The attic usually comes to mind first when considering home insulation. Since airflow in structures moves upward, it naturally pulls conditioned indoor air up through the attic and out of the home. Help keep conditioned air from escaping and keep your home at a comfortable temperature by making your attic energy efficient.

We have rated three popular insulation methods to help you choose the best option for your home:

GOOD: Blown-in Fiberglass
Blown-in fiberglass insulation added to an attic is a fast and easy way to increase R-value and is a cost-effective option. This creates a complete thermal barrier in your attic to help keep heated (or cooled) air inside your home.

BETTER: Blown-in Fiberglass with Air Sealing
Insulation and sealing air leaks significantly improves energy efficiency. After sealing penetration points around the attic floor, a layer of blown-in fiberglass insulation is installed. This process adds R-value and helps keep conditioned air from escaping your home.

BEST: Spray Foam Insulation
Spray foam insulation provides the best energy protection. When spray foam is applied along the roofline, it seals any air leaks and creates a thermal barrier along the ceiling of your attic. Spray foam is installed in one simple step and provides optimal energy benefits. If your home has existing fiberglass or cellulose insulation, spray foam insulation can be installed after removal of existing insulation.

Installing or adding insulation in your attic is one of the most cost-effective ways to reduce your energy bills. Uncertain about which insulation method is the right one for your new home or have questions about these three insulation options? We can help! Contact our office today!

Air sealing is the process of reducing the amount of air that leaks in and out of your home. It is an important step to reduce energy costs, reduce drafts and cold spots, help keep out pests and allergens, and increase the overall air quality in your home.

Air leakage occurs when outside air enters and conditioned air escapes your home through cracks and openings. For years, it was believed that air leaks created proper home ventilation. Today’s building science proves this isn’t the case. Uncontrolled air leaks can cause too much or too little air to enter or leave your home. Either situation can result in poor indoor air quality.

Although air sealing is a very important part of home energy efficiency, it doesn’t eliminate the need for proper insulation. Foam insulation is a perfect solution to both insulate and seal air leaks.

Foam insulation expands when applied and completely fills a cavity. The product is applied as a liquid and expands to 100 times its volume. This means that the product fills cracks and crevices in a cavity, and expands to seal these gaps.  Your home is insulated and air sealed with one application!

Hurricane Harvey
Hurricane Harvey was the strongest storm to make landfall in the Texas Coastal Bend area since Hurricane Carla in September 1961. The flooding resulting from Harvey's flooding is one of the worst weather disasters in U.S. history. It’s estimated the storm damage will amount to billions of dollars.

Even though Hurricane Harvey is off the front page of daily news, there’s no doubt the impact of this storm is far from over. The real heavy lifting of recovery and reconstruction is underway, and will continue for quite some time.

With many connections to the Houston area, the founders of Delmarva Spray Foam and its affiliated companies have been moved to assist. To this end, Delmarva Spray Foam along with Delmarva Insulation, DeVere Insulation, DeVere Insulation Home Performance, Foam InSEALators, Liberty Insulation, Southland Insulators and The Fifth Fuel have donated $28,000 to help with recovery efforts.

Bob and Carolyn DeVere along with Jerry and Nancy Palmer have selected two Texas charities to receive these funds – Samaritan’s Purse and Tomball Emergency Assistance Ministries. Each organization received $14,000 to aid in their mission of helping local families recover from this tragedy.

We are proud to support our local communities and support others during times of tragedy. If you are moved, we encourage you to donate to one of these Houston-based organizations to help with Hurricane Harvey recovery efforts.

Spray foam in poultry house
Delmarva Spray Foam and Delmarva Insulation were contracted to install sidewall spray foam insulation in three poultry houses.

The customer was experiencing issues with three 50’ x 550’ poultry houses. The structures were below standard static pressure, a result of air leaking around plywood and fiberglass insulation in the sidewalls of the structures. Additionally, the block foundations were sweating which created moisture issues inside the buildings.

