Hello all. we are awaiting legal completion, so excuse lack of address and details for now. It is not superstition, but experience. Highland will do for now, and it is quite big.
I am juggling my own experience in commercial projects with the more relevant experiences in your projects.
Conversion of farm steading, not new, but will be airtight and well insulated.
question 1 space and water heating.
My thoughts are to use ground or air source heating but also have oil or propane as security, and as best capital outlay value. Plus a wood burner.
I feel that most of you are going for AS with perhaps electric backup.
in commercial buildings i have specified and used AS many times, but never GS as the ground is heavy clay where we live.
AS is noisy though.
And solar panels?
I think underfloor is a given for a new floor, which we would have.
I'd love to hear your opinions.
question 2. rock wool or foam board in the walls and roof (see how I am avoiding trade names)? I was tending towards foam to keep it skinny, but I like good quality rockwool, and see it on some project photos here.
thanks
