Unique Details That Make the Butler MR-24 the Industry Gold Standard

When it comes to metal roofs, the Butler MR-24 stands out as a leader in the industry. Introduced in 1969, this roof system has been installed over more than 2 billion square feet worldwide. But what makes it the go-to choice for so many builders and owners? Let's dive into the unique details that set the MR-24 apart.

Built to Last

The MR-24 isn’t just another roof; it's a long-term investment. With a life expectancy double that of most conventional roofs, MR-24 can offer you several worry-free decades. This isn’t just a claim; it’s backed by real-world performance and testing. There is a reason the MR-24 is the gold standard of the industry.

Precision Engineering

One of the secrets to the MR-24’s success is its precision engineering. Every panel and structural member is factory-punched to ensure perfect alignment. This precise fit not only adds strength to the roof but also allows it to flex with temperature changes, reducing the risk of damage over time.

The Pittsburgh Double-lock Seam

At the heart of the MR-24’s design is the Pittsburgh double-lock seam. This feature creates a continuous, weathertight seal, finishing the job on-site with a portable seaming machine. This is the same type of seam you’ll find in a Coke can. Needless to say, it’s effective in keeping water out.

Clip Design for Movement

Unlike traditional roofs, the MR-24 system uses clips that allow the panels to expand and contract with temperature changes. This flexibility minimizes stress, preventing leaks and wind damage, ensuring the roof remains strong and intact through all kinds of weather.

Energy Efficiency

MR-24 is not only sturdy but also energy-efficient. With insulation options up to R-40, it provides exceptional thermal resistance, meaning it keeps buildings cooler in summer and warmer in winter. This can lead to significant savings on energy bills and a more comfortable indoor environment.

Sustainable and Eco-Friendly

The MR-24 roof system is material efficient and recyclable, making it an environmentally friendly choice. It’s designed to be low-maintenance and long-lasting, reducing the need for replacement and repair. Additionally, its roof color finishes reflect sunlight and heat, contributing to a reduction in energy consumption and supporting LEED® certification for green building standards.

Wind Uplift Resistance

Designed to withstand severe weather conditions, the MR-24 roof system has earned the highest rating for wind uplift resistance, Class 90. This makes it the reliable choice in areas prone to strong winds and storms, providing added protection and peace of mind.

Leak Protection with Staggered Panel Splices

The MR-24 design features staggered panel splices, which enhance its leak protection. This thoughtful design prevents the common issue of four corners meeting at one point, a typical weak spot in conventional roofs. By offsetting these splices, MR-24 virtually eliminates this vulnerability.

Weathertight Roof Curbs

The system's roof curbs are designed to be weathertight, with internal flange systems that reduce the potential for water infiltration. This attention to detail in every component ensures that the MR-24 roof system remains secure against the elements.

A Complete System

The MR-24 isn’t just a standalone product; it's part of a comprehensive Butler system that includes wall and structural solutions. This integration ensures seamless construction and optimal performance of the entire building envelope.

Trusted Warranty

Confidence in the MR-24 system is backed by a 25-year warranty for paint finish and weathertightness. This warranty reflects the system's proven track record and Butler's commitment to quality and customer satisfaction.
