Abstract: A joiner clip for securing panels to a substrate is provided that includes a sheet of material that has a first portion, a second portion, a first face, and a second face. On the first face, a first anchoring cleat is located in the first portion and a second anchoring cleat is located in the second portion. A spaced guide is positioned between the first portion and the second portion of the sheet on the first face. A mounting hole is formed through the sheet and is positioned colinear with the spacer guide. A fastener from the second face secures the joiner clip and panels to a vertical stud substrate. A construction unit including the joiner clip for securing panels of material to a vertical stud substrate is also provided. A butt joint is readily formed between two secured panels.

Abstract: A method for forming a sill pan is provided that includes the measurement of a width and length of an opening sill to be sealed. A piece of flexible sill pan material is cut based on the measured opening sill. Fold lines and cuts are created in the piece to form the sill pan. The resulting sill pan is readily formed to have at least one attribute of self-adherence, draining without shims, nail hole self-sealing, and provision of dams without resort to frame cutting.
