What to Do If the House Roof Is Prefabricated Panel

If the house roof is made of prefabricated panels, corresponding measures can be taken for different problems. For example, for heat insulation, roof or indoor heat insulation methods can be selected, and for water leakage, professional treatment is required.

Heat Insulation Measures

• Roof Heat Insulation: If the roof does not require frequent access, a layer of heat-insulating aluminum foil can be applied to the roof. Heat-insulating aluminum foil can effectively reflect the heat from solar radiation, reducing heat transfer to the interior and thus lowering the indoor temperature. This material is simple to install and has a relatively low cost, making it a cost-effective heat insulation method. If the roof requires frequent access, insulating foam glass is a better choice. It has the advantages of pressure resistance, waterproofing, and insect resistance, is easy to install, and has a long service life. Insulating foam glass can effectively block heat transfer, preventing outdoor heat from entering the interior in summer and reducing indoor heat loss in winter, ensuring a warm interior in winter and a cool interior in summer, which is both economical and practical.
• Indoor Heat Insulation: Installing GWS glass wool using a keel frame on the indoor ceiling is also an effective heat insulation method. GWS glass wool has good heat insulation performance, can block heat transfer, and maintain a comfortable indoor temperature. At the same time, it is aesthetically pleasing and has a long service life. Although the initial investment may be slightly higher, its heat insulation performance and aesthetic appeal are worth considering in the long run.

Water Leakage Treatment

When a prefabricated panel roof experiences water leakage problems, it is not sufficient to only treat the surface. Because the interior of the prefabricated panel may be hollow, surface treatment cannot fundamentally solve the water leakage problem. For example, if only waterproofing material is simply applied to the leakage site, water may continue to flow inside the prefabricated panel and seep out from other locations again. The correct approach is to adopt professional methods, such as identifying the source of the leakage, repairing or replacing the prefabricated panel, or using grouting and other methods to fill the voids inside the prefabricated panel, preventing water penetration and thus thoroughly solving the water leakage problem.
