Our Attic Insulation Offerings in Long Island, NY

Insulation comes in a wide variety of material types, each offering unique advantages to suit each particular home and area. At Rocket Insulation, we offer the following insulation types for attic insulation installation and attic insulation retrofit:

  • Spray foam: Both open-cell and closed-cell spray foam insulation are newer, highly efficient forms of insulation. These insulations are applied wet and expand rapidly to fill in spaces while leaving no gaps or holes.
  • Cellulose: Loose-fill and blown-in cellulose insulation is made of primarily recycled materials and is lauded as one of the most eco-friendly insulation options on the market. Combined with an excellent product life span and superior R-value, you have a top-notch insulation material for attic spaces.
  • Fiberglass: Fiberglass rolls, batts and loose-fill are classic insulation options for attic spaces, featuring excellent insulation levels for a very reasonable price.

Should I Choose Spray Foam or Cellulose Insulation for my Long Island Attic?

When determining how to insulate an attic choosing the right material and type is extremely important. However, there’s actually not a “best” option for all cases. Most modern insulation types are high performers in terms of insulating, adding energy efficiency and being reasonably cost-effective.

This said, for Long Island homes, we often recommend higher R-value options like spray foam insulation (closed-cell in particular, for added water resistance) and blown-in cellulose insulation to protect against our weather extremes. These options are particularly effective in attic spaces that lack headroom, and they tend to have a very long overall life span to offset their slightly higher attic insulation cost.

Frequently Asked Questions About Attic Insulation

My insulation is old but looks okay — can I keep it?

The International Association of Certified Home Inspectors says most types of insulation, including loose-fill fiberglass and batts, can last 100 years or more. That said, if you own an older home, it’s worth having your attic insulation inspected by a professional who can check to ensure the underlying structure is still in good shape. Over the years, small leaks can cause cellulose and other insulation types to get moldy. Once you learn it’s still in good shape, you can most likely add more insulation on top.

We only use our attic for storing decorations. Do I still need to put drywall on top of insulation?

Most local building codes now require faced insulation to be covered with drywall to reduce the chance of its igniting during a fire. 1/2-inch drywall is generally sufficient, but you or your installer should check local building codes before installation.

Is there such a thing as too much insulation?

Yes, while rare, it’s possible to over-insulate your home to the point it can’t breathe! Insulation is designed to seal your home’s interior tightly, but if the seal is too tight because there are too many layers of insulation, moisture can get trapped between the layers. That can lead to a mold problem. Plus, all that extra insulation that isn’t making a difference can be a waste of money!

Can I just add more attic insulation over what I already have?

It depends on the type of existing insulation and its condition. Generally, you can install new insulation over old insulation unless it’s wet, as any trapped wetness can develop mold and mildew. If your home’s attic currently has cellulose insulation, you can add any other insulation over it you wish as long as it doesn’t have a vapor retarder or facing.

Can I install insulation myself?

We don’t recommend it because even simple insulation jobs need specialized tools like protective equipment. Spray foam installation, in particular, requires expertise and a professional installer ensures the job is done right!
