The Alpha Plus Wall System



The Alpha Plus 3 1/2" white powder coated (AAMA spec's) aluminum wall system is ideal for 3-4 season use. This particular product was originally released back in the 60's and with years of refinements, remains an industry standard.


All structural member framing is painted aluminum 6063-T6 hardened alloy.


Windows are all made with our exclusive virgin vinyl compound and are optimized for longevity, made and built in Ontario, California in the USA! Vinyl will not crack, peel or corrode like wood or aluminum frame material can. The vinyl windows come in either a fixed or dual sliding format with a choice of glazing (clear or Low E).


All sliding windows come fixed exterior screens.

Ideal for 3 season usage and its tuff and durable design will last you years with just a little maintenance. It is very conventional while adding value to your home.
