Exterior Walls:

Configurations for new builds and prefabricated house reconstructions using GUTEX Thermofibre®, Thermoflex®, and Multitherm® products, with U-factors and phase shifts for different insulation thicknesses.

Lightweight Partition Walls:

Timber and metal upright constructions with options for single and double panelling, with noise insulation values (RW) from 37 to 62 dB.

Concrete Ceilings:

Recommendations for cement screed and mastic asphalt applications, focusing on impact noise attenuation and thermal insulation, with specified U-factors and standard impact noise levels.

Beamed Ceilings:

Structures for new builds and reconstructions, emphasizing noise insulation and impact noise attenuation, with standard impact noise levels and assessed noise insulation values.

Key Parameters:

U-factor: Indicates thermal insulation efficiency.
Phase shift: Reflects the time delay in heat transfer through the structure.
Noise insulation value (RW): Measures the ability to reduce sound transmission.

Conclusion: The document serves as a comprehensive guide for constructing energy-efficient and acoustically optimized building elements using GUTEX products, with detailed specifications and performance metrics for various applications.

JThe requirements and recommendations are defined in DIN 4109. Components are supposed to dampen and/ or minimise the noise outside and inside the building. For noise protection, a distinction is drawn between airborne noise and impact noise.

Fire protection Environmental compatibility GUTEX understands fire safety as protection for people and animals against fire. Fire safety, however, also means minimising the resultant damage. The requirements for building fire safety are regulated by the countries concerned. There are two distinctly different requirements. One is the building material class or its fire behaviour and the other is the fire resistance class of a component. Building material classes or fire behaviour fall into classes A = "nonflammable" to F = "highly-flammable". For the construction industry, however, the minimum...
