Glass and Mineral Wool Moisture Measurement Methods

Moisture in glass wool and mineral wool insulation is best measured using inline non-contact methods. Hammer-IMS uses M-Ray millimeter wave technology to detect moisture and basis weight variations contactlessly during production. The sensor transmits electromagnetic waves through the insulation material and analyzes the response to quantify moisture content, density, and thickness in real time—without slowing the line or requiring radioactive sources.

M-Ray technology uses millimeter wave electromagnetic signals—similar to those used in cellular communications—to penetrate and characterize materials. For glass wool and mineral wool, the sensor measures how the waves interact with the material to derive thickness, basis weight, and moisture-related properties. Because the waves pass through the full material depth, M-Ray captures volumetric data, not just surface readings.

Yes. M-Ray technology is entirely non-nuclear and non-radioactive, making it safe for continuous 24/7 operation alongside production personnel. Unlike X-ray or nuclear gauge systems, no radiation licensing, shielding enclosures, or restricted access zones are required. Workers can operate normally in the immediate vicinity of the measurement system without any health risk.

Yes. Hammer-IMS systems are validated for both glass wool and rock wool (mineral wool) production lines. The M-Ray sensor head is configurable to account for the specific density range and material characteristics of each type, providing accurate thickness and basis weight data regardless of the fiber composition or binder content of the insulation product.

The Hammer-IMS construction materials measurement system can simultaneously capture material thickness, basis weight, and anomaly deviations in a single inline pass. The multi-sensor head platform provides cross-machine direction coverage, enabling detection of local density or thickness deviations that may correspond to process irregularities such as uneven fiber distribution or binder application inconsistencies.

The Marveloc-CURTAIN platform based on the Marveloc 602 sensor supports measurement of materials up to 30 centimeters thick. This covers the full product range of standard glass wool and mineral wool insulation slabs, rolls, and boards encountered in typical building insulation and industrial insulation manufacturing processes.

Yes. Hammer-IMS offers both new turnkey installations and upgrades to existing production lines. The M-Ray OEM module can be embedded into machine builder platforms, and the system supports closed-loop production adjustment through real-time data output. Connectivity 3.0 software enables data logging, analytics integration, and remote monitoring via the Hammer-IMS IoT Industry 4.0 app.

Hammer-IMS actively serves customers in Belgium, Germany, France, the Netherlands, Australia, and Japan, with international reach beyond these core markets. The company has a North America team for customers in the US and Canada. Prospective customers can book a 30-minute introduction demo with the relevant regional team directly through the online calendar to discuss installation feasibility and requirements.
