CP 155 Aluminium Sliding Doors
CP 155 is a premium insulated sliding system offering the highest levels of performance. This sophisticated system fulfils the user’s high expectations of optimum quality, high insulation and ease of operation.
The inherent strength of this system makes it possible to offer very large dimensions – up to 3m in height and a maximum vent weight of 400 kg*. Thanks to the ‘High Insulation’ upgrade, the system can achieve superior insulation levels down to 1.07 W/m2K (Uf value). This results in a glazed element with insulation values lower than 1.0 W/m2K, allowing the CP 155-HI system, which is certified with a Minergie label, to be used in low-energy buildings.
Furthermore, the system is available with a low threshold option that creates perfect continuity between the indoor and outdoor spaces, and improves the accessibility to the building.
This accessibility and comfort can be further improved with our solutions for automatic operation.
