Fields Organic Felts

USES: Fields organic felts are excellent underlayments for steep-slope roofing such as 3-tab shingles, wood shakes, and tiles. In addition, these felts can be installed under all types of building materials, flooring, and sidingincluding stucco, aluminum, vinyl, and wood. Fields organic felts are excellent secondary protection barriers against wind, moisture, and other environmental elements.

DESCRIPTION: Fields asphalt saturated felts are made from virgin and recycled wood pulp that is saturated with a premium asphalt, except UK5 KraftFelt. The saturation of the organic felt mat promotes a greater resistance to vapor transmission, a heavier sheet, greater tensile strength, and more resistance to tear when being installed. UK5 KraftFelt is unsaturated and is for certain speciality installations that require a more absorbent sheet.
