The ENVIROGUARD™ Difference

Impervious to rot and insects, ENVIROGUARD cellular PVC is our standard exterior on all of our specialty millwork. Our ENVIROGUARD Window Series of double-hungs, casements and radius millwork feature windows that are not only pleasing to the eye but also durable.

Cellular PVC Windows

ENVIROGUARD pioneered the use of cellular PVC for double-hung and casement windows. Cellular PVC is the no-rot, high energy savings alternative to wood, vinyl and other window and millwork materials. Today this technological breakthrough has become an industry standard, and represents the majority of our customer orders. We’re home of the Enviroguard Window Series, using 100% Enviroguard for sash, sill and exterior parts of our standard-sized and custom-built windows for protection against the elements. Our Enviroguard product lines have all the natural characteristics of wood, including great appearance–without wood’s shortcomings. They won’t peel, splinter, decay, absorb moisture–and have enhanced screw-holding power.

Cellular PVC vs Vinyl Windows

Vinyl replacement windows are very common and made using components made of polyvinyl chloride or PVC. Polyvinyl chloride is a combination of different chemicals, plasticizers and pigments. Polyvinyl chloride is also used to make plumbing pipes, electrical pipes, and many other plastic items. Window components for vinyl replacement windows are extruded and contain hollow chambers. The hollow chambers make for a lighter product and easier for welding the components together.

Cellular PVC windows are also made from polyvinyl chloride. However, thru a different type of manufacturing process the components are solid. Cellular PVC is unlike extruded hollow vinyl as it features a foam or cell-structure inside. It can be nailed, sawn and fabricated like wood. The window components (brickmould, sill, jamb, and sash rails) used to manufacture these windows look exactly like wood windows. Cellular PVC windows are solid and stronger than extruded vinyl windows which are thinner and can lead to warping.

Other Differences:

Architectural Style – vinyl replacement windows do not look like wood where Cellular PVC windows have the same architectural moldings as traditional wood windows.

pre-finish optionFinishing Options– vinyl replacement windows come in 2 interior colors, white and almond or tan. They are not manufactured to be painted. Cellular PVC windows can be painted to match your interior trim.

Maintenance – vinyl windows will never have to be painted. However, your color choices are limited and the color you choose will be your only future option. Once painted, cellular PVC windows require minimal maintenance and can be re-painted if you change your color scheme.

Glass Space – One major factor to consider is loss of glass space. When replacing wood windows with a vinyl replacement window, there will be a significant loss of glass space. A vinyl window has its own frame and inserts into the existing wood frame of the wood window after the window sashes are removed. So imagine removing the glass from your window, and installing a new enclosed window in a frame where this glass area was. This will result in a significant loss of glass space which will result in a loss of natural light.

When replacing your wood windows, ENVIROGUARD cellular PVC windows are your best option and will give you the highest return on your investment.
