What Type of Attic Insulation Is Right for Your Home?

Radiant heat barriers between attic joists

Attic insulation is easy to overlook, but it plays an important role in the comfort and efficiency of your home. Choosing the right type of attic insulation can keep temperatures more comfortable year-round, lower your energy costs, and even protect your home. If you’re ready to replace your existing attic insulation, New Jersey Siding & Windows, Inc., offers an overview of the different types that are available so you can make the right choice for your home.

Attic Insulation Types

Various types of attic insulation trap and release heat in different ways, with a material’s ability to do so called its R-value. By choosing the best type for your attic, you can ensure the most comfortable, efficient home possible. Available attic insulation types include:

Blown-in Fiberglass

Blown-in fiberglass insulation is made for filling necessary spaces and comes in loose, tiny chunks. This affordable option is primarily used to fill in holes near pipes, wiring, or awkward framing. It’s also a great choice for low-ceiling attics.

We provide the eShield Perfect Attic Insulation System, a formaldehyde-free blown-in fiberglass insulation from manufacturer Johns Manville. This system brings the insulation to an R-38 value, which measures around 15 inches, to comply with the New Jersey state code. Constructed of 100% recycled fiberglass, this insulation is the only kind guaranteed to retain its original R-value.

Fiberglass Batts

Most frequently used, fiberglass batts come in rolled-up sheets held together by an adhesive vapor barrier. They are moisture-resistant and fire-resistant, so they are less susceptible to mold and mildew and can be installed on wooden structures. They are also easy to install and can cover large amounts of property.

Spray Foam

Open-cell and closed-cell spray foam expand when applied to deliver a strong seal. Waterproof, this insulation strengthens a building’s structure and offers a sound barrier. Unlike most materials that need to be replaced every ten years, spray foam can last for decades and is usually the best choice for commercial applications.

Take Advantage of Blown-In Fiberglass Insulation with New Jersey Siding & Windows, Inc.

Most attic insulation only protects against conduction and convection, neglecting radiation, which accounts for most heat loss in homes. However, the eShield Perfect Attic Insulation System features a multi-layer aluminum radiant barrier sheet that reflects 97% of all radiant heat transfer to its source: the sun. This process keeps your home from overheating in the summer, and it can be conveniently installed over existing insulation without you needing to replace or add to your fiberglass.

We also deliver an air sealing service to close openings in the attic that are attached to the living space. This service helps keep hot and cold air from going back and forth between these areas. For assurance, we refill any insulation for free if it does not remain at its original R-value.
