There is 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 sure 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.

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. Sometimes, the film also carries necessary installation and other product information.

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

In most cases, we recommend peeling off the protective films after installation. If this is impossible for practical reasons, permanently mark the UV-protected surface, if there is one, so 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 challenging to remove it from the sheet.

Very. Palram recommendations for the storage, installation and general treatment of products are drafted to ensure that the product’s quality and serviceability are met to the full extent, and following these recommendations ensures that the product warranty isn't void. Please be sure to view the specific product's documents for more 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, some Palram products do have a UL 94 fire rating.

All plastic materials are flammable to some degree and will catch fire in the 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 external flame source is removed.

Note that compared to polycarbonate and PVC, acrylic sheets (which are not produced by Palram) are more flammable.

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.

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 to the sheet surface, after which it will be challenging to remove the film from the sheet.

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.

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 of 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 product.

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" before 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 sellers list.
