Abstract
A sill for a window or door has a frame and a panel with a sill frame section defining at least one hollow chamber. A fastener extends through a wall of a hollow chamber and is secured to an adjacent structural member. A plastic element is secured to an interior surface of the sill frame section. The plastic element is disposed between the head of the fastener and a first opening through which the fastener passes to resist passage of water, air and sound through the first opening and into the window and doors. A plastic element is preferably coextruded with the sill frame section. A related method is a similar jamb frame section and a head frame section.
