Is it true that brick houses tend to get colder in the winter than houses made of other materials?

It depends on how thick the walls are.  For an average 2 story brick home, if you’re worried about heating costs, you’ll probably want to invest in an extra insulation layer and double-glazed windows.  It would also probably help to let in more natural light.

What is an insulation layer, exactly?

When a building is constructed, the building blocks of the home are supported by a system of studs and joists.  Wooden framing systems are generally a good insulator, so they reduce the amount of heat lost from the building through the walls.  Double-glazing is like regular glass, except it’s laminated with an extra layer of glass to further reduce heat transfer.

And how do I install an extra layer of insulation on a home that's already built?

If you have the knowledge, tools, and time to do it, I think you could purchase a piece of foam insulation material, and then glue it to the wall.  If you're not comfortable doing this by yourself, I suggest hiring a contractor to do it.  The foam itself will probably cost a few hundred dollars, but hiring a contractor might cost a few hundred dollars more.  I think it would be really worth it in the long run though, since it would help to save you a lot of money over the course of your ownership of the home.

This is usually done during renovations.  If you’re planning a renovation, you can take some extra time to make sure you get the design right, and it’ll save money on heating in the long run.
