Am I overthinking it please? Some advice on the detail of the sole plate please BH. Our detail is as below. I wonder if I need to add a strip of butyl tape (yellow highlight) around the perimeter of the house under the DCP, around the edge of the concrete? (to stop any water that does make its way under, from entering the house) some photos below of a MBC build doesn't seem to include it.

Where did you pick one up please?

Thank you all. Following up: how is best to ensure insulation stays in place during construction? Will use Rockwool RW3 60kg/m3 insulation, in 100mm/50mm/25mm depths as required. 600mm wide, 1.2m long. This is cut into 240mm/240mm/120mm strips, 1.2m long. This will nicely fit the 220mm void. (doubled up when using 120mm width strips, obviously) Shall I simply apply wood glue to the inside of the I Beam, then lay the cut Rockwool strips - and wait for it to stick?

No. Fortunately. We had always planned to finish with resin or micro cement ~3mm layer. What's your finish?

Yes. Yesterday. Garage perfect. House just about ok. Not ideal in places. Awaiting SE reply re anchors still

Literally just asked my SE this too. I'll see what they say.

The I-Beam flange depth is 210mm. If I cut in HALF 455mm NyRock® Cavity Slab 032 (or similar) 455mm / 2 = 227mm Will this friction fit nicely? Or is 17mm excess not enough for a nice friction fit?

Well done! A few days and I hope to be in a similar position.

It is. Fortunately.

Great. I thought so. I'll get rockwool slabs to fill them.

What type of insulation are you using here?

Hello all, we have cripple studs in our TF IBEAM design. My question: how best to get insulation into these? I'm don't want to reinvent the wheel, so please chime in with how it's done! The plan is for woodfibre/cellulose blown insulation in the main voids. Here is the cross section FIRST idea is to make holes either side, with an adjacent hole on the inside air tightness board, and feed the pipe through the first void into this difficult one. Fill. Repeat up the wall. SECOND idea is to fill with 100mm Rockwool in the 88mm void - As it is being constructed. The Rockwool will friction fit on one side as the second is positioned and fixed into place. Thank you!

You can create a DXF for your structure that you'd like to model in Therm, then trace it in Therm with the auto snap feature in Therm 7.8. That makes it easy. Look for "underlay" or similar in the menu

Yes this is correct. For example the corner detail: PHPP uses the external wall length. SAP uses the shorter internal dimension. Boundary conditions and Rse values differ. From memory the external conditions are 0degrees and 0.04Rse. i.e. there is no allowance given for ventilated facades. This is from memory so if anyone has a reference, please share.

Junctions picture showing all the TBs that need consideration: Appendix B had a list of all the TBs required: S10TP-05 - Treatment of thermal bridges - V1_2.pdf Corners are quite straight forward: Windows are more involved. The frame conductivity needs to be calculated and input as a custom material for the frame in the materials library. If the head/jamb/sill have different UValues then you'll need to drop it for each. Ground slab calculations are a two step process. I think they are explained in the previous ThermInstructions.pdf I uploaded above.

Think I'll be using thermo wood and applying with Eco Wood Treatment to silver it all consistently. https://ecowoodtreatment.com/ https://www.celticsustainables.co.uk/eco-wood-treatment/ Thoughts?

Appears to be niche. Which is appealing to me. Everyone on the Luxone train perhaps?

Yes indeed. Dirty big carbon filter on our intake to avoid others pollution.

Hello BH, Any experience of Velbus Automation? https://velbus.co.uk/ It seems like an easy system to understand and use for BH types - With lots of info in how it all works: https://www.velbus.co.uk/dl/training/posters/EN_Velbus_poster01.pdf https://velbus.co.uk/downloads/ Good tutorials on youtube too: https://www.youtube.com/playlist?list=PLCHw8A4D87YCm8H8JtsDbaH5waD4pEQls Would welcome thoughts and especially any direct experience.

Paul sell the Zehnder ComfoPipe Plus insulated (43mm) EPP ducting. It has 2.6x the insulation thickness and a better (lower thermal conductivity value) and is 2.5x the cost. Your choice!

Everyone has their favourite I'm sure. Batch treatment plants are general smaller than matrix but use less power than a traditional treatment plant. https://www.owlshall.co.uk/app/uploads/2022/10/Solido-Smart-Brochure.pdf https://www.owlshall.co.uk/sewage-treatment/sewage-treatment-plants/1-4-bedroom/premier-tech-rewatec-solido-smart-2-8-person/
