Fixed Inswing Sills 
The narrow threshold cap has improved positioning with the weatherstrip as it places run-off water in front of the dam and away from the cap.  
Full/Block Substrates
Endura's All-Composite Substrates won't absorb water like wood and prevents the sill from ever rotting or warping.  Our wide substrates provide exceptional support to the sill base and an increased staple/nail area.
Z-Plus sills are an efficient alternative to the Z-Classic line (which utilize a full substrate), while still providing outstanding protection from the elements.  Z-Plus sills are available in block or full length substrates and narrow or full side substrates.
