UW- value ≤ 0.9
PremiDoor 76 is the ideal balance between structure weight and thermal characteristics. The system operates on the "lift-and-slide" principle: when the handle is turned, the sash lifts above the guide rail, allowing even massive glass panels to be moved effortlessly. When closed, the sash lowers under its own weight, ensuring an airtight fit against the seals. This solution allows creating open, light-filled spaces while maintaining comfort and silence in the home even in windy coastal conditions.

FAQs

Frequently Asked Questions about Kömmerling PremiDoor 76

What maximum sizes can such a door reach?

PremiDoor 76 allows manufacturing structures up to 6 meters wide and up to 2.4 meters high. This is sufficient for most standard terrace exits in modern homes and apartments.

How well does this system protect against Spanish heat?

Thanks to the 5-chamber profile and the ability to install glazing units with selective coating, the system blocks thermal radiation, keeping the interior cool even under direct sunlight.

How secure are these doors against break-ins?

The weight of the sash and the complexity of the HST mechanism are themselves a deterrent. Additionally, RC2 class anti-burglary hardware and opening sensors for the security system can be installed.

Will there be drafts from under such a large door?

No, the HST system provides one of the highest airtightness ratings among all sliding structures because the sash settles tightly onto the seals under its own weight.

How does the aluminum threshold behave during rain?

The threshold is equipped with a system of drainage channels that effectively divert water outward, preventing it from entering the room even during heavy driving rain.

What colors is the PremiDoor 76 system available in?

The entire Kömmerling color spectrum is available to you: from classic white to anthracite and natural oak textures popular in Spain, with guaranteed UV resistance.
