ALT F50FR Fire resistant curtain wall

ALT F50FR — is optimal fire protection, maximum light transmission, visual lightness and excellent thermal characteristics of the system.

The system is intended for the manufacturing of structures with increased requirements for fire resistance and is based on the classical system with a minimum additional set of accessories.

Excellent thermal characteristics due to triple glazing, various levels of fire resistance, the opportunity to assemble large elements.
