Are sound-absorbing mats always fitted to sheet metal?
No, they can also be fitted to plastic, composite and other hard materials where vibrations occur.
Are your bitumen products fire rated?
Yes, several of our products have fire ratings, such as UL94 V-2 or FMVSS 302, depending on the material type.
Are your heavy layers available in mouldable versions?
Yes, we also offer softer variants of heavy layers when the design requires a high degree of formability, particularly in confined installation spaces.
Are your sound-deadening mats suitable for vehicles?
Yes, both bitumen and heavy-duty sound-deadening material are used in vehicles to reduce structure-borne noise in doors, floors, roofs, engine compartments and load compartments.
Can the tongue-in-cheek approach be used in temperature-sensitive environments?
Yes, some types of heavy-grade asphalt can withstand temperatures of up to +130°C (+160°C) and are suitable for use where bitumen is not sufficient.
Can you help me choose the right damping material?
Absolutely. We analyse the design, frequencies, installation environment and weight requirements, and recommend the most cost-effective and functional material.
Do you stock self-adhesive sound-absorbing mats?
Yes, several of our bitumen and heavy-duty membrane products are available with a self-adhesive backing for quick and easy installation directly onto sheet metal or plastic.
How do sound-absorbing mats affect the noise level in products?
Adding mass reduces vibrations, which leads to lower noise levels and less resonance in everything from machinery to vehicles and white goods.
How do you choose the right weight class for bitumen or heavy-grade asphalt?
A higher density provides better vibration damping. We recommend materials based on thickness, frequency levels, design requirements and the installation environment.
How does bitumen work as a shock-absorbing material?
Bitumen has a high density and effectively dampens vibrations. When the material is installed on a surface, structure-borne noise and resonance are reduced, resulting in a more stable and quieter structure.
How quickly can you deliver sound-absorbing mats?
We hold large stocks across several weight grades and can deliver quickly, both standard sheets and custom-cut parts.
Is it possible to get bespoke shapes and dimensions?
Yes, we die-cut and cut all sound-absorbing mats to custom shapes – from small details to large panels.
What is soundpadding abd what is it used for?
Soundpadding is a vibration- and structure-borne noise-damping material that is fitted to sheet metal or plastic. We use it in everything from heat pumps and white goods to vehicles and ventilation units.
What is the advantage of LD13AL with aluminum surface?
It has a durable and wipeable aluminum surface and is fire resistant. Perfect where the surface may be exposed to heat or requires high durability.
What is the difference between soundpadding and heavy-layer?
Soundpadding is a bitumen-based material that is often supplied with self-adhesive backing. Heavy-layer is a heavier damping material that is available in several weight classes and also in softer, more malleable varieties.
What is the LD Soundpadding range suitable for?
LD4, LD13 and LD17 are self-adhesive, bitumen-based damping pads used for vibration damping in thin sheet metal, heat pumps, white goods, ventilation systems and vehicles. Each variant has a different thickness and weight.
What temperatures can bitumen-based dampers withstand?
Our bitumen solutions typically withstand –20°C to +80°C depending on quality. Heavy layers can withstand even greater temperature ranges, some up to +130°C (+160°C).
When are damping mats with two self-adhesive surfaces (LDL) used?
LDL with double-sided adhesive surfaces is used when the material is to be fitted between two surfaces and act as a vibration-damping intermediate layer.
When should you use a heavy-grade mix instead of bitumen?
Heavy-duty sheet metal is used when greater weight capacity, better flexibility or higher temperature resistance are required. It is commonly used in vehicles, industrial enclosures and large machinery.
Which industries use soundpadding and heavy layers?
Our materials are used by the automotive industry, the construction and ventilation industry, white goods manufacturers, the energy sector and producers of machinery and technical enclosures.
