Windows ALU Cold
The mullion and transom PF 152 curtain wall system with fireproofing. It was tested for fire resistance of curtain walls in the full configuration. During the tests, it was heated from outside and inside, and as a result, it was classified as EI 60 and EI 30. The system can be used in curtain walls with glazed or non-transparent inter-storey strips. For the translucent strips, one can use single or multiple fireproof EI 30 or EI 60 glass sheets provided by most producers on the market. During a fire, the construction retains its carrying capacity thanks to interior reinforcing aluminium section with fire-resistant infills and special transom-mullion connectors. Thermal separators are protected by swellable tapes, which also seal connections between the construction and the glazing or non-transparent panels. As a result, the structure is fireproof and insulated. It is also possible to create a facade construction with fireproof doors, both single and double-leaf.
