Door Thresholds for Exterior doors
High-performance thresholds
With ImperiSealTM Technology
Door Threshold Products
Designed for Performance, Designed for you
Our high-performance door thresholds for exterior doors are engineered to virtually eliminate air and water infiltration, meet code and ADA requirements, resist weathering, and enhance efficiency with pre-assembled components, all while offering built-in flexibility. Whether you need a durable aluminum threshold or the classic look of a hardwood door threshold strip, we have the perfect solution.
Quanex’s ImperiSeal™ technology is your best defense against the elements. With a continuous filament that positively seals the adjusting rail to the deck of the sill, a unitary exposure surface is created that stops water at the threshold and eliminates the need for sill pans.
