What is Insulation, and Why Do You Need it?

Home Spray Foam Insulation Maryland
Before making insulation installation decisions, it’s important to understand what insulation does.  Insulation inhibits air movement so that the air treated by an HVAC system stays inside and the hot or cold outside air with its irritants and pollution stays out. Insulation material installed in empty spaces in a structure like between inner and outer walls, floor and basement, ceilings and attics, or attics and roofs prevent air from moving.  Insulation contractors install crawl space insulation, attic insulation, and wall insulation. An HVAC system does more than controlling the temperature; it also filters pollutants and irritants from the air. Having the best insulation like spray foam insulation in your Maryland home or office means your system doesn’t have to work so hard.

Besides preventing air movement, most insulation also provides soundproof insulation. You hear less of your neighbor’s music or local traffic noise. Spray insulation also prevents pests from entering.  Unlike other materials, spray foam is water-resistant and adds structural strength to a house or commercial building, enabling it to stand up against storms and high winds.

​
*R-Value  - Builders and insulation contractors measure the effectiveness of an insulation material by looking at its R-value or R-factor number. R stands for resistance, and a number assigned to insulation tells a contractor how well insulation resists heat movement.  R-factors or values are per inch of material, so resistance increases as the thickness does. Spray foam insulation has a higher R-factor per inch than most other insulation types.

What is Spray Foam Insulation?

Installer Spray Foam Insulation Maryland
​Spray Foam was initially used to insulate airplanes in the 1940s. The industry has continued to experiment, innovate, and improve the formulas and installation techniques and spray foam insulation is today’s most popular insulation.

Spray foam insulation for Maryland homes differs from more traditional insulations like fiberglass rolls, blown-in, or rock wool. Insulation contractors at A & J Spray Foam spray two liquid chemicals that mix and react with one another to expand into an insulating foam. The foam completely fills space, blocks moisture and sound, prevents air movement, and improves a building’s structural integrity.

Spray Foam Insulation Types

There are three spray foam insulation types, each with specific benefits.
Open-cell Spray Foam Insulation Maryland

Open-Cell Spray Foam Insulation

Open-Cell Spray Foam Insulation is less dense and softer so that it can tolerate structural expanding and contracting better when seasonal temperature changes occur.

​Open-cell costs less than the other two options, but it provides the best soundproofing insulation. A & J Spray Foam may recommend open-cell for your Maryland home to block out traffic noise.
Installed Closed-cell Spray Foam Insulation Maryland

Closed-Cell Spray Foam Insulation

Closed-Cell Spray Foam Insulation is denser and harder when it dries, enhancing structural strength and providing better water resistance. The insulation value, R-Value, is higher per inch than in open cell.

​If A & J Spray Foam installs closed cell spray foam insulation in the walls of your commercial building in Maryland, you can expect your structure to withstand mother nature's worst.
High-density Spray Foam Insulation Maryland

High-Density Spray Foam Insulation

High-Density Spray Foam Insulation takes closed-cell insulation another step. It’s denser, even more water repellant, and has the highest insulation factor per inch.

​Contractors use high-density spray foam insulation on roofs and exterior walls in commercial buildings.

Why Do We recommend Spray Foam Insulation Rather Than Other Types?

Wall Spray Foam Insulation Maryland

​1. Longer lasting

Spray foam insulation lasts indefinitely or as long as your Maryland home or commercial building lasts. Other insulation materials typically must be regularly replaced because they collapse and lose their effectiveness over time. Paper fiber or fiberglass insulation is not waterproof like spray foam, which means replacing it more often. Although spray foam insulation has a higher initial cost, because you never need to replace it, it’s the best value long term.

​2. Environmentally friendly

​When you replace insulation often in your home, you create more waste, which adds to the landfill. The waterproofing quality prevents damage from floodwaters, so spray foam insulation in a Maryland building also prevents the destruction of natural resources.

​3. Better performing

The building industry measures an insulation capability to prevent air movement in terms of R-Value or R-Factor per inch, and spray foam insulation has higher R-Values than most other materials. That means it prevents heating and cooling loss better than different types.

​4. Waterproof

​Spray foam insulation also creates an excellent water barrier, preventing leaks and helping reduce the damage if floods occur.

​5. Pest prevention

​Pests usually enter your home through all the little holes and cracks left by plumbers and electricians during construction. Spray foam insulation fills the gaps and crevices so pests can't get through.

​6. Faster to install

​Once we remove the old insulation in your Maryland home or business, A & J Spray Foam Insulation contractors can usually finish a residential installation in a single day. The foam is dry to the touch within a few minutes, and your family or employees can be safely back in your home or business after 24 hours.

​7. Fits unusual structures

It’s difficult to cut insulation like boards or rolls of fiberglass to fit small or unusually shaped spaces. One advantage of spray foam insulation in a building in Maryland is that it can fit any space. If you have attic space windows, the spray can fill around the windows. If you have hard-to-access crawl spaces, you can still insulate them. Vaulted ceilings, skylights, and other unusual structures are no problem.

​8. Increased home or business value

​Homebuyers want a well-insulated home and don't want to replace insulation in a few years. With spray foam insulation, a buyer gets a home that will never need insulation replacement. They get a house with lower utility bills, cleaner air, and more comfortable rooms. Business owners want clean air and comfortable temperatures for themselves and their employees. Whether they buy or lease a building, they want it to be well-insulated. More desirable properties are worth more.

Insulation Removal

Insulation removal must be done professionally because each insulation material has safety protocols for removal and disposal.
Removal Spray Foam Insulation Maryland
Fiberglass, for example, can release particles into the air if it's not handled carefully. These particles make breathing more difficult and are dangerous to people with breathing problems.

​Our professionals at A & J Spray Foam understand spray foam insulation removal and know Maryland and local government regulations on the disposal of each material.  If we should find asbestos, we can provide a remediation service as well.  Sometimes old insulation can stay in place, and sometimes it should be removed. It's important to hire someone who knows the difference.

Do It Yourself Spray Foam Insulation

While the process seems simple, and you can purchase kits from any DYI store, you should think twice before attempting a spray foam insulation project in your Maryland home.
Installing Spray Foam Insulation Maryland
Read some details about the problems with Installing spray foam insulation yourself.  You must mix the two chemicals in exactly the right proportions and under the right atmospheric conditions. Spraying the foam evenly takes a lot of practice, and if you get it wrong, you’ll have to remove all the foam and start again.

​You’ll need professional-grade personal protection gear to do the job safely. You will need a respirator, gloves, eye protection, and skin protection. If you think you’ll save money, check out the prices of kits, calculate how many kits you will need, and then get an estimate from A &J Spray Foam in Maryland. Savings may not be as much as you estimate.
