tempered glass but might also be annealed glass a continuous mound of sealing material 12 is placed about the periphery of one surface of transparent pane 11 the sealing material preferably is buterate from protective treatment inc of dayton ohio plastic spacers such as 13 are placed into the sealing material at intervals about the periphery of pane 11 spacers 13 include a portion 16 which is inserted into the sealing material fig2 and a head portion 14 generally circular in shape and having a diameter determinitive of the spacing of the double paned window to be constructed the continuous mound of sealing material is originally applied to pane 11 in a height or thickness greater than the diameter of head portion 14 of spacers 13 a second pane of transparent material 17 also preferably tempered glass is aligned with pane 11 and forced into sealing engagement with sealing material 12 panes 11 and 17 are forced together until they are maintained in a spaced apart relationship by spacers 13 since the mound of sealing material 12 was thicker than the diameter of head portion 14 of spacers 13 the sealing material 12 is continuously engaged by the outer edge of the facing surfaces of panes 11 and 17 thereby enclosing a sealed area in fig3 panes 11 and 17 are illustrated forming the above described enclosed area however two portions of upper pane 17 have been shown cut away in order to more clearly illustrate the procedure for providing a dry atmosphere to the area enclosed between the panes in accordance with the present invention there.
