Fiberglass insulation and spray foam insulation are two of today’s most popular building insulation products. Fiberglass insulation has a competitive price point and spray foam insulation has air sealing benefits. Flash and batt installation brings together these two products in one application for use as new home insulation, commercial insulation and industrial insulation.

Flash and batt is also known as a hybrid insulation system. Flash and batt provides the benefit of air sealing with spray foam insulation at a lower price point than full foam. This is a great option for a contractor looking for air sealing and is mindful of a tight construction budget.

In a flash and batt system, one inch of closed cell spray foam insulation is applied. Once this is dry, a fiberglass batt is placed over the top of the foam.

Flash and batt insulation is a good insulator to consider if you are looking for the air sealing benefits of spray foam insulation at a lower price point than full spray foam.

Different types of insulation can be helpful depending on the project. Mineral wool is a great option to insulate commercial and industrial projects. What is mineral wool? Mineral wool insulation is also known as rock wool insulation or slag wool insulation. It is manufactured in batt and loose-fill forms, and can be used to insulate any area of a building. In addition to insulating commercial and industrial projects, mineral wool can be used to insulate residential homes.

Here’s a bit about what makes mineral wool insulation unique:

  • Mineral wool is manufactured from basalt, a volcanic rock, and is naturally fire retardant. This can be of particular interest in commercial and industrial construction projects.
  • Mineral wool has high thermal performance. It can withstand temperatures of over 700 degrees, making it ideal for commercial or industrial insulation applications that are exposed to extreme heat.
  • Mineral wool is naturally very moisture resistant. It retains its insulating qualities even when wet, making it a great option to insulate a space that faces moisture issues.

Comprehensive Commercial Insulation Options

Delmarva Insulation at Construction Site

Fiberglass

Fiberglass batt insulation is available in widths suited to standard spacing of wall studs, and ceiling or floor joists. Blown-in fiberglass insulation can be installed in nearly any space. It can be dense packed into closed cavities

Spray Foam Insulation

Spray foam insulation is a two-in-one product, insulating and air sealing in one step. Our commercial insulation contractors install both open cell spray foam and closed cell spray foam. To learn more about our spray foam insulation options, visit our Spray Foam page.

Spray Foam Insulation In Progress
Open cell spray foam has a density of 0.5 pounds per cubic foot. It is made up of cells of foam that are not completely closed. The cells are broken and air fills all of the "open" space inside of the material. Open cell spray foam insulation has an r-value of 3.4 to 4.5 per inch.

Closed cell spray foam has a density of 2.0 pounds per cubic foot. The cells are closed and packed tight together. They are filled with gas that helps the foam rise and expand. Closed cell foam is very dense, and therefore has greater insulating properties and can also increase building strength during high winds and storms. Closed cell spray foam insulation has an r-value of 5.4 to 7.2 per inch.

Flash and Batt

Flash and batt installation brings together two of the most popular insulators: spray foam insulation and fiberglass batt insulation. This technique is used in wall cavities in the following two-step procedure. First, one inch of closed cell spray foam insulation is applied to the target area. Once the closed cell spray foam is in place, a fiberglass batts are placed over the top of the foam. The result is an insulation solution that provides all of the benefits of air sealing with spray foam insulation at a lower price point than full foam.

Mineral Wool

Mineral wool insulation offers the R-value found in other insulation products and is a fire resistant. Made of inorganic fibers derived from basalt, a volcanic rock, these materials are naturally fire resistant. It can reduce the spread of a fire and provides valuable extra minutes to save people and property, and reduce environmental damage.

Mold in a home can cause a variety of problems for homeowners and builders. Mold can affect indoor air quality, create health issues for occupants, and be a complicated problem to fix.

In order for mold to grow it needs mold spores to be present (which are all around), moisture, and warm temperatures. While all three elements are necessary for mold to grow, moisture regulation is a significant contributor that can be managed.

While moisture in a home is impossible to avoid, there are a few simple ways to decrease the likelihood of developing mold:
  1. Seal the Building Envelope.
    Properly air sealing wall cavities helps keep moist outside air out of the home. If needed, allow drying time for the materials before closing up the wall. This is important for products such as wet spray cellulose, which introduces moisture into a wall cavity. This should include carefully monitoring humidity levels on the jobsite.
  2. Add Proper Ventilation.
    When a building is air sealed, it’s important to have a proper ventilation system. This helps move out any damp air that could contribute to mold issues in the home.
  3. Seal Basement Box Sills.
    One of the most common areas where mold growth is found is on basement rim joists and box sills. When basement box sills are insulated with fiberglass batts and not air sealed, moist outside air can infiltrate the home and mold can build up behind these batts. Insulating and sealing box sills with spray foam insulation can prevent infiltration of moist outside air.
Taking the necessary steps to prevent mold from the beginning will save headaches and money for homeowners. Concerned about mold in your home? We can help. Contact us for a free estimate.




In the fall of 2016, Delmarva Insulation was contacted by Milford High School’s Odyssey of the Mind team.  Odyssey of the Mind is a year-long academic competition where students compete to solve difficult long-term problems in unique ways.  At the time we were contacted, the team was looking to create a backdrop to resemble a stone wall. The team was in need of foam board insulation that would be gently heated and painted to look like rock.

Delmarva Insulation donated foam board to the team. After many hours of work, the student team transformed the foam board into a simulated rock wall. To make the foam look like stonework, the kids used a soldering iron to carve lines and then a heat gun to contour the foam, giving it a rock like appearance.  A few coats of black latex paint then gave the desired effect.

Their efforts paid off! In early 2017 the team participated in the World Finals. They placed 15th in the world!  Congratulations to these students and their advisors!

Did you know the majority of our exposure to air pollutants is from indoor air we breathe?

You may be surprised to learn that indoor air (in your home, office, etc.) can be two to five times more polluted than outdoor air. The U.S. Environmental Protection Agency (USEPA) estimates that the average person receives 72 percent of their chemical exposure at home. When considering the significant amount of time we spend indoors – in our homes, offices, and more – indoor air quality becomes even more important.

Indoor air pollutants come from different sources. Some indoor air pollutants are a byproduct of construction materials, home furnishings, products used to clean the home, and more. Other indoor air pollutants come from air infiltration that isn’t properly managed or controlled.

There are many ways to improve your home’s indoor air quality. Here are some tips:

Seal Air Leaks – Sealing air leaks helps create a controlled indoor environment. A qualified auditor or contractor can recommend a plan to air seal your home. Spray foam insulation can add r-value to your home and seal air leaks in one step.

Properly Ventilate – Once air leaks are sealed and there is a controlled indoor environment, the home can be properly ventilated. A mechanical ventilation system with good filtration can help remove polluted indoor air from the house.

Reduce Indoor Chemicals – Choose products that have low chemical emissions. This can include cleaning products, home furnishings that are added to the home, and more. This will help your home ventilation system work most effectively.

Summer Energy Efficiency - Delmarva Insulation
Are you ready for summer and secretly worrying about your summer energy costs? Many homeowners experience higher than necessary energy bills during summer. Saving money on energy bills and keeping your home comfortable isn't as hard as you think. 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? Contact us for a free estimate.
  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! 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.
  5. 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.
