Decking Installation Instructions

CUTTING & DRILLING

EverGrain and Envision decking and skirting products will expand and

contract with changes in temperature. The amount of expansion and

contraction will vary depending upon board size and temperature. Smaller

boards will expand less and larger board sizes will expand more. When

installing decking, side-to-side spacing must be a minimum of 1/8" between

adjacent boards.

* End-to-end spacing between boards must be approximately 1/16" for

every 20-degree increment

of temperature difference

between the temperature

during installation and the

maximum expected summertime

temperature in your area.

Butt joints of boards must be

staggered. A sister joist must

be utilized at the butt joint to

provide a greater fastening area.

• Make safety of the workplace the prime consideration. Always wear the

proper protective clothing and safety equipment and adhere to all safety

guidelines contained herein.

• MODIFICATION TO THE BOARD, OTHER THAN AS STATED IN THESE

INSTALLATION INSTRUCTIONS (SUCH AS CUTTING TO LENGTH,

DRILLING FASTENER HOLE, ETC.) MAY COMPROMISE THE

INTEGRITY OF THE BOARD WHICH COULD LEAD TO PREMATURE

DEGRADATION.

• EverGrain and EverGrain Envision ("Envision") is specially made with

natural board to board color variation. Layout and view all boards prior

to cutting and fastening to ensure the desired look is achieved.

• As with all walking surfaces, decking products located in higher trafc areas

may show wear earlier than other areas. Dragging furniture or other objects

across the product will cause surface scratches.

• Discuss any desired material changes, including color issues, with the

supplier prior to cutting or fastening the decking to the structure.

• The weathering process for EverGrain and Envision decking products will

vary due to region, climate, rain, sunlight exposure, etc. Some variations in

decking shade will appear due to weathering that will occur at the supplier’s

yard prior to shipment and due to different lots. For best results, use

material from the same date code (stamped on the bottom of boards)

whenever possible.

• The color of EverGrain and Envision decking products will usually weather

to a lighter shade after several months of exposure to the environment.

Color may vary across proles.

• EverGrain and Envision decking have a more exible feel than wood

primarily during the heat of summer. This is a natural condition that will not

affect the ability of the decking to perform as warranted. For a more rigid feel,

reduce joist span spacing by 4”.

• EverGrain and Envision decking and railing products must be installed

in accordance with the installation instructions. Deviations from these

instructions may result in unsatisfactory performance, create a potential

safety hazard and may exclude coverage of your decking and/or railing

material under the limited warranty.

• EverGrain and Envision decking products must never be applied

directly to any solid surface (concrete, membranes, etc.) or in conjunction

with systems where inadequate drainage or improper ventilation are found.

There must be proper ventilation and adequate air circulation underneath

the deck to promote the evaporation of any water or moisture.

• Fire and other sources of excessive heat may damage EverGrain and

Envision deck boards. Damage caused by re or other heat

sources may include melting, sagging, warping, discoloration, charring,

increased expansion or contraction, accelerated weathering, etc.

• Low-E glass is one potential source of excessive heat because it is designed

to reect more sunlight than traditional glass. This enhanced reectivity

combined with any irregularity in the window glass can concentrate sunlight

onto the deck and cause heat build-up on areas of the deck surface. When

this occurs, damage to EverGrain or Envision decking is possible.

Contact the manufacturer of the product which contains the Low-E glass for

suggestions to reduce or eliminate the reected heat.

• Composite decking will retain heat when exposed to direct or reected

sunlight. Exercise caution if walking barefoot as footwear may be required.

EverGrain and Envision decking have a more exible feel than wood

primarily during the heat of summer. This is a natural condition that

will not affect the ability of the decking to perform as warranted. For a

more rigid feel, reduce joist span spacing by 4". Decking must not be

cantilevered (overhang edge of deck) because structural support is

required. EverGrain and Envision decking products are non-structural

construction products. The decking products must not be used as a

structural member; including joists, load bearing columns, stringers, or

beams.

For best results, add an additional joist at the butt joints to increase

stiffness.

EXAMPLE:

80ºF at time of installation and a

maximum expected summertime

temperature of 100°F equals an end-to-

end spacing of 1/16".

When working with EverGrain and Envision decking products, saw blades and

router bits with carbide tips are recommended. Saw blades must be sharp. The

use of dull saw blades will result in damage to the outer layer of Envision boards.

For best results, use blades with two teeth per inch. To avoid clogging when drilling

holes, frequently remove shavings by raising the drill bit out of the hole.

Modication to the board, other than as stated in these installation instructions

(such as cutting to length, drilling fastener hole, etc.) may compromise the

integrity of the board which could lead to premature degradation.
