Open Cell vs. Closed Cell Foam Insulation: Making the Right Choice for Your Home and Businesses in New Orleans

Spray Foam Inspections New Orleans - Star Spray Foam

If you’re in need of insulation for residential or commercial applications in New Orleans, you’ve come to the right place.

As you’re likely aware, insulation comes in many types, each with its own unique qualities and use cases.

A few common types include fiberglass, polyurethane, spray foams, and cellulose.

How does a home or business owner decide which insulation best suits their needs?

It’s easy! Ask the experts. At Star Spray Foam Insulation, we want to help you make the best choices for all your insulation needs. We offer eco-friendly materials and high-quality services at affordable rates, and open and closed cell spray foam insulation to fit virtually any situation, need, or budget.

Polyurethane Spray Foam Insulation

One of the most popular choices among designers and architects today, spray foam insulation continues to beat our traditional options like fiberglass and SIPs. It’s more versatile, quite literally more flexible, and frankly, it just does the job better.

Don’t let the name scare you— spray foam is safer than materials like fiberglass. Mixed on-site and sprayed precisely, the foam will then expand to fill nooks and crannies. In the end, you have a more efficient and safe material saving you energy (and money).

However, the decision-making doesn’t stop there! Polyurethane Spray Foam Insulation can be further broken down into categories based on things like density, moisture barrier, vapor barrier, and R-value.

Two rather common types that come up in discussions are closed cell and open cell insulation in New Orleans. So, what’s the difference?

While open-cell becomes sponge-like, allowing the passage of moisture, closed-cell spray foam cures to a hard, smooth surface mass. In other words, nothing gets past closed-cell spray foam. Which works best?

Honestly, it depends on what you need your insulation to accomplish.

Open vs. Closed Cell Foam Insulation

Like every job has the best tool to be used, so too does every property need certain insulation styles. Open cell insulation in New Orleans also offers twice the noise reduction when compared to closed cells. Open cell is also an effective air barrier. The advantages of Open-Cell Insulation include: Fewer resources used.

Open cell foam is full of cells that aren’t completely encapsulated. In other words, the cells are deliberately left open. This makes the foam a softer, more flexible material. Closed cell foam is made up of cells that are, as the name suggests, completely closed.

Open Cell Spray Foam Insulation: Breathability, Great Soundproofing

New Orleans open cell insulation uses water as a blowing agent. This creates ‘bubbles’ to form as it hardens, leading to a lighter density that breathes better in vaporous atmospheres. It’s great for attic insulation and higher humidity climates.

Open cell insulation in New Orleans also offers twice the noise reduction when compared to closed cells. Open cell is also an effective air barrier.

Advantages of Open-Cell Insulation include:

  • Fewer resources used
  • Bi-directional drying
  • Accommodates long-term seasonal movement
  • Hydrophobic
  • Good air barrier
  • Enhanced sound-proofing
  • Permeability for humid climates

Closed-Cell Insulation: Strength and Tenacity

The closed-cell foam expands to fill gaps and cracks as soon as it’s applied. So what’s the difference? While open-cell becomes sponge-like, allowing the passage of moisture, closed-cell spray foam cures to a hard, smooth surface mass. In other words, nothing gets past closed-cell spray foam.

We’ll be honest: closed-cell is the more expensive choice. It has the best R-value per inch when compared to open-cell, cellulose, and fiberglass. While considered one of the best insulation materials available, you must be sure that the installation is handled by professionals. Improper installation can cause more harm than good to your property.

Scientists do warn that the installation may have a higher impact on global warming potential due to the hydrofluorocarbon (HFC) composition. Basically, closed-cell use carbon dioxide that is extremely potent when compared to open-cell; however, this material is typically installed in a thin film.

What is so great about closed-cell foam that people would risk the additional CO2? Let’s start with its strength. Closed-cell spray insulation foam can actually help strengthen walls, ceilings, and roofs. This foam is also ideal in colder climates— or in refrigeration rooms— due to its thickness and impermeability.

Closed-cell insulation also resists water degradation and moisture better than other materials.

Other advantages include:

  • Low-temperature applications
  • Racking strength
  • Impact resistance
  • Continuous insulation solutions
  • Narrow space accommodation
  • Lower vapor and less permeability
  • High tenacity and bond strength

Closed-cell insulation is also an ideal candidate for anyone in a flood-prone area.
