I am in the process of designing a steel frame house and I am in two minds about the construction of the 1st floor, the ground floor I have decided to be jet floor from Hanson, and as much as I would like the 1st to be the same, its a bit more tricky with cantilevered bedrooms on the south and west elevation/s.
The I section would be around 250mm (to be confirmed) possibly 300mm, and I would like a screed 65-75mm, insulation about 100 (min), I think my aim is to reduce the floor depth, provide good insulation and protect the catilevered bits that are sticking out more, all this and I would like to reduce thermal bridging where possible,
The question is which is better concrete beam (such as jet) or timber?
Many thanks for your input

How will you insulate the house? What are your target U-values?
