It forms part of a waterproofing and anti-corrosion system for color plate roofs, with southern variants offering resistance to temperatures up to 80 degrees Celsius without flow, and northern variants providing flexibility down to -30 degrees Celsius along with an elongation rate reaching 1000%. Materials are selected based on location and time of year to address specific environmental factors such as high thermal conductivity in metal structures. The membrane features a surface layer of colored metal aluminum foil, which contributes properties including moisture resistance, airtightness, heat insulation, tolerance to sunlight and ultraviolet exposure, and corrosion resistance. Installation involves self-adhesion, suitable for both new constructions and repairs, and it meets general standards for non-toxic, environmentally compliant applications without causing substrate corrosion.\r\n<table style=\"width: 100%;text-align: center;border-radius: 8px;overflow: hidden;background-color: #f8fafc\" border=\"1\" cellspacing=\"0\" cellpadding=\"8\">\r\n<tbody>\r\n<tr>\r\n<td style=\"background-color: #eef2f7\">Thickness(mm)<\/td>\r\n<td>1.2 \/ 1.5\/ 2.0<\/td>\r\n<td style=\"background-color: #eef2f7\">Length(m)<\/td>\r\n<td>20 \/ 25<\/td>\r\n<td style=\"background-color: #eef2f7\">Width(m)<\/td>\r\n<td>1.0<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<h3 dir=\"auto\">Product Features<\/h3>\r\n<ul dir=\"auto\">\r\n \t<li>Low solar radiation absorption coefficient of 0.07, enabling reflection of over 93% of radiant heat for thermal insulation.<\/li>\r\n \t<li>Elongation rate of 400-1000%, allowing adaptability to thermal expansion and contraction in metal roofs;

It handled temperatures up to 80\u00b0C without any melting or shifting, and the self-adhesive layer made installation straightforward without needing extra tools. The aluminum foil surface seems to reflect heat well, keeping the interior a bit cooler. It's been six months, and no leaks so far, even after heavy rains.<\/p>\r\n<p dir=\"auto\"><strong>Anna M\u00fcller<\/strong> - Germany <em>Rating: 5\/5<\/em> Applied this to an old factory roof in a coastal area with salty air. The anti-corrosion properties have held up against rust formation around screw holes and joints. It's flexible enough to deal with our cold winters down to -20\u00b0C without cracking. Easy to apply by just peeling and sticking, and it sealed the seams effectively. The roof looks more protected now, and maintenance has been minimal.<\/p>\r\n<p dir=\"auto\"><strong>Li Wei<\/strong> - China <em>Rating: 4\/5<\/em> We installed it on a large agricultural greenhouse in a region with frequent temperature swings. The elongation helped it adapt to the metal expansion without peeling off. Waterproofing worked as expected during monsoon season, preventing moisture buildup inside. The self-healing for small punctures is useful, though we had to ensure the surface was clean before applying. Overall, it extended the usability of our existing roof without a full replacement.<\/p>\r\n<p dir=\"auto\"><strong>Sarah Thompson<\/strong> - Australia <em>Rating: 4.5\/5<\/em> Used this for renovating a sports venue roof exposed to strong UV and occasional storms. The low solar absorption kept the heat down, which is a plus in our sunny climate. It adhered well to curved sections and around vents, providing a tight seal. No issues with corrosion yet after a year, and it didn't require professional help for installation. A solid option for metal roofs in harsh conditions.<\/p>\r\n<p dir=\"auto\"><img class=\"size-full wp-image-962 aligncenter\" src=\"https:\/\/great-ocean-waterproof.com\/wp-content\/uploads\/2025\/12\/customer-feedback_1.webp\" alt=\"customer feedback\" width=\"2245\" height=\"1587\" \/><\/p>\r\n\r\n<h3 dir=\"auto\">FAQ<\/h3>\r\n<p dir=\"auto\"><strong>What is the temperature range this membrane can withstand?<\/strong> The membrane is designed for use in environments from -30\u00b0C to 80\u00b0C, with variants adapted for northern (low flexibility) or southern (high heat resistance) regions. It remains stable without flowing in heat or cracking in cold.<\/p>\r\n<p dir=\"auto\"><strong>How do I install the membrane?<\/strong> Installation involves cleaning the surface, removing the isolation film from the lower layer, and pressing it onto the roof. It's a cold construction process that doesn't require specialized tools or personnel, but ensure overlaps are sealed properly for best results.<\/p>\r\n<p dir=\"auto\"><strong>Does it work on old or rusted roofs?<\/strong> Yes, it can be applied directly over aging or rusted color steel tiles without dismantling the original roof, providing coverage and anti-corrosion protection. Surface preparation is recommended to remove loose debris.<\/p>\r\n<p dir=\"auto\"><strong>How long does it extend the roof's service life?<\/strong> It can extend the life of a color plate roof by 20-30 years through waterproofing and anti-corrosion effects, based on proper installation and environmental conditions.<\/p>\r\n<p dir=\"auto\"><strong>Is the self-healing feature effective for all damages?<\/strong> The self-healing works for minor punctures like knife or nail wounds at room temperature, allowing the material to seal itself. It may not fully repair larger or deeper damages, which could require patching.<\/p>\r\n<p dir=\"auto\"><strong>What surfaces or structures is it compatible with?<\/strong> It's suitable for metal roofs, including curved or arched shapes, joints, screw holes, eaves, pipes, and vents. It's commonly used on factories, warehouses, agricultural facilities, and solar installations.<\/p>\r\n<p dir=\"auto\"><strong>Is this product environmentally friendly?<\/strong> The membrane is non-toxic and doesn't corrode the substrate. It complies with general environmental standards, but check local regulations for disposal and application in sensitive areas.<\/p>\r\n<p dir=\"auto\"><strong>How does it perform in UV-exposed or coastal environments?<\/strong> The aluminum foil surface provides resistance to sunlight, UV light, and corrosion, making it suitable for coastal or high-UV areas. It reflects over 93% of radiant heat to reduce solar absorption.<\/p>\r\n<p dir=\"auto\"><strong>What if the membrane doesn't adhere properly?<\/strong> Adhesion depends on a clean, dry surface. If issues occur, reapply pressure or use a primer if needed. Test a small area first in variable conditions.<\/p>\r\n<p dir=\"auto\"><strong>Is there a warranty or return policy?<\/strong> Warranties vary by supplier, typically covering material defects for 5-10 years.
