Multi-wall polycarbonate glazing panels are the ultimate product designed for any transparent or translucent outdoor application. They are produced in a variety of thicknesses, each with its own set of specifications and values.

as can be seen in the technical data chart below!

The most commonly used panel are available in 4mm, 6mm, 8 mm,10mm, 16mm, and 25mm.  A range from 5/32 ”  to  1″ in sheet thickness and beyond!

Polycarbonate products provide many advantages, besides looking nice, it’s an attractive and budget-minded alternative for a number of outdoor glazing applications. The most favorable consideration is the flexibility, ease to work with, virtually unbreakable, lightweight, relatively inexpensive compared to glass, weather-resistant, flame retardant, thermal insulating, high-temperature resistance, high impact strength (hail resistance) transparent visibility, and can be special ordered with a special coating which eliminates condensation and water droplets.

Twin wall is the most economical grade of multi-wall sheet available; it comes with a manufacturer 10-year warranty as does triple wall and five wall. Twin wall is readily available in 4mm 6 mm 8mm and 10mm thicknesses. Most pre-fabricated greenhouse kits are manufactured with 6mm ( 1/4″ ). Sheet thickness can be upgraded to meet specific climate weather conditions and local building code specifications.

Installation tip

Polycarbonate panels are supplied with a protective PE film which should be kept on until the sheet is installed. The UV-protected side is to be faced towards the sun and is marked with a white printed film, light blue film or a sticker saying Macrolux multi-wall polycarbonate sheet. Macrolux panels should be stored in an area not exposed to the sun, or indirect heat from the sun, which could make the removal of protective film difficult.

Multiwall Polycarbonate

Multi-wall polycarbonate is an acronym widely used to describe certain types of polycarbonate panels and sheets. Triple wall panel thicknesses are readily available in 8mm, 10mm, 16mm and provide more panel rigidity and more thermal insulation than the thinner twin-wall panels.  The same product characteristics apply to the triple wall as do all polycarbonate panels.

While increasing thermal insulation properties, triple wall, and five wall have good light transmission and are also very flexible to work with. In comparison to glass, it’s still the best glazing product to use for any outdoor glazing project.

It is the most economical grade of multi-wall sheet available; available with the same manufactures warranties, awesome features, and high-grade specifications.

How to cut and work with Polycarbonate Sheets…

Experience teaches us a lot, experience also teaches us what not to do!. For those who have never worked with polycarbonate panels /sheets before there are few tricks of the trade that do come in handy!


Polycarbonate panels can be cut to any size or shape. The best tool to use is a circular saw ( electric or battery ). When using a circular saw it’s best to use a fine-tooth carbide-tipped blade. A standard blade can also be used but not with fine results. When cutting curves and shapes, always use a jigsaw with a fine-tooth blade as well. When cutting, always make your cutting marks with a dark sharpie type of pen, this makes for a dark line that is easily traceable and makes cutting easier. All Polycarbonate sheets come with protective film on both sides. Make sure that when cutting, leave the protective film on, make your cut then peel away before installing.

Blow out the flutes before you tape and install

Make sure to have an air blower handy as cutting always leaves polycarbonate sawdust crumbs that statically cling to the inside of the airspace flutes, blow these crumbs out before installing, otherwise they will be there forever.


Drill with high-speed steel or carbide-tipped drill bit. Drill holes slightly larger than the shaft of the drill bit to allow for expansion and contraction. Never drill the hole too close to the edge of the polycarbonate sheet. its best to drill at least a 1/2 to 1″ in from the edge. If H-channels and U-channels are used drilling on the edge of the panel is not necessary. For outdoor application always use stainless steel or galvanized hex head screws with neoprene washers. Do not overtighten the hex head as this will create dimples on the sheet and will cause leaks over time. Fasten heads of the screw snug to the outer surface of the sheet.


