Frequently Asked Questions

What is the recommended ceiling height when installing Palruf or Suntuf over a grill?
+ -

There no set height. All grills are different and cook at wide range of temperatures. Customers who wish to grill under Suntuf or Palruf must be certain that the maximum temperature above the grill never exceeds 212°F for Suntuf and 122°F for Palruf.

These temperatures represent the maximum service temperature for both products. If the products are subjected to temperatures higher than these, the product warranty will be voided and damage can occur to the panels.

Why does water drip from the underside of my roofing panels?
+ -

This is almost certainly due to condensation buildup on the underside of the panels. The condensation that forms is not a direct result of the Suntuf panels, but rather the surrounding environment in which the panels are installed.

To learn what condensation is, why it occurs, and a few suggestions that can help minimize it, click here to download Palram Tech Brief #5007.

Can I paint structural rafters before installing Palram roofing sheets?
+ -

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.

Do Palram roofing sheets 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 (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.

What is the purpose of the protective polyethylene films on certain sheets?
+ -

The protective films in flat (non-corrugated) Palram sheets are for protection against dirt and scratching during the long journey from manufacturing to the job site. In some cases, the film also carries important installation and other product information.

The film will also indicate which side is UV-protected. This side should be installed facing outwards (extremely important).

In most cases, we recommend peeling off the protective films after installation. If this is not possible for practical reasons, always mark the UV protected surface, if there is one, so that the sheet will not be installed upside down.

Important note: The protective films that cover Palram 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 be extremely difficult to remove it from the sheet.

Do Palram panels keep out heat?
+ -

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.

How do I cut Palram's rigid PVC or polycarbonate panels?
+ -

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.

What is the best way to fasten Palram rigid PVC and polycarbonate panels in place?
+ -

The best way is to use Palram-recommended screws fastened through pre-drilled holes that are slightly larger than the diameter of the screw. Pre-drilling insures that the panels will have room to expand and contract properly with temperature change. Skipping this step can lead to distorted or warped panels.

Whatever you do, never use nails. Unlike wood fibers, which compress when a nail is hammered in, Palram's rigid PVC and polycarbonate panels do not compress. That means there is significant risk of cracking and impact damage in the area of the attachment. Also, nailing the panels in place prevents them from safely expanding and contracting with temperature change, resulting in warping of the product.

For exact hole size guidelines and other important installation instructions, see the documents at the bottom of each specific product's web page.

How important is it to follow Palram general recommendations on product usage?
+ -

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.

Do Palram sheets expand in heat?
+ -
Can Palram sheets catch fire?
+ -

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.

Can Palram sheets be curved?
+ -

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.

How should I store Palram sheets when not in use?
+ -

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.

Can I use any of Palram's products as a hurricane screen?
+ -
How long do Palram PVC and polycarbonate products last?
+ -

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.

Can I recycle Palram polycarbonate or PVC panel scraps?
+ -

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.
