Widely used in glass curtain wall is essential in building energy efficiency of
weather premise developed building energy consumption to 3 times 2 times, in building a well-off society process, energy conservation is a huge task. Progress Energy is a quiet residential building, reduce the use with
Foundation degree is also an urgent requirement for sustainable development, only to save resources, reduce energy consumption on the raised position in order to better promote a harmonious society.
65% of building energy conservation mainly borne by the building envelope system. Outer envelopes, as a major feature of modern buildings of glass curtain wall, of the last century 90's in our building has been widely used, but there are many topics, such as the improper choice of glass, lead glass, solar energy is through the summer, other materials wall several times; use of bad sealing adhesive junction, plastic construction joints in place, tape Mifengbuyan, structural deformation cracks, leading to cold, hot air infiltration to severe leakage; the use of profiles, thermal insulation materials , fill material is not fair, node approach is not accurate, is not among the components of an effective set gasket, making large indoor heat loss; together when the glass reflection light generated by light pollution, the structure does not become solid in the air "time bomb" and so on.
Selection influence the insulation effect
To take full account of the glass curtain wall insulation, heat insulation, sealing function, use the strength, rigidity sufficient material to prevent typhoons, earthquakes, gravity and other loads which produce glass walls thrown up by the deformation of the rift.
Maximize the use of coated glass, layer can impede their See solar radiation to the interior, such as the use of single coated glass should be used when online thermal spray method produced products (film is firm and good durability). Thickness of the glass related to structural safety, but also affect the amount of heat transmission, when using frame bearing walls, the chip thickness of not less than 6 mm glass, laminated glass thickness not less than 5 mm chip.
Insulation materials play an important role in energy conservation, but also strengthened the functions of fire prevention. Curtain wall construction should use rock wool, mineral wool, glass wool insulation materials such as insulation, thermal insulation function of its strengths is the good thermal conductivity is only 0. 044W / (m? K), the maximum temperature reached 650 degrees Celsius.
Glass and aluminum structural bond between the Deputy box required neutral silicone sealant, adhesive function of this structure is not arbitrary, and strong bonding. But the whole point supporting glass curtain wall and the use of coated glass curtain wall, should not be sealed by acidic silicone adhesive junction.
Weather construction sealant silicone sealant should be used. UV-resistant silicone sealant function is good, so durable, should not the aging of cracks, and with the structure of the silicone rubber, glass and other components have good compatibility and good bonding results.
Glass curtain wall surrounding the window opening slot, out the glass curtain wall box with the clearance profiles of suitable EPDM rubber, neoprene rubber or silicone rubber seals, in which silicone rubber (weather is good, permanent deformation small) the best quality.

you offer a lot of great information on the glass curtain wall and how it makes a building more energy efficient. I think it is the perfect way to let in a lot of light and make the inside a building much brighter. You give a lot of great reasons for adding one to a building. For anyone thinking of putting one into their home, I would suggest first looking at McGraw Hill Sweets Directory of construction products and manufacturers. They offer a lot of great information and the CAD details that you can download from their site are wonderful. They really make the planning stage go much more smoothly. Though I work for them, I honestly find that they offer really valuable information that makes my projects and my life much easier. you should take a look before your next project.
