Description

This paper examines the role that draught seals can play in the opening joints of doors and opening windows and suggests levels of performance which should be achieved. Draught seals need to be extremely easily compressible to avoid excessive closing forces. Many of the systems available were found to be too stiff to cope with varying sized gap widths around a warped door. Of the seals available for retrofit application only one generic type was sufficiently tolerant of varying gap width. Most of the materials were found to be adequately airtight.
