Robin Clevett has a Lindab guttering install video on Skill Builder. If you fall down the rabbit hole far enough, you can find Lindab documentation that informs that you can use a metal chop saw for cutting the material. http://publications.lindab.com/UK/rainline-brochure/?Page=2&page=46 Even the product sheet for the downpipe mentions chop saws. https://www.lindabprofile.co.uk/wp-content/uploads/2021/06/Lindab-Downpipe-SROR-Data-Sheet.pdf Obviously a hacksaw is the simplest method. They also have touch-up paint for the cut edges and drill holes, how necessary this is, is anyone’s guess.

One of the YouTuber’s I follow, actually posted a pitched warm roof video today.

@Mattg4321, thank you for reporting back with your update. It is so important people do this. I’m glad you found a solution.

Did the weekly Legionnaires thing get mentioned yet?

There are specifics to each ICF system. With Thermohouse, you could safety order aluminium windows off plan, with a standard 10mm margin on top, bottom and sides to the rough opening as you would do with a replacement window. With Thermohouse, they have a specific check reveal block for windows and doors. The rough opening is EPS on all four sides. You could very easily rasp back the EPS by 5mm, if the windows don’t quite fit. With Thermohouse they want all the measurements to be divisible by 150mm, to help with the cuts, not happening where the flanges are. This also helps ensure they follow the plan.

This is a very good video by Robin Clevett on 2024 BR Warm Roof install. Might be a bit OTT for you requirements.

@JamesPa, that was my reaction when I watched an Urban Plumber YouTube video, hand waving away the need for insulation under a slab. This guy is a Heat Geek certified installer, even done a few videos with head Geek Adam. Reading the YouTube comments it appeared I was wrong and that the ground actually works as a thermal store! You just need to be wary of high water table and underground water courses, that will remove heat more quickly. For clarification, I would personally advocate for an insulated raft foundation.

@richo106, I have not been following this thread, but I feel your pain now that the cold winter weather has arrived. I’m not familiar with this approach or the design trade offs. I have no special knowledge about UFH installs. Just another amateur forum member. This blog advocates against using aluminium spreader plates with ASHP. They say it will need flow temp as high as 55°C, not 35°C. https://underfloorheating1.co.uk/blog/article/Water_Underfloor_Heating_and_Aluminium_Spreader_Plates?srsltid=AfmBOoositKuZ1fOjlxZgV8ygJwVgrd35zIhyDGKj6mPuA0uxoPp7vSo The approach they advocate, might be a possible retro fit. But still a lot of work. https://underfloorheating1.co.uk/blog/article/Can_I_have_underfloor_heating_with_joisted_floors?srsltid=AfmBOopQsQvvgP2zHQn6UMCldTzV5P6j8MawfYv3Le-SGh1CHtie8wYo

ICF can be quick. Our Thermohouse crew of three guys assembled the ground floor walls in 4 days, then spent 4 days bracing and erecting the scaffold platform, then poured the walls on the Friday of the second week. So 10 working days from blank foundation to poured concrete ground floor walls.

Earlier thread on same topic, which didn’t really reach any conclusions. 5mm mesh seems like a better size, but if Zehnder and Lindab both use 10mm, there must be a good reason. Some expensive options from this company. https://www.expandedmetalcompany.com/applications/filtration/air-filtration

I actually think the ones in my picture and link are galvanised steel. Looking at our flashing schedule they called it “Trocal Metal” https://grc.sika.com/dam/dms/gr01/3/010945011000000001_Sika_Trocal_Metal_Sheet_Type_S_eng.pdf I’m not sure why I thought they were aluminium. So ours are galvanised steel too.

“Sika Sarnafil Single Ply Trims” appears to be the magic words. https://cwgsheetmetal.co.uk/roof-flashings-edging-trims/#3 USA website here with lots of detail pictures, which give an idea. https://www.hickmanedgesystems.com/brands/sika-roofing Good video showing how membrane and trims are fitted. https://youtu.be/V7zutZU_Jwc?si=SPFDU7ByOXvNTPGI

@Mulberry View, not the exact same finish requirements, but here are some pictures of how they did our flat roof. Aluminium trims are fitted at the same time as the Sika membrane. The bespoke Aluminium Trim appears to be riveted to the Sika membrane. Then another strip of membrane is glued over the top. Hard to tell, but from left to right it goes: slate tile, lead, aluminium, membrane strip, membrane. For your detail, you would have a bespoke piece of aluminium to cover the curb.

I find these websites are quite good for colour matching. https://www.colorxs.com/color/bs-18-b-29-blue https://www.e-paint.co.uk/colour-alternatives.asp?cRange=BS+4800/5252&cRef=18+B+29&cDescription=Raven
