Renovation of a family home in the Sauerland region using SORIWA Multi Profiles

An old building with unique structural requirements

The renovation project described here involves a roughly 300-year-old apartment building in the Sauerland region. The building’s structural condition reflects its age: crooked walls, uneven corners and historic structural features make standard renovation solutions impractical. What is needed are customized, flexible systems that can be adapted to the irregularities and unique characteristics of an historic building.

System Selection: SORIWA Multi Profile

The project team therefore chose a drywall wall system using SORIWA Multi Profiles. This wall system is particularly well-suited for interior renovations in existing buildings, as its flexibility makes it ideal for walls with irregular contours. The profiles can be installed with a precise fit while also offering clear advantages during installation.

Project Description

The first floor of the building, which had last been renovated in 1950, underwent a complete gut renovation. This was followed by reconstruction work, tailored to the architectural features of the historic building. The work was carried out by Sternberg Bautechnik, a specialist contractor for high-quality interior construction.

Focus on Safe Installation

Mr. Sternberg, a master carpenter and managing director, shares his experience with conventional steel profiles: “My employees and I have cut ourselves on steel profiles so many times—some of the cuts even required stitches.”
After doing his own research on Instagram, Mr. Sternberg decided on the SORIWA Multi-System. A decisive factor was the safe and quick installation without sharp edges—a key feature of the SORIWA Multi profiles.

Frequently Asked Questions

Yes, the SORIWA Multi Profile is a product approved by the building authorities. It has a general building approval (abZ) and bears the Ü mark. This means it may generally be installed in Germany without restriction.

Certified documentation is available for the relevant application (e.g., wall constructions) regarding sound insulation, fire performance, emissions, and mechanical load-bearing capacity. The profile can therefore also be used in projects with special requirements.

  • One profile instead of three: replaces the entire conventional steel or wood framing
  • Safe to use: no sharp edges, minimized risk of injury, comfortable to the touch, lightweight
  • No changeover: familiar machining with standard tools, fine- and coarse-threaded screws, and the usual procedures
  • Climate-friendly: made from recycled cellulose with a negative carbon footprint (EPD)
  • Forward-thinking: recyclable and resource-efficient
