Expansion and Contraction
AZEK Pavers will expand and contract with temperature change (similar to other composite materials).
Below is a table with measures to account for this expansion.
Extreme Heat Warning
Be aware of excessive heat on the surface of
AZEK products from external sources, such as but
not limited to, fire or reflection of sunlight from
energy-efficient window products. Low-emissivity
(Low-E) glass can potentially harm AZEK
products. Low-E glass is designed to prevent
passive heat gain within a structure and can cause
unusual heat build-up on exterior surfaces. This
extreme elevation of surface temperatures, which
exceeds that of normal exposure, can possibly
cause AZEK products to melt, sag, warp, discolor,
increase expansion/contraction, and accelerate
weathering.
Current or potential AZEK customers that have
concerns about possible damage by Low-E glass
should contact the manufacturer of the product
which contains Low-E glass for a solution to reduce
or eliminate the effects of reflected sunlight.
Excessive Construction Debris
It is important during construction, the Paver
surface stay clear from excessive build-up
of dirt, sand, and dust from tile, concrete,
landscape blocks, or any other masonry
products. If these materials are not removed
immediately, the Paver surface will become
difficult to clean and can potentially damage
the Paver's surface finish.
Do not use AZEK Pavers as a work surface.
If a build-up does occur please refer to
the Care and Cleaning section in AZEK’s
installation guide or website, AZEK.com.
