Insulation creates a barrier between your home and the outside environment. During winter, it will keep heat inside your home, while during summer, it will keep heat outside, making your home more pleasant. It’s a principal factor in lowering your energy bills. The less hard your heating and cooling systems work, the more money you save. And using less energy is good for the world.
Good insulation can also make your home quieter. If you work at home or have a child who takes naps during the day, this will be a welcomed benefit.
Proper insulation can increase the value of your property. Many potential homebuyers see energy efficiency as a positive feature, which can give your home more appeal when you sell it.
Types of Insulation
Fiberglass, possibly the most common insulation material, comes in batts, rolls, or loose-fill (which can be blown into areas behind walls and in attics). Made of fine glass strands, it traps air layers between them, resulting in outstanding thermal resistance. It is relatively inexpensive, non-combustible, and resists moisture. Fiberglass insulation is fairly easy to install. It can simply be laid or blown into open spaces in places like basements and attics that are not finished. When doing so, you should wear protective gear, as the fibers can irritate your skin and lungs. Always cover your eyes, nose, and skin when working with this material.
Foam board, or rigid foam panels, which provide versatility and exceptional thermal resistance. They are frequently used in basement walls, under floors, or even exterior walls. These boards, which are available in a variety of thicknesses, are usually made from polystyrene, polyisocyanurate, or polyurethane. Installation is more hands-on, requiring cutting of the panels to size and sealing with tape or foam sealant at the seams to prevent air leaks. If you have some basic DIY skills, foam boards are lightweight and simple to work with. They’re excellent in tight areas where other types of insulation may not easily fit.
Spray foam insulation is perfect for hard-to-reach places. It expands when applied, filling gaps and forming a strong seal. It is ideal for air and water barriers. There are two types of spray foam insulation: open-cell and closed-cell. Closed-cell foam is denser and has a higher R-value, so it is a more effective insulation. Despite the good benefits of spray foam insulation, it’s best to leave the job to professionals, given the necessary equipment and expertise. In addition, the chemicals used in spray foam can be dangerous during application, it is essential to wear protective gear and ensure adequate ventilation.
If you want something eco-friendly, you might consider cellulose. Made primarily from recycled paper products, this type is usually found in loose-fill form and can be blown into wall spaces or attics. It is treated with a fire-retardant substance, so safety is not a concern. Cellulose offers excellent cost-performance value. It provides good thermal insulation and acceptable soundproofing. The installation requires the use of a blower, which you may be able to rent for free at a home improvement store if you’re willing to do your work.
How to Choose the Right Insulation
In extremely cold areas, you should use insulation with a high R-value, which means better thermal resistance. Insulation that effectively blocks heat but may have a lower R-value can be adequate in hot climates. In warm areas, reflective or radiant barriers can also be helpful, as they reflect heat away from the house.
Not every area of your home needs the same amount of insulation. Start with the attic, where you will find the most heat transfer. Next, insulate the basement and crawl spaces, which can contribute to moisture issues if left undone. Then, move on to the walls and windows.
It’s easy to get carried away buying the best and highest-priced insulation possible. You should consider your budget. Often a mixture of various kinds of insulation located in different areas of the home is best. Sometimes less expensive options, such as fiberglass batts, can be just as effective as spray foam, depending on the situation.
Installation Process
If you’re skilled with tools and don’t mind a bit of dirt, you can handle some insulation jobs solo. This includes fiberglass batts, rolls, and certain types of foam boards. Just be sure to wear the proper protective equipment—gloves, goggles, and a mask, for example.
Measure your areas and cut the insulation pieces to size for a neat fit. When working in walls, place the batts or boards carefully and fasten them in position with a staple gun or adhesive. Seal all seams and edges with the proper materials for maximum efficiency.
Leave spray foam jobs or jobs in very tight or hard-to-reach places to the pros. Spray foam needs special equipment and exact application methods to avoid thermal bridging and safety issues.
Professional insight could be useful for intricate installations where compliance with codes and safety is very important. A well-experienced contractor will be familiar with local building codes and best practices and will ensure the quality of your insulation.
The Impact on Energy Efficiency
A well-insulated home would need less heating and cooling. Since these systems are typically the biggest energy users in a house, any reduction in their operations would result in lower electricity or gas bills. Over time, the savings would be enough to cover the initial expenses of insulation.
Less consumption results in less fossil fuel burned, which, in turn, lowers greenhouse gas emissions. If you are trying to go green, the combination of top-grade insulation with other energy-efficient upgrades to your home can make a big difference.
Comfort is greatly enhanced in your home with proper insulation. A room’s temperature remains even without cold drafts or hot spots. This balance creates a more nice living space and may also contribute to better sleep and health.
