Here, we will provide you with tips for proper vinyl siding installation. The following are absolute “must-do’s” for every siding installation!
- Installed panels must move freely from side to side. Don’t nail too tightly. Always allow a minimum of 1/32” space between the back of the head and the nailing hem. Space fasteners 12” – 16” apart on center.
- When installing a siding panel, push up from the bottom until the lock is fully engaged with the piece below it. Without stretching the panel, reach up and fasten it into place.
- When finishing the top of the wall perforate the cut edge using snap-lock punch approximately every 8”, ensuring the “tabs” face outward.
- Leave 1/4” clearance at all openings and accessory channel stops. This allows for normal expansion and contraction. When installing in temperatures below 40° F, leave 3/8”.
- DO NOT CAULK the space between the panels and the J-channel, outside and inside corners and any other trims. Do not caulk overlapping joints between siding panels.
- NEVER NAIL THROUGH THE FACE OF THE SIDING! Face nailing is driving a fastener through the panel outside of the center of a nail slot.
- Center fasteners in nail slots. Fastening at the end of the slot will cause permanent damage to the siding panel. If you need to lengthen the nail slot, you can do so with a nail-slot punch.
- Drive fasteners in straight. Nailing at an angle will distort siding panels and cause buckling.
- Be careful not to stretch panels. Apply slight upward pressure until the lock is fully engaged, then secure allowing panels to move freely without strain.
- Overlap horizontal siding panels 1”. Excessive overlap can restrict free movement and cause product failure.
- Use fasteners long enough to penetrate a minimum of 3/4” into the nailable base.
- In residing, furring or removal of uneven original siding may be necessary.
- In new construction, avoid the use of green lumber as the underlayment. Keep in mind that siding can only be as straight and stable as what lies under it.
