Looking to save money on energy bills? Check your basement

Looking to save money on energy bills? Check your basement

Basement Box Sills And Rim Joists
When thinking about insulation, the attic is the first area of a home that comes to mind. Many homeowners never think of the energy lost through their basement box sills and rim joists.

Basement box sills and rim joists are a major source of energy loss. These areas are located around the perimeter of the basement ceiling where the walls of the home meet the foundation. They are some of the thinnest points in a home’s exterior and allow outside air to easily leak into the basement.

Not only can unconditioned outside air enter the home through these areas, they are also convenient entrance points for pests. Spiders, bugs and other creatures can find their way into your home through residual penetration points around HVAC, electrical and plumbing access points next to the basement ceiling.

Spray foam is an ideal two-in-one product choice that both insulates and air seals rim joists and box sills. Be sure to hire a qualified, insured and experienced spray foam contractor to ensure your basement box sills and rim joists are properly insulated and air sealed.

Insulating and air sealing your rim joists and box sills will make your basement (and entire home) more comfortable, reduce pest infestation and help lower your energy bills. Contact us to schedule your free estimate!

The Good, Better and Best of Attic Insulation

The Good, Better and Best of Attic Insulation

Attic Home Insulation
When it comes to home insulation, the first area that comes to mind is the attic. Airflow within a building moves from ground to sky, naturally pulling conditioned indoor air up and out of a structure. Proper attic insulation helps keep conditioned air inside your home and helps keeps your home comfortable. Keeping conditioned air inside your home can also reduce wear and tear on your heating system and help keep energy bills in line.

There are three common methods used to insulate attics – blown-in fiberglass, blown-in fiberglass with air sealing and spray foam insulation. Here’s what you need to know about each.

Blown-in Fiberglass

Insulating attics with blown-in fiberglass insulation is a quick and easy way to add R-value. This is a basic method of attic insulation and a cost effective option to upgrade attics of existing homes or insulate attics in new homes.

Blown-in Fiberglass with Air Sealing

Combining blown-in fiberglass insulation with air sealing dramatically increases a home’s energy efficiency. This method helps keep conditioned air inside the home and adds R-value. In an existing home, attic insulation is removed and penetration points around the attic floor are sealed. After air sealing is complete, a fresh blanket of blown-in fiberglass insulation is installed. In a new home, penetration points around the attic floor are sealed before blown-in insulation is installed.

Spray Foam Insulation

Installing spray foam insulation in the attic of a new or existing home provides optimal energy protection. In an existing home, insulation is removed from the attic and spray foam is installed along the roofline. In a new home, spray foam insulation is installed along the roofline as part of the construction process.

Proper attic insulation combined with air sealing is one of the most cost effective ways to save money on monthly energy bills. Wondering if your home could benefit from additional attic insulation? Ready to discuss insulation for your new home project? Contact our office today!

Four Fall Projects that Save Money and Energy

Four Fall Projects that Save Money and Energy

Smart Thermostat
Homeowners seem to have a never-ending list of projects. Landscaping, painting and other cosmetic projects are often a high priority. Before investing more time and additional resources this fall into these types of projects, consider some energy saving improvements. Here are four projects that can help save money on energy bills and increase your home’s comfort this fall – and all year!

Add a Smart Thermostat
A smart thermostat can help decrease overall home energy use, including heating and cooling costs. Smart thermostats adjust the temperature of your home based on your family’s schedule and your lifestyle. According to Nest, a smart thermostat brand, the investment can pay for itself over time based on an average 30% reduction in energy bills.

Air Seal
A home loses most of its energy (including heated air) through the attic. A home has a natural updraft that draws inside air up and out of the home through small penetration points in the attic floor. Sealing air leaks around the building envelope – including in the attic – helps keep conditioned air in the home and energy bills low.

Upgrade Attic Insulation
Once attic air leaks are sealed, adding a blanket of insulation will provide additional energy savings. Think of air sealing as tucking the blanket around you and insulation as the blanket. Insulation provides a thermal layer to helps keep R-value (energy) in a home.

Tune Up Your Furnace
A furnace works more efficiently and will have a longer life when it’s regularly serviced. Having your furnace serviced before heating season is in full swing can help prevent system problems during the peak heating season.

Windows or Insulation? Read This First!

Windows or Insulation? Read This First!

Insulation Or Windows
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

Home Energy Audit
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.
