Exterior insulation exterior insulation, thermal insulation system is placed on the outside walls, so that the building construction methods to achieve thermal insulation. Since the outer insulation is railway sleepers from plastic waste placed outside the external walls of thermal insulation system, so that the temperature difference between the role of the main structure suffered significant decline, reducing the temperature deformation, the structure of the wall and can play a protective role in effectively blocking the cold (hot) bridge It is conducive to extend the life of the structure.

Therefore, from the stability of the structure, it is conducive to the outer insulation has obvious advantages, in the case of an optional external insulation should be preferred. However, since the outer insulation system is placed in the outer walls, various factors bear directly Pre Made Redwood Fence Panels Sri Lanka from nature, and therefore the external wall insulation system put forward higher requirements. To solar radiation and ambient temperature changes for its impact, as the insulation layer on the crack resistance of the protective layer is only 3mm ~ 20mm, and insulation material having a large thermal resistance, and therefore under the same conditions of heat, external insulation anti- The protective layer cracking temperature changes faster than the outer case without insulation body temperature changes faster pour 8 to 30 times.

Therefore, the protective layer cracking flexibility and weatherability crack resistance of external thermal insulation system plays a key role. 1, polystyrene board thin touch insufficient gray outer how to build l-shape patio bench Troms insulation structural design exist: Such external insulation usually pasted outside of France when fixed in the wall, and then the insulation board and reinforcing mesh Mama mortar surface mortar shop presses, at present, such practices are common, however, cracks also very much.
