Do You Need Attic Ventilation With Spray Foam Insulation in Woodstock?

do you need attic ventilation with spray foam insulation

Your attic plays an important role in maintaining the temperature of your Woodstock home, but it doesn’t do it alone. Insulation helps keep your home warm in the winter and cool in the summer, trapping the conditioned air inside the house. Without proper insulation, your home would be uncomfortable, and the energy bills would skyrocket.

You can install several types of attic insulation, including spray foam insulation. Do you need attic ventilation with spray foam insulation? In this guide, Anthem Insulation & Home explains what to know about spray foam insulation in Georgia and the benefits of attic ventilation.

Spray Foam Insulation in Woodstock: What Is it and What Does It Do?

Spray foam insulation is a type of home insulation made of isocyanate and polyol resin. When these two chemicals mix, they make polyurethane, a foamy material that creates a barrier between your indoor air and the elements outside.

Spray foam insulation comes in two different forms:

  • Open cell spray foam: Airy polyurethane cells that are soft and billowy
  • Closed cell spray foam: Tighter, more condensed polyurethane that creates an air-tight seal

The type of spray foam you choose depends largely on your insulation needs and budget. Open cell is a more affordable option, but closed cell is more durable. Both work well to insulate homes in Woodstock and reduce energy costs.

The Benefits of Vented Attics with Spray Foam Insulation

Do you need attic ventilation with spray foam insulation? If you have spray foam insulation in your home, attic ventilation is not a necessity. With that said, unvented attics compromise the integrity of your roof and hold moisture within the space.

Having attic ventilation offers several benefits for your home.

Energy Efficiency

Proper attic ventilation reduces energy costs by transferring air out of the home. This may seem counterintuitive, but natural airflow in an attic moves hot air out of the home in the summer, causing your AC unit to work less hard for an air-conditioned space. HVAC units that don’t have to work as hard due to ventilation and insulation can reduce your utility bills.

Roof Protection

When an attic is too humid, the excess moisture compromises the integrity of your roof. Roof repairs are costly, so keeping your roof strong is essential. This is especially true in Woodstock, where summers are exceedingly hot. 

Attic ventilation reduces the heat and moisture in a well-insulated attic, keeping the roof in good shape.

Prevents Mold and Mildew

While your spray foam insulation keeps the attic space warm during winter, too much heat fosters mold and mildew growth in the attic flooring, walls, and ceilings. Mold and mildew cause serious health concerns that affect anyone living in the house. Vented attics reduce warmth and moisture, creating a less hospitable environment for mold and mildew.
