Benefits of attic insulation

Your attic is more than just a place for storing broken furniture or discarded toys. Its ventilation system actually plays a huge role in determining the temperature of your house. It also provides support to your roof and adjacent structures.

If you haven’t visited your attic in a while, call roofing experts so they can properly insulate your attic. With the chilly air of autumn just around the corner, you wouldn’t want to miss out on the following benefits of attic insulation.

Better indoor conditions

Attic insulation helps you achieve optimal and comfortable temperatures. During cold months, it provides a layer of protection against the freezing temperatures outside by making your home cozy. Moreover, when you turn on the heater, your house’s insulation traps the heat inside, resulting in lower heat loss and more warmth.

Conversely, during summer, insulation blocks the sweltering heat that seeps into the roof and walls of your home. It also keeps the cold air from a fan or the AC from getting out.

When your house is underinsulated, it’s prone to temperature fluctuations. When it’s unbearably hot or cold outside, upper rooms or floors can become 10–15 degrees hotter or colder than those below. Thus, insulation is a great way to maintain consistent temperature around the house.

Lower utility bills

When your house is not insulated or is underinsulated, you have to turn the heater all the way up to make your living quarters cozy during cold months. And when it’s hot outside, you’ll need to power more fans or ACs to stay cool. By lessening the need to rely on heating, ventilation, and air conditioning (HVAC) systems, attic insulation can help you trim your utility expenses by up to 30%.

Longer-lasting house materials

Heat and moisture damage your house. Attic insulation protects your home by keeping water vapor from getting in and eroding your walls. In effect, it also stops mold from growing on — and eventually decaying — your pipes and plywood, since the former only thrives in areas where there is moisture.

Another way attic insulation protects your house is by preventing ice dams from forming in winter. These appear when parts of the attic or roof get warm enough to melt snow. The melted snow runs down your roof only to refreeze on the edge where it’s colder. Ice dams are a problem because they can cause your roof to sag and leak; it can also cause wooden parts of your house to rot. With attic insulation, your attic and the entire roof remain cold, so snow won’t melt and cause damage to your home.

On the other hand, during the hot months, attic insulation lowers the heat in your attic considerably, preventing the shingles on your roof from swelling and cracking. It also stops plywood from softening due to heat buildup.

Lastly, since insulation gradually changes the temperature inside your house, you rely less on HVAC systems and in effect, they experience less wear and tear. Your HVAC systems will last longer as they don’t need to work overtime to regulate the temperature around the house.

Better indoor air quality

Through air leaks in poor or old insulation systems, outdoor pollutants such as dust, mold, and mildew can invade your home and compromise air quality. Insulating your attic prevents harmful elements from entering and spreading throughout your home. Replacing old insulation can also remove pollutants that have been around for years. In other words, modern attic insulation lets your family breathe in cleaner, safer, and healthier indoor air.
