Roofing made of sandwich panels is used not only in private but also in commercial and social construction. Let's take a closer look at what this material is, its main advantages and disadvantages.
Design Features
The panel consists of a rigid frame and a filler with thermal insulation properties. All layers are tightly connected to each other, which ensures high strength and eliminates the presence of cavities inside. The frame is made of metal, often thin-sheet steel, and the fillers are: mineral wool; fiberglass; foam plastic; expanded polystyrene.
Fillers are used depending on the manufacturer and purpose. You can learn more about the design and roofing materials of this type here https://arsenal-center.com.ua/. The steel frame is galvanized and also coated with a polymer coating. Thus, the metal is not only protected from environmental influences but also acquires excellent aesthetic properties.
Panels are manufactured in a wide range of colors and with various decorative effects, allowing for a harmonious completion of a building in any architectural style.
Advantages of Sandwich Roofing
The main advantages highlighted by builders are affordable cost, reliability, and ease of installation. The multilayer panel is very strong, resistant to wind gusts, snow loads, and harsh climatic conditions. At the same time, the material is lightweight, making it easy and quick to work with.
These are ready-made blocks that are simply mounted on the frame, significantly reducing labor costs. Moreover, construction can be carried out at any time of the year, as the structure and materials of sandwich panels are not sensitive to temperature changes and other weather factors. The low load on the rafters increases the building's service life. And if installation technology is followed, the risk of leaks is completely eliminated.
Among the main advantages of the material:
minimal thermal conductivity, which reduces the building's energy consumption;
fire safety – panels do not ignite or spread fire;
high sound insulation – the roof protects from street noise, does not creak, and muffles the sound of falling raindrops;
hygienic and sanitary safety – certified panels have no impact on human health and can be used for children's, medical, and health institutions;
chemical and biological resistance – materials are not sensitive to aggressive environments, not susceptible to fungi, mold, and other pests.
Sandwich panels are produced in a wide range of standard sizes, as well as custom sizes. Moreover, the customer can choose not only overall dimensions but also the thickness of the layers, allowing the roof to be equipped according to any requirement.
Panels are suitable for both simple roofs and structures with complex slopes, and installation can be done with a minimum number of joints. For example, for a summer cottage, you can order sandwiches with a smaller thickness of sheet steel and a lightweight filler. This will reduce the overall load on the supporting system and help save additional money on building a country house. And for a residential house in a cold climate region, on the contrary, you can order reinforced panels with a filler layer thickness of up to 200 mm.
How to Choose Sandwich Panels?
This material is produced by many companies, and the product characteristics can vary significantly. The main parameters to consider when purchasing sandwich panels are: service life; compressive and tensile strength; flammability rating; environmental safety; water absorption level.
All technical and operational characteristics must be specified in the technical documentation, and the product must have quality certificates.
When installing a roof made of sandwich panels, it is very important to follow the technology recommended by the manufacturer. It is also necessary to use high-quality sealants and other consumables. Sometimes, to save money, consumers replace recommended fasteners with cheaper analogues, which leads to a significant reduction in performance characteristics.
Despite the fact that the panels themselves are not demanding on weather conditions, joints and seals will be performed qualitatively only in the absence of precipitation, strong wind, and fog, and at an ambient temperature not lower than +4 °C.
