Analysis And Prevention Of Building Exterior Wall Insulation Water

Analysis and Prevention of Building Exterior Wall Insulation Water

As the building insulation materials wall insulation layer is not allowed to enter the water, if the insulation layer of water, it is not insulation, and more serious may cause leakage. Outside the wall insulation layer of the main parts: The outer wall has cracks or holes; the window at the mouth; highlight the external walls of the eaves, decorative lines or other components and the wall intersect the root: wall exposed glass mesh.

1, resulting in building wall insulation water causes:

(1) not in accordance with the rules of design or construction, resulting in cracks in the external walls, holes and other water parts.

(2) highlight the wall decoration line, eaves and other surface down slope, water; doors and windows under the mouth of the slope or slope is small, the surface flatness is poor, there is water; bottom slope to the inside side, no dripping water eaves or eagle Mouth, water along the bottom and the wall joints into the insulation layer.

(3) outside the doors and windows of the benzene plate above the height of the doors and windows, the water hole into the insulation layer directly into the insulation layer.

(4) Roof and external heat insulation material node handling unreasonable, leakage to the insulation layer.

2, building exterior wall insulation measures:

(1) doors and windows under the mouth, highlight the walls of the eaves, decorative lines and other components on the surface drainage slope i ≥ 3%, under the bottom and doors and windows should be set up olecranon or drip line eaves, to prevent water into the insulation layer.

(2) to strengthen the design and construction management, to prevent external wall insulation cracks.
