CertainTeed Undersill Trim

CertainTeed’s Vinyl Undersill Trim is designed to secure trimmed siding panels under eaves and windows, while the utility trim replaces the nailing hem to help secure the panel to the wall. It is low maintenance, but still provides a high level finish to a home and it comes equipped with other helpful features, including a Class 1(A) fire rating, PermaColor Fade Protection and a Limited Lifetime Warranty. The undersill trim also comes in a variety of different color options.
