Entry doors
Fiberglass and steel entry doors at 3,960 feet and a 100-degree
afternoon
An entry door on a west or south elevation here is the hardest-worked component on the
house: a large, flat, often dark surface standing in full sun with conditioned air against
the other side, expected to stay flat and keep sealing while that gradient reverses every
night.
A steel door is a formed skin over a foam core on a wood or composite frame. It is the
stronger of the two at the lock, it costs less, and its coating is the entire defence: once
that is broken at an edge, a hinge screw or a kick plate, the substrate has no second line.
A dark colour on a sun-facing slab makes that harder, not easier.
A fiberglass door is a moulded skin over the same kind of core. It moves less under heat, it
carries a dark finish more comfortably, and it does not corrode at all, which matters where
the dust is alkaline and the ground around town is under irrigation for part of the year. It
costs more, and it fails differently when something hits it: it cracks rather than dishing.
We carry Codel and Jeld-Wen
entry door lines
and will price either construction.
Whichever slab you choose, the parts that decide whether the door still works in ten years
are the ones nobody itemises: the threshold and its adjustment, the sweep, the compression
weatherstrip in the jamb, and the finish on the hinges and lock. On a west elevation we would
rather spend there than on the slab, and those items are named on the scope.
