Commercial Acoustic & Thermal Insulation

Designed for Modern Commercial Construction

Commercial buildings require insulation solutions that contribute to both acoustic and thermal performance. DecraBatt has been developed to provide effective sound absorption while also assisting with thermal efficiency in offices, education facilities, healthcare projects, retail developments and public buildings.

Manufactured from 100% polyester fibre containing a minimum of 75% recycled PET material, DecraBatt offers a lightweight alternative to traditional insulation products. Available in multiple densities and thicknesses, the product can be specified to suit a broad range of commercial applications.

Acoustic Insulation for Wall and Ceiling Systems

DecraBatt is commonly installed within partition walls and ceiling cavities where sound absorption is required. By reducing reverberation and controlling reflected noise, the insulation contributes to improved speech clarity and occupant comfort throughout commercial spaces.

The product is regularly used behind perforated wall panels, timber acoustic panels, PET acoustic panels and suspended ceiling systems where concealed acoustic absorption is required.

Commercial Ceiling Insulation for Improved Acoustic Performance

Suspended ceilings play an important role in controlling noise within commercial buildings. Installing Decrabatt acoustic insulation above ceiling tiles helps reduce sound transmission between occupied spaces while improving the acoustic performance of meeting rooms, offices, classrooms and healthcare facilities.

Decrabatt is lightweight, easy to cut and simple to install within standard ceiling grid systems. It provides both acoustic and thermal insulation without adding unnecessary weight to the ceiling structure, making it suitable for new construction and refurbishment projects.

Whether used in commercial offices, education facilities, retail developments or public buildings, Decrabatt contributes to quieter, more comfortable indoor environments while assisting builders and contractors to achieve efficient installation and long-term performance.

HVAC, Plant Room and Mechanical Services Applications

Mechanical equipment can generate significant noise throughout a building. DecraBatt provides an effective acoustic insulation solution for HVAC systems, plant rooms, acoustic louvres, duct silencers and mechanical equipment enclosures.

Its high sound absorption performance helps reduce reverberation within service spaces while supporting overall acoustic comfort throughout the building.

Acoustic Insulation for HVAC and Mechanical Services

HVAC systems are one of the primary sources of background noise within commercial buildings. Decrabatt acoustic insulation is designed for installation within air handling units, ventilation systems, ductwork and mechanical plant to reduce fan noise, airflow turbulence and equipment-generated sound before it reaches occupied spaces.

The lightweight insulation is easy to install within HVAC equipment and provides both excellent acoustic absorption and effective thermal performance. Its durable construction makes it suitable for commercial offices, hospitals, schools, shopping centres, airports, industrial facilities and other buildings where occupant comfort and building performance are important.

Whether specified for new construction or retrofit projects, Decrabatt helps create quieter, more energy-efficient HVAC systems while supporting long-term performance and ease of maintenance.

Why Choose Polyester Acoustic Insulation?

Unlike traditional fibrous insulation products, polyester insulation is easy to handle, low VOC, non-irritant and resistant to moisture absorption. DecraBatt can be cut and installed with standard construction tools, simplifying installation while maintaining consistent acoustic performance.

Available in both white and black options, DecraBatt can be concealed within wall cavities or used behind acoustic finishes where appearance and performance are both important considerations.
