Why Butler Building Contractors Specify the CMR-24 Roof System
360 degree Pittsburgh double lock seam
The MR-24 and CMR-24 panels are a singular steel covering providing unparalleled protection across entire buildings. Both seams feature a 2.75 inch seam height, a unique trapezoidal lower section and a lap seam on top. This feature coupled with the 360 degree Pittsburgh double lock seam with an additional 180 degree field rolled guarantees superior performance and protection against the elements. This is the tightest most durable panel seam available in commercial metal roofing today and it is the primary reason the CMR-24 carries the highest UL Class 90 wind uplift rating in the industry.
Superior quality rigid insulation board
Superior quality rigid insulation board is available in a variety of thicknesses and insulating values. The CMR-24 supports rigid board insulation with R values up to R-40 making it an excellent choice for buildings requiring enhanced thermal efficiency such as climate controlled warehouses, manufacturing facilities and office buildings. No other standing seam roof system in the Butler lineup delivers this level of thermal performance making the CMR-24 the clear choice for any Butler building project where energy efficiency and code compliance are the top priority.
Interior steel liner for a finished ceiling appearance
The interior metal liner protects the insulation and gives the building interior a finished look with excellent energy performance. An interior steel liner panel is available in 28, 26, 24 or 22 gauge Mod-36 liner which provides a finished ceiling and contributes to diaphragm strength. For Butler buildings where a clean professional interior ceiling appearance is required the CMR-24 liner eliminates the need for a separate ceiling system saving time and money while delivering a polished result that reflects the quality of the entire Butler building system.
Specially designed bearing plate for structural integrity
A specially designed bearing plate evenly distributes the weight of the roof panels and clips to support the structural steel. The integrated bearing plates distribute loads evenly over the framing. This critical engineering detail ensures that the added weight of the rigid insulation board and liner panel is properly transferred to the structural framing of your Butler building without creating point loads or stress concentrations that could compromise the long term structural integrity of your roof system.
Floating clip system for unrestricted thermal movement
High strength stainless steel clips allow panels to expand and contract freely. The CMR-24 inherits the same floating clip system that has made the MR-24 the industry standard for thermal movement management in standing seam roof systems for over 50 years. Regardless of temperature swings the floating clip system allows the entire roof assembly including the rigid insulation and liner panel to move freely without stressing the seam or creating gaps in the weathertight envelope of your Butler building roof.
Continuous vapor retarder for moisture control
The continuous vapor retarder means that the membrane between the liner and insulation has controlled moisture protection. For Butler buildings in humid climates or climate controlled environments where condensation management is critical the CMR-24 continuous vapor retarder provides a complete moisture control solution that is fully integrated into the roof assembly from the factory. No field applied vapor barriers. No gaps in coverage. Just a complete engineered moisture control system that performs for the life of your Butler building roof.
UL Class 90 wind uplift rating
The CMR-24 features a UL Class 90 wind uplift rating and offers weathertightness warranties of up to 25 years. This is the highest wind uplift rating available in commercial metal roofing and it means your Butler CMR-24 roof is approved for use in hurricane zones and meets the most stringent performance standards in the industry. Whether your Butler building is located in a high wind coastal area or an extreme weather climate zone the CMR-24 is engineered to hold and stay weathertight for decades.
Energy Star rated cool roof colors
The CMR-24 is available in a variety of Energy Star rated cool colors. Cool roof color options reduce solar heat gain on your Butler building roof surface keeping the building interior cooler in warm months and reducing the load on your HVAC system year round. Combined with the superior rigid board insulation system the CMR-24 cool roof color options give you a complete energy performance package that can significantly reduce your Butler building's long term operating costs and support LEED certification goals.
