What components does VR refer to in a fully contained vinyl window?

In the context of fully contained vinyl windows, VR refers to a combination of essential components that contribute to the window's functionality and structural integrity. This includes interior stops, which help hold the window in place and provide a finished look on the inside; the interior/exterior sash, which are the movable frames that hold the glass and allow for operation; the exterior sill, which directs water away from the window; and the parting bead, which separates the different parts of the window sash and aids in ensuring a tight seal.

Understanding these components is crucial for lead inspectors and risk assessors, as they need to be aware of all elements of the window structure for thorough inspections. Each component plays a role in preventing issues such as water intrusion and air leaks, which can impact both the building envelope and indoor air quality. Identifying and understanding the full array of components in a vinyl window ensures that inspectors can provide accurate assessments and recommendations concerning potential lead hazards and overall window performance.
