Analysis And Prevention Of Building Exterior Wall Insulation Water

Analysis and Prevention of Building Exterior Wall Insulation Water
As the building insulation wall insulation materials 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 insulation 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.
Joda main products cover 5 series which including aerogel insulation blanket, aerogel insulation board, aerogel particles & powders,aerogel glass and aerogel coating. Those products used in thermal insulated steam pipeline, directly buried steel jacket steam pipel, furnace body insulation, building insulation, mine-used lifesaving cabin/mine rescue capsule, railway vehicles, mlitary doman and other fields. Our products is exported to southeast Asia, South America, Europe, Africa, Middle East and other regions.
Our company has its own professional R & D team, dedicated to the development and production of SiO2 aerogels Thermal insulation materials, the use of advanced supercritical CO2 fluid drying equipment to do aerogel drying, to ensure the quality of the product. I have a production line has been put into operation, can achieve 3000 cubic meters / year capacity. Is currently planning two, three of the construction, and ultimately can achieve an annual output of 20,000 cubic meters of production capacity.
