  1. Aren't these only needed with an external blockwork skin? As mentioned you don't want to close the timber frame cavity else the ventilation is gone.
  2. Sorry I can't help but I would be very keen to hear your overall cost per m3 if and when you can work it out. I wanted Cellulose but could only find authorised warmcell installers with a price much higher than I could afford so it sounds like you are on the right track splitting the process.
  3. Sorry to hijack an old thread but the quote above seems pretty relevant... If tiling on glued 22mm P5 do I need to ply first and if so what thickness would you recommend? Planning on a former tray for the shower so just working out heights etc. Thanks!

    Sole plate for 300mm I-beam frame

    Two options; 300mm could be a glulam. Alternatively as mentioned split the sole plate, we have 2 x 45x95mm plates with insulation between. Gives a decent amount of timber to fit to the blockwork below and our sole plates were all pre notched showing stud locations.

    ICF and airtightness

    Very neat - Nudura is definitely on the list for potential suppliers.

    ICF and airtightness

    What forms the window opening within the ICF - timber? Presumably the concrete core is airtight enough by itself to not need any wall membranes then? It sounds ideal but as you mention I guess it depends on the chosen system.

    Block wall around timber frame

    We've done a timber frame with no brick skin for part of our build and clad it with Larch, no issues and we simply provided a deep ventilated cavity to keep the water well away from the frame.
  8. Following an afternoon of taping the VCL / airtight layer on my timber frame self build I'm thinking about things I'd do differently if we get permission on our second potential plot. The main change I had considered would be using ICF instead of timber frame but I'm curious to know what the strategy on an ICF build is in terms of airtightness. I'd be keen to avoid any membranes possible as this build has annoyed me in that respect and all the membranes and tapes really add up cost wise. I know there are alternative ways of doing a timber frame but generally speaking I imagine there are more membranes in this type of construction than ICF - please correct me If I'm wrong. Particularly interested in how internal services are run and the link between floor / wall / roof for the airtight layer in an ICF build (assuming it is done internally?). Many thanks

    Strip foundation vs insulated slab

    Our lower ground floor was the same as @PeterW @joe90. One of the simplest elements of the build and cheap with 300mm of EPS beneath. Our beam and block section is much more complicated in comparison and we've had to switch to Kooltherm 103 £££ to get a similar result for half the thickness.

    Interior Wood Cladding and Fire Regs

    Did you hear back from your BCO regarding the ply roof? Apologies if I missed the post.

    DIY stick build advice

    You could do worse than speak to Cullen timber design. They designed our frame which was then CNC cut and delivered to site with assembly instructions. Alternatively they can just do the design and structural calculations then give you a cutting list and assembly layouts. Good guys to work with.

    Corrugated Metal Roofing

    I haven't' got anything to add in terms of detailing but would just say it is very DIY'able with careful planning. I did 130m2 on our roof and a smaller lean -to section with no real dramas. I used cladco as they were local to me, no issues and helpful on the phone. The roof has cost so much less than any other option and I approached the job knowing if I made a mistake a whole sheet (4.3m long) was only £37 approx worst case so not disastrous. I also had custom flashings made with 100mm on the cladding edge to help make them less obvious. I'd be tempted to go smaller again if I started fresh. Velux also very helpful on the phone. I used @Crofter blog for inspiration in lifting / sliding the sheets onto the roof with a rope and rail system, made doing it shorthanded manageable.

    Heat pump and UFH mixing setup

    No idea at this time. I'm hoping to seek out an eBay / Gumtree cheapie but depends what pops up!
