Insulation and Crawl-Space Weatherization

The most important parts of your home or business are the things you can’t see, like the time you spend there together and the fun memories you create. While only you can create those intangibles, we’re here to help with the other things you can’t see- the things that keep you and your family comfortable.

One way that we see often neglected is your insulation and weatherization. If you’ve only taken notice of your insulation needs during times when it’s failed, you’re doing a disservice to your comfort and are most-likely wasting valuable energy and money.

Weatherization may sound intimidating, but that term simply means adding improvements to your home that save energy. This could mean sealing air leaks, improving ventilation, or adding insulation.

Doing An Energy Audit

According to the U.S. Department of Energy, these improvements provide both short and long-term energy savings. While properly insulating walls and roofs can save you money and energy over the lifetime of your house (30 years or more) taking other steps to make your HVAC systems more efficient can maximize the impact of your weatherization and insulation for 10 to 15 years. On average, the U.S. Department of Energy says the return on low-cost efficiency upgrades like these is valued at 2.2 times greater than your original cost.

The best way to determine where your home is wasting energy (and wasting valuable money) is through an energy audit. An added benefit of performing this type of preventive maintenance, especially in older homes or buildings, is that it brings attention to the often-overlooked sections of your home. This audit works as much as a safety check as much as it does an energy check.  If you don’t want to do the audit yourself, BNG is equipped to complete your audit for you and make the necessary fixes to improve your home or offices’ energy efficiency.

Heat Loss from a House

An auditor will be able to identify areas where your home is leaking the most air, and will analyze how your home’s energy systems work together, comparing that to your energy bills. An auditor will then recommend cost-effective energy enhancements, and that’s where BNG comes in. We have extensive experience in home insulation and weatherization, serving the energy needs of homeowners in the Indiana communities of Evansville, Newburgh, Boonville, and Rockport.

Blown Cellulose Insulation

Blown cellulose insulation has notable benefits over traditional fiberglass insulation. Unlike other insulation materials, blown cellulose can be applied to new homes, or retrofitted in older homes by simply creating a small hole in the top of the wall to spray the insulation into. The blown cellulose has the highest recycled content of any insulation, and takes less energy to create than any other insulation. With our focus on efficiency and eco-friendliness, using materials like cellulose that are energy efficient for your home or business and is also made from recycled material is a worthwhile investment to reduce your environmental footprint and cut cost through short and long-term energy savings. You’re helping yourself, your friends and family along with the entire planet!

All of the cellulose is treated with boric acid, which despite the intimidating name, is commonly used as an antiseptic. It also repels insects, rodents, prevents dry rot, and is fire retardant. In fact, it is the only insulation that creates a two-hour firewall, critical time to save your home during a fire.

As we mentioned earlier, blown cellulose can be applied to new homes or retroactively during an energy upgrade. That is because the insulation is blown into wall cavities. By opening up a small section of the wall near the roof, technicians can spray the insulation into the cavity if fiberglass batting isn’t in the wall cavity or can just be sprayed directly onto a new wall. If there are fiberglass batts in an attic, cellulose can be blown on top of it to create a “cap” of new insulation without removing the old batts, ensuring your home is completely sealed and protected against the cold.

Scientifically, blown cellulose is the best choice in wall cavities where you have electrical wires, plumbing, or some other types of utility features, which are present in more than half of all wall cavities in a home. This is because the blown cellulose particles can fit much closer to these utility features than is possible by cutting fiberglass batting. Air pockets left in insulation can reduce the overall efficiency of the wall, so having the best seal possible is key. Blown cellulose can even be used in places where traditional insulation is too heavy, like in sloped ceilings. The cellulose will protect, but not cause walls or roofs to sag.
