Thermwell W3636H Wood Threshold 3.5x36 in Low Rug Vinyl Insert

Product Description

The THERMWELL W3636H is a natural wood door threshold measuring 3.5 inches wide by 36 inches long, designed in a low rug profile with a vinyl insert. This threshold installs at interior or exterior doorways to bridge the gap between flooring surfaces and seal out drafts, dirt, and moisture at the door base. The low rug style profile accommodates transitions where carpet or low-pile rugs meet the threshold, keeping the transition smooth and flush. The vinyl insert provides a weather-resistant seal and can be replaced independently when worn, using replacement insert model RV37H. Flooring and door contractors as well as experienced DIYers perform this installation as part of routine door finishing or weatherization work.

This threshold is suited for residential doorway applications where a natural wood aesthetic is desired. It works at interior passage doors and at exterior doors where a low-profile wood unit is appropriate. The replaceable vinyl insert extends the service life of the threshold by allowing the seal component to be swapped out without replacing the full wood base. The 36-inch length fits standard single-door openings and can be cut to width on site as needed.

Installation Notes

Installation is typically performed by a finish carpenter, door installer, or experienced DIYer. Before installation, remove the door from its hinges if clearance is tight, and ensure the subfloor or existing threshold surface is clean and level. Secure the wood threshold to the floor with appropriate fasteners for the substrate; pre-drilling is recommended to prevent splitting the wood. Replace the vinyl insert using model RV37H when the seal shows wear, without removing the wood base.
