I can't atach the new joists on normal side only the rafters side, the engineer said is not recommended, but don't really know how to do it differently. i could ask engineer a gain but it takes 2 days to get answer.

so got email from engineer to double them with 2x6, and change binder to 2x6. Could you explain me how is " SPLICE THE CONNECTIONS WITH 1 METRE MIN SPLICED TIMBER SECTIONS" looks like.

? no, i got a lot 2x3, so was thinking to use 2x4 , where struts is pushing ceilings and in other places somehow use 2x3, if not will get more 2x4 not a problem

yes in the middle

...and should i do all of them or every other?

Thanks for opinions. Will add alongside old, new 4x2 , should shim new joist on wall or put timber wallplate ?

It's a bit bowed but not a lot, a lot house's on the street same..

ceiling is quite low in some places, and sagging is 4cm-5cm,

There is a wall, in the middle and on the ground floor there is rsj beam, where wall goes, but it looks like was there long time a go I had engineer, still waiting for calculations from him. He advised me to sister the joist.
