PULTRUDED REINFORCED SPACER FOR SEALED WINDOW UNITS ABSTRACT OF THE DISCLOSURE A spacer strip for use in a sealed window unit is manufactured from a pultruded glass fibre reinforc- ed 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 dif- ferential 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.
