The materials are then shipped
by LTL carrier based on the best rate.
Q. What carrier do you use for shipping your panels?
A. Common carrier or our own full-service freight transport company.
Q. How are multiwall panels cut?
A. Use a razor knife or a circular saw with a carbide tipped saw
blade (a triple chip grind tooth design). Always support and clamp
sheets before cutting to reduce vibration. Feed the sheets through
slowly to avoid chipping but steadily to prevent heat build-up.
Q. How do you cut corrugated polycarbonate sheets?
A. A circular saw is best for straight, long cuts. Use either a
vertical band saw or hand-held jigsaw for curved cutting. In all
cases, a fine-toothed blade should always be used. Cutting should be
done at a high speed but low advance rate. If making a pointed turn,
first drill a hole where the two cuts are to intersect and then cut
through the hole. Properly support and clamp sheets to minimize
Q: What is the difference between “corrugated polycarbonate” and
“multiwall polycarbonate” sheet profiles?
polycarbonate is a single layer sheet characterized by either a wave
or box-type profile, similar in design to metal roofing sheets with
“peaks and valleys”. Multiwall polycarbonate is characterized by a
rectangular hollow structure “flutes” that run the length of the
sheet. Multiwall sheets are fabricated in many configurations such
as twin-wall, three-wall, five-wall, and five-wall x-structure.
Q. What type of screw should I use when installing polycarbonate
A. It is important to choose the correct fastener for your specific
application. We recommend using a #12 woodmate screw for wood and a
#12 self-drilling screw for metal, such as aluminum or steel.
(Fasteners should penetrate the roof or wall of your structure by at
least one (1) inch.)
Q. Do I need to use a washer with the screws?
A. Yes, Use at least a 1/2" non-conductive EPDM bonded washer. It is
okay to use a larger washer. (Minimum outside diameter of washer
needs to be 1/2".)
Q. What type of sealant should be used on sheets?
A. Only use a “100% silicone” sealant on polycarbonate sheets.
Silicone sealants do not degrade in sunlight. They resist mold and
mildew and remain flexible, allowing for building movement. Do not
use roofing caulk. Consequences of using incompatible sealant are
inadequate adhesion, too rigid of a bond, and/or the product
contains chemicals that may discolor or damage the polycarbonate
sheet. Check the product information on the sealant label BEFORE
using to ensure compatibility.
Q. What are polycarbonate H- and U-Channels used for?
A. A polycarbonate H-Channel is used to join two multiwall
polycarbonate sheets together, providing a finished, professional
look. A polycarbonate U-Channel is used to cap off the top and
bottom of a multiwall polycarbonate sheet, preventing dust, bugs,
and moisture from entering the flutes.
Q. How can I get my H- or U-Channel to slide onto the sheet?
A. Try rubbing a bar of hand soap or squirting mild liquid dish
detergent on the edge of the multiwall sheet. This will aid in
sliding the profile on. A putty knife may be used to gently pry open
the profile. After the profile has been installed, use a soft wet
cloth to remove any excess soap.
Q. Can panels be nailed into place instead of screwing?
A. It is not recommended to nail sheets rather than screw.
Polycarbonate expands in hot weather and contracts in cold.
Pre-drill and screw panels in place to allow for panel expansion and
contraction with temperature changes.
Q. Is it necessary to pre-drill holes before installing
A. When it comes to the installation of polycarbonate sheets,
pre-drilling is a must! Pre-drilling allows for the sheets to expand
and contract due to changes in temperature. Failure to pre-drill can
result in the sheet warping and/or cracking around the screw.
Q. Are there any products that can help keep heat out?
A. All of AmeriLux sheets are UV protected however that does mean
all sheets will block heat equally. Clear panels will a
Q. How do you clean polycarbonate sheets?
A. A mild household detergents may be used with a soft rag.
Never use aggressive or abrasive cleaning agents or glass window
cleaners; they can chemically attack sheets.
Q. Can you walk on polycarbonate sheets during installation?
A. No, do not walk directly on polycarbonate sheets.
Polycarbonate sheeting is not intended to support the weight of a
person. Use stepping ladders or place crawling boards between two or
more rafters to create a path for walking.
Q. How do I bond
two pieces of polycarbonate sheet together?
sheets can be bonded using various techniques including adhesive
bonding, solvent bonding or mechanical fastening. We recommend using
Urethane Laminating Film if there is a concern about optics. If
optics is not a concern, we recommend GE Silicone RTV108 or GE
Silicone Construction Grade 1200.
