With the improvement of the whole society's awareness of energy-saving, in the field of building energy saving is more and more attention by people. In the aspect of building energy efficiency, exterior wall insulation is one of the current construction technology, it is like to building into a & other; Cotton & throughout; 。 In this respect, the choice of the thermal insulation material is the centre of attention. Exterior wall thermal insulation material should be how to choose? How to ensure the safety in the construction process? This is many people are concerned about the problem.
( 1) Water proofing property is good. Polyurethane composite board has excellent waterproof, steam trap performance, material is not water, bibulous rate is low, can well blocking water and water vapor permeability, make the wall to keep a good and stable adiabatic condition, is currently the other heat preservation material can be difficult to achieve. Around the surface of polyurethane composite board with no seams, holes, the place such as doors and Windows around the hole, make it has a good waterproof performance, avoid dangerous rainwater into the internal.

  ( 2) Building exterior wall condensation. Inside the wall or in the thermal insulation layer is harmful to both internal condensation, in the process of new wall dry, or under the condition of winter, when indoor temperature higher water vapor to outdoor migration due to the blocking of hard foam polyurethane, impossible to condensation inside the wall. In the indoor humidity is low, and indoor wall wet insulation in good condition, and can avoid the water vapor condensation produced by moisture transfer inside the wall.

  ( 3) The polyurethane composite board tolerated the harshest local climate and its change. Both hot and cold climate, will not make the external thermal insulation system produces irreversible damage or deformation, external surface temperature of violent change, for example, in after a long time of exposure to a sudden rain shower, or after exposure to shade, similar to the temperature difference, the external wall surface will not cause damage. Thus to avoid the surface temperature changes resulted from the surface deformation of surface cracks.
