Composite Decking and local data in Rockville
Composite's main tradeoff is surface heat, and in Rockville sees about 23 days a year at 90°F or above. Color can be chosen mostly on looks, though full-sun decks still run cooler in lighter tones.
About 72 wet days and 72 freeze-thaw days a year make moisture-resistant capped boards a practical advantage over unsealed wood.
With 39% detached homes, many projects in Rockville re-deck an existing frame, so joist spacing must be checked against the board's span rating first.
