VS1-A FAQs
-
No size constraints. Theoretically a 10ft x 65ft glass panel (maximum glass size available); standard fittings can support glass panels up to 150sq ft; custom fittings can accommodate larger glass sizes. Up to 3” thick with standard fittings; thicker glass will require custom fittings.

VS1-G FAQs
-
59’ with no intermediary steel reinforcement. This can be done with one continuous glass fin with no splice joints needed.
-
No – as always, VS1 uses through-the-joint fittings that do not require hole drilling through the face glass. Any glass panel can be used.
-
While it is possible to do so, our standard approach for glass fins is a simple direct SSG glaze between fin and face glass.

TIMBER
VS1-T Series
The VS1-T Series builds towards a sustainable future by moving away from the market convention of timber cladding and instead letting the wood do the work. VS1-T achieves all the benefits of VS1-A with a structural glulam mullion while taking on the issue of embodied carbon in construction.

We offer two softwoods that are domestic within the US: southern yellow pine and Douglass fir. We also can source a beech hardwood from Germany that is 5x stronger than most softwood options. Other wood species can be explored if desired.
-
We typically comply with the glulam fire safety requirements outlined in an individual project specification as they tend to differ. VS1-T can be delivered with an intumescent fire retardant to resist flame spread and achieve a specified UL rating.
Can VS1-T be flipped to the exterior like the aluminum system?
Can the VS1-T mullion be shaped similarly to your aluminum mullion?
