  1. The Keylite was 2G but appears to have the same u-values as the 3G Velux (as below) This is the blurb for the 3G Velux:
  2. I've just had a look at Keylite and see they do an Integral blind model in double glazing but that the u-values (1.0 W/mk2) is the same as the Velux Integra 3G, with costs about the same and negating the need to buy and fit blinds to the Velux model. Am I missing anything?
  3. Thanks, so effectively just a treated timber baton round the window could act as a cavity closer?
  4. Thanks. Planning on some timber cladding which I'll be DIYing, just the same practice there?
  5. Cheers - I'll see what the timeline is like for the installers (they finish by providing the external membrane but I suppose there's no reason I couldn't tape over a couple of nights before they do). I'll need to look into the DIY blowers and how to depressure the house but sounds like it's worth saving a day or two in the schedule for it.
  6. Total novice question this I'm sure but I've just came across the requirement for cavity closers. Who's responsible for fitting these, window fitters and leaving in situ for brickies or brickies pre/post laying?
  7. 140mm Kingspan Tek SIPS, 50mm Kingspan Thermowall (with foil facing), service cavity and 12.5mm plasterboard. Plan is/was to tape the joins on the kit, screw on additional insulation then tape the joins there. And potentially also to tape the joins on the external weatherproof membrane.
  8. I suppose if the tape works on the inside join then you don't need it outside. Belts and braces approach suggests to do it but there's a time and cost impact too. I've read that you don't need a VCL if you have MVHR. We're putting additional insulation in so makes sense to get the foil faced stuff and do it however. Definitely sounds like a fit and forget type job. Now go work out how much tape required!
  9. How did you get on? Tape both externally (different take needed?) and internally? Any other SIPs kitters taped their joins?
  10. Looks good and can see where you are coming from - there's an SME developer in south west Scotland that only does small developments in the local vernacular and whose sites I love but I'd take a streetscape like the one below before it: There's some custom build pilots that aim to do that but not sure how they're progressing (Igloo, now owned by Aviva, have a site in Plymouth which is the main one that I remember from looking before, where you could choose from shell designs by a panel of architects then choose from within approved palate of materials and configure however you liked internally).
  11. While that house is very ugly it's still far more interesting than an identikit volume developer house. I love the idea of having random designs, shapes and sizes in an Almere like fashion but it sounds a real pity that the development company are constraining supply in such a way that only a certain type of household can build and only a certain type of build will be possible to meet mortgage market valuation requirements.
  12. ASHP on pre-cast insulated slab (0.11 W/mK). The 'green' system is for 150mm. Think you're probably right on the costs but trying to shave costs where possible - every £296 adds up.
  13. Interesting info - so what should be used for sound insulation in posi joists then?
  14. It has "internal humidity control" if that's the same thing...
  15. Unit will be in the loft. Not really a problem getting to it. I've no idea what manual boost does it when it'd be required?
