Why polystyrene foam boards are not good? The right reasons to choose polyurethane foam boards!
2023-05-09

External wall insulation material is one of the important technologies involved in the current field of building energy conservation. It can prevent indoor temperature from escaping through the wall and causing energy waste. As we all know, building energy conservation is a major issue related to the human living environment, so it is crucial to choose the right insulation material.


External wall insulation material


The common external wall insulation materials on the market are mainly divided into the following categories: polystyrene foam board, rock wool board, extruded board and polyurethane foam board. Polystyrene foam board has the advantages of good thermal insulation performance and relatively low price, but it has defects such as poor combustion performance and easy water absorption; in contrast, rock wool board has better thermal insulation performance than polystyrene foam board, and can play a role in sound insulation and fire prevention, which can be regarded as a good performance insulation material; extruded board is a new insulation material in recent years, which has the advantages of not easy to break and low density, but the price is high; polyurethane foam board has excellent thermal insulation performance, but because the odor and organic volatiles generated during foaming have a certain impact on human health, some areas have stopped using it.


So, how to choose the right insulation material? First, considering the thermal insulation performance, it is recommended to use rock wool board, extruded board or polyurethane foam board with excellent performance; secondly, it should be combined with its own needs and budget, and various factors, such as the difficulty of construction, should be considered comprehensively; and then, for users with special requirements such as pure natural requirements, biomass materials or other green and environmentally friendly thermal insulation materials can be selected.


In short, exterior wall thermal insulation materials are an important technology involving building energy conservation and human health. The selection of suitable thermal insulation materials is of great significance to residents' lives and environmental protection.
