The invention discloses building energy saving, sound insulation and heat preservation glass, which structurally comprises first layer glass, an aluminum parting strip, sealing glue, a molecular sieve, a sound insulation and heat preservation cavity, second layer glass and a low-E membrane, wherein the inner surface of the first layer glass is connected with the outer surface of the low-E membrane; the aluminum parting strip is arranged on the outer surface of the first layer glass; the molecular sieve penetrates through the outer side surface of the sound insulation and heat preservation cavity; the sound insulation and heat preservation cavity comprises a filling gas cavity, a glass glue layer, a drying layer, a spacing strip, a sound insulation and heat preservation layer and a metal membrane layer; the upper surface of the glass glue layer is connected with the bottom surface of the spacing strip; the sound insulation and heat preservation layer is vertically connected with the upper surface of the spacing strip; and the bottom surface of the metal membrane layer is connected with the upper surface of the glass glue layer and is parallel to the sound insulation and heat preservation layer. The building energy saving, sound insulation and heat preservation glass is structurally provided the sound insulation and heat preservation layer; the indoor temperature rise caused by the entering of sunlight into a room in summer is avoided; in addition, dichroic glass is used, so that during the sun irradiation, the color is darkened, and heat is absorbed; in winter, an indoor heat preservation effect can be achieved; and energy sources can also be saved.
