The MR-24 Roof System is just that: a system of parts that work together seamlessly to provide the effect of a single, monolithic structure on your building, but with the adaptability to conditions that a system offers.
Precision Engineering
The MR-24 System utilizes structural members and roof panels that are factory punched. This ensures a precisely aligned system, adds durability to the roof, and allows adaptation to temperature fluctuations. Siwek Construction has projects throughout the notoriously tempestuous Midwest, so that durability and adaptability to climate changes is a key component for us in our goal to build the highest quality product possible.
The Pittsburgh Double-Lock Seam: 360 degrees of protection
Most other roof systems rely on a crimped or snap on seam between panels. No other system utilizes a 360 degree seam. The Butler MR-24 uses a seam that is completed in the field, with the final 180 degrees rolled over with a portable seaming machine. The resultant “Double-Locked” seam is the same type of seal used on automotive gas tanks, oil drums, and beverage cans. The Pittsburgh Double-Lock Seam easily provides the best weatherproofing of any system on the market, and has led to roof life cycles of over 50 years on many a Butler Building.
