VS1 SIGNATURE DETAILS

Sloping Sill & Head conditions

VS1 is a stick-built system and our mullions can be cut to any length, thereby accommodating sloping head and sill conditions. The absence of horizontal metal in VS1 curtain walls allows for such sloping conditions to be achieved with a high level of transparency.

LESS METAL, MORE DAYLIGHT

VS1 reduces metal framing by 50% by eliminating horizontals from the facade solution. The VS1 approach to curtain walls employs silicone at the sill, head, and glass joints, dramatically increasing transparency while reducing cost.

Vanishing Sills

VS1 facades can create an a jewel box aesthetic for lobby and street-level scopes by removing the metal at the sill. The result is the glass in its purest form, connecting the indoors and outside world in an unprecedented way.
