4F1 from Secco Sistemi is a thermal break self-supporting curtain wall with mullions and transoms. The external cover is available in four materials. The frame design of 4F1 is offered in numerous variations and integrates windows and doors to guarantee the best performance. The system performance has been tested in conformity with the standard EN 13830 regulations.
Extensive glass surfaces need greater inertia and therefore require mullions with larger sections: 4F1 gives a solution with reduced 50mm sections of structural mullions in Secco Sistemi's selection of metals and elevated moment of inertia to guarantee the required static values.
System and Performance
- The elevated elasticity modulus of the metal used in the frames guarantees a light and versatile yet still solid structure.
- Air and water-tightness are ensured by a system of EPDM gaskets realized with drainage grooves to provide run-off for any seepage.
- The 56 mm glazing panel is inserted frontally and placed on specific glass supports that are secured to the structural profiles and fixed using a steel external cover pre-drilled for screws.
- Galvanized steel
- Stainless steel
- Corten steel
