It’s easy to overlook preparing your home for winter – but it can cost you in high energy bills, equipment malfunctions, home pest issues and more.

If you are looking for a reprieve in your energy bills, don’t expect one this year. In mid October, the Energy Information Administration predicted natural gas users will see a 22% climb in their heating bills this year over the 2015-2016 heating season. If you’ve been thinking of improving your home’s energy efficiency, now is the time. Here are steps to take today to get your home ready for winter.

  • Seal Air Leaks
    Air sealing is one of the least expensive and most effective ways to reduce energy loss and keep energy bills lower during winter. A leaky home can waste approximately 10 to 15 percent of a home’s heating dollars. Air leaks are found around doors and windows, penetration points in the attics (can lights, chimney chases, etc.).
  • Check and Upgrade Your Attic Insulation
    Many of today’s homes are under insulated when compared to today’s building codes. After sealing air leaks, adding a layer of blown-in fiberglass insulation to your attic space can further reduce your energy bills and help keep your home comfortable.
  • Seal and Insulate your Crawl Space
    Crawl spaces can cause a variety of headaches for homeowners. Because they crawl spaces have direct contact with the earth, they become damp. This is a great breeding ground for mold and mildew, and provides an ideal living space for pests.
  • Check Your Heating System
    Now is the time to schedule your routine inspection of your home’s heating system. By confirming it’s in good working order, you’ll know it’s working as efficiently as possible – and you’ll help avoid a mid-winter break down.
    And don’t forget to change your air filter! Changing it often throughout the year can help your system run more efficiently – and help reduce dust in your home.
  • Change your Light Bulbs
    Take a quick inventory of the bulbs throughout your home. Upgrading to LED bulbs can reduce your energy bills, especially during winter’s shorter days and lights are on more than any other time of year. The investment in LED bulbs will pay off quickly!

Although energy efficiency is important all year, colder temps and the prospect of an uncomfortable home makes energy efficiency a priority for many homeowners. As fall temps move in and you are thinking about the energy efficiency of your home, check out these five areas of your home for any necessary upgrades.

  1. INSULATION
    Proper insulation levels can keep you warm and reduce your energy bills. Attics are one of the biggest culprits when it comes to winter energy loss, so prep yours for winter by upgrading your insulation now. And don’t forget about air sealing your attic! Air sealing your attic is an important energy upgrade.
  2. WINDOWS AND DOORS
    Sealing around windows and door frames can help prevent heat from escaping. Sealing around windows and doors is a very inexpensive project and easy to do!    
  3. HVAC SYSTEM
    Your HVAC system works all winter. When your heating system is properly maintained, it will run more efficiently, last longer, and have fewer problems. Servicing your system now will help make it through any unexpected cold snap.
  4. THE ROOF
    Make sure your roof is in good shape. Inspect for missing and/or loose shingles. Addressing this spots now will help keep winter weather out of your home.
  5. CEILING FANS
    This is so easy – and so many homeowners forget to do this! Change the direction of your ceiling fan to create an upward draft. This redistributes warm air from the ceiling back down into your living area (tip: before you do this, dust the blades).

Just these few areas of your home can increase your home’s comfort and decrease your energy bills. Ready to get started at the top of the list by upgrading your insulation? Contact us today for a free insulation estimate.




With any project, time is money. This statement is even truer when it comes to a commercial construction project. With the scale of a commercial project, each decision becomes even more important – including choosing the right insulation contractor.

Looking to hire a commercial insulator for your next project? Here are a few things to help ensure you’re making the right choice:
  • Check their experience. Commercial insulation is a specialty. It’s important to know the contractor has experience in commercial insulation. They should confidently answer questions about fire ratings, codes, etc.
  • Up to date on new technology. A savvy commercial insulation contractor will recommend new technologies for your project that can help improve performance, aesthetics and more. A professional commercial insulation contractor will be up to date on developments in their industry, and be able to recommend new products and install methods to make your project even better.
  • Insured and licensed. It goes without saying that an insulation contractor should hold the proper insurance and licensing to do commercial work. If you have any doubt, ask.
  • Large installer base. Don’t wait until scheduling day to find out if your commercial insulation contractor has the bandwidth to complete your install in a timely fashion. Confirm your contractor and adequate number of installers available to handle your project when install day comes.
Delmarva Insulation has vast commercial insulation experience, is up to date on new commercial insulation technologies, is properly licensed and insured, and has the bandwidth to complete your project in a timely fashion. To get an insulation estimate on your commercial project, contact our office.
When it comes to insulating walls, most people think of fiberglass batt insulation. For years, fiberglass batt insulation was the only way to insulate walls. Today’s construction technology has many other options! One cost-effective and energy-efficient option is the blown in wall system.

The blown in wall system provides a high-efficiency energy blanket of insulation at a fraction of the cost of spray foam insulation. This system is installed in open cavities during the construction or remodeling process, and can be used in residential or commercial buildings. The blown in wall system gives homes a seamless, thermally efficient blanket of insulation that completely fills any void in the wall cavity.

Here’s how it works:
  • Fabric mesh is installed across the open wall cavity. It is tacked to each stud in the wall assembly.
  • Loose-fill fiberglass insulation is blown behind the fabric mesh. It is installed at a density that fills all voids in the wall cavity.
  • The penetrations in the mesh are sealed to hold the product in place.

