Z-Plus Sill 

The Z-Plus sill is thermally broken with a full width substrate.  This cost-effective product is great for customers who mainly install 2/8 or 3/0 standard sills, without a lot of odd sized units.  The all composite substrate is impervious to water and will prevent the sill from rotting, warping and deteriorating over time.

The Z-Classic Sill

The modularity of the Z-Classic sill allows our customers to hold inventory down while offering a larger variety of door configurations.  The all composite substrate is impervious to water and will prevent the sill from rotting, warping and deteriorating over time.
