Windows or Insulation? Read This First!

Windows or Insulation? Read This First!

When thinking about home upgrades, many homeowners consider two projects: insulation or windows. There are many conflicting messages about which is the best investment. Before you get out your wallet, read the following so you can make the best choice for your home.

One factor in saving energy is sealing the building shell – the outermost part of your home including walls, roofline and attic. Sealing the building shell will keep conditioned air inside your home. It will keep energy costs in line and make your home more comfortable. Windows comprise a small portion of the shell of your home and won’t provide the same energy benefits as air sealing and insulating.

Another factor in saving energy and considering insulation versus windows is your home’s natural airflow. Air inside a home naturally flows from ground to sky. Your home loses 70% of its energy through the attic and roof which is far more than is lost through windows or doors.

A final factor in saving energy is R-value. R-value is a measure of the amount of heat flow a product resists. The higher the R-value, the better it reduces heat transfer. The R-value of windows can vary from about 1.5 to 2 based on the number of panes, air space between panes, etc. Upgrading attic insulation to current code results in an R-38. Add this R-value with the prior data about heat flow in a home and it’s easy to see why a fresh blanket of insulation is a great investment.

When looking at the bottom line, the choice is clear. According to Home Advisor, the average cost to upgrade windows in our area is $5,372. The same report shows the average cost to upgrade fiberglass insulation in our area (before air sealing) is $1,511.

Three Ways to Make Your Home More Efficient

Three Ways to Make Your Home More Efficient

Would you like to make your home more comfortable and efficient? Advancements in building science make it easier than ever to improve the efficiency of your home. A home energy audit can uncover specific upgrades that may benefit you.

Some upgrades that could benefit most homes in the Mid Atlantic:

Air Sealing

Air leaks in your home’s envelope can affect heating and cooling efficiency, energy bills and comfort.  Sealing air leaks is a first step to improve your home’s energy efficiency. Air sealing involves sealing any penetration points where air can escape from your home. Air leaks can exist around recessed lighting, chimneys, ductwork and windows. Sealing these air leaks helps keep conditioned air inside your home, reduces wear and tear on your HVAC system, and maintains your home’s internal temperature.


Many homes – even newer homes – aren’t adequately insulated. Older homes may have no insulation at all. Properly installed insulation in attics, walls and floors creates a thermal blanket that prevents heat transfer. This helps sustain even temperatures throughout the house. The result is a quieter, more comfortable living environment that is less costly to heat and cool.

Home Technology Upgrades

Many homeowners aren’t aware of how home technology can help maintain comfort and manage energy bills. There are many options for decreasing energy use including controlling lights at home through a mobile app and investing in smart appliances that cut down on energy use and costs.

Improving your home’s efficiency will pay off in lower energy bills and a more comfortable home all year. Have questions? Contact our office.

Southland Insulators: America's Green Insulator

Southland Insulators: America's Green Insulator

America's Green Insulator - Southland Insulators
When you think of the construction industry, what is one thing that comes to mind? If it's garbage and construction scrap, you are not alone. According to the EPA, renovation of existing structures and keeping them up to date generates over 40 percent of total construction and demolition debris. 

The amount of plastic in use is staggering. Since the 1950s over 9 billion tons of plastic have been made. In fact, one estimate indicates the amount of plastic currently in use is 30 percent of all plastic ever produced. If you think all this plastic is being recycled, think again. Only 9 percent of all plastic waste is recycled.

In 1998 our leaders instituted a recycling program - far before  "going green" was popular. The goal of the program was to dramatically reduce the waste generated through insulation projects - and we've done just that! To date, our program has sent over 1 million pounds of plastic for recycling - that's 1 million pounds of plastic kept out of landfills!

