LifePine® Siding Installation Instructions
Be sure that the walls are smooth, without protuberances. Nail ends or points should be removed or pounded flush.
An approved paper should be applied over the sheathing. Apply it horizontally, starting at the base of the wall, with a 2″ horizontal overlap on each succeeding course, and a 6″ overlap vertically when starting a new roll. Wrap the paper 4″ each way around both inside and outside corners.
Install corner boards (See Below) at this time.
Flashings and caulking over doors, windows, and other points of potential water entry should be in accordance with good building practice.
To determine the number of courses, measure the height of the wall from the lowest part of the foundation.
Divide the height into equal parts, corresponding closely to the recommended weather exposure, but not exceeding the maximum recommended.
Transfer this measurement and the number of courses to a storypole, to layout the courses on all the other walls. Whenever possible butt lines should align with tops or bottoms of windows and other openings. For appearance, the exposure of the final course at the top should match those below.
Nail Placement and Keyway Offset
Nail placement and keyway offset are essential to ensure the performance of LifePine® products. Nails should be placed no more than 1″ above the exposure line of the shake above it. For example, on a 10″ exposure application, nails should be placed no more than 11″ above the butt of the shake. Use only two (2) nails placed 3/4″ from each edge. Keyways should be offset 1 1/2″ in each successive course.
Double the starting course at the base of the wall (Fig. 2). Apply each shake butted to the adjoining shake to allow for shrinkage. (Fig. 4). Offset the keyways, in any one course at least 1 ½” over joints in adjacent courses (Fig. 4).
Use a straight edge, nailing it lightly to the wall with the edge at the butt line (to keep courses straight and level). Check for level every 3 or 4 courses.
This wall application features concealed nailing (Fig. 2), with nails driven approximately 1″ above the butt line of the succeeding course. For shingles up to 7″ wide, place two nails in each shingle 3/4″ from each edge. Because shingles vary in width there should be little wastage. At corners, or at door or window frames, you may have to trim a selected shingle slightly.
For single course application staggering the butt of the shingle from the horizontal line can make an attractive effect. Apply the shingle irregularly at variable distances below (but not above) the horizontal line. Maximum distances are 1 ” for 16″ and 18″ shingles, and 1 ½” for 24″ shingles (Fig. 7).
