Fasteners
• Listed are several suggested fastening
methods. Additional fastening methods may
exist for AZEK Porch.
• Minimum #7 x 2” 305 stainless steel trim
head screw with #17 drill point.
• When using a pneumatic flooring nailer, we
suggest using barbed/serrated 2” stainless
steel cleat “T” nails or “L” cleats.
• For salt water coastal applications, we
suggest using the above minimum fastener
requirements in 316 stainless steel fasteners.
• Please contact fastener manufacturer to
ensure availability, compatibility, and proper
use with AZEK Porch.
Expansion and Contraction
• When fastened properly, AZEK Porch
will demonstrate minimal changes due to
expansion and contraction. The expansion
and contraction encountered may result
in slight gaps which might be noticed at
the ends of boards or in splice joints. Best
practice is to cut and fasten AZEK Porch
boards as soon after cutting as possible.
• Install the boards together tightly at splices
or miters.
• Be sure to fasten ends of boards, splices,
or abutments to building or structure
securely into framing using a screw which is
positioned within 1/2” of each board end or
joint.
• Expansion and contraction are most
significant where extreme temperature
change may exist.
• For best results, stagger splices and miters
across the porch surface so that all splices
and miters do not break on the same joist.
• To further minimize expansion and
contraction, proper ventilation and air flow
should be considered.
