Considering that most houses have large windows (such as balconies) and high-rise buildings, the wall thickness of the profile should be greater than 2.5 mm. The inner cavity is a three-chamber structure with a closed drainage cavity and Isolation cavity, reinforcement cavity, in order to ensure that the window does not deform for decades. In addition, such profiles are less prone to discoloration and are less prone to aging.
