Ultimate Guide to Home Insulation: Introduction, Types, and Ways to Install It

People invest a large amount of money to ensure optimum home temperature year-round. Installing air-conditioners and heaters is common in the modern world. However, most people don’t realize the value of home insulation.

Hence, high energy bills and increasing carbon dioxide emissions are major issues. House insulation is an escape from it because the thermal barrier stabilizes indoor temperatures and lowers the load on HVAC equipment. It is a proven technique that boosts energy efficiency and cost-effectiveness.

In this write-up, let’s discover the meaning of home insulation, how to do it, types, benefits, and more.

What is House Insulation?

Insulation of the home refers to the use of methods and materials to create a thermal barrier inside walls, roofs, and floors of a house. It is more prevalent in urban areas just like vernacular architecture in rural areas. This method also known as home thermal insulation, aims to reduce heat loss or gain through the creation of a barrier between the walls of a home.

This system strives to maintain consistency in the temperature ensuring no consistent use for air-conditioners or furnaces. Gaps and holes in the walls, windows, doors, attic, crawl space, electrical outlets, and rim joists can cause airflow into or out of your home.

It can affect the performance of an air conditioner and heater and higher energy bills can ensue. Thus, home insulation is essential for every home, especially in extreme climates.

Types of Home Insulation

Fiberglass Insulation

As the name suggests, this solution is made of fiberglass and has gained popularity as it is affordable and effective. You can find fiberglass insulation in rolls or batts. It offers better thermal performance and soundproofing qualities.

Cellulose Insulation

Cellulose insulation is an eco-friendly choice as it is made from recycled paper products. Experts treat it with fire retardants to improve safety and blow it into wall cavities and attics. This type of home insulation reduces airflow and offers good coverage.

Foam Board Insulation

Foam board insulation has rigid panels which ensure high insulating value with minimal thickness. You can use this method to effectively insulate basement walls, foundation walls, and certain types of roofs. Foam boards are moisture-resistant and allow ease of installation.

Spray Foam Insulation

You can use Spray Foam Insulation method to spray foam into floors, walls, and ceilings. The foam expands to fill cracks and gaps ensuring an airtight seal. Reduced air leakage and improved energy efficiency are the benefits spray foam insulation offers.

Mineral Wool Insulation

Mineral wool insulation, also known as slag wool or rock wool, is made from industrial waste products or molten rock. Its excellent soundproofing and fire resistance properties make it an amazing insulation method. It is available in batts or loose-fill, and people often use this type of insulation where high-temperature insulation is required.

Insulation Sheets

It is a flat and large piece of insulation material that can be cut to adjust into different spaces. Insulation sheets offer a continuous insulation layer and are available in various materials such as aluminum and air bubble sheets. You can use these sheets to insulate walls, floors, and roofs.

How to Do Home Insulation?

Ways to Install Spray Foam Insulation

The spray foam technique facilitates insulating open areas such as rim joists, attics, crawl spaces, and pole barns. You can use this method to insulate open walls when the building is under construction.

Before installing spray foam in an existing home, remove the old insulation first. As a result, the spray foam gets to a clean surface to adhere to it. The foam is sprayed into an open cavity and open-cell foam expands up to 100 times more within a few seconds.

You can follow the same installation process for closed cells, however expansion rate is lower in closed cells. Also, remember that this method suits commercial buildings and pole barns.

Ways to Install Fiberglass Home Insulation

You can roll and fit fiberglass insulation between beams, joists, and studs during construction or remodeling of a building. This type of house insulation can be rolled into any part of the home. However, it is ideal to cover long unobstructed parts of the home like crawl spaces and attics.

Cut the fiberglass to fit in the installation area and roll it out. You can push the insulation into the cavity and pull it forward to fluff it to its full expansion.

Ways to Install Cellulose Insulation

Professionals use blown-in, dense pack, loose-fill, or wet-applied techniques to install cellulose insulation.

In the dry blown-in method, a machine blows cellulose into the attic. This process requires two people, one person blows cellulose into the area and simultaneously, another person feeds it to the machine.

Ways to Install Injection Foam

This type of foam easily injects into exterior walls from outside. In homes that have siding, professionals remove pieces to drill holes between the studs. After that, they inject the foam.

In brick homes, mortar is used to drill holes and then foam is injected. Additionally, experts use mortar to fill holes. You can also install injection foam in concrete block walls to fill the core of the blocks.

Benefits of Home Insulation

Boost Energy Efficiency

Home insulation provides a thermal barrier to ensure reduced heat transfer in and out of the house. This technique plays a significant role in keeping the home cool in summer and warm in the winter, which lowers the load on your cooling and heating systems.

This type of insulation sustains a certain temperature, and you don’t have to use cooling or heating systems more often. Hence, you can save lots of cost.

Reduce Noise

Insulation of the home empowers you to cut the amount of outside noise from entering your home. However, the insulation material must have sound-damping abilities. The people who opt for this technique experience car noise, dog barks, and other disruptions less often.

Enhance Comfort

The best advantage home insulation offers is to keep indoor temperature stable. It will protect your home from high temperatures in the summer and cold winds in the winter. A consistent temperature makes the indoor environment comfortable for the whole year.

Better Indoor Air Quality

Insulating your home ensures dust, allergens, draughts, and outdoor pollutants do not enter the room or house. Hence, you can have a healthy living environment with minimal respiratory issues and allergies.

Extend the Lifespan of Equipment

Home insulation is beneficial in reducing the workload of an HVAC system. Installing insulation in your house lowers the requirement for HVAC systems. Thus, you can save costs in multiple ways from maintenance, repairing to replacement.

Increase the Resale Value

Well-insulated homes are popular. These technologies are more energy-efficient, comfortable, and cost-effective in comparison to conventional technologies. Hence, you can get an increased resale value for your property.

Impact on Environment

Insulated homes experience a reduction in carbon emission levels as they consume less energy for cooling and heating. It translates into environmental sustainability and helps in combating global warming.

Where Can You Install Insulation in Your Home?

Walls

Professionals insulate outer walls to maintain consistent indoor temperatures. They insert home insulation walls in wall cavities or fitting rigid foam boards to insulate the walls of a home.

Attic

Insulation is the finest way to increase efficiency in your attic. This method prevents heat from entering the house in summer and vice-versa in winter. Blown-in cellulose, fiberglass batts, and foamed board insulation are ideal materials for this type of insulation.

Floors

You can employ batt or foam board to insulate spaces such as garages and crawlspaces.

Doors and Windows

Install home insulation to seal the gaps in doors and windows. It will make sure unwanted air does not come in and optimum temperature is maintained.

Roof

You should insulate your roof if it is low sloppy or flat and contribute to cost savings on energy.

Pipes and Ducts

Insulating pipes and HVAC ducts helps them maintain hot water temperature.

Conclusion

You must have understood that home insulation is a barrier to block heat transfer and ensures a bearable temperature in the home. Insulation is beneficial for both seasons as it does not let heat enter the house in summer. On the other hand, it limits heat loss in the winter. It contributes to saving money as well as power.
