A beautiful knotty alder wood door is a great choice for your home entry. JHK offers a wide range of exterior door styles with a variety of glass designs. As always, we offer the most competitive prices through a "direct from manufacturer" distribution model. We also provide these doors with factory-added pre-suspension and pre-decoration, further reducing construction time and project costs. Furthermore, we transport the pre-hung doors (individual units) directly to the home or work site, thereby avoiding site reassembly. All of our Knotty Alder doors enjoy industry-leading warranties.
With a few exceptions, alders are deciduous, and the leaves are alternate, simple, and serrated. The flowers are catkins with elongate male catkins on the same plant as shorter female catkins, often before leaves appear; they are mainly wind-pollinated, but also visited by bees to a small extent. These trees differ from the birches (Betula, another genus in the family) in that the female catkins are woody and do not disintegrate at maturity, opening to release the seeds in a similar manner to many conifer cones.
