How important is to follow Palram's general recommendations on product usage?
Very. Palram recommendations for the storage, installation and general treatment of products is drafted to ensure that the product’s quality and serviceability are met to the full extent, and following these recommendation ensures that the product warranty isn’t void.
Does Palram's products keep the 'heat' out?
To a certain extent. Palram sheets are available in a variety of colours each with its own heat and light transmission properties. While most Palram sheets block 100% of harmful UV radiation, there are variations in heat and light transmission. Clear sheets allow most solar light and heat through while opaque colours are more reflective. In case excessive heat buildup is a concern, we offer several products that outperform conventional heat/light ratio: Solar-Control sheets, SUNLITE SLT, SUNLITE CL, SUNTUF SMART and more.
How long do Palram sheets last?
Palram supplies individual product warranties against most types of failures. The life expectancy can be as much as 30 years, depending on professional installation practice and environmental factors like air pollution, winds, and erosion by sand particles.
How do I cut Palram's sheets?
Easily. Palram sheets may be cut with either a circular saw (using a very fine blade, e.g. plywood, etc.) or a jig saw. For best results it is often better to cut a few sheets at a time to reduce vibration. Also, if using a toothed circular saw blade, better results may be seen running the blade backwards. Sheets may also be cut by hand by carefully using tin snips or a utility knife. For further information please refer to our product manuals.
What should I use to clean my panels?
Warm water with a mild household detergent should be sufficient to clean Suntuf or Sunlite panels. Wipe off any remained dirt with a soft cloth and wash again. NEVER use a solvent based cleaner (ammonia, etc.). AVOID using sponges or brushes that can scratch the panels surface.
In roofing with corrugated panels, what are purlins and closure strips?
Purlins are cross members running across the rafters of your structure. Closure strips match the corrugation pattern of the panels and are attached to the purlins.
In roofing with corrugated panels, where should I start?
You can choose to install left to right, or right to left, or start at the middle and continue to both sides. It is recommended to always advance against the dominant wind at the site. Never start at both sides, or at any two separate points.
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 gluing of that film to the sheet surface, after which it will not be practically possible to remove it from the sheet.
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. 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 blocks UV radiation by absorbing it. This absorption mechanism might degrade the material, and the sheet has to be protected against it. Protection to the sheet is achieved by coating it with a special material that converts the UV radiation into heat that emits to the external air layer.
In order to protect the sheets, they must be installed with the marked UV protective layer facing outside. Although sheet products can also be UV protected on both sides, most of the sheets are protected on one side that is marked clearly.
