Hyload Inc. 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, waterproofing and masonry flashing 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.
This specification includes Hyload S/A WD Membrane which is a composite waterproof flashing membrane used in all flashing applications. This membrane designed to be used in soft joints at relief angles, or where sealants will come in contact with the drip edge area of the flashing membrane. The Hyload S/A WD Membrane can be used with the Hyload Cloaked Flashing System's three dimensional pre-formed shapes (cloaks).
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.
