Product Spotlight: Modified Bitumen Roofing Designed for Reliable Performance
When durability, consistency, and long-term performance matter, modified bitumen roofing continues to be a trusted solution across commercial and low-slope applications. Its proven track record, combined with modern manufacturing and reinforcement technology, makes it a practical choice for roofing systems that need to perform under real-world conditions.
Continental Materials’ APP modified bitumen membranes, including APP160 and APP180, are engineered to deliver dependable protection while supporting efficient installation and system integrity. These products are designed for contractors and specifiers who value predictable performance and materials that work as intended on the roof.
Understanding APP Modified Bitumen
APP modified bitumen membranes are asphalt-based roofing sheets modified with atactic polypropylene. This modification enhances the membrane’s physical properties, improving flexibility, heat resistance, and overall durability when compared to traditional asphalt roofing materials.
APP membranes are commonly used in low-slope and commercial roofing systems where long-term waterproofing and weather resistance are critical. When properly installed as part of a complete roofing assembly, they provide a resilient barrier against water infiltration and environmental exposure.
Reinforced for Strength and Stability
Both APP160 and APP180 are reinforced with non-woven polyester, which plays a key role in membrane performance. Polyester reinforcement adds tensile strength, tear resistance, and dimensional stability, helping the membrane maintain its integrity under thermal movement and jobsite stresses.
This reinforcement allows the membrane to accommodate expansion and contraction caused by temperature changes while maintaining a consistent, secure installation. For contractors, this translates to a roofing system that performs reliably throughout seasonal cycles.
APP160 and APP180: Options for System Design
Continental Materials offers APP modified bitumen in different weights to support a variety of system designs and performance requirements.
APP160 provides a balance of flexibility and strength, making it suitable for many standard modified bitumen roofing applications. It supports dependable waterproofing while remaining workable during installation.
APP180 offers increased membrane mass, providing additional durability and robustness for systems that demand enhanced performance. The added thickness contributes to improved resistance to wear and long-term exposure.
By offering multiple options, Continental Materials allows specifiers and contractors to select the membrane that best aligns with the specific needs of the project.
Designed for Torch-Applied Systems
APP modified bitumen membranes are commonly used in torch-applied roofing systems. When installed correctly, heat welding creates strong lap seams that form a continuous waterproof surface across the roof.
Consistent membrane composition and reinforcement help support uniform heat application and seam formation. Proper installation remains essential, and following manufacturer guidelines ensures optimal system performance.
Built for Commercial and Low-Slope Applications
APP modified bitumen roofing is widely used in commercial buildings, industrial facilities, and other low-slope structures where reliability is critical. These membranes perform well in environments where roofs are exposed to temperature variations, foot traffic, and long-term weather exposure.
Their durability and adaptability make them a solid choice for both new construction and reroofing projects, especially when a proven roofing system is required.
Supporting Long-Term Roofing Performance
Roofing materials play a significant role in the longevity of the entire building envelope. Selecting membranes that offer consistent quality and predictable behavior helps reduce the risk of premature failure, leaks, and costly repairs.
Continental Materials’ APP modified bitumen products are manufactured with a focus on quality control and performance consistency. When incorporated into a properly designed roofing system, they contribute to long-term protection and reduced maintenance demands.
A Practical Choice Backed by Experience
Modified bitumen remains a relevant roofing solution because it works. It offers a balance of strength, flexibility, and proven waterproofing performance that contractors and building owners continue to rely on.
Continental Materials’ APP160 and APP180 membranes reflect that practical approach. They are designed to meet the needs of professionals who value materials that install efficiently and perform reliably over time.
