Adhesives & Sealants Compatibility
Although Multiwall / Corrugated Polycarbonate Roofing System resists the majority of widely available adhesives and sealants for roof installations, some of the products are not chemically compatible with Multiwall / Corrugated Polycarbonate Roofing System and are not allowed to be used in installations. For a complete listing please refer to “Recommended Adhesives and Sealants for Palram Polycarbonate Products”, which is available as part of the Multiwall / Corrugated Polycarbonate Roofing System marketing kit or from your local distributor. The list also appears on the Palram global website (www.palram.com). Palram offers compatibility tests for specific sealing materials submitted through an authorized representative.
Weather Resistance
Multiwall / Corrugated Polycarbonate Roofing System will resist all that nature has to offer. Wind will not buckle it. Hail bounces off. Extreme temperatures will not render or brittle it.
Resistance to UV Radiation Multiwall / Corrugated Polycarbonate Roofing System is manufactured with an integrated UV resistant layer that will not separate or peel over time. Accelerated weathering tests in laboratory conditions (2000 hours QUV, equivalent of 20 year of exposure) show a negligible decrease in light transmission, and invisible increase in yellowness index.
Protection from the Harmful Effects of UV Radiation
Exposure to Ultraviolet (UV) solar radiation is a well known and major health concern. In addition to skin cancer, premature aging has been associated with exposure to UV. Multiwall / Corrugated Polycarbonate Roofing System sheets completely block out UV radiation.
A comparison of the UV protection offered by Multiwall / Corrugated Polycarbonate Roofing System and that offered by sunscreen cream 15 is depicted in the graph below. Note that no barrier is as effective as Multiwall / Corrugated Polycarbonate Roofing System sheet. Activity under Multiwall / Corrugated Polycarbonate Roofing System will be more protected than that offered by proper application of sunscreen, though the latter is sufficient in almost all cases.
