Expand-O-Flash expansion joint covers are an effective, flexible joint closure for a wide variety of standard and special applications.
Style EJ expansion joint covers are 60-mil thick, nonreinforced EPDM or neoprene bellows widely used in roof-to-roof and roof-to-wall cant applications where the use of curbs is not present. Black EPDM has the greatest UV resistance, while neoprene has a better resistance to oils.
