Modifying and Removing Breaker Boards
|Top Previous Next|
Breaker boards are popular for use with composite decking. Composites have a tendency to expand as they age. To keep the deck looking good over time, deck professionals use breaker boards. These boards run perpendicular to the deck surface. Breaker boards are used to control expansion by keeping decking the same length.
The deck above shows a breaker board down the center of the deck.

Note: For the No Breaker Board option, the space is the butt joint gap. For other options, the decking gap is the gap between decking and the breaker board itself.
