What Does Insulation Do?

​Before considering insulation installation in your home or business in Raleigh, North Carolina, you should understand what insulation does.  Insulation is a layer of material fit between inner and outer parts of walls, ceilings, and floors. Insulation’s ability to prevent heat movement has an industry measurement called R-value or R-factor. Whether wall insulation, crawl space insulation, or attic insulation, the layer of material limits heat transfer.

​Insulation installation in a Raleigh, North Carolina structure prevents healthier conditioned air from escaping and prevents unconditioned unhealthy air from getting into a living space in your Raleigh, North Carolina home, or workspaces in your business. Insulation installation reduces heat loss and improves air quality which means lower energy and healthcare bills.

​Blown insulation

Some insulation installation contractors in Raleigh, North Carolina specialize in blowing cellulose, rock wool, or fiberglass insulation with fiber blowing and vacuuming machinery. These machines can be electric or powered by gas or diesel.

Batts or Rolled Insulation

Most insulation contractors in Raleigh, NC, can add batts of fiberglass or rock wool insulation, especially in open attic spaces and new construction. Additional rolled insulation can be added over old insulation in many cases to increase energy efficiency.

​​Spray Foam Insulation

Raleigh, North Carolina spray foam insulation installation specialists use machines called reactors to install spray foam insulation. Two liquid chemicals are loaded into the reactors, and the two mix together as the installer sprays them are on home surfaces.

Spray foam insulation works well for attic insulation. The two chemicals react with each other, causing a foam that forms a waterproof seal wherever it’s sprayed. The foam takes about 24 hours to finish off-gassing (chemical reaction stops, everything is dry, and it is safe to be in the structure.)

​DIY Insulation Installation

• ​Fiberglass or Rock Wool Batts or Rolls

Installing batts of rock wool or fiberglass yourself isn’t difficult if you have access to the areas you want to insulate. You can find the insulation in local hardware or DIY store. Installing these types of insulation entails cutting the insulation to fit the spaces to be protected. 

• Blown-in Insulation Installation

While there are advantages to blown-in insulation, attic insulation is the only do-it-yourself project recommended by most experts. Hard on your back, installing blown-in attic insulation means remaining bent over for long periods of time. You need to rent an attic blower for between $100 and $200 per day. Some insulation manufacturers let you use the machine for free if you buy enough of their insulation. Enlist a helper for this kind of project. Other than for attic insulation, hire professional insulation contractors for blowing in any insulation.

• Spray Foam Insulation Installation

There are kits available in any DIY store for installing spray foam insulation yourself. The kit will include safety equipment and the sprayer or reactor with chemicals preloaded.  Read all the instructions thoroughly because you must do the insulation installation under the right atmospheric conditions (temperature and humidity).

​Be sure to spray the foam evenly. If you fail to do so, you may have to remove all the foam and start over.

There are a lot of reasons to get a professional energy audit. Besides doing a visual, room-by-room inspection, trained home energy auditors use equipment like blower doors and infrared cameras to find out where your home is losing heated or cooled air. You can do a visual inspection for yourself.

What to look for yourself

• Voids -look for places that don't have insulation. Gaps can be caused by improperly installed insulation around things like light fixtures and fuse boxes. Voids in insulation allow heat transfer by convection and radiation. Experts estimate that a 4% void in fiberglass batt insulation can lead to as much as a 50% reduction to efficiency.
• Compression - Most insulation types (other than spray foam insulation) break down or compress over time. Compressed insulation has fewer air pockets that contribute to insulation R-Value (the industry measurement of insulation effectiveness).
• Air movement - if air has regularly passed through insulation through open doors; for example, dirt deposits in the air pockets within the insulation, and you may need new insulation. The dirt interferes with insulation effectiveness because it can reduce the prevention of heat loss through convection. Air flowing through dirty insulation can also pass the dirt, mold, and dust particles into your living space.
• Moisture - If you have had a leak and attic insulation (other than spray foam insulation) gets wet, the effectiveness of the insulation is compromised, and mold growth may occur. You should contact an attic insulation installer for inspection and advice.

​Installation Risks 

Although not all professionals agree on what insulation installation cause health dangers, they do advise some cautions.
​
Fiberglass insulation can irritate skin, eyes, and lungs. In addition to wearing protective gear while installing fiberglass insulation, your family should wear a mask and skin protection when they are in areas in your home with exposed fiberglass insulation.  

Rock wool insulation, also a spun fiber, can sometimes cause similar irritation problems. 

Cellulose insulation installation causes dust to fly and can lead to a cough during and even after installation. Professional insulation installers often add a small amount of water to blown-in cellulose to lessen the problem. As air flows through, dust and allergens get trapped in the insulation. You must keep cellulose insulation dry to prevent mold from growing.  

During spray foam insulation installation and off-gassing, people exposed to spray foam chemicals vapors or aerosols risk developing asthma, sensitization, other breathing problems. Without proper protection equipment, exposure can also cause eye and skin irritation. Off-gassing takes 24 hours.
