Hello.
We live in Hampshire and have just been granted PP after 18 months! I have been reading many building blogs and have found the information invaluable. We are thinking of building using MBC and 2/3 of the roof area will be flat. At an Environmental Workshop, the aim of which was to ensure that the house does not overheat, it was suggested that we would need to install a green roof to prevent overheating. The thinking being that the green roof will provide shading and the aggregate an amount of thermal mass. Does any body out there have experience of controlling heat gain through a flat roof? Is a green roof the only option to control temp gain?
Many thanks
