  1. Have a look at https://www.jamesjones.co.uk/interactive-span-table and go for a joist size / spacing where the deflection is less than 8.00.
  2. Most floors are designed to have a maximum 12mm or 0.003 x span (whichever is least) deflection limit. If you specify that you require maximum 8mm or 0.002 x span (whichever is least) deflection there will be no issues with bouncy floors and the cost difference is fairly small.
  3. For they type of window you have you will be able to render up to the frame externally and plaster internally. You could also run a bead of sealant round. I cannot see the need for Compriband.
  4. I have used Compriband as an external seal between the frame and the finished external fabric. It is fine with brick and stone but if you are going to render, the render needs to be applied into the reveal before the window is installed. It does not look as if you have enough room for render and Compriband.
  5. We used full height glazing to the stairs in this open plan room and another stair / landing which works OK. Like @Russell griffiths said, safety glass and this was also laminated for fall protection.
  6. Are you going to reinstate the conservatory? I rather like the stained glass panels and hope they can be retained / re-used.
  7. Never seen these before. Does it do 160mm as well as 110mm?
  8. Either size will be available. You may be best looking at doors designed to serve as front doors to flats. I have used Ahmarra in the past and found them to be good.
  9. I used to work in IT software development. The best projects for me were those that got canned as there were no users to criticise what I had done!
  10. The last job worked out about £37 per metre floor area but they were not great. Excluded cranes, scaffold etc.
  11. @laurenco if you do go down the crush-on-site concrete route I would be really interested in how it works out in terms of time, costs, dust and noise etc as I have been put off in the past. The build we have just done is town centre and it would not have been possible but I would consider it in the future.
  12. I think if you are dealing with a main contractor it would be better to have the architect as contract administrator. Will they also act on your behalf as Client under CDM? If you are going down the main contractor route it important that you are left with as little financial risk as possible.
  13. I have used temporary downpipes to stop the walls getting soaked.
  14. Don't think about crushing on site as the dust and noise will be unacceptable.
  15. There is no general rule for demo contracts and it depends what was agreed. I would normally expect the structure to be demolished and removed from site. Slab and foundations would be an extra. If the concrete is in a pile it may be fairly inexpensive to dispose of. Is the machine still on site? Have you got quotes to complete the work?
  16. I have used Fermacell in the past and found it very expensive and difficult to cut. Last job we used Knauf Soundshield Plus plasterboard. Very tough, good sound and fire resistance, holds a screw OK and is not bad value. We used this on a conversion and achieved v. good sound test results.
  17. So far I think that @Polly has made a decent fist of representing her firm's product, albeit with a lack of evidence on how it actually works.
  18. @laurenco needs to bear in mind that with the Velfac system the moving outer sash and the fixed inner frame are the same size which means that to structural opening needs to be larger than normal.
  19. You will need some detail drawings of the jambs, cill and head. This will show the location of the window in the frame, air sealing, any additional insulation, battening, cement board, render and plasterboard. Quite often with the Velfac windows you will need to order cill packers and a separately ordered aluminium cill screws into this. You need to allow for this in the structural opening. You should allow for 12mm either side between the window and the finished render as the sashes are the full width of the window. Have a good look at the Velfac site.
  20. Once the heating is on the insulation will allow the concrete to warm to the same temperature as the house so you won't get any condensation. Those crack may hold a bit of water from before your waterproofing was completed.
  21. Is this just the concrete drying out? Is there any insulation above? As long as the waterproof layer is OK I can't see how there is an issue.
  22. For this sort of job it is best to get 3 people over to have a look and decide what needs doing and get a written quote from each. It may be that you did not specify what you wanted and ended up with a cowboy job. What was the total contract sum and what was he supposed to do for that?
  23. Often the DPM is under concrete slab with the wall just built to DPC level.
  24. I have bought some nice looking stainless steel vents with non-return type flaps and some have gone a bit rusty.
