FREQUENTLY ASKED QUESTIONS

Shading coefficient (SC) is a parameter that compares transparent and translucent materials with clear 3 mm glass with 87% LT ׂ(light transmission). The lower the value, the more convenient it is to stay under the material on warm, sunny days. In architectural projects, the SC should usually be between 0.3 to 0.5.

The minimum allowed bending radius of the polycarbonate is 200 times the thickness of the sheet, for example, a 2 mm sheet has a minimum 400 mm bending radius.

There are different white substrates available but in order to achieve a true colored image according to the design, a process of profiling (ICC profile) needs to be done. By using a natural white substrate (a tint which been made with no extra additives), the process of measuring and profiling becomes very simple and fast.

For bullets, BULLETPROOF offers UL 752 protection up to level 6 — protection against automatic weapons firing pistol-caliber ammunition such as an Uzi sub-machine gun chambered in 9 mm.

PALCLAD Pro comes standard in white and off-white. In addition, 10 more colors are available on special order. PALCLAD Pro can be printed on with excellent ink adhesion to surface and print quality.

BULLETPROOF offers forced entry protection equivalent to ASTM F1915-05 Security Grade Level 1-3 — a standard developed to measure impact-resistant fittings in correctional facilities.

Crest fixing is preferred.

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.

A matte surface finish is good if you want to avoid glare within your surroundings.

Multiwall polycarbonate should be used when the key design parameter is thermal insulation. Solid polycarbonate should be used when the key design parameter is acoustic insulation and glass-like appearance.

PVC profiled 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.

SUNTUF Plus profiled polycarbonate sheets provide the best light transmittance and UV light resistance, with exceptional load-bearing and impact-resistance properties. SUNLITE Plus multiwall PC sheets provide the best thermal insulation. In locations where you would prefer thermal insulation to light transmission, you should use SUNLITE Plus multiwall PC sheets.

The diffusion is not defined by the material, but by the diffusion additive that is part of the manufacturing formula. The materials should be selected by their fit to the application (e.g. polycarbonate for thermo-forming or extreme weather). Usually products marked with sign grade and/or diffusion grades have greater light diffusion than others.

Sign faces are usually made from polycarbonate or acrylic. For extreme conditions such as heavy hail, low temperatures, or high temperatures produced when thermo-forming, polycarbonate is probably more suitable. For sign boxes or channel letter cans, PVC, multi-layered PVC and foam PVC can be used.

For use in illuminated signage, PALSUN, PALSUN CS (Coil Stock) and PALGLAS are suitable for the sign face; and PALBOARD, PALOPAQUE, and PALIGHT for the body of the letters or symbols. For print & display, Palram's entire product portfolio can be used based on the specific application. This choice depends on a combination of several parameters, including the cost of the media, its durability, and its suitability for the specific application. Please visit Palram’s Flat sheet application catalog for more information.

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.

PALRAM's polycarbonate products are shielded with a UV protection layer that guards against photodegradation, yellowing, and brittleness. This protects the sheets from the harmful impact of UV radiation and helps to maintain light transmittance and quality for many years. Our products come with a 10-year warranty against loss of light transmittance. Upon special request, we can provide an enforced UV protection layer with a longer warranty.
