The GreenGirt CMH™ continuous insulation system is flexible to meet and exceed project requirements and preferences, especially for various insulation types. One common insulation choice utilized with GreenGirt CMH is mineral wool. This combination includes several benefits that promote high-quality performance within a building’s walls. This article discusses the benefits of using mineral wool insulation with GreenGirt CMH, and 3 instances that demonstrate the effectiveness of this combination.
The Benefits of Using Mineral Wool with GreenGirt CMH

Excellent Thermal Performance
Mineral wool’s naturally high R-value helps establishes consistent interior temperatures and improves overall energy efficiency. When paired with GreenGirt CMH, mineral wool’s R-value is retained as the system eliminates thermal bridging and creates a stable platform for continuous insulation. GreenGirt CMH includes ThermaLock technology that holds the insulation in place, thus eliminating the need for stick pins and other fastener retention tools and eliminates thermal bridging entirely.
Superior Fire Resistance
Mineral wool is noncombustible and has a high melting point, which enhances the building’s fire safety. GreenGirt CMH’s composite design avoids creating pathways that can compromise fire resistance.
Moisture Management
Mineral wool is vapor-permeable and quick-drying, helping to resist moisture penetration. GreenGirt CMH supports the insulation with an open design that allows for effective drainage and ventilation, keeping the insulation moisture-free.
Enhanced Durability and Dimensional Stability
The insulation holds its shape and does not settle over time, ensuring long-term thermal performance. GreenGirt CMH’s rigid, corrosion-resistant framing provides stable support for mineral wool, preventing compression and maintaining the integrity of the insulation layer.
Improved Acoustic Performance
Mineral wool’s dense structure offers excellent sound absorption, reducing noise transmission. Combined with the strong, continuous backing of GreenGirt CMH, this can contribute to quieter interior environments.
Environmental Sustainability
This insulation often contains recycled content and is fully recyclable at end-of-life. GreenGirt CMH’s durable composite design extends the building envelope’s lifespan and decreases the need for replacement materials, reducing embodied carbon emissions and promoting sustainable building.
Malcolm X College

Construction of Malcolm X College in Chicago, Illinois, which used the GreenGirt CMH continuous insulation system on the building’s walls with mineral wool insulation.
The Malcolm X College project in Chicago, Illinois is an educational facility designed to house health sciences, general education, and adult education. This building also supports student services and athletic needs. Included in this building is a conference facility, auditorium, and parking garage. To capitalize on energy efficiency and durability, this project installed GreenGirt CMH vertically at 5” deep and 24” on center, with mineral wool insulation and metal panel cladding, showcasing the effectiveness of using mineral wool and GreenGirt CMH together.
San Francisco International Airport Terminal 1C

Construction of San Francisco International Airport Terminal 1C in San Francisco, California, which used the GreenGirt CMH continuous insulation system on the building’s walls with mineral wool insulation.
The San Francisco International Airport Terminal 1C project in California is the renovated airport terminal that was engineered to meet the needs of modern travel needs and to revolutionize the travel experience for patrons. The upgrade included improved passenger amenities, renovated arrival and departure areas, mezzanine connections to the Air Train, and a 25-gate terminal to accommodate larger jets. Designed with sustainability and structural integrity in mind, the project installed GreenGirt CMH horizontally and vertically on the building’s walls at 2” deep and 16” on center, with mineral wool insulation and ACM cladding.
The Hub Mixed Use Building

Construction of the Hub Mixed Use Building in College Park, Maryland, which used the GreenGirt CMH continuous insulation system on the building’s walls with mineral wool insulation.
The Hub Mixed Use Building in College Park, Maryland is a 9-story student housing building for the University of Maryland. This building includes high-quality amenities such as a rooftop pool, high-end interiors, café spaces, 161 residential units, a state-of-the-art gym, and a parking deck. To ensure this building was protected from moisture penetration and fire-resistant, GreenGirt CMH was installed horizontally on the building’s walls at 4” deep and 16” on center, with mineral wool insulation and a combination of fiber cement and ACM cladding, emphasizing the benefits of using GreenGirt CMH and mineral wool insulation together.
Conclusion
Using mineral wool insulation and GreenGirt CMH together is an unstoppable duo that capitalizes on the thermal efficiency and durability of buildings that utilize this combination. The Malcolm X College, SFO T1C, and Hub Mixed Use buildings demonstrate the effectiveness in using this combination through high-quality thermal efficiency that does not sacrifice durability or environmental sustainability.
