High CTE glass composition, and the laminated glass products formed therefrom are described. In one embodiment, the glass composition comprises a glass-forming material about 70 mol.% To about 80 mol.% Of SiO 2, from about 0 mol.% To about 8 mol.% Of Al 2 O 3, and from about 3 mol .% to about 10 mol.% of B 2 O 3 It can be included. The glass composition may further include an alkali oxide such as from about 0 mol.% To about 2 mol.% Of Na 2 O and from about 10 mol.% To about 15 mol.% Of K 2 O. Additionally, the glass composition may comprise an alkaline earth oxide of about 5 mol.% To about 6 mol.%. The alkaline earth oxide may include at least one of CaO, SrO, and BaO. However, the glass composition is substantially free of can not have MgO. The glass compositions can be used in, the laminated glass products, such as laminated glass products formed by the fusion lamination process.
