Heat and cold are the natural enemies of your home, and windows are the most vulnerable part of your house. They let in heat in summer and cold in winter, letting them steal away much-needed warmth and comfort from your home. That's where insulation comes in, helping you keep your house warm or cool, depending on the season.
When looking for better roof insulation, there are several things to think about. Different types of insulation can be found on the market, and some are much better than others. While it may seem like a simple thing, you will find that many factors go into choosing the best type of roof insulation for your home.
Benefits of roof insulation
Everyone knows that insulation helps keep your home warm in the winter and cool in the summer. But did you know it can also help to keep your house cool during the hot summer months and prevent your roof from leaking in the winter? Here are some of the benefits of roof insulation:
- Energy efficiency: Insulating your roof can reduce the amount of heat lost from your home so that it can reduce your heating costs. It can also help keep the temperature inside more stable and comfortable. In a properly insulated attic, the temperature should be about the same as outside.
- Peace of mind: No one wants to be concerned about their home during winter because they know how cold it can get, but this becomes less of an issue by installing insulation on the roof. You won't have to worry about keeping the heat on at all times during the winter or being overly concerned about drafts coming through into your home.
- Reduced risk of leaks: Insulating your roof can considerably reduce the risk of leaks. You can take advantage of a free checkup from a qualified professional who will determine whether your home is at risk or not.
- Heat retention: In addition to preventing leaks, an insulated roof can help keep heat inside the house. At night, this can make it easier for you to get to sleep and wake up feeling refreshed since you won't constantly be switching between hot and cold temperatures.
- Heat prevention: Insulating your attic can help prevent heat from leaving your home altogether, which keeps your energy costs down in the winter and air conditioning costs down in the summer. This makes it easier to save money on heating and cooling bills every year.
- Added protection: Installing insulation on top of your old roof may extend its life by several years. This means that you don't have to worry about replacing it for a long time. You also won't have to worry about leaking mold or mildew growth problems.
Materials Used in roof insulation.
Many different materials can be used to insulate the roof of a home. Certain materials should be used for certain roof sections, as some materials are better suited than others for different locations.
- Fiberglass insulation: is made from glass fibers, which are formed into a matting material. Fiberglass can also help save on air conditioning bills as it reflects radiant heat off a building's roof and walls. Fiberglass insulation is considered environmentally friendly because it contains no formaldehyde or harmful chemicals.
- Polyurethane foam: is an insulation option that has gained popularity in recent years. Foam insulation provides excellent thermal performance but may not provide the same sound reduction as fiberglass insulation. It is also more commonly found in spray foam applications than batts or rolls.
- Polystyrene insulation: is made from petroleum and has a high risk of outgassing formaldehyde, a carcinogen that can cause respiratory problems and other illnesses.
- Foam rubber insulation: is made from recycled rubber tires and is generally considered safe. It has excellent sound-dampening properties and moderate fire resistance.
- Cellulose: Cellulose insulation is made from recycled newspapers that have been treated with borax to kill insects, mites, and larvae that could be present in the paper and cause damage to the home or health problems for occupants
- Mineral wool insulation: is made of minerals including basalt, diabase, and limestone, but it too has the potential for outgassing. Spun glass wool does not release formaldehyde but releases toxic gasses when exposed to fire.
How To Pick The Right Insulation For Your Household
The importance of having the right type of insulation material for your home cannot be overemphasized as it helps keep your house warm during cold weather and cool during hot weather. Here are the factors to consider when choosing the right one for your home:
- Flammability: Some types of insulation contain chemicals that can easily catch fire if they come into contact with fire or other flammable objects. This means that you need to be careful when choosing insulation for your house.
- R-Value: The R-value of your insulation is the measurement of resistance to heat flow per inch. The higher the R-value, the more effective the insulating properties. For instance, most fiberglass insulation has an R-value of 3 or 4 per inch. Cellulose insulation has an R-value between 4 and 6 per inch. Foam board insulation typically has an R-value between 6 and 8 per inch, depending on the type of foam board used.
- Allergens: One of the most important questions to ask yourself is if you suffer from allergies. Suppose you're one of the millions of Americans who experience allergic reactions triggered by airborne irritants like pollen and dust mites. In that case, you know that allergens can be a serious problem in any home environment.
- Installation cost: It is easy to say that installing fiberglass batts or other insulation material will be much cheaper than installing blown-in fiberglass or cellulose, but that is not always the case. A lot depends on how recently it has been installed, whether any damages or repairs are needed, and whether it makes sense to maintain existing insulation instead of replacing it.
- Durability: When you choose something like cellulose, it can be blown into your home quickly and easily. This means that it will probably not be as durable as other types of insulation, such as fiberglass batts or rock wool.
- Soundproofing: It helps to keep noise out and to keep noise in. This is an important factor when choosing a type of insulation to use around your home.
