Why do I have to predrill fastener holes?
Predrilling the holes insures the panels will have room to expand and contract properly with temperature change. Skipping this step can lead to distorted or warped panels. Please be sure to read the installation instructions located on the specific product's document page.
Do Palram products keep the "heat" out?
Palram products are available in a variety of colors (varies by product), each with its own heat and light transmission properties. While all Palram panels block virtually 100% of harmful UV radiation, there are variations in heat and light transmission.
Clear panels allow most solar light and heat through while lighter, opaque colors are more reflective. If excessive heat buildup is a concern, our "Solar Control" panels are you're best bet. Please see each product page for more information on color offerings, light transmission percentages and warranty terms.
How long do the panels last?
Palram manufactures a variety of different products for different applications. Most have industry-leading warranties against manufacture-related defects, as well as specific warranties related to the intended use for the product. However, with proper installation and maintenance, we expect our products to far exceed the warranty periods.
Many of our products are engineered to be installed outdoors and are warranted accordingly. Nevertheless, the lifespan of outdoor products can be affected by how well they were installed, as well as environmental factors like air pollution, winds, and erosion by sand particles.
Warranty details can be found in the Downloads tab under the Warranties section at the bottom of the page for each individual product.
Is there a paint that is appropriate for polycarbonate?
Unfortunately we can’t recommend painting our panels. While polycarbonate is a very resilient material, it is potentially sensitive to chemicals contained in many exterior paints. While we can test a paint for compatibility, we have no way of controlling whether a paint manufacturer will remain consistent with their formulas over time.
My building inspector says I need to know your flame spread rating. Can you provide this information?
Yes. We can provide test reports and other such documents. Please contact your Palram Dealer if you require these data, or Contact Us
. This is technical data and is not to be considered a warranty.
How should I store packed sheets?
Store in a protected, shaded, ventilated site, with no direct exposure to sunlight and winds. In outdoor temporary storage cover with opaque protective film, and avoid PVC films and heat-absorbing materials. Please note: Surface protective films that cover sheets are highly sensitive to heat and direct sunlight. Excessive heat and direct sunlight before taking off the film can cause that film to bond the sheet surface, after which it will not be practically possible to remove it from the sheet!
Why are there polyethylene films on certain sheets and should I peel it off?
The surface films in certain sheets, like Sunlite
sheets, are needed for protection against dirt and scratching, and also used to carry important information to the installer and final customer. The indication of the UV protected side that should be installed facing outwards is extremely important.It is recommended to peel off the protective films only after installation. In case this will not be feasible and the film will be peeled off before laying the sheets, it must be remembered to at least mark the UV protected surface, so that the sheet will not be installed inside out.
wrong installation damages are not covered by Palram.Please also note: Surface protective films that cover sheets are highly sensitive to heat and direct sunlight. Excessive heat and direct sunlight before taking off the film can cause gluing of that film to the sheet surface, after which it will not be practically possible to remove it from the sheet!
Can the sheets be curved?
Yes. Sheets can be cold-curved and serve in arched shapes, provided the relevant Palram specifications for minimum radius in cold curving are followed. These specifications can be found in the Installation Instructions of the relevant sheets.
Solid sheets can be cold-curved in any direction.
Corrugated sheets can be arched so that the corrugations themselves are curved (lengthwise).
Multi-wall sheets can be arched so that the actual ribs will be curved (lengthwise).
Curving is not recommended across the ribs direction.
Do any Palram polycarbonate products have a UL 94 fire rating?
Yes, some Palram products do have a UL 94 fire rating. Please visit the UL 94 Tech Brief
for the most up-to-date information. You may also click here

Do plastic roofing sheets really block UV radiation?
Some of them do. Rigid PVC and polycarbonate sheets are practically opaque to UV radiation, making them a perfect barrier against this harmful radiation. They actually block UV-A and UV-B radiation better than nearly any sunscreen lotion.
On the other hand, acrylic roofing sheets generally transmit a considerable portion of the UV radiation.
If polycarbonate sheets block UV radiation, why is there a ‘UV side’ to face outwards?
Polycarbonate (PC) inherently blocks UV radiation by absorbing it and not allowing it to pass through the panel. However, the absorption of UV also degrades polycarbonate, therefore, the sheet(s) has to be protected against UV radiation. Most Palram PC products feature a very thin co-extruded layer of UV-resistant PC resins that protect the entire sheet from UV radiation. In most cases, UV protection is applied to one side, however, two-sided UV protection is available for select products.
In order to ensure the protection of single-sides UV protected sheets, they must be installed with the marked UV protective layer facing out toward the sun. Although sheet products can also be UV protected on both sides, most of the sheets are protected on one side that is marked clearly.
Can I recycle my old polycarbonate or PVC panels?
Palram's Polycarbonate and PVC sheet products are recyclable. Many cities and towns have recycling programs that include curbside pick-up. If so, Polycarbonate products such as SUNTUF, SUNLITE, PALSUN, DYNAGLAS, or THERMAGLAS should be marked "Plastic #7" prior to recycling. PVC products such as PALRUF, AG-TUF, PALOPAQUE, PALCLEAR, or PALIGHT, should be marked "Plastic #3".
If local recycling is not available, other resources are available:
