WCP-SF – W-26 – Standard Firm
Standard Firm: 2.75-3oz. Standard-weight Stitchbonded Polyester Fabric with a firm finish. WCP-SF has good strength and elongation. WCP-SF has good conformability on smooth or semi-smooth surfaces. WCP-SF works well when used over smooth or cap sheet surfaces. It has fewer stitches per inch which allows for better wetability which requires less brooming. Because it has a firm (starched) finish it will have fewer wrinkles and will lay straighter during application. This is the practical choice for use over most smooth or cap-sheet roofs. Also known as W-26 or TieTex T-326 Firm.
