Canadian houses – insulation and heating – wooden houses are popular in Canada and the United States. They are considered cheap, energy-saving and quick to build. In our country, they are rather reserved due to the fact that many people do not know whether wooden buildings will cope with Polish climatic conditions, cold winter or windy, rainy autumn.
As a rule, when we decide to build a Canadian house, we use it as a cheap summer house, without installing additional insulation. Hardly anyone decides to build a year-round Canadian house due to heating problems. Below is some information on this.

Wood and temperature
Canadian homes cool down faster. This is due to the wood itself, which is not a material that maintains a constant temperature. Wood does not store heat, which is why wooden houses cool down faster. At the same time, they also heat up faster, which means that we need much less energy to heat such a house.
What is worth mentioning, wood is not completely useless in stabilizing the temperature. Wood has thermal insulation properties. The thermal resistance of wood is variable, which means that the Canadian house guarantees better thermal insulation when it is colder outside. This is a property of wood that is easy to use with modern technology. The latest ways to insulate buildings mean that Canadian houses can behave similarly to brick houses.
Insulation of a Canadian house – what to use and what to avoid?
When we think about good insulation, most often we think of polystyrene. However, for Canadian homes, this is a bad idea. Mainly because polystyrene is not a vapor-permeable material, and this may result in faster destruction of wood in the future. For insulation of wooden houses, materials that do not retain moisture should be used, because otherwise the wood will start to rot, mold and fungus will appear.
Instead of polystyrene, it is better to use mineral wool. The material is waterproof, fireproof and less susceptible to mechanical damage. In addition, it is also used as sound insulation. Dampens crackling and other noises typical of wooden floors and walls. Mineral wool is air permeable, so it does not contribute to the formation of mold.
When it comes to choosing mineral wool, we will have to decide on one of two types: rock wool or glass wool. The first type is made of dolomite, basalt, lime aggregate or recycled mineral briquettes, while the second type is made of quartz sand and recycled glass cullet. Of these two possibilities, investing in glass wool seems to be a much better and cheaper option.
In addition to mineral wool, another popular form of insulation in Canadian homes is a vapor permeable windproof foil, used from the outside. Protects against wind and moisture. Vinyl or wood siding is used for the exterior finish.
In the case of insulation, its type and amount depends on our decision. For example: some people use additional insulation of the walls from the inside, protecting them from moisture from inside the house. The method of construction of Canadian houses allows for various protections. Remember, however, that each protection should be installed by a specialist, because errors in the installation of insulation can have serious consequences.
Canadian houses – heating
A traditional heating system based on radiators or underfloor heating works by heating the surface of the walls/floors, which later “give back” the heat, raising the temperature in the room. That is why traditional houses, made of bricks that accumulate heat well, heat up for a long time, and then maintain the temperature for a long time. In the case of Canadian houses, this type of system would be extremely uneconomical and quite unreliable. Wood does not hold heat, so to maintain the temperature, you would need to heat the house all the time, even with small fluctuations in temperature.
Canadian houses are best heated using a blow-in system. In this system, the heat from the fan is sent through air supply ducts with a grille. Placing them in key places in the house will ensure quick and effective heating. To choose the right places, it is worth consulting an architect.
When it comes to the boiler itself, the most important thing is that it is adapted to the installation. We can, for example, use a fireplace, although in its case it is impossible to control the temperature. Another solution is an electric boiler or a fuel feeder. With this choice, we can easily set the desired temperature or we can set it to turn on and off from time to time. This will save more energy.
In addition, the blower system can be adapted in such a way that it not only heats the measurement, but also moistens it. Duct air humidifiers can be installed in the heating system, which will eliminate the problem of unpleasant, dry air.
