#OTHER CONSTRUCTION MATERIALS
Hayadamper DA-8D-A is a constrained vibration damping material made by laminating aluminum foil with a base-polymer made of butyl rubber, which has excellent chemical-stability, vibration-absorbing properties, and environmental isolation properties.
Key Features:
High damping performance:
Effectively reduces noise caused by vibration and impact, maintaining performance across various temperatures.
Strong adhesion in low temperatures:
Ensures stable adhesion even in harsh conditions, such as winter construction sites.
Flexible and easy to process:
Conforms to curved surfaces and is simple to cut and handle.
Health & environmentally friendly:
Free from formaldehyde, volatile organic compounds (VOCs), endocrine disruptors, halides, and heavy metals, making it safe for both human health and the environment.
Application:
■ Metal roofs – Reduces rain noise
■ Rain noise on metal roofs
■ Footstep noise on metal stairways
■ Operational noise from shutter boxes
■ Motor noise and vibrations from household equipment and appliances
■ Automobile noise
