The vinyl double hung windows have different options, including the one with fusion welded mainframe and sashes. The sill of the vinyl window maintains the temperature of the room and prevents any weather disruptions inside the home. When the sash is closed down, the weather stripping bulb seal comes in between. The seal helps to prevent the chilling cold winds to enter in home.
