Vibration Isolation spring for building service equipment and inertia block


Vibration Control

Zemac's advanced vibration isolation systems, features a proven system of engineered springs, dampers, and inertia blocks to effectively mitigate disruption from machinery and equipment vibrations. By isolating noise and vibration at the source, we help maintain optimal performance and comfort for every application. 


Acoustic Finishing

Zemac's architectural acoustic finishing solutions seamlessly integrate superior sound absorption and aesthetic appeal for any project. From lecture halls to offices, our tailored acoustic treatments enhance the listening experience while complementing the desired design, ensuring optimal acoustic performance.


Noise Control

Our noise control expertise ensures building services like ventilation, exhaust, and fans function efficiently without compromising occupant comfort. Our silencers and acoustic enclosures mitigate disruptive noise, creating a peaceful indoor environment while preserving essential airflow and building performance.



Zemac provides end-to-end consultancy for green building acoustics, environment, and sustainability. From early architectural planning to final construction, our services encompass design, specifications, on-site inspections, and testing to ensure seamless implementation of sustainable solutions. We work with you every step of the way. 



We offer comprehensive acoustic testing and commissioning for new construction and building renovations. Our experts can help you establish performance criteria and verify compliance. We can provide comprehensive reports and assessments to help you achieve  critical sustainability standards and building regulations including BEAM Plus 


Clean Rooms

We bring expertise to ensure that the complex services within clean-rooms, including water, waste, gas, and ventilation work in harmony. We engineer solutions to control the unique noise and vibration characteristics of these systems, creating the optimal environment for specialty production, processing, and storage.


R&D Facilities

R&D labs that utilize acoustic, vibration, and climate control require specialized engineering. We offer tailored solutions that ensure these sensitive environments meet stringent performance and regulatory requirements for your project.



Medical facilities require a variety of functional spaces including, Transmission Electron Microscope Imaging, PET-MRI Labs, and EMI & Radiation Shielding. We offer engineering, design, and installation for room enclosures to support these specialized areas.


Data Centers

Acoustics are critical in data centers as cloud and AI technologies drive growing demand. Managing  acoustic performance is essential to mitigate noise from servers and equipment. The solutions we deliver also help you achieve your energy saving and sustainability targets.
