First day of spring weather, and suddenly, you don't care about the insulating qualities of insulating windows. You want fresh air.
If there were not another difference between Alcoe and other brands, our easy-open glass panels with the single-point locking device would still make your choice easy.
All you do is flick a lever or turn a knob, then slide the glass up or down. No fuss. No bother. No two-fingered nail-breaking jerk and lift.
And removing it for cleaning is just as easy. Glass panels are held in place by a flexible spring-loaded vinyl track. Just give the window a slight push into the left jamb, and pull the glass out. Even the sill lifts out for easy cleaning.
Alcoe's spring-loaded construction allows the glass panel to "float," maintaining its seal and free action under the worst circumstances -- even in wet weather, when the primary window is prone to swelling and binding, or if the frame gets out of square from foundation settling.
