Air seal gaps in exterior timber sliding and bi-fold doors can be problematic, especially older type hardware systems that may be wearing. There can be a number of issues that cause air leaks, the most common being a gap between the end that should overlap the inside edge when shut. Warping of older hardwood over time can cause these gaps to open up and allow air to penetrate easily. A renewal or reinstatement of a foam type stick on seal will help, or if the gap is at the strike end it is also possible to plane straight the door edge so that a flat seal is obtained.

With Winter upon us and energy bills set to increase it is perhaps time look at the alternatives. Timba Windows manufacture doors made from kiln dried hardwood from Australian native plantation timbers ensuring superior air seal over the life of the joinery. Modern high quality hardware used also has better wear properties including top hung sliding mechanisms and brush type air seals on bifolds.
