Engineering EnvironmentsThat Perform
At Insulation Refractory and Acoustics (IRA), we deliver high-performance solutions for the most demanding environments. We specialize in the specialized—bringing together advanced thermal management, industrial refractory services, and precision acoustic engineering to create environments that are safer, quieter, and more efficient.
Our Expertise
Our work is built on three core pillars
Refractory Excellence
We provide specialized lining and maintenance for high-heat applications, ensuring industrial equipment remains durable, safe, and thermally efficient under extreme conditions.
Acoustic Innovation
Beyond simple soundproofing, we design comprehensive acoustic treatments. From managing noise transfer to optimizing internal sound quality, we create balanced environments for industrial sites, commercial spaces, and high-end residential projects.
Thermal Insulation
We help clients reduce energy costs and environmental impact through advanced insulation techniques that regulate temperature, protect infrastructure, and improve sustainability.
Our Mission
To deliver technical excellence through innovative materials and expert craftsmanship. We don't just install solutions—we engineer environments that perform.
Why Choose Us?
With a deep understanding of material science and structural requirements, we bridge the gap between industrial necessity and environmental comfort. Whether it's a high-temperature furnace or a world-class recording studio, we bring the same level of precision, dedication, and innovation to every project.
Our Story
Alwyn Hattingh, founder of Insulation Refractory Consultants (IRC) and Truesound Acoustics, identified a unique synergy between thermal insulation and acoustic engineering. The same mineral fibers—such as Rockwool and Ceramic Fiber—that withstand extreme heat also excel at absorbing sound.
Material Synergy
Leveraging refractory-grade materials with high thermal resistance and superior noise reduction properties, IRA delivers solutions that perform on multiple fronts—fire safety, thermal efficiency, and acoustic control.
Diversified Expertise
Insulation Refractory Consultants (IRC): Focused on industrial furnaces, boilers, and thermal insulation. Truesound Acoustics: Dedicated to precision acoustic engineering for studios, cinemas, and commercial spaces. Together, these entities share a supply chain, enabling cost-effective access to high-grade materials while maintaining uncompromising quality.
Industrial Noise Solutions
Standard acoustic foams fail under high heat, and conventional thermal blankets lack the density for effective sound dampening. IRA solves this challenge by combining refractory and acoustic engineering into turnkey enclosures that reduce noise, improve safety, and enhance efficiency.
Why This Integration Matters
The formation of the Insulation Refractory and Acoustic Group is more than a merger—it is a strategic alignment designed to serve clients with unmatched efficiency and expertise.
Holistic Engineering
We address the entire building envelope—protecting against heat (Aeroinsul), managing internal thermal energy (IRC), and mastering acoustics (Truesound).
Turnkey Efficiency
One point of accountability for industrial lagging, cladding, acoustic calibration, and residential insulation.
Unrivalled Expertise
Led by Alwyn Hattingh and a team of seasoned specialists, the Group combines over three decades of on-site experience and technical consulting.
Our Promise for the Future
Whether insulating a high-rise office, lining an industrial furnace, or designing a world-class broadcast studio, our mission remains clear: to engineer environments that perform without compromise.
At the Insulation Refractory and Acoustic Group, we don't just install materials—we engineer comfort, safety, and sound.
