What is the difference between xps extruded board and foam board, which is better?
As we all know, XPS extruded board and foam board are the more commonly used insulation materials on the market, but most people do not know the difference between the two, and often get into a dilemma when selecting materials. In response to this problem, this article specially sorts out the difference between extruded board and foam board, hoping to help everyone!
It is understood that our common extruded board is made of polystyrene resin as raw material, and is continuously extruded and foamed through a special process to form a rigid foam board material. Its interior is an independent closed bubble structure, which is a high Environmentally friendly insulation materials with excellent performance such as compression resistance, non-absorption, moisture resistance, airtightness, light weight, corrosion resistance, long service life, low thermal conductivity, etc., are widely used in wall insulation, low-temperature storage floors, parking platforms, airports Moisture-proof and heat preservation in areas such as runways and highways, control ground frost heave, and have excellent heat insulation performance.
The foam board is a white object made of expandable polystyrene beads with a volatile liquid foaming agent and heated in a mold after pre-heating. It has the characteristics of fine closed cells and is mainly used for building walls. Body, composite board thermal insulation, thermal insulation of air conditioners, vehicles, ships, floor heating, decoration carving, etc.
Compared with the two, there are certain differences in cost. Under normal circumstances, extruded polystyrene board is more expensive than foam board. At the same time, there is a certain gap between the two manufacturing processes, and the extruded board is better than the foam board in terms of heat preservation performance.
In addition, because of the raw materials, the strength of the extruded board is higher than that of the foam, and the flame retardant effect of the extruded board is more prominent. Compared with the extruded board, the flame retardant performance of the foam board is relatively poor.
In summary, although both are commonly used in energy-saving building materials, the performance of extruded panels is far better than foam panels as thermal insulation materials.
The above is the difference between XPS extruded board and foam board
