Why Choose the Aspen EcoPro?


What sets the Aspen EcoPro Composite Window apart from others on the market? The key lies in its construction using advanced polymeric composite (APC) material, allowing for solid sashes and frames that eliminate the need for additional insulation. These windows feature rigid, extruded interlocks at the meeting rail, ensuring a tighter seal to minimize drafts. Additionally, they come with beautifully designed ergonomic hardware in modern finishes and multiple glass options to satisfy any homeowner’s needs.

The Aspen EcoPro Composite Window utilizes a butt-joint weld, combining traditional joinery aesthetics with the strength of advanced fusion welding. This method not only enhances the product’s durability but also provides the elegant look of a true wood window. Offering some of the best thermal performance benefits in the industry, these windows incorporate a variety of principal features which includes bulb gaskets on the top and bottom sashes and meeting rail, a dual dam leg sill and sash interlock, and V-Fin gaskets on the sides, ensuring a tight and efficient seal.

Interior Vinyl Window Colors

Aspen EcoPro Max offers four beautiful internal window laminates in addition to our standard White to give your home a distinct look. If you want to keep your home bright choose the white and almond interior window colors to increase the appeal of the natural lighting. If you want to go for a more traditional look choose the wood grain window laminates.

Exterior Vinyl Window Colors :

To give your home a unique appearance and increase curb appeal, The Aspen EcoPro provides six optional exterior stock colors and custom exterior colors from a virtually unlimited selection of paints. Therefore, if you are looking to color match or choose a more unique color you can choose from an almost infinite variety of paints from the Sherwin Williams collection to create custom exterior colors. Theses options can also be used as exterior window trim paint colors as well. Our custom window paints are environmentally safe and durable, giving your window a vibrant and long-lasting color finish. Printed colors may not match the product’s actual color so setup a appointment to view actual color samples.

Custom Window Grid Options

GBG grilles are made of aluminum bars that are sealed in the insulating area between the two glass panes. This makes cleaning your windows significantly more simple since both the inside and exterior glass surfaces are unaffected.

A permanent interior and exterior grid with spacer will give the room a genuinely genuine appearance. To match the style of your home, interior grids are also available in wood laminates or Euro-White. External grids are offered in Euro-White or exterior-compatible colors. Of course windows grids are optional if you prefer windows without grids.
