What does insulation do for your home?
Insulation in your home provides resistance to heat flow and lowers your heating and cooling costs. Properly insulating your home not only reduces heating and cooling costs, but also improves comfort.
What are the benefits of insulation?
Insulation acts as a barrier to heat flow. It can make your home more comfortable by reducing the amount of heat escaping in winter and reducing the amount of heat entering in summer. By insulating you can significantly reduce your heating and cooling bills and help to reduce greenhouse gas emissions.
Does insulation keep heat out?
Insulation is a Thermal Barrier Wearing a coat makes you warm because it prevents your body heat from dissipating. Heat always moves toward cold, not the other way around. This means if you run the air conditioner to keep your home cool in the summer, insulation helps keep hot air from making its way inside.
What is insulation and why is it important?
Insulation will help you keep the desired temperature in your house all year round, protecting it against cold in winter and excess heat in summer. Insulation is also useful to reduce noise pollution. A well-insulated house is very energy efficient and will need very little additional heating and cooling.
Where is insulation most important?
Arguably the most important space in the home to insulate is the attic. This is primarily because heat naturally rises, which means that the attic will hold a lot of the heat generated in the home. During the winter, having that heat escape through the attic will push up energy bills.
Where should you not put insulation?
Do not use fiberglass insulation in basements. Fiberglass traps mold well and basements are notorious for having moisture problems. Instead, use closed cell foam board and spray for basement installation. Never place insulation close to water heaters, oil burners or anything hot.
What are the disadvantages of insulation?
CONS
- Not waterproof and prone to moisture.
- Vulnerable to rot and mold when it gets wet.
- Not an air barrier, so it must be paired with air sealing to meet ENERGY STAR standards.
- Low R-value of up to R-3.7 per inch when compared to spray foam insulation.
What should I insulate first?
If you are looking at adding to an existing insulation, the attic is your best first step. Current codes are looking for a minimum of R60 which is about 2 feet of fiberglass in an attic area. For not a lot of money, you can have loose fiberglass insulation blown into your attic area through your attic access.
Can you over insulate a house?
It is possible to over-insulate your house so much that it can’t breathe. The whole point of home insulation is to tightly seal your home’s interior. But if it becomes too tightly sealed with too many layers of insulation, moisture can get trapped inside those layers.
What is the best way to insulate a house?
One way to insulate walls of an old house is to focus on the home’s exterior:
- Apply a house wrap/vapor barrier to exterior walls.
- Attach 1-inch foam board insulation.
- Install siding over the insulation.
- Replace old windows with energy-efficient units.
- Caulk window trim and use weatherstripping to reduce air leaks.
What is the most efficient type of insulation?
Spray foam insulation is the most energy-efficient insulation to create an air barrier in the attic. Certain spray foams can expand up to 100 times its original size, so it fills all of the nooks and crannies in the attic.
What type of insulation should I use?
Depending on where you live and the part of your home you’re insulating (walls, crawlspace, attic, etc.), you’ll need a different R-Value. Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces.
What kind of insulation is fireproof?
Fiberglass insulation is made of glass combined with plastic polymers and is naturally fire-resistant.
Can insulation cause a fire?
The amount of insulation in the walls and ceiling/roof of a room can affect the rate of growth of a fire. Insulation installed around the heat-producing device can cause the device to become overheated – if the device becomes hot enough, it can ignite combustible materials in contact with it.
