Description

Getzner Sylodyn washers are essential components for achieving comprehensive acoustic isolation in construction. As sound control is only as good as its weakest link, these elastically decoupled washers are vital in preventing sound bridges at crucial fastening points like screw connections and bolted joints.

Made from the highly resilient Sylodyn® PUR elastomer, these washers deliver effective vibration isolation and decoupling. They are characterized by long-term stable material properties, ensuring they will not embrittle over time as they are completely free from plasticizers. This high quality ensures reliable, durable acoustic performance throughout the structure’s lifespan. Their installation is key to ensuring that forces are transferred structurally while dynamic energy (vibration/noise) is interrupted.

Key Applications of Sylodyn washers

• Timber Construction: Critical for use in conjunction with angle brackets, metal plates, and structural connections to maintain the acoustic integrity of decoupled walls and floors.

• Façade and Cladding Attachment: Decoupling exterior metal components attached to the main structure to prevent noise and vibration from external sources (e.g., wind, traffic) from entering the building.

• Machine/Equipment Mounting: Used under bolt heads and nuts when mounting equipment (HVAC, light machinery) to isolate their operating vibration from the building structure.

We proudly offer these high-quality Sylodyn® washers as the best isolation products in the market. Gitco-sa.com ensures the complete range is available for delivery and support in Dammam, Al-Khobar, Al Jubail, Riyadh, Jeddah, and across Saudi Arabia.

Know more about Sylodyn washers:

1. What are Getzner Sylodyn® washers?They are elastic washers made from the high-tech polyurethane elastomer Sylodyn®, designed to be inserted into screw or bolt connections.
2. What is the main purpose of using these washers?Their main purpose is to elastically decouple metal fasteners (screws, bolts, rods) from the surrounding structure to prevent them from becoming structure-borne noise bridges.
3. What key acoustic issue do the washers solve?They prevent the direct, rigid contact between the screw head/nut and the structural component, thus stopping vibrations and flanking sound from transmitting through the fastener.
4. What material are the washers made of?They are made from Sylodyn®, a closed-cell elastomer with pronounced spring and damping characteristics, ideal for long-term vibration isolation.
5. Are these washers used alongside other Getzner products?Yes, they are typically used as part of a coordinated system that includes Sylodyn® bearing strips or pads, ensuring the entire structural joint is decoupled.
6. Are the Sylodyn® washers available for standard screw sizes?Yes, the dimensions are adapted to common screw and bolt sizes, typically including M8, M10, M12, and M16.
7. Do the washers come in different thicknesses?Yes, they are available in different bearing thicknesses (e.g., 6 mm, 8 mm, 12 mm) to achieve varying efficiencies of insulation based on the application.
8. What is the purpose of the variant with a centring aid?The variants with a centring aid (groove) are designed to facilitate easier installation and ensure the exact positioning of the screw within the hole, guaranteeing proper isolation.
9. What is the recommended maximum torque strength for installation?The maximum permissible torque strength for tightening the screw needs to be respected to avoid compressing the elastomer too much, which would compromise its elastic properties (specific values are available on Getzner data sheets, e.g., 1 Nm for M8-6).
10. What is the material’s flammability rating?The Sylodyn® material in the washers meets fire behavior standards in accordance with DIN EN 13501-1 (Class E).
11. Where are Sylodyn® washers most critical in building construction?They are most critical in timber construction (especially modular and element construction) where the lower mass of the structure makes the transmission of flanking sound through fasteners a major acoustic challenge.
12. Are they used for suspending false ceilings or only for main structural connections?They can be used for both, but their primary application is the structural decoupling of components like shear walls, floor diaphragms, and beam connections.
13. Can the washers be used for isolating mechanical equipment?Yes, they are highly effective for elastically decoupling machine or equipment feet that are bolted to a structure, helping to reduce the transmission of equipment-generated vibrations.
14. Do they provide any electrical isolation benefits?Yes, the washers are electrically non-conductive, which can be an advantage in certain installations where contact between metal parts needs to be avoided.
15. Are they resistant to oils and greases?The polyurethane material is formulated to be resistant to common oils and greases, making them suitable for use in various industrial and construction environments.
16. How long do the material properties remain stable?The material properties are designed to remain constant over the long term (decades), as the elastomer is free from plasticizers that can cause embrittlement or material fatigue.
17. Is the installation simple?The installation is simple but requires the correct sequence: the hole for the screw should be pre-drilled in the component above the bearing, and the screw head/washer should be countersunk to ensure the washer is positioned correctly and not overloaded.
18. Are the washers designed for high-load applications?They are designed to handle the required loads for a screw connection while ensuring dynamic effectiveness. Their load capacity must align with the specified static load limit of the Sylodyn® material used.
19. Do they offer any thermal benefits?The elastomer material also offers properties of being thermally insulating, which provides a secondary benefit in terms of energy efficiency in the joint.
