Composite Decks for a Wauwatosa home
Composite boards still sit on a wood frame, and each brand publishes its own joist spacing and gapping rules. Wisconsin’s deck appendix asks for a label showing ASTM D7032 compliance and warns that a composite member may not match the capability of the same size in wood. Ask to see the label on the product you pick.
Name the composite line you like and ask which joist spacing the frame will use.
