Aluminium windows fire-resistant
PE 78EI
A three-chamber construction system destined for interior and exterior fireproof partitions. NT 78 EI can be used both in single and double doors, opened outward and in inward and combined with various threshold solutions. It contains thermal separators 35 mm wide. Construction depth of the sections for frames and leaves is 78 mm. Thanks to the three-chamber construction and additional reinforcing elements, the system can serve to create large size constructions. Two types of fire-resistant infills have been used: gypsum inlays and aluminosilicate fillings. The system can be used in smoke-proof constructions.
