Abstract
A spacer strip for use in a sealed window unit is manufactured from a pultruded fibreglass reinforced body providing a substantially closed hollow body with a slot along one side. The strip is manufactured by pultrusion using a die which is slightly more open than the finished product including a mandrel supported by a web wider than the eventual slot. Closing of the body into the eventual shape is obtained either by differential shrinkage using matting on the outer surface of the body or by squeezing the body between heated rollers. A sealed window unit incorporates the spacer strips between two panes of glass adjacent the edges thereof and incorporates a dessicant communicating with the space between the windows through the slot.
