Decking and Outdoor Living

I’m often asked, “How much does composite decking weigh compared to pressure treated lumber decking?” On average, composite decking weighs 1.5X or 65% more per board than pressure treated deck boards. Composite decking weight will vary per brand, but with Latitudes brand composite decking you can use the chart below as a guide:

Latitudes Intrepid™ Composite Decking weighs approximately 2.64 lbs/ft. 

• Composite board length: 12' = 31.7 lbs
• Composite board length: 16' = 42.2 lbs
• Composite boardslength: 20' = 52.8 lbs

Latitudes slotted (grooved) composite decking will weigh slightly less than 2.64 lbs/ft, but you can use this weight as general reference.

So when constructing a new composite deck, or if you’re refacing / reskinning an existing deck with new composite lumber decking, make sure you take these weights into consideration when framing. Or in the case of reskinning a deck, you may need to add extra structural support to compensate for the added weight.
