Unlike adhesives, PVC caulks are meant to fill gaps and create a water-resistant seal between materials. If bonding is more important, don't use PVC pipe glue, which is often colored blue.
Please be sure to view the specific product's documents for more information. 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.
Proper use of the complete system greatly reduces the possibility of problems and insures that product warranty will be honored. All plastic materials are flammable to some degree, and will catch fire in presence of exterior flame. 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.
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.
Corrugated sheets can be cold arched "along the grain" of the corrugation lengthwise. 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. 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.
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 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. If local recycling is not available, other resources are available. For polycarbonate products, visit The Association of Post Consumer Plastic Recyclers site and review their materials buyers and seller's list.

What considerations are there for fastening Palram products to ACQ treated lumber? Initial tests with ACQ have shown no adverse effect on our fasteners. This is added to the fact that the fasteners are being used to secure a light weight plastic panel rather than connect structural members. If you use Palram fasteners, our 10 year warranty will still apply. Can I paint structural rafters before installing Palram roofing sheets? Do Palram roofing sheets block 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? When roofing with corrugated panels, should I insert screws in the "valley" or at the "crest" of the corrugation? When roofing with corrugated panels, where should I start? However, never start at both sides toward the middle, or at any two separate points. What is the best way to fasten Palram rigid PVC and polycarbonate panels in place?
First, do not use adhesives or caulks that contain silicone when working with PVC. How important is it to follow Palram general recommendations on product usage? Do I really need to buy Palram's recommended fasteners and related accessories? Please see the installation instructions for the specific product for details. PVC and polycarbonate sheets expand with heat, and contract with cold. Always review the specific installation instructions for each Palram product before installing.
Do any Palram polycarbonate products have a UL 94 fire rating? Yes, some Palram products do have a UL 94 fire rating. These solutions are virtually maintenance free as they can endure a wide variety of gases and chemicals for the life of the panel—and under the harshest conditions.
In addition, by using this technology, order minimums can be reduced. This enables metal roll-forming companies to offer matching PALRUF PVC panels for all their products and allows them to capitalize on the growing interest in natural daylighting.

During colder weather, poultry growers should turn their attention to issues that can increase heating costs and hurt bird performance by allowing cold air infiltration and heat leakage. Poultry house sidewalls have been undergoing a transformation from large drop-down curtains to solid, fully sealed and insulated walls. This has dramatically improved environmental control and reduced heating costs.
However, severe air leakage caused by corrosion of exterior metal along the lower sidewall at ground level makes it much more challenging to keep birds comfortable at a reasonable fuel cost. Further, holes provide entry points for rodents and other pests. Pre-drilling the holes ensures that the panels have room to expand and contract properly with temperature changes.
Skipping this step can lead to distorted, warped or cracked panels. Corrugated sheets can be cold-curved to create arched shapes. It's important to follow the relevant Palram specifications for minimum radius in cold-curving, which can be found in the Installation Instructions of the relevant sheets.
In addition, corrugated sheets should be arched so that the corrugations themselves are curved lengthwise. We can provide test reports and other such documents.
Please contact your Palram dealer if you require this data. You can choose to install left to right, or right to left. It is recommended to always advance against the dominant wind direction at the site. Never start at both sides, or at any two separate points. Palram created specific loading tables for each product.
Please visit our website and download the specific catalog. Make sure you start installing from the bottom up so the overlaps will not let the water in. PVC corrugated sheets are mainly used for opaque roofing and siding of industrial buildings in highly-corrosive environments such as port warehouses, cowsheds, and dairies. Polycarbonate corrugated sheets are mainly used as roofing or siding where natural daylight illumination is needed. You may unsubscribe from these communications at any time.
