Modified Bitumen Roof Systems, also known as MBR, are a popular choice for commercial roofing applications. They provide long-term protection from harsh environmental elements and offer high performance in extreme temperatures. MBRs can be installed quickly and easily, and offer a cost-effective solution for commercial roofs. This article provides an overview of the benefits and features of Modified Bitumen Roof Systems, as well as installation tips and maintenance considerations.
Modified Bitumen Roof Systems are composed of multiple layers of reinforcing fabrics, bitumen, and surfacing materials. They are designed to be flexible and resistant to cracking or splitting from temperature changes. The bitumen used in MBRs is modified with modifiers to increase its durability and resistance to temperature extremes. MBRs are available in a variety of colors and textures, making them an attractive option for commercial roofing applications.
They are also designed to be low maintenance and require only occasional inspections for any damage or wear. MBRs are easy to install and can be applied over existing roofing systems, providing a seamless transition from old roofing to new. This article will provide an overview of the benefits and features of Modified Bitumen Roof Systems, as well as installation tips and maintenance considerations. We hope this article will help you understand why MBRs are a popular choice for commercial roofing applications.
Types of Modified Bitumen Roof Systems
Modified bitumen roof systems (MBR) are a popular choice for commercial roofing due to their durability, affordability and easy installation.There are several types of MBRs available, each with different properties and applications. The most common type of MBR is the SBS modified bitumen membrane. This type of membrane is made from a rubberized asphalt and is reinforced with polyester or fiberglass fabric. It is highly resistant to UV radiation, hail, and other environmental elements.
It is often used in built-up roof systems and can be applied directly to the deck or as a base sheet to a cap sheet. Another type of MBR is APP modified bitumen membrane. This type of membrane is made from a petroleum asphalt base and is reinforced with polyester or fiberglass fabric. It provides excellent flexibility and elongation and is often used in combination with other roofing systems.
The last type of MBR is PE (polyethylene) modified bitumen membrane. This type of membrane is made from a polyethylene base and is reinforced with polyester or fiberglass fabric. It has superior flexibility and elongation characteristics and is usually used as the base layer in combination with other roofing systems. Each type of MBR has different benefits and applications in commercial roofing.
SBS modified bitumen membranes are highly resistant to UV radiation, hail, and other environmental elements, making them ideal for built-up roof systems. APP modified bitumen membranes provide excellent flexibility and elongation, making them ideal for combination roofing systems. Finally, PE modified bitumen membranes have superior flexibility and elongation characteristics, making them ideal for base layers in combination roofing systems.
