Insulation for Prefabricated Panel Houses

Insulation for prefabricated panel houses can be achieved through methods such as floor, foundation, ceiling insulation, and secondary floor covering.

Floor Insulation: For prefabricated panel houses, the areas between the “earth platform” frames formed by the horizontal load-bearing structures are key for insulation. Thick flame-retardant extruded polystyrene foam insulation boards (XPS) can be filled and fixed for insulation. These insulation boards have good thermal insulation properties and can effectively prevent heat loss through the floor. Their flame-retardant characteristics also enhance the safety of the house. During the filling process, ensure that the insulation boards are firmly fixed to avoid looseness that could affect the insulation effect.

Foundation Insulation: On the outer wall surfaces of the “underground elevated foundation” of the overall structure, wrap flame-retardant extruded polystyrene foam insulation boards (XPS). Since the foundation part is in direct contact with the soil, heat is easily conducted away through the foundation. Wrapping insulation boards can effectively reduce this heat loss. At the same time, use polyurethane foam material to seal the gaps between each insulation board to prevent heat leakage from the gaps and further improve the insulation performance.

Ceiling Insulation: Fill glass wool or rock wool within the structural frames of the ceiling. Both materials have good thermal insulation and sound-absorbing properties. After filling, seal with plastic film. The plastic film can act as a moisture barrier to prevent the glass wool or rock wool from getting damp and affecting the insulation effect. Then install the ceiling to achieve good insulation and reduce indoor heat loss to the outside through the ceiling.

Secondary Floor Covering: When rural self-built houses use prefabricated panels, the insulation performance is very poor. Generally, it is necessary to cover the floor with secondary roofing materials to make up for the basic shortcomings of the floor. The secondary roofing is usually laid with slag, lime, and cement. These materials can increase the thermal insulation performance of the floor to a certain extent, reduce indoor heat loss, and improve the living comfort of the house.
