Cutting Laminated Glass
Laminated glass is increasingly popular for its impact-resistance and sound-deadening qualities. Because there is a plastic core between the two layers of glass, however, there’s a trick to cutting it. Using a glass cutter, score both sides of glass. Then squirt a small amount of ethyl alcohol along the cut on one side and light it. This melts the plastic core. Then, using a pair of glass pliers, snap away the excess. Heavy gloves and safety glasses are must-wear gear for this operation.

Cut the replacement panes 1/8 in. smaller than the dimensions of the opening. Holding a glass cutter perpendicular to the pane, score both sides of the laminated glass. Safety glasses and gloves, please. Renovation 4th Edition.
Rap the ball end of the cutter lightly along both cuts till clear lines develop. Then squirt a small amount of ethyl alcohol along the cut on one side and light it. This melts the plastic core of the laminated glass. Use a pair of glass pliers to snap away the excess. Renovation 4th Edition.