There are many benefits to installing the blown in wall system in your next project. The blown in wall system offers:
  • Higher R-values than traditional fiberglass batt insulation, saving on heating and cooling expenses.
  • Reduced air infiltration. National laboratory tests have shown a 68% reduction in air infiltration when installing a blown in wall system over fiberglass batt insulation.
    • TAKE ENERGY EFFICIENCY ONE STEP FURTHER! Air seal each wall cavity prior to installing a blown in wall system to further increase efficiency!
  • Excellent sound control. Because loose fill fiberglass insulation completely fills the wall cavity, noise transfer is reduced.
  • Does not settle. Because the insulation is dense packed, there’s no chance of it setting and affecting r-value.

Summer Energy Efficiency - Delmarva Insulation
Are you trying hard to enjoy summer – but sweating profusely over how much you're spending on air conditioning? Saving money on your energy bills doesn’t have to be difficult. In fact, there are a few simple things you can do today to improve the energy efficiency and comfort of your home.

Try some of these:
  1. USE THE GRILL. On the warmest days of summer, keep your kitchen and home cool by using an outdoor grill for your meals instead of the stove or oven. Not only will you reduce strain on your indoor HVAC system, you can turn any day into a backyard party!
  2. SWITCH ON THE CEILING FANS. Ceiling fans better circulate the cool air already blowing inside and the slight breeze keeps you cool too. Plus, using fans actually allows you to raise the temperature setting on your thermostat four degrees. This can help lower your electricity bills without sacrificing overall comfort. Bonus tip! Switch on your bathroom fans — they pull heat and humidity from your home which also improves comfort.
  3. SEAL AIR LEAKS. Low-cost caulk can be used to seal cracks, openings and other heat penetration points in your home. Air sealing keeps warm air out and conditioned air (air you’ve already paid to cool) inside your home. Need help or have a bigger job than you can handle?
  4. MAINTAIN YOUR HVAC SYSTEM. Having your air conditioner serviced annually can help keep it running efficiently (and help prevent those  mid-summer break downs). Check and replace your furnace filter regularly (which also helps keep your home clean), and don’t forget about your programmable thermostat!
  5. Setting your programmable thermostat to a higher setting when you are not at home can save an estimated ten percent on your energy bills annually.
  6. SEAL DUCTS. Air loss through ducts can lead to high utility costs. Leaky ducts keep conditioned air from getting to desired rooms in your home, and they force your HVAC system to work harder. Leaky ducts account for nearly 30 percent of an HVAC system's energy consumption! Sealing those ducts can go a long way toward lowering your electricity bills.

Building Science Basics - Delmarva Insulation
Since insulation’s beginning, it was installed with the purpose of creating a thermal barrier around a building — and keeping those inside safe, comfortable, and protected from the elements. Little did we know building science would come on the scene and change our industry in a big way. And it’s here to stay.

There is a lot to know about building science — we’ve taken the time to break it down for you.

Much of building science focuses on air flow. Improper air flow can have severe effects on the health and safety of the people in the building. It can also cause mold growth, spread pollutants  and more. Controlling air flow increases the efficiency of a building, reduces stress on mechanicals and controls indoor air quality.

There are a few key conditions that affect air flow (courtesy ENERGYSTAR.gov):
  • Controlled versus uncontrolled airflow
    • Controlled air flow is generated by a mechanical device and is designed to help ventilate a building and/or distribute conditioned air throughout a building. Ventilation systems, fans and heating and cooling systems are typical sources of controlled air flow.
    • Uncontrolled air flow is unintended air flow into, out of, or within a building. This can be caused either by wind, warm air rising in the building, uncontrolled fans and leaks in an air handling system.
  • Air pressure from wind, heat, fans and duct systems
    • Pressure differences across holes, boundaries, and barriers within a building are caused by one of four forces:
      • Wind blowing against a building can cause large pressure differences between one side of the building and the other.
      • Heat and the buoyancy of hot air affects air pressure. Heat naturally attempts to rise to the top of a building (called stack pressure or stack effect. The amount of pressure depends on the temperature difference between the inside and outside of the building, as well as the height of the building.
      • Fans (particularly exhaust fans and HVAC air handlers) can contribute to pressures changes in several different ways. Leakage in the building envelope or the ducting, or an imbalance in the supply and return ducts can cause these fans to have a drastic effect.
      • Duct systems that leak to the outside of the building on both the supply and return sides of the system can cause infiltration rates to increase by as much as 300%.
  • Holes and pathways
    • Uncontrolled air flow (infiltration) into a building is a result of holes in the building’s shell. By reducing the number of holes in the building, and you reduce the amount of uncontrolled air flow. Buildings have two kinds of holes: designed holes and undesigned holes.
      • Undesigned holes in the home are found in the attic, walls, and floors. Any of these holes that connect to the outdoors should be adequately blocked, caulked, gasketed, or otherwise adequately sealed
      • Designed holes include any hole or system that is designed to have air passing through it in a specific direction. Examples of such holes include flues and combustion vents, chimneys, make-up fans, exhaust fans, dryer vents, cooktop fans, ventilation systems, central vacuums, windows and doors, and fresh air inlets/outlets.
All of these things are incredibly important conditions to consider when improving the energy efficiency of a home or business. The way air moves through a building matters — and it ultimately determines how comfortable (and healthy) you are where you live as well as how much it will cost you for that comfort over the lifetime of your home.
