Glazing

Em-Vent GL continuous smoke vents are available in double or triple glazed glass.  The thickness and type of the glass is determined by the size and configuration of the rooflight unit.  Special requirements can normally be accommodated.  The standard specification for these rooflights is double glazed glass with 4mm, 6mm or 8mm thick glass panes, depending on the size of the unit, and a 16mm argon-filled cavity.  This ensures the Em-Vent GL continuous smoke vents provide significant thermal insulation, sound reduction also give excellent protection from traffic or other noise.  Many additional finishing options are available for this flat rooflight such as solar control and self-cleaning glass
