Question: 1 / 745

Which of the following is NOT a component commonly associated with BUR membrane application?

Evaporation Coating

In the context of Built-Up Roofing (BUR) systems, the components typically include layers of bitumen, reinforcing fabrics, insulation boards, and sometimes fiberglass layers. Bitumen is a primary material used in BUR applications, providing waterproofing and durability. The insulation board is usually included to enhance thermal performance. A fiberglass layer may be used as a reinforcement within the roofing system to improve its structural integrity.

The component identified as not commonly associated with BUR membrane application is evaporation coating. Evaporation coatings are not a standard part of BUR systems; instead, they are often used in other roofing systems as a method to help with heat management or reflective properties. This distinction is significant because BUR systems rely on their layered construction of bitumen and insulation to create a robust, waterproof surface, while evaporation coatings do not fit within that framework.
