introduction to steel doors
Versatile doors made of steel can blend into just about any architectural style and they can accommodate any number of
decorative windows. Their rigidity, longevity, air tightness and ease of maintenance make them a good choice. In
addition, these doors yield impressive insulation value at relatively low cost.
Steel doors are made of two sheets of steel between which polyurethane foam is pressure-injected. In terms of
insulation, standard 1 3/4 in. doors rate an R16 everywhere, except in glassed-in and etched areas. Large glassed-in
areas are very popular despite their poor energy efficiency. On the positive side, they don't let in outside air.
Steel doors are delivered in wood frames, which should be as deep as possible, consistent with the thickness of the wall
into which the door must fit. Standard frames are 4 9/16 in. deep except for Quebec where it is 7 1/4 in. Bear in mind
that manufacturers can make frames to suit every need.
Steel doors allow the use of magnetic weatherstripping, at the top and around the lock. That makes them unusually
airtight. Flexible weatherstripping can be used around the hinges while the bottom of the door typically has an
interlocking threshold.
There is a huge range of steel doors on the market, it is really up to you to do your research before deciding which
might be best for your situation. They can be used as additional security doors or as fire breaks. Please make sure
that your own safety is not jeapordised ... can you escape
