Compressible spacing and sealing apparatus for siding panel joints

Claim 1

A flashing apparatus for spacing and sealing adjacent panels comprising: a central portion lying substantially in one plane and having a front edge and a rear edge; first upwardly extending flange connected to and extending from the rear edge of said central portion; a secondly downwardly extending flange connected to and extending from the front edge of said central portion; and an improvement comprising: a plurality of projection means extending from said plane for resiliently spacing said siding panels apart, adjacent ones of said projection means alternatively extending upwardly and downwardly near the longitudinal center of the central portion and substantially evenly spaced apart along a substantial length of said central portion, each of said projection means being rigidly connected to said central portion about the entire periphery thereof along said plane whereby said central portion between adjacent projection means can flex to allow for expansion or contraction of the panels disposed on opposing sides thereof; a first wooden panel disposed underneath said central portion and having a top planar surface therein in abutment with said downwardly extending projection means and having said second downwardly extending flange extending parallel to a front top edge thereof; a second wooden panel disposed above said central portion and having a bottom planar surface in abutment with said upwardly extending projection means and also having a lower rear portion thereof in abutment with said first upwardly extending flange; and a wooden stud in abutment with said first upwardly extending flange and with the top rear portion of said first wooden panel whereby expansion of said first and second panels due to varying moisture content and temperature changes is permitted without causing buckling of said first and second wooden panels.