After all, cuts have been made, your ready to install…before handling and installing peel back around 2″ of the protective film on both sides of the polycarbonate sheet. It’s best to use skin-tight gloves to avoid fingerprint smudges as this will be very visible at certain angles. Especially for roof applications. All polycarbonate sheets will always indicate which side goes towards the sun. As soon as it’s installed peel away the protective film. In some cases especially for overhead larger panels, after making cuts, I always remove the protective film on the interior side of the application, making sure I have my gloves on to avoid oily finger smudges. Once I have secured the roof panel in place then I remove the outer protective film.

Structure Support Frame

Polycarbonate Profiles, polycarbonate H-channel, polycarbonate U channel

If you are framing your structure with wood, it is best to have a 3″ wide framing surface wherever 2 polycarbonate panels are joined. If using polycarbonate H channel profiles these are about 3″ wide. If using an aluminum glazing system on top of a wood frame these also are approximately 3″ wide. In order to accommodate a 3″ connector profile whether its polycarbonate or aluminum you can use 3 x 3 glue-lams or sister together/ join together (2) 2×4’s or 2×6’s structural wood members wherever, 2 polycarbonate panels are joined together.


Supporting Profiles

Polycarbonate sheets can be joined using several methods. The most popular and least expensive method is to use polycarbonate profiles like H-channels, these profiles are made of polycarbonate. They are somewhat flexible and can be cut with any type of saw. There are basically two types of H-channels …the standard H channel is a one-piece profile that must be shoehorned into the end of the sheet and the other sheet must also be shoehorned into the other side of the H channel… Joining 2 together. Sometimes this can be challenging especially for long and steep roof applications. Best to have an extra set of hands to help.

The other H-channel is a snap H profile, also made of polycarbonate.Polycarbonate Profiles, polycarbonate snap H-channel, polycarbonate Polycarbonate Profiles, accessories, polycarbonate H-channel, polycarbonate U channel

It’s a two-piece profile, the bottom piece gets screwed to the supporting frame member, and the top piece is snapped into place after the two sheets are set in place although its more expensive than the standard H channel this is by far much easier to work with.

H channels are sold in 24 ft lengths
U-channels are sold in 12 ft lengths

U channels are used for the open ends of the polycarbonate sheet, top, and bottom. All standard panels/sheets come in 4ft and 6 ft widths. U-channels are highly recommended and should be used for all applications. U-channels will help to seal the open ends and prevent dust and little critters from accumulating at the bottom of the panel. In addition, the aluminum tape is also recommended for both ends prior to installing the U-channel. Aluminum tape is available at most big box home centers. The bottom of the panel should have pin-sized weep holes to allow air to dry up any condensation that forms inside the air flutes. Always use both the aluminum tape and the U-channel to seal top and bottom ends.


Always use 100% pure silicone clear caulking on the exterior of each seal especially at the bottom of the polycarbonate panel. A protective bead will help to seal the ends and keep the U-channel from detaching itself from the sheet.

Glazing Tape

Glazing tape is a narrow usually 1/2″ wide x 1/8 or 1/16 thickness and is extremely sticky on both sides of the tape, this is especially useful when attaching polycarbonate to metal frames. This also helps in sealing the panels to the frame and to the glazing top cap to prevent leaks. Polycarbonate Profiles, polycarbonate H-channel, polycarbonate U channel

Highly recommended for all roof glazing applications. When applying glazing tape to any surface its best to spray the tape and the surface with soapy warm water before applying the panel. First, apply the tape onto the frame, then peel back and fold the protective film from the upper side back about 2 inches, this will allow making slight adjustments when setting the panel to its final destination.

Once the panel is square with the frame member and in place then peel away the remaining film from the sticky tape. Now you can put pressure on the panel to seal it against the tape. Once permanent contact is made proceed to screw the cap closures to secure the polycarbonate panel to the frame.  Be aware that glazing tape, once applied, makes it very difficult to shift or move the panel if the tape is not wet.


Cleaning and Storing Polycarbonate Panels

Always use mild dishwater soap with Luke warm water, never use abrasives. Use a soft cloth or sponge then rinse with hose water.. Storing: Polycarbonate sheets should always be stored out of direct sunlight.
