What can attic insulation and proper ventilation do for your home? It can make the inside of your home more comfortable year round and protect it at the same time—and all while decreasing the use of your thermostat.
Most people know the benefits of insulating the attic. Insulation helps keep the warm air inside during the winter and the cool air inside during the summer. It also prevents the outside temperatures from infiltrating the air inside your home’s envelope while also lowering energy costs and keeping your home comfortable.
Ventilating the attic is almost as important as adding insulation to it. It helps protect your home from damage. Hot air in the attic during the winter can cause damaging ice dams. As ice and snow settle on the roof, it melts because of the hot air in the attic below. However, as it reaches the edge of the roof and starts to enter the gutter, it refreezes, causing an ice dam. This can damage the edge of the roof.
Super hot, humid air can build up in the attic during the summer. The built-up moisture levels can cause damage to the roof shingles and decking above.
Attic Ventilation Options
- Rafter ventilation – Along the top of the roof, a ridge vent allows hot air to escape. To bring in cooler air, rafter vents are installed along the soffits. The air enters through there and evacuates the hot air out of the attic.
- Attic fan – This fan will draw cooler air in and help to expel it out of the ridge vent. The attic must have good insulation and air sealing, however, to prevent conditioned air from being drawn out of the home.
