VS1 Signature Detail
Toggle Fittings
VS1 has the option of incorporating toggle fittings that engage recessed channels within the IGU spacer, resulting in a flush “no exterior metal” façade aesthetic. Alternatively, we also offer the toggle fitting strategy using an aluminum cassette channel bonded to the inside surface of glass, which allows the use of standard IGUs but maintains the flush façade exterior.
