      Trade just haven't spent enough time figuring out what works well and what doesn't work well with warm roofs. They will get there, but it's early days. So good to see Robin sharing his ideas for how to do it well. The energy efficiency of the finished home is well worth the ttime spent getting the design right.

    I would class this as a Hybrid roof because you have introduced a ventilation on top of the insulation, a warm roof for me is when the finish product is fitted directly to the insulation.

    In your follow up video could you go into the cross flow ventilation to the rafter. You mentioned an over fascia vent which i imagine is purely for the counter lath. Your soffit i imagine is going to be vented on the eaves and you have a detail in the ridge to complete the ventilation down to the rafter.

    I notice you have diagonal braces to strengthen the roof. If you wanted to plasterboard the loft space, would it be safe to remove these or would it mean you need a rigid sarking? For example a layer of osb on top of the rafters before the top layer of insulation, similar to a warm flat roof construction and your gable ends?

    Hi Robin. I hope you registered the IP for the attachment for the ISC240. Then you can sell the license to Festool. Should be pretty easy to manufacture out of plastic/metal plate, but I would leave them to figure that out and just get them to pay you a license for each one sold. Easy money. Might not be as much as manufactoring it yourself but the pennies add up to pounds.

    Hi Robin, great video, been watching a few as looking at a build in future. Quick question of warm vs cold roofs - if identical 200mm total (2 x 100mm) pir was used between rafters and either above or below rafters depending on if warm/cold roof, is either better from a energy conservation standpoint. I was wondering if colder than air temps due to heat lost via radiation in night sky on exposed rafters vs covered insulated rafters alters anything or if it did wether it’s negligible. Cheers!

    Great video. We were trying to look for information or videos on warm roof construction and couldn’t find anything as comprehensive as this. In the end we went for a standard between and under rafter method due to this lack of information. However, the main things that held us back are as follows:
    Are the fixings driven in perpendicular to the roof or at a 30 or 60 degree angle?
    Once the battens are on, can they still support the weight of people walking/working on the roof?
    What was the reason for opting for insulation over and between, why not just go over the rafters only? Could there not be problems with interstitial condensation affecting the rafters?

  • @scottwood1562
    @scottwood1562 29 วันที่ผ่านมา

    Excellent insulation values, though missing a key component for the envelope, vapor diffusion. Typically in cooler climate zones vapor pressure drive is outward. The interior OSB is enough of a vapor restrictor to inhibit this outward drive. The foil faced exterior is a vapor barrier on the wrong side, inhibiting outward vapor diffusive drying. And does very little to control heat transfer. Cold climate research shows the exterior radiant barrier only reduces heat transfer by 2%, though blocks vapor on the cold side.
    More important to stop air flow with continuous membranes that are permeable and liquid water tight.

    Thanks for this detailed example, Robin, really appreciate the legwork you've done to make sense of the application spec differences. I've heard that PIR tends to shrink over time (due to things like off-gassing?). How is this accounted for in your 0.11 U value target & the design of the job? I've read about shrinkage anywhere between 1-2%.

    • @ukconstruction
      @ukconstruction  หลายเดือนก่อน

      The Use of Gapo Tape will allow for the minor shrinkage of PIR. Most boards by the time they make it onto site will have had enough time since manufacture to do any shrinkage or most of it, I have used some old stored sheets of PIR probably about 5 years old and they measured exactly 2400 by 1200 so no movement there, hope that helps

    I would be very interested in the difference between this and the Gapotape you used on the big build as we have followed that route. Theis warm roof would not have worked for our project as the roof height would have needed to be higher. I wish our builder had your eye for precision as we had to remove all of the PIR he had installed and refit it to some sort of stnadard using gapotape.

    Great video, as usual. I’d love to see Robin move more into the biobased sphere. By now we all know the benefits of phase shifting, thermal inertia, etc, that PIR lacks. And the circularity that is lacking here. With such a craftsman at work, Robs efforts would be put to better use, making better buildings. If only the designer and client and material supplier would take the same fanatical approach, it would yield so much more. Come on Rob! Expand into real green building, it’s an exiting field with so much development still going on and innovation at much higher pace than the regular building practices.

      I am always looking into this!!

    The house has a sweater. What I thought in the British climate zone, you would dry an envelope to the outside - given the exterior tight insulation, and a tight barrier material covering the interior wall, moisture is trapped.

    Beautiful work! Shame to cover it up with the plasterboard and tiles 😂
    Have a look into types of roofing underlays (LR, HR and Vapour permeable membrane which is commonly referred to as breather membrane). Will help clarify the requirements for ventilation (under membrane or under roof covering) and best way to install (onto insulation or above counterbattens). Membrane manufacturers such as Proctor have online webinars to help explain.

    Brilliant video on modern insulated homes. Some detail. Robin i see the counter batton at the ridge are staggered. So the rafter are not in the same line? As in spacings. From the front are different to the back if you understand me.

      Bang on Paul, the set up on both sides is different, that is why the lattice ridge beam works so well

      @ukconstruction thanks for the reply Robin . I understand now what you did. Brilliant video as always. I'm still waiting for the gazebo with the beautiful roof your going to cut. 👌🇮🇪

    Just thinking if you have 175mm joists, couldn't you just fit 175mm of 'Knauf Insulation Rafter Roll 32' instead of 100mm of pir between the rafters with gapotape, in both scenarios you would still have the 100mm of continuous PIR over the rafters it would just avoid the time consuming task of fitting the PIR between the rafters and you would still achieve 0.11 U value

    It would be good to see exactly how many hours labour goes in to everything including the eaves details

      I am going to do a video on the whole roof cost from wall plates to fully insulated up to the tiling and I will break that down into man days etc

      @ukconstruction that would be great, I know companies all complaining about everyone expects the best and highest quality coupled with highest performance but absolutely no customer wants to pay for it

    We used sf40 as the over insulation much thinner
