Silicone in the Construction Industry

Our Expertise – High-Quality Silicone Products for the Construction Industry

The modern construction industry faces ever-increasing challenges. Stricter environmental regulations, higher energy efficiency standards, and increased demands for the longevity of structures lead to an intensified use of innovative materials. Silicone has established itself as an indispensable material, convincing with its unique properties.

As a synthetic polymer with an exceptional material structure, silicone clearly stands out from conventional elastomers and plastics. Lindemann Silikon GmbH & Co. KG has decades of experience in the development and manufacturing of customized silicone solutions for the construction industry. Our products meet the highest quality standards and offer reliable solutions for demanding construction applications.

Key Application Areas of Silicone in Modern Construction

Facade Technology: Durable Sealing Solutions for the Building Envelope

The building envelope is exposed to extreme weather conditions. UV radiation, temperature fluctuations from -40°C to +80°C, and aggressive environmental influences place the highest demands on sealing materials. Our silicone profiles are specially developed for these demanding conditions and ensure a permanent seal for facade elements.

Our silicone solutions have proven particularly effective in the following facade applications:

• Structural glazing for curtain walls
• Connection joints between different building materials
• Expansion joints in large-area facade systems
• Sealing of window elements and door connections

Window and Door Technology: Precise Seals for Optimal Energy Efficiency

Modern buildings must meet the strictest energy efficiency standards. High-quality sealing systems play a crucial role in this. Our silicone molded parts are developed individually according to customer requirements and offer optimal sealing properties for window and door systems.

The particular advantages of our silicone molded parts are evident in:

• Excellent airtightness for minimal energy losses
• Permanent elasticity even with extreme temperature fluctuations
• Resistance to UV radiation and ozone exposure
• Long-term stable sealing effect without material fatigue

Sanitary and Heating Technology: Flexible Piping Systems

In modern building technology, increasingly complex piping systems are used. Our silicone hoses offer the necessary flexibility and temperature resistance for demanding installations. Thanks to their resistance to temperatures from -60°C to +230°C, they are ideal for heating and sanitary applications.

Fire Protection: Innovative Solutions for the Highest Safety Requirements

Fire protection plays a central role in modern building planning. Our specially developed inflatable silicone seals offer innovative solutions for fire protection applications. These systems activate automatically upon heat exposure and reliably seal openings in fire protection sections.

Product Portfolio for the Construction Industry

Silicone Hoses: Versatile Solutions for Technical Installations

Our silicone hoses for the construction industry are manufactured using high-precision extrusion processes. They offer exceptional quality for demanding applications in building technology. The construction industry particularly values silicone hoses for their durability and temperature resistance in heating, ventilation, and air conditioning systems.

Fabric-Reinforced Hoses: Highest Pressure Resistance

For applications with increased pressure requirements, our silicone fabric hoses offer the optimal solution. The textile reinforcement allows for use at higher operating pressures, while the silicone matrix ensures chemical resistance and temperature stability.

Molded Parts by Injection Molding: Precision for Complex Geometries

Complex silicone molded parts are manufactured using our modern injection molding process. This technology enables the production of precise components with complex geometries, which are required in the construction industry for seals, dampers, and insulation parts. Each molded part is developed and manufactured according to individual customer specifications.

Silicone Profiles: Custom Sealing Solutions

Our silicone profiles are specially developed for construction applications and offer optimal solutions for sealing applications, edge protection, and insulation. The profiles can be supplied in various hardnesses and colors to meet specific requirements.

Typical Applications in Construction Practice

Sealing Systems for Facades and Windows

Modern building envelopes require high-performance sealing systems that function reliably for decades. Our silicone products offer the necessary durability and weather resistance for:

• Structural glazing in office buildings
• Window seals in residential buildings
• Facade seals in industrial buildings
• Connection joints between different building materials

Fire Protection Systems and Safety Technology

Fire protection requires reliable materials that can save lives in an emergency. Silicone-based fire protection systems offer decisive advantages due to their temperature resistance and the absence of toxic fumes:

• Fire protection seals in fire doors
• Cable penetrations in fire walls
• Inflatable seals for automatic fire compartments
• Smoke protection seals in escape routes

Technical Building Equipment

Modern building technology places high demands on sealing and connecting elements. Silicone products prove particularly effective in:

• Heating and cooling systems
• Ventilation and air conditioning systems
• Sanitary installations
• Electrical installations with moisture protection

Special Applications in Building Construction

Innovative building concepts often require customized solutions. Our development department works closely with architects and planners to develop individual silicone solutions:

• Movement joints in large buildings
• Vibration dampers for building technology
• Weather protection seals for special applications
• Insulation elements for energy-efficient buildings

Quality and Certifications

Compliance with Important Building Standards

Our silicone products comply with all relevant norms and standards of the construction industry. Regular tests and certifications ensure the consistently high quality of our products. Particularly important are the fire protection standards, which play a central role in modern building planning.

Sustainable Material Development

Sustainability is becoming increasingly important in the construction industry. Silicone contributes to sustainable building concepts through its durability and recyclability. The long service life of our products reduces maintenance effort and material consumption over the entire useful life of a building.
