UW- value ≤ 0.9

An uncompromising system for elite real estate, fully compliant with strict Passivhaus standards. The seven-chamber 88 mm thick profile structure provides record thermal insulation, turning the entrance door into an impenetrable barrier against summer heat. The static rigidity of the profile allows designing massive designer doors of increased height without risk of deformation under their own weight.

Three seal circuits create an isolated "dry chamber" for hardware, protecting mechanisms from corrosion, dust, and sea salt. Thanks to the ability to install extra-thick armored panels and glass, the 88 Puerta system guarantees maximum privacy and silence in the home. This is an investment in durability and comfort of the highest level.

FAQs

Frequently Asked Questions about Kömmerling 88 Puerta

Why is the 88 series considered the safest?

The massive profile allows installation of armored panels and glazing units up to 56 mm, as well as RC3 class hardware that is virtually impossible to break through with hand tools.

Can I order a very tall entrance door?

Yes, the statics of the 88 system allow manufacturing sashes up to 2.5 meters high without risk of distortion or loss of sealing.

How does the door perform in hurricane winds?

The system is certified to the highest air and water permeability classes. Even at wind pressure equivalent to a storm, not a single drop of water will get inside.

What infill options are available for the 88 series?

You can choose exclusive door panels with ceramics, natural stone, or concealed glazing that are installed flush with the frame profile.

Can the door be integrated into a Smart Home system?

Yes, there is enough space inside the profile for concealed routing of electric lock cables, status sensors (open/closed), and biometric scanners.

Does the door thickness affect ease of passage?

Despite its massiveness, hinges with needle bearings ensure easy opening. The force required to open is minimal.
