Double Hung Vinyl Window

ENERGY STAR certified windows come in a variety of framing materials.
Fiberglass frames are strong, durable, low maintenance, and provide good insulation. Fiberglass frames can be either hollow or filled with foam insulation.
Vinyl frames are low maintenance and provide good thermal insulation. Sections may be hollow or filled with foam insulation. Wide vinyl sills may be reinforced with metal or wood.
Aluminum frames are durable, low maintenance, recyclable, and typically have at least 15% recycled content. Frame design typically includes thermal breaks to reduce conductive heat loss through the metal.
Wood frames are strong, provide good insulation, and are generally favored in historical neighborhoods. The exterior surfaces of many wood windows are clad (or covered) with aluminum or vinyl to reduce maintenance.
Combination frames use different materials separately throughout the frame and sash to provide optimal performance. For example, the exterior half of a frame could be vinyl while the interior half could be wood.
Composite frames are made of various materials that have been blended together through manufacturing processes to create durable, low maintenance, well-insulated windows.

Windows, doors and skylights protect you from the elements just like a winter coat. But like a winter coat, you should pick the windows, doors and skylights that make the most sense for your climate. While some windows, doors and skylights are better at keeping you warm, others excel at keeping you cool.

TESTIMONIAL
"G.S. Construction Exterior Experts was awesome to work with. From discovery to completion they were professional and courteous. They were by far the most knowledgeable about the James Hardy Product I chose and they were very conscious about the manufacturers specifications when it came to installing. The three crews that worked on my house, Demo and Install, Gutters, and Painting were all punctual and professional. Not only would I recommend GS to someone else I already did. Great Company - Great People."
