The Leadership in Energy and Environmental Design (LEED) rating system remains one of the most widely recognized environmental rating and certification systems for construction in the US. Many building owners opt to use LEED or similar rating systems to facilitate energy savings, improve quality of life in their buildings, and to recognize other benefits that environmentally conscious construction can offer.

Kemper’s products have been designed to meet a variety of needs including Environmental and Sustainability rating systems such as LEED. Our Technical Data Sheets (Link) contain information that is important to these rating systems; and proper product selection can help you achieve credits in many areas.

  • Indoor Environmental Quality - Low Emitting Materials credits:  Products with indoor applications such as KEMPEROL 2K-PUR and KEMPERDUR EP-FR have been tested  for compliance with the California Department of Public Health (CDPH) Standard Method to ensure these products can contribute to a healthy and safe indoor environment.
  • Building Product Disclosure and Optimization – Sourcing of Raw Materials: Polyurethane products such as KEMPEROL 2K-PUR, KEMPEROL 2K FR, and KEMPERDUR TC contain a high proportion of bio-based material which not only meet the requirements of the Mandatory Federal Purchasing requirements for bio-based materials, but can also contribute to the bio-based content requirements for LEED.
  • Sustainable Sites – Heat Island Reduction: Many of our waterproofing membranes and coating systems are available in a highly reflective white, or other highly reflective colors designed to maximize the material’s Solar Reflective Index (SRI). These highly reflective products can offer significant and ongoing savings on air conditioning costs, and exceed the requirements for both low-sloped and steep-sloped roofs for LEED.




Over the last several decades, regulations regarding Volatile Organic Compounds (VOCs) have been successful at reducing smog in many cities, but the patchwork of regulations at the National, State and even County levels has often created confusion for anyone attempting to  purchase or apply coatings. Kemper strives to stay ahead of these ever changing requirements to offer VOC compliant materials suitable for all applications. Our 2-component technologies offer ultra-low VOC options for roofing applications while many competing single-component alternatives release substantial VOC emissions while they dry.




In addition to emissions from product curing, there is an increasing focus to the long-term emissions from building products in indoor environments. To help provide peace of mind and to meet current LEED standards, Kemper has tested key products to the most widely accepted VOC emission standard for indoor applications; CDPH Standard Method V1.2.
