Choosing the Pressure Treated Decking

Dec 9th

Pressure treated decking – Look for ground wood specifically for roof construction, usually indicated as patio terraces. Look for planed wood that cracks, loose knots, knot holes or other defects. Planks cut on the vertical grain which is distinguished by parallel lines of grain are less prone to deform, but are more expensive. The planks cut on the flat grain have more varied patterns which may be preferable. Use pressure treated wood for areas of the structure that will sit within 6 inches of the floor or will have contact with the concrete. Low level decks will be entirely resistant to decomposition or pressure treated wood.

For pressure treated decking substructures, use wood commonly called SPF this means pine spruce or spruce and is the industry standard, which is strong and economical. Choose lumber in sizes and timber graduated in 2 or better, although you can certainly use the top graduated timber. Choose plywood rated performance that qualifies for the sulfuring and underlayment and sorting of either exposure or exterior. Select redwood and cedar wood for roofs and services such as planters and railings. Both types of wood are naturally decay and termite resistant. Choose rating boards of at least 2 or better common for these services.

Choose red wood heart tag for maximum resistance to cavities. Lower grades can be used for planters and other conveniences. Redwood grades common heart building and construction are good choices for the pressure treated decking itself. Choose cedar boards with a high amount of heartwood, indicated by an orange color, for the best resistance to decay. Consider non wood products, which can also be used for roofs, but not for structural components. Made from vinyl or a recycled wood polymer composite, these platform materials resemble wood are long lasting and maintenance free. Feel free to paint the latter, if desired.
