【正文】 es of windows. It is extremely hard and thus highly scratch, dent and impactresistant, and its strength is unaffected by time or temperature. Compatible thermal expansion. Because fiberglass frames are essentially glass fibers and resin, the frames expand and contract very little and at approximately the same rate as glass itself. If there is any expansion and contraction, the ponents expand and contract as a unit, unlike most window and door frames which have an interface of different materials: glass on wood, glass on aluminum or glass on vinyl. Aluminum is said to expand and contract three times as much as fiberglass and vinyl over seven times more. The minimal expansion and contraction of fiberglass puts less stress on the seals and frametoseal connection is maintained during temperature changes throughout the day and the seasons, thereby reducing the potential for air infiltration, a major cause of a building39。 high condensation resistance helps keep humidity within a suitable range and limits the growth of mold and mildew.

While early vinylwindows had problems with thermal expansion (the vinyl sash would expand or contract at a different rate from the glass and cause leaks) and stability in very hot environments, modern vinyl windows are much more durable and dimensionally stable. Vinyl window frames with heatwelded joints are stiffer than mechanically joined vinyl frames and thus provide better resistance to temperature stresses. Interior webs also strengthen the frame and improve its thermal performance Vinyl windows are made primarily from polyvinyl chloride (PVC) which is virtually maintenancefree. Vinyl frames can39。 Available in a wide range of styles and shapes Narrow sight lines maximize view s Administration Building underwent a general upgrade and restoration, phase 1 included replacement of 200 windows. Pultruded fiberglass doublehung retrofit frames were installed. Because the requirements exceeded the usual height limitation for this line of windows, units were custom designed to match the historic references. The brick and granite fascia had to be equipped with dividers across the center of the middle and top story windows. On the interior, the clear vertical ir grain was easily matched with the existing finish. Fiberglass windows, which were also selected because of high energy efficiency and low environmental impact, replaced singlepane.
