Insulation film is recommended. Thermal insulation film is also called the solar film, and in the modern solar film production technology, mentals such as aluminum, gold, copper, silver are made into multi layer super-insulating mental film layer through vacuum spray plating I recommended 3M of the United states. 3M innovative technology products crystalline optical micro attached with automotive insulation film, using a 240 layer "multilayer optical micro attached film as substrate and applied with nano science and technology to achieve high transmittance, high insulation, high barrier infrared and ultraviolet (UV) effect. Both its quality and effects are good. ,,.
Electrothermal film and reflective film is good. There is a heating electric heating film, It has the following advantages: Electrothermal membrane is coated with a highly reflective metal coating in the bottom of conventional electrothermal?film, so as to improve the efficiency of heat reflection and energy efficiency. It also simplify the construction process of electrothermal membrane heating, make electrothermal membrane heating more energy-saving, lower installation costs. So it is more conducive to the popularization of the application of electrothermal membrane heating.
They are different. Generally, using 2cm plastic extruded board and non-woven reflective film non-woven reflection film can be divided into various kinds: 40 50 60 80g. Now some people also use 0.5cm thick Korea Aoyu XPE reflecting film. It is also very good.
