The HiMark 800 EnviroStar window is considered one of the best vinyl window replacement option on the market. It combines excellent performance ratings, a well-made vinyl extrusion, and high end features and components. All of which combine to make a very durable vinyl window that feels as solid in your hands and will provide consumers with excellent long term value and performance.

The 800 series window includes a slew excellent features, including a 3 1/4" depth mainframe, beveled colonial frame, true sloped sill, multi chambered mainframe, recessed vent and tilt latches, composite sill reinforcement, magnetic seals and triple weatherstripping. The 800 Series uses a heavier extrusion than the 500, making it feel a bit more substantial. This is going to help a bit in terms of the performance, which is excellent on both windows.

Homeowners can choose from some 8 exterior frame color option and 4 interior color color options, including several wood laminates. These faux wood grain finishes mimic the look of real wood, without the maintenance needs and lower energy efficiency that organic materials such as wood often deliver.
The HiMark 800 Window Series gets a 5 out of 5 star rating.
