Upgrading to well-insulated buildings benefits owners, tenants and the environment in many ways. It increases energy efficiency and reduces reliance on fossil fuels, decreasing greenhouse gas emissions.
Sealing air leaks and adding insulation can save homeowners an average of 15 percent on heating and cooling costs and 11 percent on total energy costs. There are many insulating options, with different R-values and materials.
Reduced Energy Bills
Insulation slows the flow of heat through walls, floors and ceilings. It prevents hot air from escaping during the summer and helps keep warm air contained in the winter, which reduces energy bills. In addition, it can help homeowners to reduce their reliance on fossil fuels such as oil and gas by lowering the need to heat and cool the home or office.
A home that is poorly insulated or has air leaks can waste up to 15% of its energy. Insulation and air sealing significantly cut energy costs for heating and cooling, which pays for itself many times over the life of the insulation.
Properly installed spray foam insulation in attics and other areas of the home can reduce a building’s energy bills by 20 to 30 percent. The savings come from the lower use of energy to heat and cool, and from the reduced wear and tear on heating and cooling systems.
In addition, a well-insulated home will be quieter because it reduces the amount of outside noise that is transferred into the living space. Insulation also blocks the migration of outdoor contaminants like dust and pollen into the house, which can trigger asthma and allergies. This helps to create a healthier environment for families to live in.
Increased Property Value
Regardless of the age or style of your house, installing proper insulation can increase its value. In fact, homeowners who install insulation often recoup the money they spend on it through lower utility bills and a higher resale price for their home.
Insulation protects against the penetration of cold air in winter and excess heat in summer, allowing you to maintain a more desirable temperature throughout your house without using as much energy. A properly insulated house also needs less maintenance and is safer and quieter.
There are many different types of insulation, ranging from bulky fiber materials to sleek foils. Most insulation is rated by its ability to resist the flow of conductive heat; this is known as its R-value. The R-value of insulation varies with the type and thickness of the material, as well as the moisture content.
When adding insulation to existing homes, it is best to hire a professional. However, some homeowners choose to do their own insulation installation projects, following the manufacturers’ instructions and safety precautions. The most common insulation, called blanket insulation, comes in rolls or sheets that contain flexible fibers, typically fiberglass. Other options include mineral (rock and slag) wool, cotton, and cellulose. For new construction, consider structural insulated panels (SIPs), insulating concrete forms, or insulated wood framing. These prefabricated products provide superior and uniform insulation compared to traditional wood stud and stick frame construction, while reducing the cost of building and saving energy.
Reduced Environmental Impact
If you have noticed your energy bills increasing without any change in your energy consumption habits, it could be a sign that your home’s insulation is outdated or damaged. Proper insulation will balance the temperature in your house and prevent heat loss, thus reducing energy costs.
When a building is properly insulated, it reduces the demand for fossil fuels used to generate power. This reduces greenhouse gas emissions into the atmosphere, contributing to a more sustainable environment.
Wall insulators slow down the rate of heat transfer and restrain it within a room, which reduces the need for air conditioning units to use power to achieve and maintain a comfortable indoor temperature. They also act as barriers to external noise pollution, providing a quiet and peaceful interior environment.
Since most of your energy costs are tied to heating and cooling, proper insulation can significantly lower these expenses. By limiting the transfer of heat and preventing unwanted air movement, your home’s HVAC systems will be forced to work less often, resulting in significant savings on your energy bills.
In addition to lowering energy bills, proper insulation can significantly reduce unwanted condensation and mould. It is also effective in reducing the penetration of outdoor air pollutants, allergens and dust, ensuring a healthy indoor environment. This can have a positive impact on people with sensitive respiratory problems.
Increased Comfort
Insulation is the material used to keep heat, sound, and electricity from spreading. For example, your thermos of hot chocolate stays warm because it has insulation. Insulation also keeps your home more comfortable. Insulation prevents heat from escaping your home in the winter and makes your furnace work less hard. The energy savings can pay for the cost of insulation in less than a year.
In addition, insulation and air sealing prevents drafts and excessive moisture in your home. This reduces the spread of mold, which can have a very negative impact on your health. It also reduces the need for expensive re-decoration costs.
Upgrading your homes insulation will give you a more comfortable place to live all year round. This will cut your energy bills and help to keep the environment cleaner.
If you are building a new house, consider insulated concrete blocks or structural insulated panels. These materials have insulation built in, and they provide a more efficient way of framing a home. They help to eliminate thermal bridging through wood studs and maximize the insulating value of a house.
Insulation is a vital part of any modern home. Without it, your home can become very cold in the winter and extremely warm in the summer. Insulation creates a barrier that stops heat from entering your home in the winter and keeping it out in the summer. This allows you to use your heating and cooling systems less, which saves money on your power bills.
