Hyload is a U.S. company with its corporate office in Seville, Ohio, and its manufacturing facility located in Wadsworth, Ohio.
Hyload, is part of IKO, a family business operating for more than 60 years providing global manufacturing and supply of quality roofing products including shingles, commercial roofing and asphaltic bituminous waterproofing products.
For the roofing and waterproofing markets, Hyload offers the unique benefit of including coal tar pitch as a key component in our Elvaloy membranes. These Coal Tar Elastomeric Membranes (CTEM) combine the time-tested benefits of coal tar with today's technological advancements. Our roofing line also offers a white membrane to meet the need for reflective roof assemblies, while our masonry flashing membranes offer additional color choices.
Hyload Elvaloy(R) membranes are represented by sales specialist firms in territories throughout the United States. Hundreds of millions of square feet of membrane have been installed since production began in the U.S. in 1982. Our technical service department and customer service personnel stand ready to serve our customers.
