FAQs

Frequently Asked Questions about Kömmerling PremiDoor 88

What does passive house certification mean for a system?

This is the highest global standard for energy efficiency. The 88 series windows minimize heat exchange so much that the house can maintain a comfortable temperature without active use of air conditioning.

What is the maximum opening width that can be covered with one structure?

The system allows creating structures up to 6.5 meters wide. This makes it possible to replace an entire living room wall with a transparent panoramic exit to the pool.

How easy is it to break such a door during a break-in attempt?

The 88 series system is extremely massive and strong. Combined with laminated glass and special hardware, it meets the strictest European security requirements, making penetration virtually impossible.

Can this system be installed with an absolutely flat threshold?

Yes, the PremiDoor 88 system is designed for integration with Lux thresholds that are fully recessed into the floor level, leaving no protrusions for unobstructed passage.

Do these doors support electric drive installation?

Absolutely. For structures of this scale, hidden automation is often ordered, allowing giant sashes to be opened with the push of a button on a smartphone or remote control.

Will condensation form on the glass during temperature changes?

No, the use of a "warm" spacer in glazing units and the multi-chamber profile structure prevent condensation, keeping the glass perfectly transparent in any weather.
