Interior construction.

Raised and cavity floors create flexible installation spaces and enhance the adaptability of modern buildings. They integrate technical functions such as heating, cooling, ventilation as well as acoustic insulation directly into the floor system, thereby making a significant contribution to comfort, efficiency and future-proof interior construction.

Your benefits:

• High quality and reliable functional safety
• Simple and clean integration of building services and communications technology
• Quick access to the entire installation space
• Cost-effective solution for flexible interior design concepts
• Reduced need for separate support structures for cables, pipes and units
• High degree of planning and design freedom in the fit-out
• Usage-optimised floor systems for a wide range of requirements

Whether for offices, educational facilities, healthcare properties or commercial premises: rhtb: develops modern solutions for drywall construction and interior construction that convincingly combine functionality, design and cost-effectiveness.

Precise workmanship, short construction times and flexible system solutions create high-quality spaces offering superior user comfort, a balanced indoor climate and excellent thermal performance.

Our services:

• Floors: Raised floors made from various materials, dry and cavity floors with self-levelling screed, stepped constructions, flooring works as well as integrated heating and cooling systems.
• Walls: Plasterboard and fire-resistant walls, glass walls, flexible partition walls, special constructions and integrated heating and cooling systems.
• Ceilings: Plasterboard, metal, mineral fibre, perforated, acoustic and external ceilings, as well as high-performance heating and cooling ceiling systems.

With many years of experience in interior construction and the delivery of complex large-scale projects, rhtb: offers cost-effective, precise and on-time solutions as a general contractor. The use of modern planning and organisational tools such as BIM and Lean Construction ensures efficient processes, high-quality execution and reliability in project management.

From project planning through work preparation and execution to handover, rhtb: coordinates all services from a single source. The focus is on reliability, adherence to deadlines, transparent processes and close collaboration with clients – for smooth, quality-assured interior construction.

Your benefits:

• Efficient project management by experienced interface professionals using Lean Construction and BIM.

• Raised and cavity floors with customisable coverings.
• Comfortable and cost-effective heating and cooling ceiling systems.
• Technically sophisticated system partition walls.

With extensive experience in installing cooled ceilings across a wide range of system variants, rhtb offers high-performance solutions for a modern indoor climate. The company combines many years of expertise in interior construction with technical know-how in the field of energy-efficient heating and cooling systems.

Dry-construction heating and cooling ceilings ensure pleasant, draught-free radiant climate control in both summer and winter. Integrated into ceilings, walls and floors, they create economical and comfortable solutions for energy-efficient buildings – without disruptive air movements and with a high level of user comfort.

Your benefits:

• Threefold benefit: cooling, heating and a suspended ceiling in a single system
• Quiet radiant climate control for cooling and heating without draughts
• High comfort thanks to quiet operation without disruptive air movement
• Draught-free climate control without air turbulence or the spread of bacteria
• High cost-effectiveness due to low energy and maintenance costs
• Low installation height of around 15 cm – also ideal for retrofitting in existing buildings
• Improved room acoustics thanks to acoustically effective perforation designs

rhtb: offers modular partition walls for modern interior design concepts that combine high functionality, design quality and flexible use of space. The modular wall systems allow for a wide range of combinations for offices, educational buildings, healthcare facilities and other commercial sectors – tailored to the requirements of each individual project.

Room-in-room: Efficient system solutions for the growing demand for integrated quiet zones, meeting areas and workspaces.

Solid Walls: High-quality wall systems with reliable sound and fire protection properties for demanding interior design projects.

Acoustic Walls: Sound-insulating and sound-absorbing walls and doors for effective acoustic optimisation in interior construction.

Single Glazed Walls: Transparent glass partition walls for bright, open-plan concepts with high-quality design and functional spatial structure.

The range shown here is a selection of the diverse system partition solutions offered by rhtb. The range is complemented by an extensive door range that optimally combines function, design and system compatibility.

PORR is a technology leader in the planning and construction of sophisticated, customised customer requirements – safe and economical.

Our expertise – your benefit:

Holistic planning and execution

Smooth, punctual, accident-free and high-quality completion of your projects is essential for us. We offer all planning and construction services from a single source, from the execution of individual trades to cross-trade solutions including planning, site manager, delivery and installation of all materials.

Construction management: safe and economical

Cost-effectiveness and safety are at the centre of our solid construction management. Consistent, harmonised construction processes, transparency and the stringent implementation of measures for deadline and quality assurance are a matter of course for us.

Certified safety

We set the highest standards in terms of safety and quality. Our solutions guarantee reliable realisation and are confirmed by all the necessary test certificates .

Perfect project management

With sophisticated and proven digital control processes for the planning and execution phase, we ensure cost-effectiveness and safety in construction. Lean management methods help us to monitor and optimise construction progress on a daily basis so that all trades work together smoothly.

Optimised logistics and execution

Thanks to our own employees and the PORR network, we ensure optimal construction site logistics, punctual material deliveries as well as the organisation and execution of all necessary trades. Our promise: Construction from a single source.

Active deadline controlling and quality assurance

It is crucial for clients to be informed about the status of their project at all times. Regular budget and quality checks as well as an overview of schedule adjustments are essential. With our construction status report, you are always up to date.

Short runtimes

Thanks to our synchronised construction process and our many years of experience, we coordinate all work processes efficiently. Our experienced engineers simulate the construction process right at the start of a project, identify potential weak points and optimise the workflow.
