Up until the 1950’s and into the 1960’s, residential back and side doors almost always were only 1 3/8″ thick doors, frequently with only ?” thick panels and annealed single-pane glass.
This was obviously before burglary and energy conservation were a common part of our culture’s residential construction lexicon.

We always add an extra hour or two of labor to deal with the issues related to fastening the jamb assembly & running the trim around the concrete. There’s usually lots of extra caulking work.
But problem solving is what door & window installation is all about. If you don’t learn to relish the challenges, you’re really in the wrong trade.
Loewen wood-clad doors and windows. A serious contender in the top-shelf door & window market.
Their entry level wood product is a FIR product. Fir is not an upgrade in the Loewen world.
