  1. An architect I know who specifies this says that the insects don't like the strong ventilation and won't hang around.
  2. Ipe is fairly fire resistant too.
  3. For membrane, try https://www.roofingsuperstore.co.uk/product/dupont-tyvek-uv-facade-50m-x-15m-roll.html It has BBA cert for open cladding.
  4. I once had to have some timber cladding treated and the only treatment that BC would accept was pressure impregnated - not surface applied. This had to be factory applied and the only product / supplier was called NON-COM. It cost a fortune and added to the cost was the transport from the sawmill to the treatment works, then to site. It tripled the price of the cladding. The elevation was 1.2m from the boundary with a field. I would have preferred to use fibre cement cladding (Marley, Hardie etc) but the planners wouldn't have it.
  5. £35 per metre in Brighton area Sussex
  6. I am currently paying £35 per metre
  7. I think the rule of thumb is 40 times the diameter of the wire for lap. On some slabs we have used separate lap bars to join fabric which is just butted. This helps stop the mesh layer getting too thick.
  8. I would rather just sell up and move than have one. If you have a basement, look at a small pump station which can handle solids. Quieter and more reliable, but need to be sunk down.
  9. I would stop work on the building and ask MBC to come up with proposals to remedy this. If you leave it it will impact on loads of things further down the line - furniture, stairs, plasterboard, tiling etc. You have a new house, not a Tudor cottage. Make sure you have their insurance details as you may need to put them on notice.
  10. The timber frame soleplate MUST go in completely level, packing under if required. Generally packing up to 20mm is OK and after this you would need an engineer to show that it is acceptable. Gaps under the sole plate should be filled with non-shrink grout. Packing between floor zones is a no-no. So is 30mm in 4m. Is it out of square on plan or just elevation? Pretty crap either way.
  11. Maybe different gas - krypton or xenon may perform better.
  12. Looks fantastic. Can you get rid of the kids toys or have them sprayed grey (the toys, not the kids)?
  13. I am not sure if this applies to a listed building but it is possible to construct a number of outbuildings as permitted development, up to half the footprint of the house, giving you the storage you want. If you later wanted to consolidate these the planners may be amenable. You need to be outside a conservation area for this to apply.
  14. I have used their full fill masonry insulation product CF5000 which I think is the same stuff (glass fibre layers & textured alu foil) but 450 x 1200 sheets and profiled edges. I think anything 5000 is the same basic stuff.
  15. FR5000 and RS5000 are identical. The RS5000 is marketed for rainscreen cladding and has been "tested to meet the performance criteria set out in BR 135 for rainscreen clading systems." Both have better fire resistance than the standard PIR. They also have thicker texture aluminium facings.
  16. Both RS5000 and FR5000 are PIR and seem to have identical properties. Both claim " Class O fire performance". I suspect they are identical.
  17. Come in at the side of a 5 inlet chamber and use an 11deg or adjustable to make up the difference
  18. A lot of the premium slates need less sorting and have less wastage. Those from a reputable supplier with a long guarantee will be more expensive but better. You will need to try v. hard to find anything that will fail within 30 years. Lots will last 100+.
  19. I would reapply for the lapsed scheme. When (if) this is granted, go in with your new multi unit scheme.
  20. Self build is normally detached houses which is less than 2% of homes in London. I doubt any plot would be less than £850,000. First time buyer in London = 1 bed flat or studio.
  21. MVHR. Will really help with your SAP calcs too and far better air quality than trickle vents.
  22. Where we are the tackers are just finishing installing 1000 sheets of Soundshield plus on the walls @ 37kg a sheet.
  23. I think the 50mm is sensible and allows for insulation being uneven and the roof nails not penetrating the outer airtight membrane. Why not batten the tile section an extra 25mm?
