Three sizes of brick are most common in the Ottawa region: Ontario, CSR, and, less so, the Quebec size.
Shown is the Ontario size.
The Quebec size: 3 3/4" x 2 1/4" x 8"
The CSR size: 3 1/2 x 2 3/4 x 9 1/16
Bricks may be made from clay, shale, soft slate, calcium silicate, concrete, or shaped from quarried stone.
Clay is the most common material, with modern clay bricks formed in one of three processes - soft mud, dry press, or extruded.
Clay bricks typically take on a reddish hue when baking. The red hue darkens when they are heated over a longer period of time. Red bricks can have warmer or darker tones mixed in with the overall red coloring.
Different minerals and chemicals found in the raw materials for the bricks can create other colors besides red, however. Pink bricks are created from clay high in iron. When the clay is fired, the reaction from the heat with the iron gives the hardened clay a pink tint that is too light to be called red. Bricks with a light, whitish or yellow tint occur when the clay has a high lime content instead of being high in iron.

Thermal Expansion Rates
Concrete frames and concrete masonry units shrink with time. Clay bricks, on the other hand, expand with time.
The different materials in your house are continually expanding and contracting, at different rates. A shrub's shadow can affect heat absorbtion. Here are the specific heat capacities of various building materials.