Q: What is the difference between direct light and diffused light?
A: Direct light is intense, bright light coming from a single source
one direction. Direct light creates sharp defined, deep shadows and
flattens out three-dimensional detail. Diffused light is a soft
light with neither the intensity nor the glare of direct light.
Scattering in many different directions, diffused light is spread
over and reflected around objects, and does not cast harsh shadows.
Q. What is the better polycarbonate choice for a hobby greenhouse:
Multiwall or Corrugated Polycarbonate?
A. This would depend on what climate you’re in, style of greenhouse,
and whether the greenhouse is used year round. Both multiwall and
corrugated panels are lightweight, durable, and easy to work with.
Both are also UV protected to help prevent yellowing and
deterioration from sunlight. Corrugated panels are less expensive
but the single wall construction offers less heat retention. If you
are looking for more insulation, consider a multiwall panel. The
multiwall construction improves thermal efficiency, making the extra
investment worth the energy savings.
Q: What is LEED?
A: Leadership in Energy & Environmental Design (LEED) is a
third-party building certification process developed by the U.S.
Green Building Council. This green building certification program
recognizes best-in-class building practices and is an
internationally recognized standard for measuring building
sustainability. LEED is a performance-based rating system. The four
levels of certification are: Certified, Silver, Gold, and Platinum.
Q. Do I need special tools to install TRUSSCORE™ Liner Panels?
A. TRUSSCORE™ panels require no special tools or training to
install. The tongue-and-groove interlocking system makes both
vertical and horizontal installation quick and easy. Cut panels
using a fine tooth blade (12 to 16 teeth per inch) with the blade
installed in the reverse direction. Fasten in the center the slots
with a drill/screw gun, leaving a minimum of 1/16” between the back
of the fastener head and the nailing flange to allow for expansion
Q. Are multiwall polycarbonate panels strong?
A. Yes, multiwall polycarbonate is a lightweight yet extremely
durable and impact resistant
plastic. Multiwall panels are 10 times stronger than acrylic and 200
times stronger than glass. The UV-protected surface helps maintain
the panel’s clarity and mechanical properties, offering superior
weatherability. Virtually unbreakable, multiwall polycarbonate is a
versatile solution for a variety of glazing applications.
Q. What can I use to cover the gap at the peak of a post frame
A. A polycarbonate ridge cap is the perfect solution for covering
the point where two roofing panels meet, keeping snow and rain out
of the building while allowing natural daylight to come through at
Q. What is a LEXAPANEL™ Standing Seam Panel?
A. It is a polycarbonate panel with raised edges. A polycarbonate
batten snaps over the raised edge of two adjacent panels to form a
seam. LEXAPANEL™ delivers the strength, weatherability, clarity, and
thermal insulation of the LEXAN™ THERMOCLEAR™ polycarbonate
Q. What is the minimum square footage for ordering LEXAN™
THERMOCLICK™ in special colors?
A. Custom or special colors require a minimum order of 2,730 square
feet or 43 sheets of stock lengths. (LEXAN™ THERMOCLICK™ special
order colors: Yellow, Orange, Red, Green, Purple, SCIR Blue, SCIR
Green, and SCIR Grey. AmeriLux stocks LEXAN™ THERMOCLICK™ in Clear,
Opal, and Blue.)
Q. Which of your products would you recommend for the interior walls
and ceilings of a garage?
A. PVC Liner Panels are lightweight and easy to install. The bright
white panels create a pleasant work space. PVC is highly resistant
to chemicals, moisture, and mold. Virtually maintenance free – never
requires painting or refinishing. Panels wash easily with soap and
Q. Why is there film on the polycarbonate sheets?
A. The masking film prevents scratching and damage of the
polycarbonate sheet during transport, fabrication, and installation.
Q: Should I remove the masking film before cutting a polycarbonate
A: No, the masking indicates the UV protected side which needs to
face outwards - towards the sun. Masking should remain in place to
protect the sheet during all phases of fabrication and installation.
Remove approximately two inches of film from sheet edges before
installing. Remember to remove ALL remaining masking immediately
after installation. Note: To avoid accumulated heat effects, store
sheets in a cool, dry place out of the direct sun. Installing the
sheets with the wrong side out will void the warranty.
Q. What can I do if the film is stuck to the polycarbonate sheet?
A. If the masking film is stuck to the polycarbonate sheet, gently
rub with a soft cloth wetted with a product called Fels-Naptha or
isopropyl alcohol. Pull off the film and follow immediately with a
mild soap cleaning and thorough water rinse. (Fels-Napha is
available at most local hardware stores.) Please do not use other
chemicals or sharp objects to remove the masking!
