SIGA Corvum 30/30 Corner and Angle Penetration Tape

Width: 30/30 or 1.2″

Length/roll: 82′ 

The single-sided high-performance adhesive tape Corvum 30/30 is suitable for permanently airtight sealing of any inside or outside corner created within the envelope. Corvum 30 can be used for timber frame purlins, joists, and skylights, to the basic 90 degree joints between walls, wall and floor, and wall and ceiling. Corvum can be easily, quickly and reliably applied because it is uniquely prefolded with 2 30mm (1 1/8") legs. One leg has the backing paper already removed making it a simple matter to lay an inside corner without any fuss from the tape getting stuck in the wrong place as your trying to place it. Can be applied to any wood substrate and most foam boards.
