You can – and you should! EverClean keeps Palight Trimboard clean all the way from manufacturing through the end of installation.
Think of it as built-in masking. Patch nail holes. Paint around it. Stack, cut, nail, screw, glue, all with the film in place. EverClean can stay in place for up to 30 days after installation – a must for longer jobs.
No. These tapes, used on Sunlite and ThermaGlas products, are for packaging/storage only, and are not strong enough for field service.
After installing multiwall sheets, seal the top end with aluminum foil solid tape, and the bottom end with special ventilating breather tape.
Our three fade-resistant, UV-stable colors – white, sand and clay – go all the way to the core, so painting isn’t necessary. But you can paint it if you want to. No special surface prep is required. Just wipe to remove dust and static.
However, the type of paint you use is VERY important. Always use a "siding safe" paint with a Light Reflectance Value* (LRV) of 55 or higher. Paints with an LRV of less than 55 will absorb more heat, and can lead to damage or warping of any PVC trimboard product, including Palight Trimboard.
NOTE: Please be sure to visit our painting tips page here for detailed information on paint types. You will also find color codes for paints to match our three colors of Palight Trimboard (White, Sand and Clay).
We do not recommend painting our polycarbonate panels. Polycarbonate is a very resilient material, but 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.
Yes, you can paint structural rafters or supports – but be sure to paint only with light or white color. Do not use dark colors like black or brown that can absorb and reflect intense heat.
Yes, Palram's polycarbonate and PVC sheet products are recyclable.
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, PALCLAD PRO HYG, Palclear, or should be marked "Plastic #3".
If local recycling is not available, other resources are available. For PVC products, click here to visit the Vinyl Institute's Recycling Provider Database.
For polycarbonate products, visit The Association of Post Consumer Plastic Recyclers site and review their materials buyers and seller's list.
Palram has one product specifically designed for hurricane protection: Stormlite Multi-Wall Polycarbonate. Review the product page for more information.
Palram's other polycarbonate panels have excellent impact resistance, but the thin gauge of these products makes them inappropriate for this application.
Under no circumstances should you walk, stand or kneel directly on roofing sheets! The risk of breaking the sheets and falling is too great.
If you can't avoid accessing the roof area during installation, always use a crawl board that is strong enough to support the weight of the person. The crawl board must span at least three supporting roof rafters or purlins.
Bending/forming instructions vary by sheet material. Always check the installation instructions of the relevant sheet material.
But in general, some of our sheets can be cold-curved for arched shapes, provided the relevant Palram specifications for minimum radius in cold-curving are followed.
Rigid flat sheets can be cold-curved in any direction.
Corrugated sheets can be cold arched "along the grain" of the corrugation (lengthwise). Corrugated sheets cannot be curved/arched "against the grain." That is, do not bend perpendicular to the direction of the ribs.
Like corrugated sheets, multiwall sheets can be arched only "along the grain" of multiwall (lengthwise).
Our Palight Trimboard "lumber-style" boards can be heat formed in any direction, with the proper heating equipment and forming jig.
Again, see the installation guidelines for each material for specific instructions.
All plastic materials are flammable to some degree, and will catch fire in presence of exterior flame.
The ignition temperature of polycarbonate sheets is 915ºF (490ºC).
The ignition temperature of PVC sheets is 736ºF (391ºC).
Both materials are self-extinguishing, and fire will decay when the exterior flame source is removed.
Note that compared to polycarbonate and PVC, acrylic sheets (which are not produced by Palram) are more flammable.
Yes, some Palram products do have a UL 94 fire rating.

To ensure long-term warranty coverage, it is strongly recommended to use Palram-approved fasteners and accessories, which have been tested to ensure high quality and function.
Palram products + fasteners + related accessories should be thought of as a system meant to provide the best possible installation. Proper use of the complete system greatly reduces the possibility of problems and insures that product warranty will be honored.
Please see the installation instructions for the specific product for details.
Palram products are available in a variety of colors, which varies by product. Each has 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 the 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 your best bet. Please see each product page for more information on color offerings, light transmission percentages and warranty terms.
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 (which are not produced by Palram) generally transmit a considerable portion of the UV radiation.
Review the technical datasheet for each Palram product for specific UV information.
Yes. PVC and polycarbonate sheets expand with heat, and contract with cold.
Various Palram sheet products require different installation and fastening methods to account for expansion/contraction.
Always review the specific installation instructions for each Palram product before installing.
Yes. Suntuf flashing accessories are available in Clear, White and Solar Gray, although they may need to be specially ordered, depending on your retailer.
Corrugated and multiwall panels may be cut with a circular saw (using a very fine-toothed blade made for plastic panels, veneer or plywood). For best results, it is often better to cut just a few corrugated panels at a time to reduce vibration. Clamping the panels also helps. (But be careful clamping multiwall to avoid compression.)
If using a standard circular saw blade, better results may be seen by running the blade backwards (remove and turn it over to reverse direction). Depending on thickness, some panels may also be cut by hand by carefully using tin snips or a utility knife.
For other cutting instructions and further details, please visit each product's document page. You can also view our general Corrugated Products Installation Overview video.
Very. Palram recommendations for the storage, installation and general treatment of products are drafted to ensure that the product’s quality and serviceability is met to full extent, and following these recommendations ensures that product warranty isn't void. Please be sure to view the specific product's documents for more information.
Palram manufactures a variety of different products for different applications. Most have industry-leading warranties against manufacturing related defects, as well as specific warranties related to the intended use for the product.
However, with proper installation and maintenance, our products typically far exceed their 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, sun exposure, winds and erosion by airborne particles.
Warranty details can be found in the Downloads tab under the Warranties section at the bottom of the page for each individual product.
Store sheets in a protected, shaded, ventilated site, with no direct exposure to sunlight and winds. For outdoor temporary storage, cover with an opaque protective tarp, avoiding heat-absorbing materials.
Important note: Palram flat (non-corrugated) panels have a protective surface film that keeps the product safe from dirt and scratches during the long journey from manufacturing to the job site.
These films are 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 be extremely difficult to remove the film from the sheet.
