Not all pre-engineered metal buildings (PEMBs) are created equal. While many manufacturers offer quick construction and budget-friendly pricing, Butler goes further—with decades of engineering innovation, unmatched system integration, and field-tested performance. At MAR Building Solutions, we’re proud to bring these high-performing systems to Kansas City businesses that need dependable buildings built to last.
Here are 10 standout features that make Butler buildings the gold standard in PEMBs:
1. MR-24 Roof System: The Industry Benchmark
The MR-24® roof system is the most specified standing seam metal roof in the world, with over 2 billion square feet installed. It features a unique 360-degree Pittsburgh double-lock seam, formed in the field using a proprietary Roof Runner® machine. This creates a monolithic steel membrane that flexes with temperature changes.
- No exposed fasteners
- Accommodates up to 2.5 inches of thermal movement
- UL Class 90 wind uplift rating and Miami-Dade approved
This reduces stress on seams and fasteners, which are the most common points of failure in conventional roofing systems.
2. Factory-Punched Precision for Flawless Fit
All Butler structural members, roof panels, and wall panels are factory-punched to exact dimensions before arriving on-site. This ensures proper alignment, faster erection, and a tighter building envelope.
| Benefit | Factory-Punched | Conventional PEMB |
| Alignment | Precise | Field-dependent |
| Labor Time | Reduced | Increased |
| Quality Control | High | Variable |
This level of precision minimizes rework, ensures consistent weathertightness, and helps avoid costly delays.
3. Butler-Cote Finish System: Long-Term Appearance and Protection
- Solar Reflectance Index (SRI) of 29 or higher
- Helps reduce heat absorption and cooling loads
- Maintains color vibrancy for decades
Compared to silicone polyester paints commonly used in PEMBs, Butler-Cote offers superior protection and curb appeal.
4. Guarded Hot Box Testing: Verified Energy Performance
Butler built one of the first Guarded Hot Boxes in North America, allowing them to measure the real-world thermal performance of their assemblies. Most PEMB providers rely on theoretical values or individual material ratings.
- Butler EX Wall Systems achieve U-factors as low as 0.046
- Outperform 2.5″ insulated metal panels (IMPs)
- Backed by accredited, in-place testing
This allows engineers to design HVAC systems with better accuracy and efficiency.
5. High-Efficiency Wall Systems with Lower Costs
The Butlerib® II EX and Shadowall® EX wall systems use engineered stanchions to hold insulation securely in place, improving performance and simplifying installation.
- Tested R-values above 21
- Lighter and easier to install than traditional IMPs
- Lower shipping and handling costs
Unlike heavy insulated panels, these systems are easier to work with and still meet or exceed modern energy codes.
6. Leak-Free Penetrations and Engineered Roof Curbs
- Interior-flange roof curbs that move with the roof
- Staggered panel splices that reduce stress points
- Seamed-in gable trim for watertight transitions
All roof accessories are designed as part of the overall system, ensuring compatibility and long-term performance.
7. Long-Term Durability Built In
- Galvalume steel panels resist corrosion
- No exposed fasteners to deteriorate
- Low maintenance and fewer repairs
That translates to significantly lower lifecycle costs and fewer business disruptions.
8. Business-Friendly Reroof Solutions
- No business interruption during install
- Improved insulation and drainage
- UL 90 and FM Global rated
It’s a sustainable, cost-effective solution for buildings in need of a performance upgrade.
9. Sustainability Without Compromise
- Cool roof finishes reduce heat island effect
- Butler systems can reach R-40+ insulation values
- Low-VOC paint and coatings
With Butler, going green doesn’t mean sacrificing performance or durability.
