The 9,800-square-foot addition project called for a self-adhered, modified bitumen roofing material that the city of Seattle had often used in the past. However, the specified material was quite costly, leading everyone to search for an alternative.
After considering a number of options, the project’s roofing contractor, SQI Inc., decided on PolyKool®, a highly reflective, modified bitumen roofing membrane that is part of Polyglass’ KOOL ROOF SOLUTIONS. PolyKool is an APP-based, modified bitumen membrane that utilizes Polyglass’ patented ADESO® Dual-Compound Self-Adhered Technology.
