How to seal the joints of doors and windows?

Doors and windows are the most important components in ensuring not only structural stability, but also delivering on essential comfort and safety needs. They must be airtight, waterproof, energy-efficient and, when needed in specific environments, soundproof and protect against dust or insects. Doors and windows can be made of different materials such as aluminum alloy, wood or a combination of materials. Usually, aluminum doors and windows are the most common, and silicone sealants are increasingly applied in bonding the gaps between the aluminum alloy and glass and other materials.

Silicone sealants are formulated with different functional group structures in the organic silicon polymer main chain to be flexible, adherent and extremely durable over time, so that they can continue to deliver the performance level of their initial specifications for many years. So applying them can prevent effectively doors and windows from aging. In addition, silicone sealants have good adhesion properties on all surfaces, from plastics, stainless steel, glass, PVC to stone. Meanwhile, silicone sealants are waterproof, UV resistant and weatherproof, and they have resistance in a wide range of temperature conditions from freezing winter to torrid summers. Besides, silicone sealants have excellent elasticity to prevent breakage and they are safe without any toxic substances for end-users. For doors and windows that have to be exposed to the outdoors all the time, silicone sealants with above properties fully meet the requirements of sealing the gaps of doors and windows.
