How does the sandwich panels achieve watertight and airtight?
The sandwich panels produced by our company are made of high-quality raw materials, combined with mature board shapes and scientific installation node design, to create fireproof, thermal insulation, waterproof, weather-resistant, wind-resistant, compressive, sound-absorbing, and sound-insulating panels that meet individual requirements. In one multifunctional sandwich composite panel.
What is a sandwich panel?
Sandwich panel is a new type of building material, which is a self-supporting composite panel composed of a double metal surface and an insulating core material bonded between the two metal surfaces. Used as a building envelope system can make the building have rich expressiveness in appearance.
Sandwich panels are airtight and watertight
Most of the sandwich panels are prefabricated building materials, which are factory prefabricated components. There is no need to nail them during construction, and they only need to be spliced in pairs like building blocks. Leakage points and cold bridges appear on the gaps where the two are spliced. Sandwich panels adopt two methods of edge sealing and construction to solve water leakage points and cold bridges. Edge sealing means that the board is sealed with polyurethane, which can effectively block rainwater leakage and improve water tightness. The structure refers to the staggered groove-and-groove insertion between the plates, and the joints are more tortuous to prevent heat conduction. It adopts a closed cavity waterproof structure, which also has the function of rain screen, avoids capillary water seepage, and achieves the purpose of waterproof and air isolation.
The rock wool sandwich panel adopts hydrophobic rock wool, closed cavity rain screen waterproof structure, and slow rebound sealing strips in the middle seam of the board to effectively block water leakage points. It is an assembled building material with excellent air and water tight performance. It is also one of the few sandwich panels made of environmentally friendly materials in the industry. It has no CFC emissions and can be recycled after dismantling. It is a three-star green building material.
