The YOV structural silicone glazed (SSG) operable vent is a thermally broken, zero-sightline window for curtainwall systems. The product accepts 1-in. insulating glass and can be field-glazed or shop-glazed into a four-sided SSG curtain wall or any two-sided vertical combination of SSG or captured systems. It can be triple-glazed and provides an integral venetian-blind option. Available in multiple configurations, including casement out or project out, many of the company’s hardware options are available, including stainless-steel hinges and bronze locking hardware, to achieve the desired look for a building. Tinted glass is recommended for the best aesthetic results.
