Duo selvedge technology

For safe installation, SOPRAFIX BASE 630 and 640 base sheets are provided with DUO SELVEDGE, a unique and patented technology from SOPREMA. The first 100 mm (4 in.) of DUO SELVEDGE is self-adhesive, which protects components under the base sheet when the remaining 25 mm (1 in.) surface of the selvedge is heat-welded or sealed with a hot air gun.
