Weather Seals & Draught Excluders For Windows & Doors


Originally sash windows never had any weather seals. The design of the window offered basic draught control that was satisfactory for the times. Indeed some draught was desirable to ensure a good draw for solid fuel fires. With the advent of modern materials and the decline in use of solid fuels, weather stripping has become an essential part of any modern window.

There are several plastic parting beads available and some incorporate a quality weatherpile. The big disadvantage with these beads is they can not be painted. Even when used in a white window the plastic ages differently than surrounding paint work, detracting from the overall aesthetics. At Sash Window Specialist we only use traditional timber parting beads.
