Sleeper Deck Systems

A sleeper system is a buffer between a solid surface and

Style Selections™ decking. Drainage, access and airflow are

critical. Water must be able to flow through and away from the

deck. For repairs and removal of debris, joist system access

is necessary. Good airflow will keep the decking dry and in

good condition.

Style Selections, when used with a sleeper system, must

be supported below its entire length and if used in a roofing

application, the supports must run the direction of the pitch

of the roof to facilitate proper drainage. In addition, sleeper

joists must be attached to the roof structure in a manner that

stabilizes the deck frame. Failure to do so may result in a poor

structure which will compromise deck performance.

In areas of application where a sleeper system is required

that would not be susceptible to excessive debris buildup

(examples would include covered areas such as balconies,

porches, etc.), a minimum height of 1-1/2 in (3.8 cm) for

pressure-treated joists as well as a minimum 1/4 in (0.6 cm)

gap between Style Selections decking would be acceptable.

These areas would still have to be designed to allow for

proper drainage and hidden fasteners would be acceptable.

However, if access to the structure under the decking is re-

quired, it would be recommended to use either the Universal

Fastener (plastic) or 2 in (5.1 cm) composite decking screws.

A 1/4 in (0.6 cm) to 1/2 in (1.3 cm) gap is still required when

abutting walls or other fixed objects.

In all other areas where there could be excessive water

buildup along with debris buildup, Style Selections would

recommend a minimum height of 3-1/2 in (8.9 cm) for pres-

sure-treated joists, as well as a gap of 3/8 in (1 cm). For this

application, hidden fasteners would not be recommended and

standard 3 in (7.6 cm) composite screws would be used.

ALWAYS consult your local building code authority for

proper details on roof and railing installation to the roof

structure if required.

ROOFTOP DECK TIPS

° If you want to access the roof, you must build the

Style Selections deck in removable sections or with

removable fasteners.

° You must attach the sleeper joists to the roof structure

so that they stabilize the deck frame. Failure to do so

may result in a poor structure which will compromise

deck performance.
