Frequently Asked Questions

What is a sound deadening rubber sheet? A sound deadening rubber sheet is an engineered material, usually composed of butyl or synthetic rubber, designed to absorb and block sound waves and improve acoustic comfort in buildings, vehicles, and industrial equipment.

How do I choose the right sound deadening rubber sheet? Consider factors such as material composition, density, thickness, ease of installation, fire ratings, water resistance, and application scenario (vehicle, construction, machinery). Consulting with manufacturers like ASLONG can further tailor recommendations.

Can sound deadening rubber sheets be used outdoors? Yes, High Quality rubber sheets like ASLONG’s butyl mats are highly resistant to weather and UV, making them suitable for exterior panels and outdoor equipment enclosures.

What is the difference between mass loaded vinyl and rubber sound deadening sheets? Mass loaded vinyl relies on mass and limpness to block sound, while rubber sheets add damping properties to absorb vibrations. Each has distinct use cases; sometimes, hybrid or layered systems work best.

How does ASLONG support global clients? ASLONG exports worldwide and offers agent partnerships for local support. Their engineering and customer service teams assist in choosing, customizing, and shipping products suited for any project.
