Abstract: A method of fastening a sheet of material to a support by first positioning the sheet material adjacent the support, cutting an elongated slot in the sheet material while embedding a portion of the sheet material in the support, securing a fastener to the support by moving a first fastener portion into frictional engagement with the support, positioning a second portion of the fastener to extend through the slot and providing a fastening portion to the fastener is disclosed. The slot is larger than the portion of the fastening means positioned therein so as to permit relative movement between the sheet material and the fastening means. This capability for relative movement between the sheet material and the support accommodates for thermal expansion and contraction of the sheet material thereby preventing binding and buckling of sheet material while retaining its alignment on the support.
