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.
Claims7
A method for forming a sill pan, said method comprising:
- measuring a width and length of an opening sill to be sealed;
- cutting a rectangular piece of flexible sill pan material based on the measured opening sill, said sill pan material having a first surface, a second surface opposite to the first surface, an inner edge, an outer edge, and a pair of side edges, where the inner edge and the outer edge are parallel to each other and perpendicular to the side edges of the flexible sill pan material;
- creating a set of fold lines in said rectangular piece of flexible sill pan material to define a back dam along the inner edge, a downward flap along the outer edge, and a seat between said back dam and said downward flap of the sill pan;
- placing said seat on the sill;
- vertically supporting said back dam with a metal angle;
- and
- placing a toe bead of sealant at a fold line between said seat and said back dam
- wherein creating said set of fold lines comprises:
- creating a first fold line on said first surface that defines a height of said back dam at a first distance measured from the inner edge;
- creating a set of two second fold lines on said first surf ace that are perpendicular to said first fold line and are parallel to said side edges at a second distance measured from both of said side edges;
- and
- creating a third fold line on said first surface parallel to said first fold line at a third distance as measured from the outer edge that defines a width of said seat of said sill pan for seating a window frame, and said downward flap.

A method for forming a sill pan, said method comprising:
- measuring a width and length of an opening sill to be sealed;
- cutting a rectangular piece of flexible sill pan material based on the measured opening sill, said sill pan material having a first surface, a second surface opposite to the first surface, an inner edge, an outer edge, and a pair of side edges, where the inner edge and the outer edge are parallel to each other and perpendicular to the side edges of the flexible sill pan material, and where the second surface of said flexible sill pan material is waffled or dimpled;
- creating a set of fold lines in said rectangular piece of flexible sill pan material to define the sill pan, wherein creating said set of fold lines comprises creating a first fold line on said first surface that defines a height of a back dam at a first distance measured from the inner edge, creating a set of two second fold lines on said first surface that are perpendicular to said first fold line and are parallel to said side edges at a second distance measured from both of said side edges, and creating a third fold line on said first surface parallel to said first fold line at a third distance as measured from the outer edge that defines a width of a seat of said sill pan for seating a window frame, and a downward flap;
- cutting said set of two second fold lines that extend from the outer edge until the third fold line;
- and
- cutting said first fold line from opposing sides from said side edges until said second fold lines to form opposing ends.
