Insulation is an essential but often overlooked component of your heating and cooling system. While many homeowners know that it helps keep warm air out of their homes in the summer and retain indoor heat during the colder months, they have no idea that a time comes when it’s crucial to start replacing insulation.
The Need to Replace Insulation
Several factors make it necessary for you to replace your home insulation:
Loss of effectiveness — Insulation deteriorates over time. Consequently, it could allow heat gain in the summer and heat loss in the winter. Maintain structural integrity — Your attic insulation can damage your home’s structure. If you ignore it for long, old insulation can facilitate mold and rotting of beams. Health — Rodents can make old or damaged insulation their home and leave behind harmful contaminants. These contaminants can spread to other areas of your home and put your health at risk. When to Replace Insulation
So how do you know it’s time to replace insulation? The tips below will help:
The insulation in your home acts as its primary defense against temperature change. Depending on its structure, it may have just one or two types, but if you need to add more, you may have more choices appropriate for the exact places where you need it.
Rolled fiberglass batts are the most common type of insulating materials used in new home construction because they’re effective, affordable and easy to install. Recycled denim and rock wool (also known as mineral wool) batts are also available. Rock wool is made by melting rocks.
In new construction, batts are used in attics, walls and basement or crawl space ceilings. They’re used in existing homes to insulate attics and unfinished ceilings. Loose
Cellulose, rock wool and fiberglass are the most common blown-in types of insulating materials. Cellulose is made from recycled newspapers and treated with borates to prevent insect invasions, repel moisture and retard fire. Of the types of loose insulation, cellulose is the heaviest and tends to pack down.
Many homeowners are unaware of the importance of adequate attic insulation. Inadequate insulation can be responsible for drafts, high utility bills and unexplained heat loss. Here is some basic information about attic insulation to help you understand how it can benefit your home.
Rolls and batts are generally made from rock wool or fiberglass. Their flexibility makes them practical for placing between attic or floor joists and between wall studs. Loose-fill insulation is a type of attic insulation made from fiber pellets or strands created out of fiberglass, rock wool or cellulose. Specialized pneumatic equipment makes it relatively easy for technicians to blow the loose insulation into oddly-shaped or hard to reach spaces. Rigid foam insulation is more expensive than loose-fill, roll or batt style insulation, but it works well to insulate exterior walls or along openings, such as attic doors. It is twice as effective as the same amount of other kinds of insulation. Foam-in-place insulation is practical for out of the way locations and small spaces. The chemicals come out of pressurized spray cans to fill openings in walls and window or door frames, preventing heat loss and cold drafts. Is There Enough Insulation?
In most homes, heat loss is a major source of wasted energy and money. Here is a brief explanation of residential heat loss and what you can do to correct the problem.
Problems from Heat Loss
Reduced indoor comfort: Heat loss means there will be areas with inconsistent temperatures inside your home. Some spots will be cooler than others, reducing overall comfort. Extra expense: When heated air leaks out of your home, you not only lose that air, but you have to pay to heat more air to make up for the loss. This means you pay more than necessary to heat your home. Unneeded wear on equipment: As it works to make up for heat loss, your heating system endures unneeded wear and tear. Overworked HVAC equipment is more likely to malfunction or fail, requiring a costly repair. Extra wear will also reduce the equipment’s functional lifespan.
Fixing Heat Loss
Find and seal air leaks: Locate holes, cracks and gaps where warm air can leak out of your home or cold air can get in. Seal these openings with caulking. Typical areas where air leaks occur include around door and window frames, at points where pipes or wires penetrate …
Proper home insulation is essential for energy efficiency in your Peachtree City home. There are several parts of the home where you need adequate insulation to prevent hot or cold air from escaping. Make sure you’re covered in these areas.
Hot air naturally rises, and your attic may end up harboring more than its fair share of your warm air in winter if it’s not properly insulated. Likewise, attic insulation will keep warm air out in summer, allowing you to maintain a cooler home below. Batt or loose-fill insulation are the best options for an attic.
Check whether your ducts are in a conditioned space or not. If they’re not within your air-conditioned space, you should insulate them. Foil-faced fiberglass home insulation is the best choice. You should also have your ducts sealed to minimize air loss in this area.
New homes often include insulation in the walls, but an older home may be lacking in this important area. You can look for insulation by prying back molding and taking a peek at what’s visible in the gap between the wall and the flooring. If you don’t have insulation in your walls, blow-in insulation is …
