Learn the processes and meet the people behind milgard fiberglass windows and door. Fiberglass windows are ideal for any style and climate. The growth in the use of pultruded fiberglass window components will be driven in part by new technology and an increasing demand in the market for windows that are capable of better performance. Fiberglass windows are manufactured using a pultrusion process where glass fibers are coated with resin and pulled through a hot die the shape of the frame or sash profile.

Ultra series windows have fiberglass frames inside and out and are available in four exterior colors. How we do it omniglass sct uses pultrusion a process for the continuous manufacturing of composite materials coupled with our proprietary entry feed technology. Pultrusion is a continuous molding process using fiber reinforcement in polyester or thermosetting resin matrices. We design and manufacture the highest quality fiberglass components for doors and windows on spec and on time.

Heat is used on the thermoset resins in the fiberglass pultrusion process to cause an irreversible chemical reaction which permanently sets the shape of the fiberglass window frames. Fiberglass material tolerates heat and cold while it resists swelling rotting and warping making fiberglass windows durable and low maintenance with little upkeep required. The heat cures the fiberglass resin to form a permanent shape that remains unaltered by any environmental condition. Pultruded fiberglass windows offer greater dimensional stability impact resistance strength and color fastness than the vinyl and wood windows that still dominate the residential construction market.
