Abstract

A sill support for protecting the sill of a window or door in new or retrofit construction which minimizes the need for on-site fabrication and comprises left and right end dam sections that engage a center connecting member of variable length depending upon the width of the door or window opening being treated.

Claims

1. A sill support system comprising:

A) left and right end dam sections that are mirror images of each other and each comprise;

1) a base having an upper and a lower surface, a front and a rear longitudinal edge and a left and a right extremity,

2) an upright end flange extending upward at a generally right angle from the base at one of the left or right hand extremities of each of the left and right hand end dams,

3) longitudinal grooves in the base upper surface; and

B) a center connecting member comprising;

1) a base having an upper and a lower surface and a front and a rear longitudinal edge;

2) longitudinal ridges in the center connecting member base lower surface that engage the longitudinal grooves in the left and right end dam base upper surfaces upon overlap of the center connecting member base with the left and right end dam bases;

3) upstanding and downstanding flanges that extend along the length of the rear longitudinal edge of the center connecting member.

2. The sill support system of claim 1 wherein the left and right end dam upper surfaces and the center connecting member base upper surfaces are slanted about 20 degrees upward from their front longitudinal edges.

3. The sill support of claim 1 further including a downstanding flange extending at an angle of less than about 90 degrees from the front longitudinal edge of the center connecting member base.

4. The sill support system of claim 3 further including a drip edge extending downward from the downstanding flange at an angle of about 45 degrees.
