Excellent Energy Efficiency Meets Modern Design

TwinSet 8000S profiles are made of a combination of vinyl and aluminum, offering superior U-values for energy efficiency. In addition, the three sealing levels used in the construction of the profile reduce the effects of thermal bridges.

All seals are integrated into the frame, providing proper insulation of the 6-chamber system and allowing the glazing to be mounted flush with the casement frame. This has the additional benefit of ensuring a weather-proof seal to reliably stop cold air from entering the house. These ensure that the frame itself provides excellent insulation and not just the glazing. The best triple glazing can't work miracles if the frame surrounding it is much less efficient.

Excellent thermal insulation is guaranteed thanks to three sealing levels and the 6 chamber frame

Finally, the outer aluminum shell provides an additional barrier between the frame and outside air which further lowers thermal Uw-values, leading to an excellent thermal performance.

Security with Multipoint locking

Security plays a significant role when selecting suitable windows and doors for your home. The hardware components used must meet strict quality and security standards in order to provide adequate protection. Premium Winkhaus activPilot hardware is used to guarantee basic security, with a range of additional options and upgrades, including Resistance Class II (RC2) protection.

In locations where windows are particularly vulnerable to intrusion attempts, laminated security glass and impact resistant glazing are a good investment.

Customize and Individualize your Windows

In order to meet your personal requirements and tastes, the TwinSet  8000S models allow aluminum cladding can be customized in variety of different ways. You can select from an extensive range of RAL colors and finishes to match your facade, or accent it. Additional visual features such as muntins can be easily integrated making your imagination the only limit.
