Abstract:
A glass laminate (100) including first and second glass layers (102,104), a reflective film (110) having opposed first and second major surfaces and disposed between the first and second glass layers (102,104) with the first and second major surfaces facing the respective first and second glass layers (102,104), a first adhesive layer (117) disposed between and bonding together the first glass layer (102) and the reflective film (110), and a second adhesive layer (119) disposed between and bonding together the second glass layer (104) and the reflective film (110) is described. The second adhesive layer (119) is thicker than the first adhesive layer (117) such that the first major surface of the reflective film (110) is separated from an outermost major surface of the first glass layer (102) by distance d1, the second major surface of the reflective film (110) is separated from an outermost major surface of the second glass layer (104) by a distance d2, and 0.05
