Abstract
Disclosed is a fastening system and method for securing a sheathing board to an associated framing member. The system includes a feedband for retaining a series of fasteners and a powered drill for sequentially driving the fasteners. The feedband is made from a membrane of a polymeric compound. As the fastener is driven into the sheathing board, a portion of the membrane tears away from the surrounding feedband and becomes seated beneath the fastener. This acts to seal the penetration point and prevent water intrusion and otherwise prevents deterioration of the sheathing board.
Claims8
A method of sequentially driving a series of fasteners into a sheathing member with a power tool, the sheathing member including a first polymeric material, the series of fasteners being initially retained in a feedband, the feedband including a number of interconnected membranes, with each membrane securing an associated fastener, the membranes comprising a second polymeric material, the method comprising:
- advancing the feedband such that a selected fastener can be driven by the power tool;
- rotating the selected fastener by way of the power tool such that it is driven into the sheathing member, the rotation of the selected fastener causing the associated membrane to dislodge from the feedband;
- seating the dislodged membrane within the sheathing member and beneath the selected fastener via continued rotation by the power tool;
- frictionally heating the dislodged membrane to render it dimensionally unstable and thereby cause the first polymeric material and second polymeric material to chemically bond.
A method of forming a water tight seal about a fastener, the method comprising the following steps:
- providing a building board comprising a first polymeric material;
- providing a feedband comprising a number of interconnected membranes, with each membrane securing an associated fastener, the membranes comprising a second polymeric material;
- providing a power tool;
- advancing the feedband such that a selected fastener can be driven by the power tool;
- rotating the selected fastener by way of the power tool such that it is driven into the building board, the rotation of the selected fastener causing the associated membrane to dislodge from the feedband;
- frictionally heating the dislodged membrane to thereby cause the first polymeric material and second polymeric material to chemically bond and form the water tight seal.
