The roof plays a vital role in both residential and commercial structures as it acts as the first line of defense against external threats and risks. Roofs have been known to exist since man realized the importance of having a shelter to protect them from the elements. Cavemen used earth and vegetation as roofs. Though they were excellent protection from heat and cold, these natural roofing materials could not keep them safe from animals and would easily break due to rains. Over time, man would use different materials as roofing. The Chinese used clay 5,000 years ago. In the 12th Century, Europeans used wood shingles as roofs. Today, roofs are made of different materials like concrete and metal. These transitions were often dictated by man’s desire to come up with the best materials for the protection over their head. And now, thanks to modern technology, more materials or a combination of different materials are being used as roofs. An example is a roof made of Polyurethane Sandwich Panel. But what exactly is it?
Polyurethane may be unfamiliar to you, but it is used in common things around you, like your appliances, cars, shoes, and beds. Polyurethane is a synthetic plastic material with a wide range of uses. Perhaps one of the most familiar items made of this is the flexible foam used in mattresses. It is also used in shoe soles, tires, and as cushioning for furniture.
Polyurethane is popular for the many benefits it offers flexibility, high load capacity, strong bonding ability, range of hardness, and economical manufacturing process. It is also known for its resistance to abrasion and tear as well as water, oil and grease, mold, mildew, and fungus. Because of these qualities, it is widely used in different consumer and industrial products that make our lives comfortable. In construction, it can be used as roofing, particularly as Polyurethane Sandwich Panel.
Polyurethane Sandwich Panel or PU Panel is a structure made of polyurethane foam “sandwiched” between two side skins made of another material such as metal. The foam in between provides thermal insulation. The combination of the materials offers benefits such as its lightweight, durability, and resistance to corrosion and weather elements. All these benefits make the Polyurethane Sandwich Panel ideal for roofing.
Union Galvasteel is a roofing manufacturer in the Philippines that offer a wide array of products, including PU Panel roofing or what we call insulated panels. Under our Duratherm brand, we have Roofing PU Panel and Standard PU Panel. These panels consist of a rigid foam insulation layer sandwiched between two structural metal skin surfaces. The core consists of Polyurethane and Polyisocyanurate insulated panels that form a strong bond to the outer skin, creating a durable panel.
Our PU panels are structurally superior to traditional wood framing as they are stronger and less susceptible to shifting. They are extremely durable, which is important in roofing as roofs are expected to protect a structure and the people inside it from external threats such as bad weather. Though lightweight, it is important to note that PU panels can be as strong as a rock, making them a Well-Recommended Roofing Material for homes or commercial structures.
Aside from durability, PU panel roofing provides other great advantages. First, installation is hassle-free. It requires less time and less manpower install. Second, it is flame-retardant. Its efficient thermal insulation keeps the roof from absorbing too much heat. Third, it is economical. Factoring in the first two advantages mentioned, PU panels can save you money as they are easy to install, while it being flame-retardant means less consumption of electricity. Last but not least, it is eco-friendly. All the materials use in a PU panel are recyclable.
Our insulated panels are also pre-painted in different colors – red, blue, brown, white, beige, and green. Our white variant is USDA approved coating with a Solar Reflectance Index (SRI). Surely, you will find a color that suits your structure’s aesthetics or your personal choice.
Our PU Panels are not only for roofs. They are also ideal for walls, partitions, and ceiling of building structures. Because of the thermal insulation they provide, they are also great for cold storage for food, commercial chillers, pharmaceutical products storage, and controlled-temperature rooms.