America's Green Insulator - Southland Insulators
Our extensive recycling program includes:
  • Our team bringing back all trash and scraps from jobs they install, rather than filling a dumpster at the project location. 
  • Fiberglass insulation pieces are separated from other scrap. These pieces are ground up to make blowing wool for installation in attics.
  • Cardboard is separated and compacted for recycling.
  • Through our partnership with Rewall, the plastic bags from our batt and blown-in fiberglass insulation is recycled into interior wallboard.
  • The 50-gallon steel drums from their foam division is dripped dry and crushed to six inches high and recycled as scrap steel.
  • All wood pallets received from various manufacturers are returned to Greenfiber, a cellulose insulation manufacturer, to reload their product on for future deliveries.
  • We regularly deliver loads of 5,000 to 8,000 pounds of plastic from insulation packaging to recycling centers rather than to landfills.

Why Spray Foam?

Why Spray Foam?

If you are not familiar with the benefits of spray foam insulation, we are here to help! Like other insulation products such as fiberglass insulation and cellulose insulation, spray foam insulation reduces heat transfer between spaces in a home. Spray foam insulation goes one step further by sealing air leaks to prevent conditioned air from escaping.

Why does this matter?

Air leaks exist around the building envelope – the outermost layer of the home (exterior walls, rooflines, etc.). Air leaks through penetration points that are found around recessed lights, plumbing stacks, electrical wires, attic hatches/doors, chimneys and more. Sealing air leaks keeps conditioned air inside your home. When these air leaks are sealed, conditioned air you’ve already paid for stays in your home. This results in your HVAC system working less, which keeps money in your pocket.

When installing spray foam insulation, the building cavity is insulated and air sealed in one pass. This means one installation provides a thermal barrier and seals penetration points. Air sealing can be performed in combination with other types of insulation, requiring additional labor on the project. If not applied precisely, air sealing won’t have the desired effect. With one spray foam application, you are assured air leaks are completely sealed.

Camden Washingtonian Chooses Southland Insulators

Camden Washingtonian Chooses Southland Insulators

As the Mid-Atlantic’s largest independent insulation contractor, Southland Insulators has had the pleasure of working on some of the largest construction projects in the region. We were recently honored with being contracted for the insulation work on the Camden Washingtonian condominium community. Located in Gaithersburg, Maryland, Camden Washingtonian is a project being constructed by Camden Development. Camden prides itself on developing properties that exceed market expectations – their selected insulation package is no exception.

Camden Washingtonian contains 365 condo units. Southland Insulators air sealed each unit to increase energy efficiency. After air sealing each unit, our team installed fiberglass batts in all exterior, demising and corridor walls. Our team filled the interstitial space between the floors and the ceiling with fiberglass batts to help reduce noise transfer. As a final step, spray foam insulation was applied to the loading dock and trash room ceilings.

We are proud to partner with another company that believes in going above and beyond for its customers. Visit this link to learn more about Camden Washingtonian. If you would like to work with the area’s premier insulation contractor, click here to connect with our team.

Don’t DIY Your Insulation – Why to Hire an Insulation Contractor!

Don’t DIY Your Insulation – Why to Hire an Insulation Contractor!

Many homeowners tackle their own home improvement projects. With many resources available including retail stores and online videos, homeowners may feel confident enough to take on almost any project. When it comes to installing or upgrading home insulation, it’s best to hire a professional insulation contractor.

Here are three reasons why you should hire a professional insulation contractor:

  1. Proper Installation. Without proper installation techniques, insulation will not perform efficiently. A professional insulation contractor has the experience and training to competently install insulation to maximize performance, attic venting to optimize airflow and air sealing to reduce outside air infiltration.
  2. Building Code and Building Science Knowledge. Hiring a professional insulation contractor gives you access to a wide array of knowledge and training. Professional insulation contractors stay current on local building codes, new insulation technologies and installation methods to be sure your home is correctly insulated and as energy efficient as possible.
  3. Safety. A professional insulation contractor conducts safety training for its installer team. Effective safety training reduces the risk of a workplace injury. A professional insulation contractor is trained to spot other hazards such as wiring issues, including knob and tube, installing around combustible materials and more.

Don’t let the perceived cost savings of DIY insulation cost more in the long run. Hire a professional insulation contractor and have the job done right the first time! Our office provides free estimates. Call today to schedule yours!
