1. Reflective heat insulation paint, this is a kind of paint, because it is a paint, so the operation is very simple, as long as it is sprayed on the roof or the wall as a whole, it can effectively insulate the heat, the cost is low, and the service life is 5-8 years. A popular material, the disadvantage is that the life is a bit short.
Its principle is also very simple. The reflective thermal insulation coating is composed of base material, heat reflective pigment, filler and additives. Thermal insulation is achieved by efficiently reflecting sunlight. Thin-layer heat-insulating reflective coatings are representative of this type of coatings.
2. Extruded board (extruded polystyrene board)
Extruded polystyrene board (XPS) is a hard board formed by continuous extrusion and foaming of polystyrene resin. Its interior is a closed bubble structure. Insulation material with good properties such as light weight, long service life and low thermal conductivity. Extruded board application range: Extruded board products are widely used in building roof insulation, steel structure roof, building wall insulation, building ground, square ground, ground frost heave control, air conditioning ventilation ducts, etc.
3. Polyurethane foam material
Polyurethane rigid foam is a new type of polymer material, which has excellent properties of small bulk density, low thermal conductivity, high closed cell rate and corrosion resistance.
Composite panels have the lowest thermal conductivity (≤0.022) among organic thermal insulation materials, and a 5cm-thick composite panel is equivalent to the thermal insulation effect of 1m-thick concrete. Composite board is an ideal thermal insulation product to achieve the goal of 75% energy saving in buildings in my country
Flame retardant: the composite board will not burn through the flame at 1000°C for 30 minutes. Durable weather resistance: The composite board has passed the weather resistance test for more than 6 months, and its performance is stable, which can last the same life as the building. Good dimensional stability: the compressive strength of the composite board reaches more than 200kp, and the board has good temperature resistance and no deformation. Low-carbon and environmental protection: The composite board adopts bio-based raw materials, fluorine-free foaming, does not use harmful substances prohibited or restricted by the state, and is green and environmentally friendly.
4. Rock wool board
Rock wool board use:
Rock wool insulation materials are mainly used for fireproof and sound insulation of building partition walls and curtain walls, insulation of roofs and enclosure structures, and geothermal system insulation; industrial furnaces, ovens, large-diameter storage tanks, and ship insulation and fire protection, etc., but its hygroscopicity is large. , so pay special attention to rain protection, especially in rainy weather
