Thanks for your quick reply. I will go for it as you suggest.

Hi, I'm doing a loft conversion, and have just put the pink fireline plasterboard across my new 1st floor ceiling. Building control are asking for intumescent mastic in any gaps between boards. There's quite a lot of gaps, typically up to about 7mm wide, both in the plane of the ceiling and...

Thanks, that helped. I have found lots of info under structural clay tile prisms. I think BS5628-1 table 2c is relevant for compressive strength (using the Bennet article below for typical unit strengths). useful links: Bennet "COMPRESSIVE PROPERTIES OF STRUCTURAL CLAY TILE PRISMS"...

Thanks, noseall. How did you get around this? Perhaps with an extended length of bearing?

Hi, The gable end of my 1930/40s brick house has these strange bricks/blocks (picture attached) on the inner leaf. They seem to be made of clay like conventional bricks. I have been googling images but find nothing comparable. Does anyone know what they are called so that I can research them...

A final update. I ended up using Rockfloor thermal rather than RW5. The rockfloor data sheet I was sent showed it to have a much higher compressive strength : "...A gradual breakdown of the structure does however begin at approximately 40kN/m2" On talking to the screedboard manufacturer...

Thank you both. Yes, I see what you mean about the possibility of flexure at joints (the screedboard20 does indeed have a clicking tongue and groove, not sure how much stiffness this adds). Bobsuerita - It's good to hear that it has been used extensively - your message gives me some...

Thanks, Dan and fixitflav. It may well be against dry-firing the heat source, but as you say most heat-sources have their own protection to guard them once this condition arises. To me it would seem the lesser of two evils to allow a dry firing vs a pressurised vessel exploding though. On more...

Hi, I'm planning to install a thermal buffer store (to prevent my combi cycling) as part of my UFH on a building control ticket. I'm a professional engineer, and feel competent to install it safely. However, I am unclear about part of the G3 requirements (so competency not quite there, but...

Hi, I'm a new member here, but have been floating in the background for quite a while now. I'm putting acoustic insulation and UFH into the floor of my first floor flat. I'm planning an approach inspired by an (acoustic) detail mentioned in building regulations document E, 3.102, which...
