When it comes to choosing the right type of attic insulation, considerations vary, depending on location. In some areas of the country, you can have as many as five distinct climate zones! So how do you decide which type of attic insulation suits your home perfectly?
A good way to begin is usually with a professional energy audit. A professional energy auditor will look into your home’s internal ecosystem your to check how energy-efficient it is, including your current attic insulation. The auditor will then decide if you have to add more insulation or actually replace the whole thing.
Again, on which state you live in, the U.S. Department of Energy will recommend the most suitable R-value for your attic insulation. The R-value measures thermal resistance, or simply the amount of insulation that can impede heat flow.
The higher the R-value, the better the insulation capacity and the greater a home’s energy efficiency will be. The exact location of your home will also be a factor in determining the best R-value for your attic insulation.
For example, in some states, temperature differences between its northern and southern areas are the most significant during winter. That means properties in the state’s northern parts will need slightly higher R-values compared to those in the southern areas.
Another factor to consider is the presence of excess moisture in the attic insulation. Such moisture usually comes from dripping water pipes, tiny roof leaks and appliances that are improperly vented. These can pull down the insulation’s R-value and lead to the proliferation of mold and mildew, both threats to health.
Another thing that can increase a home’s energy efficiency is wrapping the water heater and pipes with insulation, particularly if the heater is in a cold section of the home, or if some of the pipes are located in unheated areas.
About 15 to 20 percent of a home’s monthly energy costs come from heating water. Additionally, insulation of water pipes will ensure that they don’t burst or freeze during the coldest seasons. It’s easy to see that proper attic insulation can provide a lot of long-term benefits to your home. To name a few, it can improve indoor air quality in your home, maintain comfortable indoor temperature, and of course, reduce your energy costs.
From a bigger perspective, good attic insulation will reduce your home’s carbon footprint because of the lower amount of energy you will need for heating and cooling. Sometimes, there are earth-friendly insulation options available, such as those made from cotton or recycled materials.
In any case, spend time searching for a competent and trustworthy provider of attic insulation services. There are many options out there, but they are not all the same. But if you do your research, you can choose smart and easy.
