Sound insulation towards the stairwell
Heavy door leaves with an increased sound reduction index, continuous sealing levels and a drop-down bottom seal: footsteps and voices from the stairwell stay outside — and your home becomes noticeably quieter.

The apartment entrance door separates your home from the stairwell — it should keep things quiet, close securely and still fit in with the building. We install certified door elements that combine sound insulation, burglary resistance and thermal protection, and replace old doors in occupied buildings with minimal disruption. Planning, preparation and installation stay in one pair of hands.

Apartment entrance doors with sound insulation and burglary resistance — planned, precisely prepared and replaced in existing buildings, in and around Regensburg.
Heavy door leaves with an increased sound reduction index, continuous sealing levels and a drop-down bottom seal: footsteps and voices from the stairwell stay outside — and your home becomes noticeably quieter.

Certified door elements of resistance class RC2 with multi-point locking, security strike plate and hinge-side protection. Security you don't see — but which is there when it matters.

A heated apartment and a cool stairwell create very different climates — simple door leaves warp under that strain. We use elements with the appropriate climate class, so the door still closes cleanly years later.

We usually replace an apartment entrance door within one working day: stairwell protected, cuts prepared, and by the evening your apartment is locked again. The appearance is matched to the building.

Wide-angle door viewer, high-quality lock cylinder, lever handle or knob, prepared for electronic access systems on request — we put together the fittings that suit your daily life.

Habe schon mehrmals Holz hier bestellt (Eiche massiv). Die Kommunikation war immer sehr freundlich und kompetent, das Holz war qualitativ hochwertig und die Lieferung prompt. Kann Wohnkultur7 daher nur empfehlen!

Ich komme schon seit vielen Jahren hierher, um qualitativ hochwertiges Holz zu erhalten. Gerade was die Auswahl und Exklusivität der Hölzer anbelangt, ist dieses Unternehmen im Umkreis von Regensburg die einzige richtige Anlaufstelle. … Vielen Dank für so viel Leidenschaft zu Holz und Qualität.
Wir haben 15 massive Eichen-Treppenstufen bestellt und sind mit der Qualität sehr zufrieden. Die Stufen wurden sauber gefertigt, waren maßhaltig und die Oberflächenqualität hat unsere Erwartungen übertroffen.
Sehr netter Kontakt. Auf alle meine Wünsche wurde eingegangen. Geliefert wurden drei wunderschöne Regale in Nussbaum. … Ich bin 100 % zufrieden. Tolle Handwerksarbeit.
Usually one working day. We prepare everything in the workshop, replace door and frame in one go and fully adjust the element the same day — by the evening your apartment is securely locked again.
RC2 is certified burglary resistance: the complete element — door leaf, frame, locking and hardware — withstands a break-in attempt with simple tools for several minutes. What matters is that everything fits together and is professionally installed.
That depends on the building: in a busy stairwell, a door leaf with a significantly increased sound reduction index plus continuous sealing and a drop-down bottom seal is worthwhile. We assess the situation on site and recommend the right specification.
The inside is yours — the appearance towards the stairwell often concerns the owners' association or the landlord. We choose elements that fit in with the building and provide the documents you need for approval.
Warm, dry air on the apartment side and a cool stairwell put stress on the door leaf — simple doors go out of true. Door elements with the appropriate climate class are built for exactly this difference and stay tight and smooth-running for good.
Honest advice, free of obligation, and a clear proposal for the next steps.
