Storage & Handling
• Store TimberTech AZEK Deck, Porch, & Rim Joist 
Covers on a flat and level surface.
• Store products in a cool, shady area prior to 
installation.
• Do not stack bundles over 8 units high.
• Always leave factory applied protective wrap, If 
stored outdoors, the product must be covered with 
non-translucent material.
• Use care when handling product with a forklift as 
forks can easily damage the material.
• If banding is used, use protective corners to prevent 
indents from the bands.
• Avoid storing TimberTech AZEK Deck, Porch, Rim 
Joist Covers, & Riser in areas of excessive heat.
Considerations
• Depending on environmental conditions, TimberTech 
AZEK Deck, Porch, Rim Joist Covers, & Riser colors 
may appear to lighten over time as part of the 
natural weathering process.
• Please be aware that excessive heat build on the 
surface of AZEK products from external sources 
such as, but not limited to, fire or reflection of 
sunlight can potentially lead to damage. For 
example, sunlight which may be reflected by low-
emissivity (Low-E) glass can potentially lead to 
damage of exterior building products, including 
AZEK Deck, Porch, & Rim Joist Covers, Riser, Trim, 
Moulding or Railing products, due to elevation of 
surface temperatures which far exceed that of 
normal exposure of the same materials to direct 
sunlight. Possible damage by such reflected 
concentrated light may include melting, sagging, 
warping, distortion, surface discoloration, increased 
expansion or contraction, and unusual weathering.
• Static build-up is a natural occurring phenomenon 
that can occur with many plastic products including 
PVC Decking. It could occur with AZEK products 
under the right environmental conditions. The 
buildup or generation of static electricity is a 
naturally occurring phenomenon in many plastic 
based products such as carpeting, upholstery, and 
clothing, and can occur on alternative decking 
under certain environmental conditions and is not a 
product defect.
• Although AZEK Deck & Porch products are cooler 
to the touch than many other deckboard products 
in similar colors, all decking products will get hot in 
the sun. Additionally, the darker the decking color, 
the hotter it will feel.
• Always remove jobsite dust, clay, dirt, mud, and 
other construction products from AZEK Deck, Porch, 
Rim Joist Covers, & Riser quickly. Do not allow 
construction dirt and debris to sit on the AZEK Deck/
Porch surface.
• IMPORTANT: Do not allow airborne dust from 
concrete, fiber cement siding, landscape blocks, or 
any masonry product to accumulate on the AZEK 
Deck, Porch, Rim Joist Covers, & Riser surface as it 
may damage the surface of the deck. Do not cut any 
product on or near AZEK Deck, Porch, & Rim Joist 
Covers.
