When considering a roofing solution for your commercial building, the MR-24 roof system by Butler Manufacturing stands out as a premier choice. This standing-seam metal roof system has been a leader in the industry since its introduction in 1969. Below, we explore the many benefits of the MR-24 roof, which has become the most specified standing-seam roof system in the world.
Exceptional Durability and Longevity
The MR-24 roof system is renowned for its durability. With more than 3 billion square feet installed worldwide, it has documented in-place performance of over 40 years, often lasting twice as long as conventional roofs. Key features contributing to its longevity include:
– Pittsburgh Double-Lock Seam: This unique seam is completed in the field with a portable seaming machine, creating a tight, weathertight seal that can withstand the harshest conditions.
– Factory-Punched Components: Ensuring precise alignment, these components help the roof system respond effectively to daily and seasonal temperature changes without compromising structural integrity.
– High-Strength Materials: The roof system uses Galvalume steel, which offers an incredibly long service life – we’ve seen these over 50 years old with minimal maintenance.
Superior Weather Protection
One of the most significant benefits of the MR-24 roof system is its ability to protect buildings from weather-related damage. This system is engineered to provide superior protection against wind, rain, and temperature fluctuations.
– Wind Uplift Resistance: The MR-24 roof system has the highest UL wind uplift rating (Class 90) and is approved for use in hurricane-prone areas.
– Staggered Panel Splices: By offsetting adjacent panel splices, the MR-24 roof system virtually eliminates vulnerable areas that are prone to leaks.
– Weathertight Roof Curbs: Internal flange curbs with interior fasteners prevent water infiltration, ensuring a leak-free roof.
Energy Efficiency
Energy efficiency is a critical consideration for any commercial building. The MR-24 roof system offers high R-value options, enhancing the building’s
thermal performance.
– Insulation Options: The system supports insulation up to R-40 using polyisocyanurate insulation, which improves energy efficiency and reduces heating and cooling costs.
– Solar Reflective Colors: The roof is available in a variety of highly solar-reflective paint colors, which help reduce the building’s heat load and contribute to overall energy savings.
Environmental Responsibility
The MR-24 roof system is designed with sustainability in mind. Its green attributes not only help the environment but may also contribute to earning LEED® certification credits.
– Recyclable Materials: The roof system is made from recyclable materials, reducing its environmental impact.
– Low Maintenance: The durable materials and robust construction reduce the need for frequent repairs and maintenance, minimizing the lifecycle environmental footprint.
Flexible Design and Application
The MR-24 roof system is versatile and can be used for various building designs and applications. Its flexibility makes it an ideal choice for new constructions and retrofit projects.
– Flexible Ridge Design: The ridge design allows for expansion and contraction, maintaining the roof’s integrity over time.
– Integrated Trim and Accessories: All components, including the gable trim, are designed to expand and contract with temperature changes, ensuring consistent performance.
Proven Performance and Warranty
Butler Manufacturing backs the MR-24 roof system with comprehensive warranties, reflecting its confidence in the product’s performance.
– 25-Year Warranty: The MR-24 roof system comes with a 25-year warranty for weathertightness and panel finish protection.
