How to Insulate Prefabricated Panel Houses

Insulation of prefabricated panel houses can be achieved through various methods, including thermal insulation construction, the use of foam light steel roof panels, prefabricated renovation, and the application of prefabricated roof insulation integrated panel construction techniques.

1. Thermal Insulation Construction for Prefabricated Houses
   Using materials such as thermal insulation cotton for thermal insulation construction is a relatively direct method. Before construction, tools such as gloves, rulers, protective clothing, masks, and machetes (serrated, for cutting insulation materials) need to be prepared. Taking the gap in the kitchen exterior wall as an example, the width needs to be measured precisely. To ensure that the insulation cotton fits better in the gap, it can be cut half a centimeter to one centimeter wider. For instance, if the actual width of the gap is 52.5 centimeters, it can be cut to 53 centimeters and directly inserted into the middle. If it is cut too narrow, there will be gaps that affect the thermal insulation effect and cause the insulation cotton to bulge.

2. Adoption of Foam Light Steel Roof Panels
   For old houses built in the 1980s, whose roofs are mostly cement prefabricated panels and have problems such as cracking, water seepage, and poor earthquake resistance, as well as for newly built houses, foam light steel roof panels are an ideal choice. They can replace traditional panels as formwork, with simple and convenient construction and excellent post-construction thermal insulation, sound insulation, and other effects. Foam light steel roof panels have the advantages of being lightweight yet strong, corrosion-resistant, and having good fire resistance, effectively improving the overall performance of the house.

3. Prefabricated Renovation
   Giving prefabricated panel buildings a "high-tech coat" means carrying out prefabricated renovation. Contemporary prefabricated buildings are upgraded in terms of materials and connection techniques, adopting a systematic approach to integrate functions such as thermal insulation. Unlike old-style prefabricated panel houses, prefabricated buildings, through factory production and on-site assembly, can improve the poor thermal insulation of prefabricated panel houses while enhancing construction efficiency and quality.

4. Prefabricated Roof Insulation Integrated Panel Construction Technique
   The industrial approach of prefabricating roof insulation integrated panels is adopted, eliminating the on-site construction procedures of the insulation layer and protective layer and replacing them with modular assembly construction. This technique implements full-process control and one-stop management from the production, transportation, and installation of the insulation integrated panels, effectively ensuring the forming quality of the roof insulation integrated panels. Its construction process includes steps such as detailed design, component production, transportation and stacking, and on-site construction preparation. The process is simple, and the installation is fast, which can significantly shorten the construction period of the roof project. In the later stage, it can be partially disassembled and replaced in blocks, facilitating roof waterproofing maintenance.
