Get Started

Blown-in insulation is a great way to insulate your Lindenhurst, NY area home’s attic space. Its insulating properties result from the fluff of the shredded materials used for blown-in insulation, including fiberglass and cellulose.

Benefits of Blown-In Insulation

Blown-in insulation is often used in place of batts for a number of reasons:

  • It’s easier and faster to install than batt insulation

  • Because it’s a continuous layer with no seams, blown-in insulation provides up to 25% better efficiency than batt insulation strips

  • Blown-in insulation can be installed for different R-values (thermal resistance values) without the limits of batts

Identify & Seal Air Leaks Found with a Home Energy Audit

To maximize the effectiveness of your blown-in attic insulation, Green Homes Long Island recommends conducting a home energy audit to identify air leakage. Air sealing before adding insulation can boost your energy savings by as much as 20%. Once the gaps and cracks are identified using infrared imaging, they can be sealed with hand-applied spray foam by our insulation services team. Your attic area will now be ready for our insulation services team!

Fast, Easy Insulation Installation

Once our insulation team has prepared your attic area with meticulous air sealing, the insulation will be blown into the area. Just as we have in hundreds of homes throughout Nassau and Suffolk County, we’ll set up the equipment to blow the shreds of insulation into the attic using an oversized hose. While either fiberglass or cellulose material can be used, we prefer using recycled cellulose insulation for its environmentally friendly, plant-based properties.

What is the R-Value of Blown-In Insulation?

The R-value of blown-in insulation can vary. Blown-in fiberglass R-values can range from 3.1 to 3.4 per inch. Cellulose has a slightly higher R-value range of 3.2 to 3.7. The combination of slightly higher R-value and sustainability make cellulose our preferred material. For comparison, spray foam insulation has an R-value of about 6 to 7 per inch.
