Using Commercial Insulated Panels for Roofing on Passive House?

Seeing that it's a bungalow are you sure that the actual roof cladding has to be an insulated panel ? I'm not familiar with the details of passive house insulation requirements, but would, say, 600mm in attic be sufficient with a single skin roof panel or tile/slate on breather membrane ? If you have to fit insulated panels check out Kingspan's products, they're based in Cavan and do a wide selection of profiles and thicknesses from 30mm to 250mm - quality is good but not cheap. My advice would be to go with natural slate if budget allows or else Thrutone Slate or similar, not just because it's more aesthetically appealing but it's life span is at least 4 times that of cladding. I live next door to a house that was built over 140 years ago, has a natural slate roof, it's still good as new and looks splendid. Cladding is for commercial, industrial, farm buildings don't let anyone convince you otherwise.

There is no real benefit to going with the insulated panel in this instance. If its a bungalow go with mineral wool or similar at ceiling joist level and then use 0.7mm colour coat galvanised single skin sheeting with the KS1000RW profile, there is actually 1000s of different profiles if your willing to buy out of the UK.

They do use it domestically in germany though. I'm very tempted .....

Typical American terminology and by the looks of the construction type it's either in America or a Yank building in Ireland.!!!

Hello, just to clarify by rim joist, I mean the joist or band board that wraps the perimeter of the house sitting on the foundation, that caps off the ends of the floor, Joists and by carrier panel I mean, adding a rain screen system to the outside of it, which would be carried by the insulated metal panel. A girt is installed between the panel laps and a second layer of cladding is then installed onto the Girts I was hoping to find somebody with some experience or information about mounting. Imps to wood framing I have been doing architectural sheet metal for 15 years and have vast experience in multiple different panel systems. These panels are leftovers from various jobs that I have done. However, I can’t find any information about mounting them to wood obviously it isn’t recommended due to the fasteners being fatigued from expansion and contraction. These panels have been on my house for over two years now and I haven’t seen any problems. Just need to satisfy the building officials which is proving to be very difficult without any examples or literature on the subject I have installed metal cladding on countless wood buildings and it’s never been an issue also, I have installed insulated metal panels on countless buildings directly to the steel stud. Framing everything set in non-skid and butyl caulking never heard of a problem with condensation. I should also note that there is no visible windows on the house because the siding opens to expose them so there is no condensation there either

HI I'm looking to do the same with the insulated panels on the roof put the planners are pushing back and are unsure. If there is anyone out there in ireland that had this done please get in touch.

Ask your architect, the builder and the panel supplier.

If none of them have any examples/experience of this application, ask yourself whether it's a good idea for your home to be a guinea pig house.
