Description

Getzner Sylodyn® bearing strips are specialized components made from durable, closed-cell PUR elastomer (polyurethane) that are crucial for high-quality acoustic construction. Their primary function is to eliminate the transmission of flanking sound (structure-borne noise) at component joints, significantly improving the overall acoustic performance of a building. By using the correct Sylodyn® strip, architects and contractors can achieve superior sound decoupling, often reducing or removing the need for additional, more complex sound control layers like dry lining.

Sylodyn® material is renowned for its low dynamic rigidity and exceptional durability, proving resistant to moisture, oils, and greases commonly found on construction sites. Its proven performance and outstanding ageing resistance make it the ideal, high quality material for long-term acoustic protection.

The Complete Sylodyn® Range

Gitco-sa.com supplies the complete range of Sylodyn® strips, identifiable by color coding and tailored to specific static and dynamic load requirements (up to 1.50 N/mm2  static load for the NF series):

• Sylodyn® NB (Red): Ideal for low-load applications.

• Sylodyn® NC (Yellow): Suitable for light to moderate structural decoupling.

• Sylodyn® ND (Green): Mid-range performance for balancing load and isolation.

• Sylodyn® NE (Blue): High static load capacity with excellent dynamic properties.

• Sylodyn® NF (Violet): Maximum load-bearing capacity for highly stressed joints.

The strips are available in standard thicknesses (e.g., 12.5 mm) with customized widths and optional self-adhesive backing upon request.

Key Applications of Getzner Sylodyn® bearing strips:

• Structural Decoupling: Isolating internal non-load-bearing walls, precast concrete elements, and masonry from the building structure to prevent flanking noise.

• Timber Construction: Critical for flank support and joint decoupling in modern timber-frame and CLT construction.

• Floating Structures: Used as resilient layers under linear supports, beams, or tracks to provide effective vibration isolation.

We guarantee that our Sylodyn® bearing strips are the best isolation products available, offered with superior high quality and a complete range to Dammam, Al-Khobar, Al Jubail, Riyadh, Jeddah, and across Saudi Arabia.

Know more about Getzner Sylodyn® bearing strips:

1. What are Sylodyn® bearing strips?Sylodyn® bearing strips are elastic components made from Getzner’s proprietary polyurethane elastomer. They are specifically designed for continuous or strip isolation between structural elements to prevent the transmission of sound and vibration.
2. What is the core material that provides the elastic properties?The core material is Sylodyn®, a high-tech, closed-cell polyurethane elastomer known for its excellent dynamic properties, low creep tendency, and high load-bearing capacity.
3. How is Sylodyn® different from Sylomer® in this application?Sylodyn® is typically preferred for structural isolation due to its higher resilience, which translates to a more precise, low-frequency tuning of the decoupled system, crucial for high-performance acoustic isolation.
4. What is the main function of the strips in construction?Their main function is to prevent sound bridges—rigid contact points between structural components—which are the primary pathways for flanking sound and structure-borne vibration to travel throughout a building.
5. Are the strips resistant to aging and moisture?Yes, Sylodyn® is a closed-cell elastomer, making it hydrolysis-stable (resistant to chemical breakdown by water) and impervious to moisture, ensuring its acoustic and mechanical properties are maintained for decades.
6. What type of sound transmission do the strips primarily address?They primarily address flanking sound and structure-borne sound/vibration, which are noise types that bypass the primary insulation layers through rigid connections.
7. How much acoustic improvement can be achieved with Sylodyn® strips?When used correctly in critical junctions (e.g., between walls and floors), Sylodyn® can achieve an improvement in the joint’s sound reduction index (∆R’w) often exceeding 10 dB.
8. Do the strips offer good damping properties?Yes, while highly resilient, the material still offers significant damping (vibration absorption), making it highly effective at dissipating vibrational energy rather than reflecting it.
9. What is the significance of the material’s “low creep tendency”?Low creep means the material’s thickness and performance remain stable over the entire service life, even under constant high loads, ensuring the acoustic performance of the building does not degrade over time.
10. What is the typical compressive stiffness range offered?The strips are available in a range of densities and thicknesses, with specific load ranges and dynamic stiffnesses tailored to the application, allowing engineers to precisely select the required compressive stiffness (Spring Constant, $\mathrm{C}$).
11. Where are Sylodyn® bearing strips most commonly applied?They are essential in the elastic decoupling of prefabricated concrete components and in modular timber construction, particularly in multi-story residential buildings.
12. Are they used for decoupling walls from floor slabs?Yes, they are often placed continuously underneath load-bearing walls (both timber and concrete) to isolate them from the foundation or floor slab below.
13. How are the strips used in timber construction?They are crucial in modern timber construction (like CLT or glulam) to decouple elements, especially at horizontal and vertical joints, ensuring the lower mass structure meets strict noise control requirements.
14. Can they be used for rail/tram track isolation near buildings?Yes, Sylodyn® materials, often in different formats, are extensively used in ballastless track systems to isolate rail vibrations from adjacent structures.
15. Are they suitable for highly sensitive areas like hospitals or recording studios?Yes, they provide the necessary precision and performance to meet the extremely high acoustic comfort standards required in sensitive facilities.
16. How are the strips typically installed?They are laid out seamlessly on the substrate along the intended line of the wall or beam. The next structural element is then simply placed directly on top of the strip.
17. Do the strips come in different colors?Yes, Sylodyn® strips are often manufactured in different colors to easily identify the specific density and load-bearing capacity on-site.
18. Are they supplied in continuous rolls or pre-cut pieces?They are typically supplied in rolls or long strips, which allows the material to be cut to the exact required length on the construction site.
19. What does the European Technical Assessment (ETA) signify?The ETA certification confirms that the bearing strips have been structurally and acoustically assessed according to European standards, ensuring they are reliable for static proof and technical planning.
