This European 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 to a window, a French window or a curtain walling in such a way that in extended and closed position they inclose an air layer of thickness roughly constant between 15 mm and 300 mm (shutters and blinds parallel to the window or to the façade).This standard applies to the following shutters and blinds :- Shutters : roller shutter, external venetien blind, wing shutter, sliding panel shutter, venetian shutter, concertina shutter, flat-closing concertina shutter ;- External blinds : vertical awning, facade awning, conservatory awning ;- Internal blinds : venetian blind, roller blind, vertical blind, pleated blind ; - Blinds incorporated into glazing.
