Title:
LAMINATED GLASS
Document Type and Number:
WIPO Patent Application WO/2019/044267
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a laminated glass which, with respect to conventional laminated glass that uses an intermediate film comprising PVB, has no less than the same rigidity and lightness, is easy to produce industrially, and has improved thermal insulation properties. This laminated glass comprises two sheets of glass and an intermediate film provided therebetween. The laminated glass has a through-thickness thermal conductivity of no more than 0.5W/(m⋅K), and the storage modulus associated with the dynamic viscoelastic properties of the intermediate film, at a temperature of 40°C and an angular frequency of 1rad/sec, is 1.0×107Pa–5.0×108Pa.
