What We Learned Specifying MLV for a Dubai Industrial Project

Mass loaded vinyl is one of those materials that sounds straightforward until you are actually specifying it for an industrial environment. The weight, the STC rating, the substrate compatibility, the temperature tolerance in a UAE climate — each of those variables matters, and getting even one of them wrong means the installation underperforms in ways that are expensive to fix after the fact.
We were brought in as acoustic consultants on a mid-scale industrial facility in Dubai Industrial City — a manufacturing unit with heavy machinery generating significant low-frequency noise that was causing compliance issues with the adjacent office block on the same plot. The brief was straightforward: reduce airborne noise transmission through the shared partition wall and the mechanical room ceiling to within acceptable limits.
We had used MLV on residential and commercial projects before, but this was the first time we were specifying it in a continuous heavy-industrial context. On the recommendation of another consultant we had worked with previously, we reached out to desound early in the specification stage rather than after the design was already locked. That decision made a material difference to how the project came together.
Why industrial MLV specification is not the same as commercial
The first thing the desound team clarified for us was a distinction we had underweighted in our initial specification: MLV performance in a residential or commercial setting and MLV performance in a continuous industrial environment are not the same conversation.
In a commercial office fit-out, MLV typically handles intermittent airborne noise at mid to high frequencies. The material is installed once, the acoustic load is predictable, and the ambient temperature is controlled. Industrial is different on every one of those variables:
- The noise load is continuous, not intermittent. Heavy machinery running eight to twelve hours a day generates sustained vibration and low-frequency pressure that residential-grade MLV is not formulated to handle over time without degradation.
- Temperature ranges in UAE industrial facilities are extreme. Mechanical rooms adjacent to production floors can exceed 50°C in summer. MLV that has not been specified for high-temperature tolerance will soften, lose mass uniformity, and drop in STC performance over the first full summer.
- Low-frequency transmission requires higher surface mass density. The machinery in this facility had dominant frequencies below 200Hz. Hitting those frequencies effectively requires a significantly heavier MLV specification than standard commercial applications.
- Substrate compatibility cannot be assumed. Concrete, steel decking, and block walls all behave differently under MLV installation. The wrong adhesive or mechanical fixing method creates flanking paths that bypass the mass barrier entirely.
Our initial specification had addressed some of these and missed others. The pre-installation review caught the gaps before they became post-installation problems.
How the specification was revised
The revised specification came out of a technical review that covered the facility drawings, the machinery noise profile data we had collected on site, and the substrate conditions in each treatment zone. The outcome was a layered approach rather than a single MLV product applied uniformly:
- The shared partition wall received a high-density MLV layer specified for the dominant low-frequency content, installed with a decoupled batten system to prevent direct contact with the block substrate and eliminate the flanking risk.
- The mechanical room ceiling used a composite assembly — MLV combined with a resilient layer — to address both airborne transmission and structure-borne vibration from the HVAC equipment mounted above.
- Penetrations and service entries were treated individually. Every unsealed penetration is a flanking path, and in an industrial facility the number of service penetrations through a partition wall is significant. Each one was detailed and sealed as part of the specification.
- High-temperature tolerance was written into the product specification as a minimum requirement, not an optional attribute. This ruled out several lower-grade MLV products that would have been technically compliant on STC rating alone.
What the installation delivered
Post-installation measurement was conducted six weeks after completion, after the facility had returned to full production. The results came in within the target range across all treatment zones. The office block noise level dropped to within compliance thresholds, the client passed the regulatory review, and the facility resumed normal operating hours without restriction.
What specifically held up:
- Industrial-grade MLV specification performed as modeled. The high-density product specified for the partition wall hit the target STC contribution. No post-installation remediation was required on the primary treatment surface.
- The decoupled installation eliminated the flanking risk. Measurements confirmed that low-frequency energy was not bypassing the treatment through the substrate. The batten system added installation time but removed the single most common failure mode in MLV applications.
- Penetration sealing contributed meaningfully to the result. Acoustic treatment is only as good as its weakest point. In this facility, the service penetrations were the weak points. Treating them as part of the primary scope rather than a secondary concern made a measurable difference to the final reading.
- Temperature performance held through the first UAE summer. A follow-up check at twelve months confirmed no degradation in the MLV layer. The high-temperature specification requirement was not over-engineering — it was the correct call for this climate.
If you are specifying acoustic treatment for an industrial facility in the UAE, the specification questions for MLV are genuinely different from commercial applications, and getting them right before installation is significantly less expensive than correcting them after. Their Mass Loaded Vinyl in Dubai product range includes industrial-grade options with the surface mass density and temperature tolerance that UAE industrial environments actually require.
Three things we would do differently from the start
Engage the supplier at specification stage, not procurement stage. The revision we made to the original specification saved us from a post-installation problem. That conversation could have happened two months earlier if we had not treated MLV as a commodity purchase.
Write temperature tolerance into the spec as a minimum requirement from the beginning. In the UAE, this is not an edge case — it is a baseline condition that should appear in every industrial acoustic specification regardless of the facility type.
Treat penetrations as primary scope from day one. On this project we initially scoped them as a secondary item. The measurement data after installation confirmed they were not secondary at all. Every unsealed penetration is a direct path for the noise you are trying to block.
