What is the keel of the external wall insulation

What is the keel of the external wall insulation

Answer:

External wall insulation does not require keel. Block insulation, inorganic insulation, extruded board and other insulation board these, do not need keel. If the curtain wall is filled with foamed polyurethane, according to the requirements of the curtain wall design keel.
The structure of the insulation must be continuous, can not produce weak links. Between the insulation board can not have a gap, the joints should be filled with styrofoam. If conditions permit, a layer of the ground should also be added insulation.
Light steel keel structure using the form of insulation can be inside the insulation layer of steel temperature and indoor temperature consistent. Steel does not conduct heat does not produce condensate, to avoid corrosion caused by condensate. Second, the light steel keel structure using polystyrene board insulation, the thermal conductivity of less than 80 times the red brick, so as long as the thin board that meet the insulation requirements.
External wall insulation can use light steel keel. Light steel keel structure of the house mainly in the form of external insulation, that is, insulation layer on the outside of the wall. The insulation effect of the house is directly related to the form of insulation, insulation material and structure.
