  1. thank you, ill have to get some start of the build pics up
  2. i was thinking of using 50mm wide x 25 is that ok ?
  3. thank you, its important as I'm butting up to an existing building and it needs to line through with it. Im planning on using STS construction board, and leave a gap at the top to ventilate it, and i guess it needs a gap anyway to allow the timber frame to shrink. ta
  4. Hi all, i been busy get my build underway, which has been a bit stressful. I have a question about battens, the construction - Timber frame, 9mm OSB vertical battens to create a ventilated cavity, 12mm render carrier board, and render on the outside. I had in my head all the time the battens to form the cavity are 38mm deep, but i have drawn all the drawings with them 25mm deep,... the question is, is a 25mm deep ventilated cavity ok behind the render carrier board, or does it have to be 38mm ? Thanks J
  5. Isn’t there a planning condition which states that it needs to be completed within 3 years ? it sound like you may be best getting and Architect to do the building regs drawings and submit an application.
  6. Hi, i have that there to reduce the cold bridging at that point, and picked the Marmox over another one that i looked at because it has a rebated joint rather than a butt joint, which i think helps lock them together better and form a better joint.
  7. What about DPC like this with a cavity try over and do away with the external lower dpc
  8. Is the orange mesh in the top coat, that looks like it barely has any cover on it ?
  9. Does the door frame overlap the cavity closer adequately, and is the gap around the frame filled with either compriband or the foam ?
  10. so for example the ground floor ceilings need to provide half hr resistance to the first floor, they need to be fire rated type
  11. So do the ceiling Mvhr valves where you have a timber floor and accommodation above need to be a fire rated type, it crossed my mine the other day that they should be, but when I was on the phone to BPC and asked, he said they don’t ? ta
  12. So i have redone the detail with a concrete slab, and it all looks much more sensible now, does away with the awkward air brick detail and it should be quicker and easier to build thanks for the suggestion. Any ideas for the facing of the exposed section of block / thermoblock, other than brick slips, its dark grey render at the moment.
  13. cheers ? yours was a bit of a nightmare, i bet that was a bit stressful. im going to look at a traditional slab, with the view to maybe adding a bit more insulation
  14. i will have a look a concrete slab or raft solution instead, i have not had any dealings with a passive slab before, is that something that has to be designed and laid by specialists ?
  15. ahh it never really crossed my mind to not have beam and block, maybe a traditional concrete slab, maybe easier, it will certainly overcome the under floor ventilation thing!
