Manufactured from extruded aluminum, the 4712 High Velocity Hurricane Zone Aluminum Window series meets Miami-Dade hurricane code standards. The profile design allows for a larger viewing area and interior glazing accommodates glass replacement from inside a home. Impact windows with laminated glass and non-impact windows with insulating glass are available. A sloped sill is designed to accelerate proper water drainage away from a home’s foundation while a structural meeting rail provides stability for a secure close and protection against forced entry.
