– Front doors
Convincing features >>>
Certified for cold climate zones
by the Passive House Institute Darmstadt: highest Passive House Efficiency Class A
Flush threshold:
The perfectly thermally separated threshold profile from the inside to the outside is critical for optimal thermal insulation
Thermo rigid foam profile:
Thermal foam profile between the wood inside and the aluminum cover shell outside for best insulation values
Wood inside:
slim and elegant frame made of local softwood in spruce (optional in larch or oak)
With the invisibly installed A-opener, the door can be opened comfortably by motor on impulse and, e.g., with a finger printer. Power supply via a tappet contact
Enhanced burglary protection:
The lock locks automatically in the main latch and in two additional locks – even when unlocked
A maximum of safety:
Three to four asymmetrically arranged solid special belts also ensure the best possible safety
Integrated handle bar – functionality meets design
The straight-line appearance harmonizes ideally with the clear lines of the ENERsign® elements and modern architecture
Modern technology, individual design
The certified ENERsign®primus entrance door offers a maximum amount of glass and ensures that the entrance area is flooded with light. Light is life.
The opaque entrance door also meets all requirements, such as driving rain resistance, stability, and burglary protection. The plinth profile is pleasantly low. The threshold height is naturally flush.
Optimal thermal insulation
The sophisticated design of the ENERsign®primus entrance door guarantees a high surface temperature due to the perfectly thermally separated lower leaf profile on the inside. This prevents unfavorable heat loss on the outside – so it stays pleasantly warm in the entrance area.
Security and comfort
Increased burglary protection with the ENERlock system:
The lock automatically locks the front door in the main latch and in two additional locks – one in the upper and one in the lower part of the door. The door is thus locked at three points – a maximum of security, even when unlocked.
Three to four pieces of asymmetrically arranged solid special hinges also provide the best possible security.
With the concealed built-in A-opener, the entrance door can be opened conveniently by motor on impulse, is suitable, e.g., for pushbuttons, as well as for code entry, finger printer, or radio transmitter.
