Vistabrik Fire-rated glass blocks for commercial windows and partition walls

    • Increased fire resistance

      If you own a cluster home in a limited lot residential community, your building codes can require windows with fire 60 or 90 minute fire ratings. Additionally, fire-rated windows are often required in non-residential construction (for example, in stairwells in schools, hospitals, parking garages, etc.). Whether you choose the solid vistabrik glass blocks or the 60 or 90 minute units, you’ll be secure knowing you have the maximum protection vs. fires in adjoining units.

      City dwellers or homeowners on busy streets will find glass block windows significantly reduce noise levels from traffic, etc., and provide a quieter space. The solid 3” thick Vistabrik  has a sound transmission class (STC) rating of 53, while the 60- and 90-minute units have an STC rating of 48. (The average STC rating for a double-pane window is 28, in comparison.)
