Gliding windows are ideal space-saving solutions, but there are problems that are inherent to their design. Fortunately, Renewal by Andersen® gliding windows overcome such problems, thanks to our high-quality builds and exclusive Fibrex® material. Let’s further investigate this topic.
Common Gliding Window Problems
Gliding windows rely on weatherstripping to prevent drafts and air leaks. Since sliding windows open from the side, the sashes do not exert downward force as on double hung windows nor do they press against the frame as casement windows do. Reducing the gap between the sash and the frame can help improve the seal between sash and frame, but thermal expansion needs to be taken into consideration. Even minimal expansion can make the difference between a good seal and a stuck gliding window.
Another feature that’s unique to gliding windows is the lack of mechanical operation. The sashes glide on tracks, whereas other styles are hinged (as on casement windows) or have counterweights (as on double hung windows). Since the combined weight of the sashes rests on the sill, bigger gliding windows are more likely to have issues with traction.
How Fibrex® Material Solves These Problems
Renewal by Andersen replacement window frames and sashes are made with our exclusive Fibrex material. Developed by our parent company Andersen® Corporation, Fibrex is a composite of wood fibers and polymer. It combines the strength and stability of wood, and the low-maintenance qualities of vinyl. As an extruded material, it lets us build custom profiles that fit our clients’ requirements.
Fibrex material has key qualities that make it the ideal material for gliding windows. One is its inherent insulation. This reduces the amount of needed insulation, which lets us build slimmer and lighter window frames without compromising structure. Plus, Fibrex material expands and contracts evenly. In addition to preventing warped frames, it also lets us reduce the gap between sash and frame, resulting in more reliable window performance regardless of temperature. In addition to this, we use weatherstripping that lasts longer than the ones on typical replacement windows.
