We manufacture four different kinds of roofing systems to meet all budgets and design criteria.
Roofing system surfaced with ceramic granules:
Fireguard series roofing system:

To streamline your design and selection process, we have selected our high- performance, dual-reinforced (Fireguard SBS), and foil-faced (Metalflex SBS) roofing system below, which addresses most projects. MBTechnology does manufacture other roofing systems, as outlined in our specification manual.
Fireguard SBS Series
Fireguard SBS roofing systems are lightweight, multi-ply roofing systems with exceptional elasticity, puncture-resistance, and low-temperature flexibility. The components consist of a high-grade SBS-modified bitumen blend. The top layer (cap sheet FG(FT)160CWH) has two reinforcements consisting of a fiberglass and polyester mat.
The polyester reinforcement offers superior puncture- and tear-resistance, enabling the membrane to withstand roof movement and traffic. The fiberglass mat at the bottom of the membrane stabilizes the membrane during application.
The Fireguard SBS cap sheet is manufactured with fine ceramic white granules (other colors available on request). This means the system does not require the application of gravel, thereby giving it a light installed weight of approximately 200–240 pounds/100 square feet and making inspection and repair much easier.
The Fireguard SBS roofing system is manufactured with fire-retardant chemicals, qualifying the assembly for the UL Class A/B fire rating over combustible and noncombustible deck. The system is also listed with F.M. (Factory Mutual) to meet I-90 wind uplift. It also meets ASTM D 6162, 6163 standards for SBS-modified bitumen membranes.
Compared with single-ply membranes, which are applied in one layer of 40–80 mils thickness, Fireguard SBS systems are applied in 2–3 ply applications ranging in thickness from 220 mils to 300 mils. The redundancy of multiple layers reduces chances of workmanship error and increases the ability of the roofing system to withstand traffic and numerous penetrations. Fireguard SBS systems consist of a base, ply, and cap membrane (over wood and lightweight concrete), and a 2-ply over-insulated substrate. The system weighs 200–240 lbs/100 square feet, depending on the warranty duration.
The Fireguard SBS system has been marketed for more than 15 years with an excellent track record. It has been applied on various projects throughout the country, and the world, including:
- California National Guard
- Chicago Housing Authority
- Los Angeles Unified School District
- Tracy Army Depot
- Jacksonville Naval Air Station
- Harris County Juvenile Detention Center, Texas
- Port of San Francisco
- San Francisco Civic Auditorium
- University of Washington
- U.S. Bulk Mail Facility, Jacksonville, Florida
- Sheraton Maui
- Diamond Head Health Center
- Port of Vladivostok (far-east Russia).
- L.A. Fitness
Application
The Fireguard SBS roofing system offers the flexibility of three different application methods to meet most job conditions.
Heat Welded:
Ideal for areas where it is impractical to use hot asphalt (e.g., hospitals, schools, high-rises). The heat-welded system offers the owner a 100% SBS system since the adhesive is built in and melted during the heat welding process.
Cold Adhesive:
Minimizes odors during the project.
Hot Asphalt:
The most economical way to apply the membrane. Better suited for new construction and larger projects.
Warranty
Application performed by our network of “Eligible Contractors” qualifies for “Material and Workmanship” guarantee (10-15-20 years). As a condition of this guarantee, we conduct inspections during the application, and a final inspection is conducted to ensure compliance with specifications.
Cool Roof & California Title 24
For projects in California that must meet “Title 24” requirements for “Cool Roof,” the Fireguard SBS system can achieve this by application of an elastomeric coating. Our CSI-formatted specifications address the application of the coating.
Metalflex SBS Series:
Metalflex SBS membranes are manufactured with a top surface of embossed aluminum foil that is laminated during production. Metalflex SBS utilizes the time-proven waterproofing characteristics of SBS-modified asphalt and the protective qualities and reflectivity of aluminum foil. The aluminum surface offers exceptional reflectivity (initial 89% ASTM C-1549) and also qualifies the assembly for a Class A fire rating with no slope restriction, a rating that cannot be achieved with single-ply and asphalt-based roofing systems. The system is also listed with F.M. (Factory Mutual) to meet I-90 wind uplift. It also meets ASTM D6298 standards for SBS- modified bitumen membranes with foil surfacing.
The majority of single-ply and modified asphalt systems have a fire rating limited to a slope of 3:12. The embossed aluminum foil offers exceptional spread-of-flame resistance, which qualifies for a Class A fire rating with no slope restriction. This makes it ideal for projects with a barrel roof or for areas with slopes greater than 3:12.
Whether it is energy-efficient aluminum or bright Polar White surfacing with factory-applied paint finish, the Metalflex SBS foil-faced surface lends a dramatic look to any project.
Compared with single-ply membranes that are applied in one layer of 40–80 mils thickness, Metalflex SBS systems are applied in 2–3-ply applications, ranging in thickness from 220 mils to 300 mils. The redundancy of multiple layers reduces the chance of workmanship error and increases the ability of the roofing system to withstand traffic and numerous penetrations. The Metalflex SBS system consists of a base, ply, and cap membrane (over wood and light weight concrete), and 2-ply over insulated substrate. The system weighs 175–225 lbs/100 square feet, depending on the warranty duration.
The Metalflex SBS system has been marketed for more than 15 years with an excellent track record, with applications and has been applied on various projects throughout the country.
Surfacing
Metalflex SBS is available in two grades, plain aluminum and colored aluminum (white and beige). Custom colors are available on request; please contact us for minimum run and lead-time.
Application
The Metalflex SBS system is applied via heat welding. The heat-welded application eliminates any fumes/odors associated with the application of the membrane.
Warranty
Application performed by our network of “Eligible Contractors” qualifies for our “Material and Workmanship” guarantee (10–15 years). As a condition of this guarantee, we conduct inspections during the application, and a final inspection is conducted upon completion to ensure compliance with specifications.
