When you reach a sill for an opening,form the left side of the opening using <br /> the End Block and half block(both have a smooth end-face),place the temporary buck in the <br /> opening and resume stacking on the opposite side of the buck. <br /> I� >a t , <br /> r <br /> , <br /> ,41"1 <br /> aY � <br /> 4; <br /> t -IM Este' <br /> The illustration shows window openings that follow the 12"wide x 8"high module rule: 4' wide <br /> x 48"high on the left and 3' wide x 56"high on the right. The door opening will need to be <br /> treated differently since most standard doors' rough opening is not a 12"increment in width. <br /> Layout the door on a I' increment from the corner as shown. This eliminates the need to cut any <br /> block on the left side. Then modify the right side Endblocks and half blocks as explained earlier. <br /> IMPORTANT: MODIFY THE SIDE ADJACENT TO THE OPENING. This preserves the <br /> proper alignment of vertical cells for optimum structural strength. <br /> 4 13'from comer c <br /> �II <br /> Alternative method for doors: Instead of screwing on the ends of the wallforms to make the <br /> shorter custom units you may cut the wallforms to the appropriate length then screw on a 12" <br /> wide piece of pressure treated plywood. The plywood remains in place after filling the <br /> wallforms with concrete and becomes the attachment point for the door frame. <br /> ShelterWorks General Application and Technical Information(GATT)version 2.5 <br />
