Renovating a home is an important project that deserves deep thought. Where to start? You need to set the renovation goal, determine the budget, and then draw up the plans before you get started. Insulation work is one of the most important. Let’s look at five reasons why.
In a poorly insulated house, the temperature inside is conditioned by the temperature outside. In the summer, you need a slight coolness. But it’s just as hot inside as it is outside. The purpose of insulation is to keep the warm air out and the comfort in. Conversely, a well-insulated house has a warm envelope in winter and provides a barrier against the cold outside.
As a reminder, a poorly insulated roof lets 25% to 30% of the heat escape. Heat loss is as high as 25% from the walls, 10 to 15% from the windows, and 7 to 10% from the floor. You also gain acoustic comfort.
Reducing energy consumption
In a well-insulated house, thermal comfort is optimized in summer and winter. This means that you need to use heating and air conditioning equipment less often, reducing your energy consumption. Heating and air conditioning expenses represent a significant portion of a household’s operating budget. With insulation retrofits, you have the opportunity to reduce your annual budget by about 30%.
Adding value to your home
Insulation work adds value to a home, especially in this day and age when being green and reducing energy costs are top of mind. Having a well-insulated home makes it easier to negotiate the price of selling or renting. New homeowners or renters will be more than happy to live in a comfortable home with less need for heating and cooling equipment. In addition, insulated attics provide additional living space.
Only the energy performance diagnosis will determine your home’s insulation level of efficiency.
Opt for a sustainable investment
Insulating a house is a substantial investment. Insulation has a lifespan of at least 20 years. Your energy bill will also decrease during this period.
Here is the average life expectancy of insulating materials:
- cellulose wadding limits heat loss for up to 40 years but begins to settle after 20 years
- polyurethane and polystyrene, although less efficient, will last more than 50 years,
- the efficiency of rock wool is very variable, ranging from 15 to 50 depending on its shape, even more in the best conditions,
- glass wool lasts 20 to 30 years,
- exfoliated perlite has an exceptional lifespan, as yet undetermined, as does vermiculite,
- hemp wool lasts between 40 and 50 years,
- expanded cork also lasts up to 50 years.
Taking care of the aesthetic side
Although aesthetics is not the main objective of home insulation, it can contribute. You have a wide choice of materials and finishes. These include exterior thermal insulation or siding. The latter is known to bring a new style to the building.
Living in a well-insulated house means limiting the use of heating and cooling equipment. By reducing energy consumption, you are also helping to protect the environment. The State continues to offer assistance for energy renovation.
