Looking to Insulate Your Attic? Read These 4 Tips First
When it comes to saving money on heating and cooling, attic insulation should be one of your top priorities as a homeowner. In fact, improper or inadequate attic insulation is one of the leading reasons for lost heat in the winter and lost air conditioning in the summer.
Not only that, but improper insulation can cause your home serious damage. These problems include mold and mildew issues, and during the winter months, some attics may experience the formation of ice dams.
Ice dams can result in significant damage to your roof, resulting in additional repair and replacement costs that could have otherwise been avoided.
If you are looking to add insulation to your attic, you are probably already aware that it's a complex job. As a result, Georgian Insulation has listed four tips that will help get you started.
1 - Check your existing insulation
Before coming up with a new insulation solution, you should first find out the issues with your existing insulation. The first step of insulating your attic should be to get your existing insulation inspected.
Insulation can become old and worn out, losing its effectiveness, or in some cases, it may have been improperly installed. By finding out the exact issue, you’ll be able to make sure the same mistakes aren’t made again (if any, it may simply be wear and tear).
Quick tip: It’s important you get a professional to perform this inspection. Not only will they have the expert knowledge to know what insulation can be reused, they’ll also be able to find harmful materials such as Vermiculite insulation.
2 - What insulation do you need?
Whether you are adding to your attic’s existing insulation or installing entirely new insulation, you do not have to worry about using the same type of insulation that is already in your attic. In fact, you can use any type of insulation as long as it works for your property.
If you are adding fiberglass insulation over loose fill, it’s important to remember that the fiberglass batt has no paper or fill backing (unfaced). It’s also important to remember that if you choose to add loose fill insulation to your home you will require a blowing machine.
That piece of equipment can be rented from some home improvement stores, but most people hire a professional to install their insulation.
3 - Determine which R-value you need
An insulating material's resistance to conductive heat flow is measured or rated in terms of its thermal resistance or R-value - the higher the R-value, the greater the insulating effectiveness.
The R-value depends on the type of insulation, its thickness, and its density. By knowing your climate zone, you will be able to learn which R-value insulation range is best for your attic.
4 - How much insulation do you need?
Now you know exactly what you’re looking for, you’re probably wondering how much insulation you actually need to effectively insulate your attic. Surprisingly, there is a quick and easy way to check if you need to top up your insulation, or how much insulation you should add.
All you need to do is quickly look across your attic. You should be looking at your floor joists. You should have enough insulation so that your joists are completely covered by your insulation, and you should make sure that your insulation is distributed evenly.
If you find that you can not see your floor joists because your insulation is covering it, and your insulation looks evenly distributed, you probably have enough insulation in your attic.
You should also look for signs of damage from animals and weather. Animals that get into your home can move your insulation around, leaving cold, bare spots that can lead to ice damage, water intrusion, mould and general discomfort in your home.
