The VISS Fire system with a wide range of additional components, such as fire-proof anchors, stainless steel clamping sections etc. keeps the glass in the right position in the event of fire and prevents this way the entry of fire and smoke. Numerous projects and a host of international tests and approvals in classes EW30, attest the reliability of VISS Fire with respect to thermal insulation and fire protection.
