Signature Exteriors couldn’t do such a great job without all kinds of trustworthy help, like our vendors, and we’d like to give a shout out to them over the next few weeks in this Vendor Spotlight series. Part 3/3.

Alside Supply offers quality products for our exterior siding, window and door needs. They were founded 70 years ago and now have more than 3,000 employees across seven manufacturing facilities and distribute their products in 100 supply centers.

In 1947, founder Jerome J. Kaufman invented the first residential baked enamel aluminum siding after realizing that paint fuses with aluminum airplanes, and then in 1980 his research team developed vinyl replacement windows to adapt to the changing needs of the market.

In 1996 Alside developed Charter Oak™ Premium Vinyl Siding, which quickly got the moniker "the siding that changed the industry" and in that same year they produced their 5 millionth window. A few years ago they opened their 100th supply center, and today Alside is a leading manufacturer of vinyl siding, vinyl windows and patio doors, and fencing and railing products for both commercial and residential buildings.

Their website also includes an impressive FAQ page for all your homeowner questions.
