Description

Em-Vaults™ are high quality continuous rooflights available in low rise and high rise profiles for spans up to 4.5 m. Units consist of solid or multiwall structured polycarbonate glazing and extruded aluminium sill sections, pre-formed curved glazing bars and capping profiles. On the solid glazed units the glazing is supplied in factory assembled cassettes. On the multiwall structured glazed units the glazing bars are secured to the sill section utilizing a highly effective bolt tensioning system. This eliminates the need for fixings across glazing bars and provides an exceptionally strong framework enclosing all four sides of the glazing.
