Innovative welding technology produces a straight, clean weld line while eliminating secondary cleaning and finishing processes.

SUGARCREEK, Ohio, July 1, 2019 ­ ProVia introduces its new FineLine™ Technology, which produces a straight, clean weld line on the corners of Endure™ Vinyl Patio Doors and achieves a “picture frame quality” look on the sashes. This unique process provides an enhanced fit and finish, and professional-class look, to patio doors. Following several years of development, ProVia is the first building products manufacturer to bring this new welding technology to the U.S. market. Doors produced with FineLine technology meet or exceed all industry requirements for strength and durability (AAMA / WDMA / CSA101 / I.S.2 / A440-11 Section 9.3.6.2 Thermoplastic corner weld testing).

Neat, Seamless Look

Across the U.S., most manufacturers use a traditional welding process to join vinyl patio door corners. This process creates a wide joint that must be cleaned and touched up. ProVia’s new FineLine Technology enhances the aesthetics of the finished corner without these secondary processes, resulting in a neat, seamless look. This delivers the highest standard of patio door craftsmanship and quality to the U.S. market.
