Curtain walls

Curtain wall systems have been added as an option. To use it, a distinction is made in the external wall library between opaque walls, which are those currently in use, and the new glass walls, which are curtain walls.

Under the "Glass wall" option, users must enter the thermal properties of the glazed and opaque surface proportions (glazed ratio) of the curtain wall to be simulated, in a similar way to the definition carried out for windows.
