Casement windows swing outward on hinges and crank shut to compress the weatherstripping on all four sides. That tight seal is why they rank among the most energy-efficient window styles available. But when the crank mechanism wears down or the frame shifts out of square, that efficiency disappears and the window becomes a source of frustration.
The team at Renewal by Andersen offers replacement casement windows built with Fibrex® material, designed to maintain proper alignment and smooth operation over the long term.
Casement windows operate on a hinge system. Turn the crank and the sash swings outward, opening the full height of the window for ventilation. Close it and the sash pulls tight against the frame, compressing the weatherstripping on all sides.
This design creates one of the tightest seals of any operable window style. Unlike sliders or double-hung windows, there is no track for the sash to slide along and no meeting rail in the middle of the glass.
However, old crank windows tend to fail in predictable ways. The gears inside the crank mechanism wear down and start slipping. The hinges loosen and the sash no longer sits square in the frame. The weatherstripping compresses permanently and stops doing its job.
Once alignment goes, sealing goes with it. You end up forcing the window shut or leaving it slightly open because fully closing it takes more effort than it should.
Renewal by Andersen casement windows address these issues with hardware built for long-term use. The folding crank handle operates smoothly and stays out of the way when you are not using it. Fibrex® material frames do not warp or shift, so the sash and frame stay aligned through temperature swings and seasonal changes.
Every casement window replacement from Renewal by Andersen is built to your measurements.
You can choose from 48 color combinations, including dual-color options that let you match your interior and exterior separately. Pick from 11 hardware finishes and a range of grille patterns to suit your home’s style. The narrow profile of Fibrex® material frames means more glass and less frame.
