Replacement Fiberglass Windows

Fiberglass windows are becoming increasingly popular with Seattle area builders, homeowners, and architects alike. These frames are strong, rigid, energy-efficient, and paintable. Fiberglass replacement windows are ideal for those homeowners seeking darker colors since the additional heat absorption from the darker colors does not distort the fiberglass frame. And because fiberglass is made primarily of glass, the fiberglass frame and the insulated glass unit expand and contract at very similar rates, thus putting less stress on the sealed insulated unit. In addition, fiberglass windows are one of the most eco-friendly windows around because they are made of an abundant resource (sand) and are environmentally-friendly to produce.

At Lake Washington Windows & Doors, we have chosen to offer Milgard Window's fiberglass line of window products, called the Ultra Series. Milgard is the largest fiberglass window manufacturer in the West with a proven track record for quality and service.
