Why Attic Insulation Is Important
Attic insulation can help you bring down energy bills during winter as well as summer. Your home uses less energy to achieve its optimal temperature so you save cash and have smaller carbon footprint!
Since the attic is probably the easiest to insulate, it is where weatherization changes begin. You start by insulating the attic. As soon as it’s done, you move on to other projects. Once the attic is perfectly insulated, air can’t escape and the outside air can’t come in through floors and walls. Naturally, your energy bills go down.
Heating and cooling usually takes up to 70% of the total energy being used in a regular home in America. That means if you insulate your home you are going to bring down this number and reduce overall energy use in your home.
How Attic Insulation Works
Attic insulation prevents hot air from entering your home during the summer when you want to keep indoors cool. Since the climate is normally hot during summer and your home will be relatively cool, heat will naturally flow into your house as hot air as heat moves from hot areas to cool areas. Similarly, this happens in reverse during winter. Heat flows to where it is absent. If there is no insulation, it will be difficult to achieve to achieve your desired temperature indoors without having to push your heating/cooling system to its limits.
Insulation doesn’t only block outside air from entering the home or inside air from escaping the home but it also traps air in the insulation. This air trapped inside attic insulation will ensure that minimal heat flows through the attic.
Insulation material used for attic insulation comes in different ratings. These ratings are called R-value, which is actually thermal resistance. Insulation with higher R-value will perform better compared to one with lower resistance.
Selecting An Insulation For Attics
When it comes to choosing the right type of insulation for your home, the list of options is long. Each type of insulation has its advantages as well as disadvantages. The best way to find what’s right for your home is to look at pros and cons first, then discuss with an expert.
Batts And Rolls
These are fiber sheets which are extremely flexible. This insulation is fitted within wall studs and joints. You can even make this insulation fit into uneven places due to its flexibility.
Batts and rolls type of insulation is usually not resistant to flames but you can easily types that are fire resistant.
Blown-In Loose Fill
This type of insulation is also made from fiber sheets but it's loose fiber consisting of pellets. These pellets are blown in to the attic so that it can get into gaps and spaces easily and create an insulatating layer. This type of insulation is perfect for unfinished floors.
This insulation is made from foam that can be sprayed into walls. The foam then settles into gaps and cavities to insulate them. This insulation is applied using special equipment after mixing it with a chemical that "glues" it in place.
