Spotlight on Johns Manville BUR Membrane Roofing

       

BUR membrane roofing from Johns Manville (JM) is our focus today as we move through our commercial roofing systems series (previous posts covered their EPDM , TPO , PVC , SBS  and APP  membrane roofing). We’ll wrap up our JM spotlight with their liquid applied membrane roofing and then move onto commercial roofing from Firestone. In looking at the history of BUR roofing, Building Enclosure reports built-up roof (BUR) systems emerged in U.S. commercial roofing space in the late 1800s, although “the documented use of bituminous products such as coal tar and asphalt as waterproofing products dates back thousands of years.” BUR roofing solutions at Johns Manville have a track record of 160+ years. What’s more, JM reports that nearly one billion feet of their BUR are fully guaranteed today. Keep reading as we explore more about what BUR membrane roofing offers.

Basics and Benefits
What is built-up roofing (BUR)? The Single Ply Roofing Industry states BUR systems are “composed of alternating layers of oxidized bitumen and bitumen-coated membranes, often called felts or ply sheets.” These sheets are then typically “reinforced with a dimensionally stable, high tensile strength fiber glass mat.” An aggregate or roof coating surface enhances the weathering capabilities of the roof, and the “redundant, multi-ply approach ensures the system provides dependable waterproofing for many years.” Ideal for low-slope roofs, JM describes their BUR membranes as “field-fabricated with layers of bitumen, alternating with plies of reinforcing felts.” Benefits of this BUR membrane roofing include:

  • JM describes BUR as a “highly reliable waterproof membrane”
  • BUR roofs are water-resistant and weather-resistant thanks to their redundant layers
  • Systems are “long-lasting, durable and worry-free”
  • The Asphalt Roofing Manufacturers Association lists thermal performance as another BUR feature, noting their “exceptional resistance to the conduction of heat between the exterior and interior of a building, resulting in noticeable reductions in heating and cooling costs.”
