Kömmerling 70 ST Plus - a window system that combines compactness and reliability with modern energy efficiency requirements. The profile has a installation depth of 70 mm and a six-chamber structure, which ensures stable thermal insulation performance: the heat transfer coefficient Uf is about 1.15 W/m²K. In combination with double-glazed units up to 40 mm thick, the system creates a significant barrier against heat loss and maintains a comfortable microclimate indoors. This is a balanced solution that is suitable for those looking for a compact and practical profile with an optimal combination of thermal insulation, sound insulation, and strength. The system demonstrates stability in operation while remaining affordable.
Sound insulation of up to 45 dB effectively reduces the level of street noise, making the model suitable for both urban apartments and private houses. In terms of operational characteristics, the system shows resilience: air permeability - class 4, water resistance - up to E1500, wind resistance - C5. Additionally, it supports the installation of anti-burglary fittings with a protection class of RC2.
The design of 70 ST Plus is notably versatile. The narrow profile provides sufficient light transmission, while the wide choice of laminations allows for adaptation of the system to any architectural style. The construction remains easy to install and reliable for long-term operation.
