Types of UPVC Profiles
There are 2 family types of uPVC profiles. They are the American and European. In each family there are 2 types of profiles. They are the main and supportive. The main are ones such as the frame, sash, and mullion profiles, and supportive, like the glass beds, connectors, etc.
There are major differences between the 2 big uPVC profile families. American uPVC profiles are thinner and do not have steel reinforcement. They use American style hardware like the outswing crack or double hung system. European uPVC profiles have a completely different design. The they are inswing, have steel reinforced frame and sash, have a multi point locking system, and a tilt turn operation style. Their supportive profiles are also bigger than the US ones. Both window ecosystems have advantages and weaknesses. So, it is important to choose the right one for your build. Different manufactures like to specialize in different ecosystems.
