Insulation is an essential part of any home, regardless of the climate you live in. Insulation, in combination with proper ventilation, helps to stabilize the temperature inside of your home so that it’s not too hot in the summer and not too cold in the winter.
Because attics are located at the top of the house, they are most exposed to and affected by the constantly changing conditions, especially in a climate like Toronto. And the attic is where the most amount of heat and cold is lost and gained. This is why homeowners should consider their attics as the topmost priority when thinking about insulating their homes.
When properly installed, attic insulation can significantly lower your energy bills because you cut the cost of heating and cooling your house. A properly insulated attic will also double the lifespan of your air conditioning and heating systems, given that they don’t have to work as hard in keeping a consistent temperature inside your house.
Mold formation and ice damming are due to improper insulation or improper ventilation, or a combination of both. Without proper insulation and ventilation, warm moist air that goes up into the attic gets trapped inside, causing mold growth.
In the winter, ice dams form due to trapped attic heat melting the snow on the roof. When the melting snow refreezes at the eavestrough, it creates a barrier and subsequent pools of water starts to back up inside the soffit and eventually inside the house. Click to read more about ice dams.
