The insulation and heat insulation of the roof is one of the key points of energy conservation of the envelope structure. Insulate the roof of the cold area to prevent heat loss in the room; set the heat insulation layer on the roof in the hot area to prevent the radiant heat from transmitting to the interior; in the cold winter and hot summer area (Yellow River to the Yangtze River), building energy saving It is necessary to take care of both winter and summer. The common technical measure for heat preservation is to set a lightweight material with a small thermal conductivity under the roof waterproof layer for heat preservation, such as Expanded Perlite, glass wool, etc. (this is a positive paving method); it is also possible to set polystyrene above the roof waterproof layer. Foam (this is the inverted method).
Another type of insulation in the UK is the use of recycled waste paper to make paper fibers. This paper fiber has minimal energy consumption and excellent thermal insulation properties. The paper fibers are fire-retardant after borax flame retardant treatment. During the construction, the nail layer of the roof is first layered, and then the paper fiber is sprayed into the inner layer to form an insulation layer. Roof insulation and cooling methods include: overhead ventilation, roof storage or timed water spray, roof greening, etc. All of the above can meet the requirements of roof energy conservation to varying degrees, but the most respected is the desire to use smart technology and ecological technology to achieve energy-saving buildings, such as solar collector roofs and controlled ventilation roofs.
Polyurethane Insulation Pipeline
Polyurethane Insulation Pipeline, full name: high-density polyethylene plastic outer protective polyurethane foam prefabricated direct-buried thermal insulation pipe, which is composed of a working steel pipe for conveying the medium, a polyurethane insulation layer, and a polyethylene plastic outer protective pipe, which are combined outwards through the equipment in turn.
