Spray Foam insulation offers superior insulation compared to other materials. It creates an airtight seal, which helps reduce air infiltration and increases your home's energy efficiency. But where do you install it to ensure maximum effectiveness? Here, we'll briefly discuss the best place to install spray foam insulation in the attic.
Underside of Roof Deck
The ideal location to install spray foam insulation in the attic is on the underside of the roof deck. It should be right below the sheathing, where the rafters meet the roof decking. The space allows for a complete seal that creates a thermal barrier between indoors and outdoors.
But why is the underside of the roof deck the best place to install spray foam insulation? Here is why.
Spray foam insulation, especially closed-cell foam, creates an airtight seal. When installed on the underside of the roof deck, it fills all gaps and crevices, leaving no room for air infiltration. That means the cold unconditioned air from outside does not enter your attic, and the warm air from inside does not escape. As a result, your HVAC system does not have to work as hard, leading to energy savings and reduced utility bills.
Another advantage of installing spray foam insulation on the underside of the roof deck is its ability to control moisture. The seal created by the foam prevents moisture from entering your attic. The material is water-resistant, meaning it will not become a breeding ground for mold and mildew.
Controlled humidity is crucial as it prevents structural damage, improves indoor air quality, and protects your home's insulation. Moisture can also cause thermal bridging, which reduces the effectiveness of your insulation. Spray foam insulation in the attic helps tackle this issue.
Spray-foam insulation is an excellent choice for your attic, and installing it on the underside of the roof deck provides numerous benefits.
