In recent years, composite
aluminum foil insulation materials have become more and more popular in the thermal insulation building materials industry. They are widely used in the insulation of building roofs and external wall insulation. This is mainly because the <strong>
aluminum foil sheet</strong> blocks the excellent performance of heat transfer and is incomparable to other insulation materials.<br></p>
<p>
It is understood that the energy loss of housing in China is about 50% of the wall, about 10% of the roof, and about 25% of the doors and windows. Therefore, the insulation building materials are particularly important for the national energy conservation and environmental protection requirements. As early as 2007, the state issued the GB50411-2007 "Building Energy Efficiency Engineering Construction Quality Acceptance Specification", which stipulates that after completion of all construction projects, the building energy conservation must pass the acceptance before allowing the subsequent branch engineering acceptance. The promotion of the concept of environmental protection and energy conservation has promoted the rapid development of China's thermal insulation building materials industry, and composite <strong>
aluminum foil insulation</strong> materials have gradually emerged among a wide variety of insulation materials.</p>
<p>
According to a company specialized in the production of thermal insulation materials, the composite <strong>
aluminum foil insulation</strong> material is made of
aluminum foil veneer + polyethylene film + fiber braid + metal coating, laminated by hot melt adhesive, and absorbed by sunlight. Very low rate (only 0.07), with excellent thermal insulation properties, can reflect more than 93% of radiant heat. In general, heat will always run up in the building. When the
aluminum foil insulation inside the wall heats up, the aluminum material has a very low thermal emissivity, which can maintain the indoor temperature well. Compared with insulation materials such as vacuum plates and nano-series insulation blankets,
aluminum foil composites are most satisfactory for the reflectivity and transmittance of radiation. In addition, the composite <strong>
aluminum foil </strong>insulation material adopts the latest rubber and plastic modification technology in the world. The main raw materials are polyethylene and EPDM rubber, which are PVC-free, safe and reliable. The insulation performance of the insulation is based on ordinary rubber and plastic foam materials. It has been comprehensively upgraded and has become an upgraded product of rubber and plastic foam materials.</p>
