Does insulation keep heat out in summer?

The benefits of insulation in summer are similar to the benefits it offers your family in the fall and winter. Just as insulation prevents cold air from penetrating your cozy home in winter, it also prevents outside heat from entering in summer. The short answer is yes, insulating the attic is an effective way to keep the house cool during the summer months. While it's a fact that attic insulation will keep the house warm during the winter, it's not immediately obvious that insulation can also help keep the house comfortable during the summer. Once you control the temperature of the attic, the insulation keeps the rooms at a constant temperature.

It keeps the coldest air in the desired place in summer and prevents heat from escaping in winter. It's essential to ensure that insulation levels are adequate throughout the house. However, if you control your attic space well, you may not need as much insulation. In summer, however, the insulation works to keep the cold air inside and the warm air contained in the attic, where it naturally rises due to the “Stack effect”. The insulation acts to fill and block these cracks and gaps that have a negative effect on the overall energy efficiency of the house.

It takes a lot of energy to heat or cool a home, so insulation is a good investment to deal with the conditions that could result from a leaking home. The R value is the ability of an insulating material to withstand heat flow; the higher the r value, the greater the insulating power of material. When insulation works efficiently, it slows the movement of heat between two spaces and, in the process, effectively reduces the movement of moisture from the air, essentially creating an air barrier, an air seal to trap air, and a vapor barrier that inhibits the circulation of moisture through the wall, ceiling, and even the floor. Sometimes it can be difficult to know exactly what insulation to choose for your home, so it is always recommended that you contact a professional in your area to evaluate and estimate the attic and thus better decide, together, which attic insulation material best suits your needs and those of your home.

When you treat attic space with a radiant barrier, aluminum foil or copper to reflect heat, or add tons of airflow to achieve good air exchange there and keep the heat down, you control most of your home's exposure to the sun from top to bottom.

Attic air conditioning and ducts are destroyed every summer due to high heat and lack of air flow in the attic.

Helps improve indoor air quality: When insulation fills or blocks small gaps and cracks in the house that lead to the outside, it not only helps keep the house cooler in summer, but it also prevents potential allergens and toxins from entering the house.

In addition to attic insulation, there are many other factors that can influence the overall energy efficiency of the attic. Attic insulation works to absorb the heat produced by heating systems during the winter months and, conversely, it can prevent warm air from spreading around the house from the attic, where you will notice the highest peak of heat during the day during the summer. After controlling the temperature of the attic and insulating it properly, it's time to surround windows and doors and take care of any cracks or spaces through which sunlight can enter.