Delmarva Spray Foam applied two pounds of agricultural spray foam to each structure. To prevent chickens from pecking foam from the walls, custom hybrid foam was installed to the lower 18 inches of the walls over the agricultural foam.

This hybrid foam is a custom blend designed in partnership with our spray foam manufacturer for this specific application to protect the agricultural foam and the birds, providing years of value and performance. To further help protect the birds and the structures each foam product contains beetle agents to help prevent the bugs from eating either product.

Spray foam insulation is a great product for agricultural use. Contact our office to learn more.



Spray foam insulation installed in a home
Delmarva Spray Foam and Delmarva Insulation were contracted by McGregor Custom Homes to install spray foam in a new home in Rehoboth Beach Yacht and Country Club.

Throughout the building process, the buyer was focused on energy efficiency and comfort. With this home’s location off Rehoboth Bay, the buyer was concerned about the impact of bay winds on interior climate, noise and energy efficiency.

As part of the home’s energy efficiency, the buyer installed a geothermal system for heating and cooling. He wanted a high-performance insulation system to match. In addition, we wanted to be sure his family was comfortable and their home furnishings and collectibles were kept in optimal condition.

Spray foam insulation was installed throughout the 8,000-square-foot home. Installing spray foam insulation sealed all exterior air leaks to make the home airtight on the day of application. Fully sealing the shell of the home helped reduce exterior noise bleed despite the high wind exposure.

Residential spray foam in vaulted ceiling
Spray foam insulation is an ideal product for new home construction, adding a level of energy efficiency and protection from outside elements not found with other insulation products. Foam insulation can be installed on any size project and in both existing homes and new homes. Contact our office to learn more.

Save money with an energy audit.
A home energy audit is done to determine methods for reducing energy use, saving money on utility bills, and improving overall comfort in a home. Some of the same methods used by professionals can be duplicated in your own home analysis. Here are some tips on what to look for and how to make any necessary corrections:

  1. Find Air Leaks
    One of the most cost effective changes you can make to conserve energy in your home is sealing air leaks. Common areas to check for leaks are window frames, door frames, and electrical outlets (these are very easy to feel on a cool, windy day). To do a thorough job, be sure to also check recessed can lights, the attic access door, rim joists in the basement, the chimney flue, and wherever wires or pipes enter your home. In most cases some caulk or weather stripping should take care of leaks. For can lights and chimney flues consult a professional for assistance to properly and safely seal these areas.
  2. Check Your Windows
    Check for gaps around your windows, an area where air commonly escapes. There are several ways to do this: shine a flashlight around the edges at night or use a smoke stick (when lit the smoke will drift toward leaks). Another trick: put a piece of paper in the window and then close and lock it – if you can pull the paper out without it tearing that window isn’t creating a tight seal. After leaks are located, seal them with caulk or weather stripping according to manufacturer’s instructions (weather stripping works better for larger gaps).
  3. Look in the Attic
    Inadequate insulation in your attic is a common culprit for heat loss. Standards for attic insulation may have changed since your home was built. Consider adding insulation to your attic for increased energy savings – and don’t forget about sealing air leaks!  ENERGY STAR® estimates that adding insulation and sealing air leaks (which can be done in just one step with spray foam insulation) can save homeowners as much as 10% on their annual energy bills. If you’re looking for insulation help you’ve come to right place – we’re the experts! Contact us for a free estimate.
  4. Unplug it
    Reduce “standby power” in your home. Standby power is power used by electronic devices that are plugged in, but not in use. Even though these devices are not is use, they are still draining energy (ENERGY STAR® estimates 5-10 percent of residential energy use can be blamed on standby power.) The solution is simple. Unplug it. Or, if that is too inconvenient for TVs or hard-to-reach outlets, use a power strip with an on/off switch.

Have questions on what to do after you find a problem? We can help! Call us today to discuss what you found and for a free estimate. In the meantime, check out this great resource for your own DIY energy audit from our friends at Energy Star.
