scope:

This standard specifies the classification criteria of shutters and internal and external blinds in relation with their air permeability for the calculation of additional thermal resistance given by these products according to EN ISO 10077-1. This standard applies to shutters and blinds fitted with a window, a french window or a curtain walling in such a way that in extended and closed position they inclose an air layer with thickness roughly constant between 15 mm and 300 mm (shutters and blinds parallel to the window or the facade).
