RVGS Lifetime Laminated (LAM) glass is tinted windshield glass consisting of two pieces of glass bonded together by a sheet of laminate. This bonded material has no spacer and therefore eliminates any opportunity for fogging or creepy seal. Each solid panel is shatterproof for added safety and security. Offered in five colors and in two different thicknesses, we can match about any framed Motorhome window out there.
