The Application of Silicone Sealants in Curtain Wall

The exterior of a building is important for the structural integrity of the building. Curtain wall is one of the ways to protect your building from harsh outdoor elements, which is thin and lightweight usually made of aluminum and glass. These walls are not only able to carry their own weight, but also can transfer the load of wind and gravity to the structure of the building. The design of curtain wall have to make it air and water resistant in order to ensure that the interior of the building remains airtight. Thus, it’s vital to choose the right sealants to bond glass on aluminum plates or seal the gaps of curtain wall.

Bonding

Silicone sealant is a kind of high modulus and high elasticity silicone rubber. Compared with non-structural adhesive, silicone sealant is structural with high strength, so it can bear high capacity without damaged. Besides, silicone sealant has good adhesion properties on all surfaces and it can form a strong bond with most of materials without primer, so it can bond glass on aluminum plates together tightly. Meanwhile, silicone sealant is resistant in a wide range of temperature conditions from freezing winter to torrid summers, which can prevent curtain wall from aging and ensure it safe and durable.

Sealing the gaps of curtain wall

The sealant for filling the gaps of curtain wall needs to adapt to the changes of width caused by the external environment of the building, such as the heat expands and cold contracts of sheet, displacement of the main structure of the building and so on. While silicone sealant has high elasticity and can change with the width of gaps, which is the best choice for sealing the gaps of curtain wall.
