Window Sills not only increase the curb appeal of your windows, but are also designed to prevent water damage around windows. Sills are designed with a slope running from back to front to force water away from your windows, preventing water from accumulating and leaking into your windows. The inorganic styrofoam, fiberglass mesh and modified cement they are manufactured from ensure the sills will never rot or permit mold growth because of water and moisture.
Because of this, our exterior sills make an ideal window sill replacement for those who have know the trouble of replacing a window sill. Exterior sills may be adhered to brick, stone, stucco, ICF and EIFS and siding.
Common misspellings: sil, cill, cil
