CertainTeed, Valley Forge, Pa., launches the new Landmark-WideTrack QB, taking the company's Landmark Series laminated shingle and adding a wider nailing area for greater installation accuracy. A typical laminated shingle has a nailing area of 1/2 inch to 3/4 inch, a space that many contractors complain is too narrow and which can lead to application problems. The nailing area on Landmark-WideTrack QB is 1 1/2 inches, making it easier for contractors to apply shingles correctly and avoid misapplied fasteners, potentially reducing callbacks and improving homeowner satisfaction. In addition to its wider nailing area, the shingle features specially formulated Quadra-Bond adhesive for extra strength and durability to hold the two-piece laminated shingle together. WideTrack QB also features sealant strips on the back of each shingle. This eliminates any chance of nail guns gumming up from sealant that used to be applied on the front of the shingle, on or near the nailing line. Landmark-WideTrack QB is currently available in most areas of the United States.
