When selecting a roof system for your commercial building, it’s crucial to choose one that offers durability, efficiency, and long-term value. Butler Manufacturing provides two outstanding options: the MR-24 roof system and the Butlerib II roof system. Each has unique benefits suited for different needs and budgets. Let’s explore the features and advantages of both to help you make an informed decision.

MR-24 Roof System

The MR-24 roof system is renowned for its superior performance and longevity. Since its introduction in 1969, it has become the most specified standing-seam roof system globally, with over 3 billion square feet installed.

Key Features:

Pittsburgh Double-Lock Seam: The MR-24 roof uses a Pittsburgh double-lock seam (the same you’d find in the top of a Coke can), mechanically seamed on-site to ensure a tight, weathertight seal. This design significantly reduces the risk of leaks, even under harsh weather conditions.

Factory-Punched Components: All structural members and roof panels are factory-punched, ensuring precise alignment and a high-quality installation. This precision helps the roof adapt to temperature changes without compromising its integrity.

Energy Efficiency: The MR-24 system supports insulation options up to R-40, enhancing the building’s thermal performance and reducing energy costs.

Durability: Made from Galvalume steel, the MR-24 roof system offers an incredibly long service life (we’ve seen these 50 years old with minimal maintenance). Its components are designed to withstand extreme weather conditions, including high winds and heavy snow loads.

Environmental Responsibility: The MR-24 roof system is made from recyclable materials and features solar-reflective finishes, contributing to energy savings and potential LEED certification credits.

Warranty: This system comes with a 25-year weathertightness and panel finish warranty, providing long-term peace of mind for building owners.

 

Butlerib II Roof System

The Butlerib II roof system offers an economical solution without compromising on quality and protection. It’s designed for projects with budget constraints, providing excellent value with a lower initial investment.

Key Features:

Quick Installation: The Butlerib II roof system features factory-cut and punched panels, ensuring accurate alignment and easy installation. This reduces installation time and costs.

Deep Corrugation: The 1-1/2-inch deep corrugation makes the Butlerib II panel one of the strongest standard ribbed panels in the industry. This design adds strength and support, allowing it to withstand roof traffic and other stresses.

Lock-Rivet Fastener: The exclusive Lock-Rivet fastener used in the Butlerib II system does not work loose over time, ensuring a secure and durable roof.

Thermal Expansion: Factory-slotted holes allow the panels to expand and contract with temperature changes, reducing stress on the panels and fasteners and extending the roof’s lifespan.

Butler-Cote Finish: All painted panels feature the Butler-Cote finish, made with a 70% Kynar 500 or Hylar 5000 resin. This finish resists chalking and fading, maintaining a vibrant appearance for years. Additionally, “cool roof” colors help improve energy efficiency and may contribute to LEED credits.

Warranty: The Butlerib II roof system comes with a 10-year weathertightness warranty, providing confidence in its long-term performance.

 

Comparison and Recommendations

When deciding between the MR-24 and Butlerib II roof systems, consider the specific needs and priorities of your project:

Durability and Longevity: If long-term performance and minimal maintenance are top priorities, the MR-24 roof system is the best choice. Its superior durability and extensive warranties make it ideal for buildings in harsh weather environments or those requiring minimal upkeep.

Budget-Friendly Option: For projects with tighter budgets, the Butlerib II roof system offers an excellent balance of quality and affordability. Its quicker installation time and lower initial cost make it a practical option for community buildings, churches, and storage facilities.

Energy Efficiency: Both systems provide excellent energy efficiency, but the MR-24’s higher R-value options make it slightly better for buildings where thermal performance is critical.

Environmental Impact: Both roof systems are environmentally responsible choices. The MR-24’s recyclable materials and potential for LEED certification make it a strong contender for green building projects. The Butlerib II also offers sustainable benefits with its cool roof colors and durable finish.

 

Wrapping Up

Choosing the right roof system for your building involves considering various factors, including budget, durability, energy efficiency, and environmental impact. The MR-24 roof system excels in long-term performance and durability, making it a top choice for demanding projects. On the other hand, the Butlerib II roof system offers a cost-effective solution without sacrificing quality, perfect for projects with budget constraints.

By understanding the unique benefits of each system, you can select the one that best meets your building’s needs and ensures lasting value and protection.
