When buying new vinyl windows or a patio door, your expectation should be a product devoid of imperfections that can make the window or patio door look flawed. ProVia's new FineLine™ welding technology is the first process in the building products industry that creates clean weld lines for the interior and exterior frame and sash corners of laminated windows and patio doors—eliminating the need for secondary operations that fix weld lines.

Jarret Mathie, ProVia manufacturing engineering manager, and Angela Duck, social media specialist, discuss and demonstrate the benefits. FineLine technology is now the standard for the company's Endure® woodgrain laminated windows and patio doors and is available as an upgrade for white, beige and sandstone Endure windows and patio doors.
