Flame retardant effect and performance advantage analysis of extruded sheet

Flame retardant extruded board can stand out in many insulation materials, it must have its own advantages, below we will take a look:

First, with the life of the building, there is no need to carry out secondary construction.

The flame retardant extruded board can effectively buffer the stress caused by structural deformation due to temperature changes, avoid the structural damage caused by rain, snow, freeze-thaw, dry and wet cycles, and reduce the erosion of harmful gases and ultraviolet rays in the air. External wall insulation material is the building's coat, withstand the invasion of wind, frost, rain and snow, therefore, choose a stable and durable, can be the same life with the building of the coat in order to avoid the waste of manpower and material resources caused by secondary insulation construction.

Second, save the amount of insulation materials.

Under the condition of achieving the same energy saving effect, the use of extruded panel wall on the external wall can save the amount of insulation materials because the influence of "thermal bridge" is basically eliminated.

Three, conducive to the stability of room temperature

Because the structural layer with large heat storage capacity is inside the wall, when the indoor is subjected to unstable heat action and the indoor air temperature rises or falls, the wall structural layer can absorb or release heat, which is conducive to maintaining stable room temperature.

XPS extruded board has good thermal insulation performance, high moisture resistance, low water absorption, good sound insulation performance, high compressive strength, good dimensional stability and creep resistance. The fire rating of the extruded board can reach B1 level.
