Roof Sheeting

The pitch of the roof is the biggest deciding factor. There are numerous trains of thought on this issue and the decision is based on numerous technical factors. However a very good rule of thumb is the following: 1-5 Degree fall: Concealed fix sheeting i.e. Snaplok or Diamondek 5-8 Degree fall: IBR 8+ Degree fall: Corrugated
Many people enjoy the sound of rain falling on their steel roof. For those who don’t, rain noise can be reduced if a foil and glass fibre blanket is used as the insulation material. This foil and glass fibre insulation blanket is installed between the roof frame and the roof sheeting and it performs two jobs. It keeps your home cool in summer and warm in winter, and it also acts as a sound deadening device, by reducing the amount of noise transmitted through to the inside of your home.
No. Performance of the product will be affected by the different film thickness and UV absorbance capabilities of the backing coat on roofing products, however, there are double sided products available for applications where the reverse side will be visible.
Swarf is the term given to the steel debris arising from cutting or piercing operations, and mostly comprises of fine steel particles mixed with abrasive. However, in this context swarf may also be taken to include any other discarded steel objects such as rivet shanks, nails, screws and nuts, which may come in contact with the roof sheets.

Swarf particles, if left on the surface, will corrode and cause rust stains which will detract from the finished appearance of a project. These stains are often mistaken for early deterioration of the roofing and walling itself.

No. In summer a lightweight roof made from steel causes less heat to be radiated into your home because it cools down faster at night. And in winter, the same steel roof, properly insulated, helps keep the heat inside. This can result in reduced cooling and heating costs.

Polycarbonate Sheeting

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 recommendation ensures that product warranty isn’t void.
To a certain extent. Palram sheets are available in a variety of colors 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 colors are more reflective. In case excessive heat buildup is a concern, we offer several products that outperforms conventional heat/light ratio: Solar-Control sheets, SUNLITE SLT, SUNLITE CL, SUNTUF SMART and more.
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.
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.
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.
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.
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.
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.
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.

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.
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.


When choosing thermal insulation, r-value is the best indicator of performance and is the most important factor.

The r-value represents the insulation’s resistance to heat flow (m².K/W) at a given thickness. The higher the r-value of the insulation, the better its performance will be.
