Decidamp CLA

lightweight constrained layer vibration damping tile

Decidamp® CLA combines an aluminum face with a reinforced viscoelastic core, expertly designed by Pyrotek engineers to minimize vibration in heavy-gauge structures. These semi-rigid tiles feature a unique blend of mechanical strength and viscoelasticity, effectively absorbing significant mechanical energy from vibrating substrates.

Ideal for aluminum metal structures and rigid plastics like ABS and FRP, which are prone to transmitting noise under vibration, Decidamp CLA offers a powerful damping solution. When applied to at least 70% of a structure, it significantly reduces vibration, decreases radiated noise, and improves transmission loss, making it particularly effective for addressing low-frequency noise challenges.

Lightweight and easy to install, Decidamp CLA features a peel-and-stick backing for faster application compared to traditional insulation methods. Its flexible viscoelastic layer ensures strong adhesion and optimal contact with installation surfaces. Additionally, its high damping efficiency allows for thinner constraining plates, enabling lighter metal components while maintaining structural integrity. Thinner plates also enhance flexibility, simplifying installation on curved surfaces and reducing overall system weight.

Installation

Decidamp CLA combines innovative design and ease of application to deliver superior noise and vibration reduction with time and cost savings. Its peel-and-stick adhesive backing eliminates the need for messy sprays or complex procedures, ensuring a clean and efficient installation process. By requiring up to 10% less material than comparable products, Decidamp CLA saves labor and material costs while maintaining exceptional performance.

The following is a brief summary of key installation notes and should not replace the detailed instructions provided in the Decidamp CLA Installation Guide. For comprehensive guidance and safety information, always refer to the full guide or consult your local Pyrotek representative.

Proper installation begins with preparing the surface to ensure it is clean, dry, and free of contaminants. The adhesive liner must be removed completely, and the material allowed to relax briefly before application. Decidamp CLA is applied with firm pressure to achieve a secure bond, ensuring coverage of at least 70% of the target surface for optimal performance. For added convenience, the product is easy to cut to size and can be installed using basic tools such as a utility knife and roller, making it ideal for various structural applications.
