Mac Sheldon

Mac Sheldon has worked in the spray foam industry for 17 years and was an HVAC contractor and distributor before spray foam. Mac filled several roles for Demilec, a large, multi-national manufacturer of spray foam, over 14 years before launching his consulting business in 2014.  His roles at Demilec included Northwest US Territory Manager, Asia-Pacific International Business Manager, Western Region Manager, National Accounts Manager, Director of Engineering, and Director of Training and Industry Communication. His engineering background and his continued study of WUFI, BPI and RESNET protocols have kept Mac tuned to the changing analytical tools available to building professionals for assistance in logical design, appropriate application of spray foam and the need to properly ventilate well-sealed homes and buildings.

Mr. Sheldon served on the Board of Directors of the Spray Polyurethane Alliance (SPFA) for 8 years and served for two years on the Leadership Committee of the Center for Polyurethane Industries (CPI), Spray Foam Coalition (SFC). He is also a Board member for the Cold Climate Housing Research Center in Fairbanks, Alaska.  Through these organizations he is active in development of SPFA applicator certification, building codes and standards development, and general support and promotion of the spray polyurethane industry.

Mr. Sheldon also serves on the Technical Oversight Committee for SPFA and chairs the Industry Advisory Council for the Cold Climate Housing Research Center (CCHRC) in Fairbanks. He led the industry development of the current fire testing protocols for SPF installed in attics and crawlspaces, and remains active in ICC building code development both within the trade associations and individually. He is certified in WUFI, WUFI 2-D, and WUFI-Plus, as well as HERS (RESNET) and is a BPI Building Analyst. Mr. Sheldon speaks regularly at industry events and conferences and is a certified AIA presenter and a contributor to industry publications such as Spray Foam Professional Magazine.  He is also a Certified Supplier Rep in the SPFA Professional Certification Program.

Mr. Sheldon has developed four patents, and spent 15 years as an HVAC contractor in the Northwest before venturing to Asia where he exported US-made mechanical systems for ten years. In the late 1990s, he was consulting for a Japanese company who asked him to find an insulation that would perform to specification under widely varying climatic conditions, including significant wind loads. After a thorough review of available products Mr. Sheldon recommended specific brands of SPF and the Japanese company continues to import the same US-made products today.

Mac’s personal interests include cycling, skiing, camping, woodworking and aviation. He’s an instrument rated private pilot and served on the Mount Hood Ski Patrol for 26 years, where he held executive council positions for 13 years and earned a National Ski Patrol Appointment. When not on the road for the spray foam industry, Mac enjoys life in rural Oregon with his wife of 40 years, their black lab, and a dozen koi.
