Enviro-Star 800

The elegant, beveled profile of the 800 series will enhance
the beauty of your home’s exterior.

Enviro-Star 800 Series offers traditional look and feel of wood with the performance and ease of maintenance you can only get with vinyl windows.
The smallest details, such as the rounded beveled edges of the glazing bead, are a nod to the classic.

Enviro-Star 800 was designed to authentically represent a traditional wood window.

The classically refined line of the 800 series brings to mind a traditional wood window without most of the maintenance responsibilities.

A streamlined design, packed with a variety of features makes this window a sophisticated choice. The 800 series offers hardware options reminiscent of classic wood windows. It is the only vinyl window we manufacture without an integrated lift rail. The double hung features a handle style based on traditional wood windows. Recessed vent and tilt latches give the window a streamlined appearance as well as making clean-up a breeze. The reveal of the top sash at the meeting rails is a distinguishing mark of the 800 series, drawing inspiration from classic wood windows.
