I have to redo the roof of my veranda I propose the pose of isotoit ast / ast comfort with the installation of a skylight at the top of the roof. is a good solution for acoustic problems and heating.
For me, a veranda is entirely glazed... When it has an opaque roof it becomes an extension of the house... with glass walls. In these conditions the Isotoit AST panel seems to me a priori a good solution if we look at the thermal and acoustic characteristics of this kind of sandwich panel based on PE foam. The skylight is only interesting if the glass walls are limited, otherwise it is better to create indirect lighting.
