Weather Bar

The lower bar of the window frame that forms the transition from glazing to sash is usually exposed to the elements. Rainwater can collect here and damage the wood of your windows. A so-called weather bar or drip bar protects this exposed area of the frame. It is a sloped element attached to the bottom of the sash that ensures water does not collect or enter the rebate but drains away immediately. The classic weather bar has been replaced by the so-called rain protection rail, which can be attached to the frame and is also retrofittable on existing windows. This is usually combined with a sash cover profile with rubber seal for the glazing rebate.
