CS 77

Product catalog summary

Overview: The CS 77 is a thermally improved three-chamber system designed for windows and doors, offering an optimal blend of safety and comfort. It features fibreglass reinforced polyamide strips with ribs and/or hollow chambers for high thermal insulation. The system supports various aesthetic shapes and both inward and outward opening mechanisms, with options for different inner and outer colors.

Technical Characteristics: The system includes style variants such as Functional, Renaissance, and Hidden Vent. Key dimensions include minimum visible widths for frames and vents, overall system depth, rebate height, and glass thickness. The glazing method involves dry glazing with EPDM or neutral silicones, and thermal insulation is achieved through 32 mm omega-ribbed and/or hollow chamber-shaped fibreglass reinforced polyamide strips.

Performance:

Energy: Thermal insulation is measured by the Uf-value, ranging from 1.6 W/m²K to 2.6 W/m²K.
Comfort: Acoustic performance is rated with an Rw value of 36 (-1; -4) dB to 42 (-2; -4) dB. Air tightness is tested up to 600 Pa, and water tightness ranges from 0 Pa to 900 Pa. Wind load resistance is tested up to >2000 Pa, with deflection classes A, B, and C.
Safety: Burglar resistance is classified under WK 1, WK 2, and WK 3 according to ENV 1627 – ENV 1630 standards.

Additional Features: The system can be combined with the Ventalis system for enhanced performance.

Conclusion: The CS 77 system is designed to meet modern architectural trends while providing high levels of thermal insulation, acoustic performance, and safety. It is suitable for a variety of applications with customizable aesthetic options.