Q. Where can polycarbonate sheets be purchased?
A. Please call our customer service department at 888-602-4441 and
we can direct you to the nearest distributor.
Q. How do I clean out the debris from the interior walls "flutes" of
a multiwall sheet?
A. When multiwall polycarbonate is cut to size, small particles of
dust or plastic may become lodged in the open flutes. It is
important that this debris be cleared from the flutes before
installation. Remove debris a vacuum or blow out with compressed
air. Do not flush the flutes with water because it may take a long
time to dry out.
Q: Do I need to be concerned about thermal expansion and contraction
when installing my polycarbonate panels?
A: Most Definitely! Polycarbonate panels will expand and contract
due to changes in temperature. Polycarbonate expands in hot weather
and contracts in cold. Figure about 1/32" per foot for 100º of
temperature change with the greatest amount of expansion and
contraction occurring during the Spring and Fall months. Fastener
holes must be oversized to allow for this thermal movement.
Q: What is a daylighting system?
A: In structures, daylighting refers to the controlled admission of
natural light into a building to illuminate the interior space. The
best daylighting systems provide natural light without glare,
delivering visual comfort and well-being. Daylighting systems
promote green building design and can be divided into two main
categories: top lighting and side lighting. Skylights and
translucent curtain walls are examples of daylighting systems.
Q: What is Lumira® aerogel?
A: A dry silica particulate, Lumira® aerogel is a completely
recyclable, lightweight insulation that repels water and retains its
properties under compression. Aerogel particles deliver superior
thermal insulation and light diffusion. Cradle-to-Cradle certified,
Lumira® aerogel is designed to optimize light transmission in
Lumira® aerogel is produced by the Cabot Corporation at its
state-of-the-art manufacturing facility located near Frankfurt,
Q. What are the benefits to filling polycarbonate multiwall panels
with Lumira® aerogel?
A. Multiwall polycarbonate daylighting systems are greatly enhanced
by the inclusion of Lumira® aerogel. Lumira® aerogel increases the
insulation factor, provides superior light diffusion, improves
acoustic performance, reduces solar heat gain/loss, and decreases
Q: How thick is a corrugated polycarbonate sheet?
A: CoverLite® MR9” and MR12” corrugated polycarbonate sheets are
.035 inches thick. LEXAN™ Greca (square wave) corrugated sheets are
.033 inches thick. Corrugated polycarbonate panels make excellent
coverings for a patio, deck, or greenhouse, allowing filtered light
through while providing protection from the elements.
Q: Why is an anti-condensate feature important when choosing a
A: Condensation on the inner surface of a greenhouse covering
reduces light transmission and increases the risk of disease. An
anti-drip or anti-condensate coating reduces surface tension,
encouraging water to condense not as droplets but as a thin layer.
This condensation layer is diverted down the sides of the greenhouse
instead of dripping onto plants. Benefits include fewer diseases,
reduced need for pesticides, and higher quality plants.
Q: How to store and handle Polycarbonate and PVC panels during the
A: Polycarbonate and PVC panels can be stored outside temporarily
in the rain or snow. Stack sheets on a raised platform protected
from the wind. Even though the sun’s strength decreases during the
winter, do not expose stacked sheets to direct sunlight. Cover
with an opaque, protective material. Covering the polycarbonate
sheets will also prevent dirt and debris from entering the flutes.
Ideally, panels should be stored in a dry, well-ventilated, shaded
area. Prior to installation, bring the Polycarbonate and/or PVC
panels inside, lay flat (uncovered), and allow the sheets to
acclimate to the temperature of the room where they will be
installed or in a room with the same climate conditions for a period
of at least 48 hours.
Q: What are closure strips?
A: Typically made of foam or plastic, closure strips are designed
with a profile that matches the configuration of a corrugated panel.
Closure strips seal the opening created where the corrugated
polycarbonate sheet meets a flat surface, filling the gap in
corrugated roofing and sidewall applications. Closure strips provide
a finished, professional appearance and increase the
weather-tightness of polycarbonate corrugated panels by preventing
moisture, insects, and debris from getting under the panels.
Q: Can Polycarbonate or PVC be recycled?
A: Yes, Polycarbonate and PVC are recyclable materials. When
possible, recycling is preferred to disposal or incineration.
Landfill or incinerate in accordance with federal, state, and local
requirements. Collected processing fume condensates and incinerator
ash should be tested to determine waste classification.
