How does the female bit create a secure fitting, if there is no olive?

I bought a thermostatic valve like the one pictured but the hot and cold inlets do not have a typical compression fitting. What I was expecting was to be able to use a standard olive and nut compression fitting to connect my water supply to , but if you look at the inlets there is no groove for...

I installed a shower tray raised up on batons and a OSB platform above a concrete floor. I recently took off the panel to find a lot of condensation underneath. I can't see any evidence of any leak. Is it possible that moisture is rising up through the concrete? It's unlikely that there is a...

On that, is it worth me cement rendering the outside? It's only a single storey small wall, and will prevent penetrating damp. Or are single skin walls meant to be left bare?

Why would interstitial damp still not come through ? Surely if moisture reaches the inner leaf it'll condensate based on whether it's hitting a warm surface, regardless of void?

So what are you saying, it's not the best method? Roof fixings are slightly different as it's a lot easier to screw directly into timber

Yes that's the mechanicl fixing method which the likes of celotex advise, but the warm baton method seems to specify that the insulation is fixed to the wall first and then batons over the top of it. Makes no sense though. See previous thread below for an example. Apparently the benefit is that...

Can someone explain this method for fixing wall insulation? I can't get my head around a)what the benefit is over IPB fixed to a baton system, and b) how batons can be fixed securely over insulation - the screws would need to be ridiculously long to get through 25mm baton + 50mm insulation +...

I have a small lean to pantry single skin brick with plaster on the inside, no render on the outside. I want to insulate the wall. I'm going to fix a baton system to the wall Does it make much difference fixing insulation between 50mm batons, as opposed to 25mm batons with insulated...

What saw would typically be used to cut through granite (or similar hardness) stone? I'm talking 6-8 inches of rock, not just worktops. Im guessing a petrol Stihl or similar for larger stuff?

The glue yes but the stuff it's stuck to will slowly deteriorate.

Glueing to solid wall without a cavity is inadvisable unless there is external render , you run the risk of penetrating damp affecting the glue, and the boards will detach

tHANK YOU VERY MUCH

Yes sort of, but i'm happy to put in 62mm insulation, but any thicker than that and it starts to become an issue. I guess what i want to know is will 62mm insulation make a big difference, or marginal? The 'real feel' of my house is that as soon as the heating goes off, you notice it starting to...

Thanks, do you mean the u value i've achieved without any wall insulation, or that would be the achieved value if i were to put 62mm PIR board on? If the latter, would 0.3 be considered decent? One thing i would say is that most new builds are unbearably hot during the summer, does this...

Why would you be given a choice? Is the objective not just to retain as much heat as possible?

I've been using various online calculators for calculating u values for wall insulation, however they seem to vary considerably and make massive assumptions. I need to decide how thick insulated plasterboard i install into some bedrooms - my property is a victorian semi detached, 2x brick skin...

What does the cavity created actually achieve? Is it to prevent cold moist air hitting the final internal wall, or to provide ventilation?

Doesn't there need to be a cavity behind?
