What is a Building Envelope and Why is Insulation so Important in Winter?

A house in the snow

Winters in Canada are tough. From freezing rain, to snow and ice, your home has to keep your family comfortable and withstand the brunt of nature's weather.

You might be familiar with the term "building envelope", the physical separator between your inside 'conditioned' environment, and the outdoors. The building envelope is responsible for withstanding wind, water, heat, light and even noise.

At the heart of the building envelope is the control function - rain control, air control, heat control and vapour control.

Air flow is important to make sure your indoor air quality is healthy, your energy consumption is not excessive, and to avoid condensation and dampness. Air control includes the control of cold air passing through the insulation and convection loops within structures such as walls or ceilings.

Why is insulation important when it comes to your building envelope?

Residential insulation is a critical part of the physical components of your building envelope. How durable and effective your system is depends on insulation materials, installation and amounts, and the interactions between parts of the building envelope system.

Components such as the vapour barrier are important because moisture control or damp proofing is critical in cold climates, where there is a steep temperature gradient between the indoors and the outdoors. The thermal barriers or heat control layers are located within the building between areas that are heater and not. For example an insulated attic floor is the primary thermal barrier between your interior and exterior.

During the winter your building envelope is being tested daily by severe weather and fluctuations in wind, moisture, and temperature. Heating, cooling, freezing, melting are all occurring in your building envelope. If you have a well designed, efficient, quality system, then your home will be comfortable throughout the season.
