Choosing the right type of attic insulation for your home depends on so many location-related factors. In some areas of the country, you can have as many as five distinct climate zones! So how do you know how to insulate your attic best?
In most cases, a professional energy audit is a good way to begin. A professional energy auditor will assess your home’s internal ecosystem to evaluate its energy efficiency, which will cover the your current attic insulation. The auditor then tells you whether you should add more insulation or install a new system altogether.
Again, depending on the state you’re in, the U.S. Department of Energy will recommend the R-value that works best 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. Hence, homes in the northern parts need a bit higher R-values than those in the south.
Excess moisture in the attic insulation is yet another factor to take into account. Improperly vented appliances, minor roof leaks, and dripping water pipes all contribute to this moisture. These can reduce the R-value of the insulation, giving rise to mold and mildew growth, which can be hazardous.
Wrapping a home’s water heater and pipes with insulation can make a huge difference as well in terms of energy bills, particularly if the temperature in the heater area is low, or if the pipes pass through an unheated basement or attic.
Around 15 to 20 percent of a home’s monthly expenses are incurred from heating water. Additionally, insulation of water pipes will ensure that they don’t burst or freeze during the coldest seasons. It’s not hard to understand how good attic insulation can offer several long-term benefits for your home. In general, it will reduce your energy bills, make indoor temperature more comfortable any time of the year, and improve indoor air quality.
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 out there, but not all are created equal. Research goes a long, long way when deciding which one to choose.
