4-6-4 Glass
A 4-6-4 glass configuration refers to a slim double glazed unit (or sealed unit) with an overall thickness of 14 mm. Made up of two 4 mm panes of glass separated by a 6 mm cavity. Widely used for its ultra-slim profile (14 mm), in heritage properties, listed buildings and traditional timber sash windows where standard thicker double glazing will not fit. Vastly improves thermal insulation and sound reduction
