Sliding Patio Doors

Green Gables Windows & Doors are a proud partner of ProVia, as well as Associated Materials Inc. (AMI), and its subsidiary, Alside, Inc.

ProVia is nestled within the rolling hills of Sugarcreek, Ohio, the heart of the nation’s largest Amish population.  The company was started in a garage by Bill Mullet more than 40 years ago and has grown into a nationally known manufacturer of high-quality entry door systemsenergy-efficient, vinyl replacement windowssuper polymer vinyl siding,  artfully-crafted, manufactured stone, and lifetime-lasting metal roofing.  ProVia has built a reputation in the building products industry for quality, old-world craftsmanship and personal care for customers, which extends to every part of our culture.  The company has been through many changes to accommodate its growth, including expansions, acquisitions, and the implementation of state-of-the-art production equipment.  The current headquarters, constructed in 1984, underwent major renovation and expansions in 1993, 2001 and 2005 and 2012/2013.

ProVia remains privately owned by the Mullet family and continues to invest in its facilities, employees, customers and research & development. The company continues to manufacture outstanding replacement door, window, vinyl siding, manufactured stone and metal roofing products with a dedicated growing team that distributes products throughout most of the United States.

Alside is headquartered in Cuyahoga Falls, OH, and dates back to 1946 — getting its start under founder, Jerome J. Kaufman.  Kaufman had just invented the first residential baked enamel aluminum siding.  Alside then became a pioneer in the vinyl window industry, designing and building it’s first vinyl replacement window in 1980.  For over 70 years, Alside has continued to provide leadership and excellence within the exterior building products industry.  I’ve interacted and worked with Alside for nearly a decade now, and I’ve always been impressed with their operation — and certainly a fan of their fine quality windows.

Both ProVia and Alside manufacture several different vinyl sliding patio door models (think: “good, better, and best”).  All vinyl sliding doors offered by Green Gables are made with 100% first-generation virgin vinyl — this means no re-manufactured resins, and no: fading, discoloration, chipping, cracking, or peeling (on their white, beige, and classic clay windows).  All doors feature a variety of high-efficiency, energy efficient glass packages.  All ProVia & Alside doors come with a limited lifetime warranty — insuring peace of mind for you going forward.
