Spray foam insulation can create usable attic space, improve your homes air quality, and reduce your energy bill!

The attic is a room often overlooked because they’re generally hot, humid, and just not a place you want to spend much time. But this area can be a great addition to your home’s usable space if insulated properly! What would you do with a couple of hundred extra square feet of conditioned space? Maybe you can use it as storage without fear of heat damage or mildew. How about additional living space?

On top of the extra usable space, you’ll also get an improvement in your home’s air quality! Fiberglass insulation is not an air barrier, so everywhere there is a can light or other intrusion between your attic and living space, you’re venting that hot, humid air from your attic into your home.

THE OPTIONS

There are two options for attic insulation installation with spray foam

1...

The first option is roof on the deck/rafters

Attic Rafters / Roof Deck Spray Foam – The first option is installing spray foam on the roof deck/rafters, completely sealing the attic from the outside, converting your vented attic space to a climate-controlled space. On top of creating a perfect seal between the inside and outside of the home, there are also additional benefits foam has to offer. The average home’s ductwork is estimated to leak approximately 25% and most homes have a large majority of the ductwork located in the attic space. Rather than wasting the air that your system produces you will then be using it to cool/heat the inside of the attic space.

This process will require the removal of all fiberglass batt insulation between the ceiling and attic space. You will also need to remove attic vents and fans so the space can be completely sealed off from the outside air. the fiberglass removal is needed for air circulation.

2...

The second option is on the attic floor

Attic Floor Spray Foam – The Second option is removing the current insulation from the attic floor and installing spray foam in its place. One of the biggest flaws with conventional attic insulation is that it is not an air barrier. In all areas where there are penetrations in the ceiling between the living area and the attic space, you are losing air/heat. These areas may include can lights, ceiling fans, and more. Spray foam creates an air-tight barrier that eliminates any air exchange where it is applied. This option is not ideal and we rarely recommend this to customers.

This process requires less insulation due to the flat surface as opposed to the roof surface. There are downsides to this strategy which may include potential risk of nail pops in ceiling sheetrock. You also are not going to be able to take advantage of additional conditioned space as you would insulating the roof deck.

OPEN CELL VS CLOSED

In most cases open cell or closed cell will work great in your attic but there are differences!

When considering between open cell and closed cell insulation for your attic space, the primary consideration has to do with vapor or water. Due to the cells, both foams act much differently when introduced to liquid. Closed-cell insulation is a vapor barrier and is waterproof. This leads to the question… what if my roof leaks? Open-cell will reveal a roof leak far quicker than closed-cell as it will act like a sponge. Closed-cell will not soak any water, and the water would not immediately enter the structure. We’ve had the experience of discussing with many professionals who have studied green building strategies. The general consensus is that neither option is wrong, but there are inherent benefits of having a vapor barrier between the inside and outside of the home. If you have a 30-year-old roof we recommend replacing that before either foam is installed. Our spray foam company services Bluffton, Hilton Head Island, Savannah GA, and the surrounding areas.

WHY SPRAY FOAM IS SUPERIOR

There are so many reasons spray foam insulation is the best attic insulation!

Vented attics are inefficient – Vented attics work great on paper but in application, they function poorly when compared to conditioned attic spaces. Most homes have ductwork in the attic space. Considering your vented attic will most likely be over 100 degrees when the sun is out that leads to major inefficiencies. Studies show that an average of 20-30% of your conditioned air is lost through the ductwork in your attic. In a conditioned attic your insulation is on the floor under your ductwork which means you’re basically wasting that conditioned air.

There are additional concerns to consider with vented attics such as around can lights and areas where there are holes in the sheetrock for the air to escape and no insulation in that area. On top of inefficiencies, you also have bugs and animals to consider. It’s not uncommon for squirrels or other animals to burrow in your attic! They have been known to sneak in through attic vents and turn your home into theirs!

Spray foam is the more efficient solution – Spray foam fixes all of the major vulnerabilities of batt insulation. While offering a completely airtight seal it also provides a superior insulation value. We generally recommend insulating the roof deck in an attic space but both the roof deck or the floor is superior to traditional insulation! Another huge benefit not many people discuss is the reduction in noise. We have had several customers who live near the airport or a busy roadway say that spray foam has saved them from selling their home!
