FAQ

When it comes to closed-cell spray foam insulation, thickness matters—not just for energy efficiency, but also for air sealing and moisture protection.

While some data sheets say 1 inch of closed-cell foam can act as a vapor retarder and give you a decent R-value (around R-7), that doesn’t mean it’s fully doing the job of a moisture or air barrier.

Here’s what third-party product testing and evaluation reports say:

• 1.5 to 2 inches of closed-cell spray foam is typically needed to qualify as a Class II vapor retarder

• 2 inches or more is for efficient moisture control and full performance

Just applying a thin layer—or “flashing”—doesn’t mean your building is sealed from air or moisture. For closed-cell foam to truly work as intended, it needs the right thickness.

Simply adding insulation isn’t going to address any air leakage. A properly air-sealed attic floor, top plates and rim joist prevent this unwanted airflow, making your insulation far more effective. Together, air sealing and insulation will help your home maintain the desired temperature for longer periods — cutting energy costs and improving indoor health and comfort.

Air sealing is the process of closing off any gaps, cracks, seams, or holes in your home’s exterior shell — often called the “building envelope.” Whether you’re trying to keep out winter’s chill or summer’s heat, sealing these openings is the first line of defense in protecting your home from the elements.

Closed Cell Spray foam is about 4 times more dense than the Open Cell Spray Foam.  On top of the benefits that spray Foam insulation provides Closed Cell Spray Foam is also a vapor, moisture, and rodent barrier. Open Cell is not suitable for every installation due to its inability to stop moisture and the R-value that matches most conventional fiberglass insulation solutions. Due to it’s density, Closed Cell Spry Foam also carries a lot of “Wracking Strength” that promotes and reinforces the structural stability of the whole structure that is insulation with Closed Cell.

Loose-fill insulation should not be done as a DIY project for many reasons; here are a few:

You shouldn’t install loose fill by hand; the material has to be conditioned in a specially designed BLOWER machine that breaks and agitates the insulation.

1. The material from the Blower machine must pass a corrugated hose, which continues the material conditioning process.
2. If material is not properly conditioned and installed, you lose on: R-value, yield, and energy. You can also inadvertently introduce a major moisture issue to your home.

A profound NO. There are no ingredients in the Spray Foam material composition that would promote any type of organic growth, such as mold. It also does not have any type of ingredients that would promote higher levels of moisture or attract moisture in any way. Poor installation, on the other hand, can greatly contribute to high moisture levels that aid in mold growth and wood rot.

Determining factors include age, structural damage, moisture problems, and the type of insulation used. Signs like mold, pest infestations, or energy inefficiency can also indicate a need for removal. To understand your home’s insulation needs contact Attis Insulation today!

Spray foam and fiberglass blown insulation are two common types of insulation materials used in buildings, and they have several key differences:

1. Material Composition:
   • Spray Foam: Spray foam insulation is typically made from two types of chemicals that are mixed and sprayed onto surfaces. These chemicals react and expand to create a foam that fills gaps and seals spaces.
   • Fiberglass Blown Insulation: Fiberglass blown insulation is made from tiny glass fibers that are blown or installed into wall cavities, attics, or other spaces using special equipment.
2. Installation Method:
   • Spray Foam: Spray foam insulation is applied as a liquid that expands and hardens into a solid foam. It can be sprayed directly onto surfaces and is often used for air sealing, filling gaps, and insulating irregularly shaped spaces.
   • Fiberglass Blown Insulation: Fiberglass blown insulation is installed by blowing loose fibers into cavities using specialized equipment. It is commonly used for insulating attics and wall cavities.
3. R-Value:
   • Spray Foam: Closed-cell spray foam typically has a higher R-value per inch compared to open-cell spray foam. This makes it more effective at insulating and providing a higher level of thermal resistance.
   • Fiberglass Blown Insulation: The R-value of fiberglass blown insulation depends on the thickness and density of the material, but it generally has a lower R-value per inch compared to closed-cell spray foam.
4. Air Sealing:
   • Spray Foam: Spray foam provides an effective air seal when properly applied. It can help prevent drafts and air leakage, which can improve energy efficiency.
   • Fiberglass Blown Insulation: Fiberglass blown insulation may not provide as tight of an air seal on its own, but it can still be effective when combined with other air sealing measures.
5. Moisture Resistance:
   • Spray Foam: Closed-cell spray foam is relatively impermeable to moisture and can act as a moisture barrier. Open-cell spray foam is less resistant to moisture and may require additional moisture control measures.
   • Fiberglass Blown Insulation: Fiberglass insulation is not a moisture barrier and can retain moisture if it becomes wet, which may require replacement if it gets saturated.
6. Cost:
   • Spray Foam: Spray foam insulation is generally more expensive upfront compared to fiberglass blown insulation due to the cost of materials and installation.
   • Fiberglass Blown Insulation: Fiberglass blown insulation is often more cost-effective in terms of material and installation costs.

The choice between spray foam and fiberglass blown insulation depends on various factors, including your budget, insulation goals, and the specific requirements of your building. It’s often a good idea to consult with a professional insulation contractor to determine the best insulation solution for your project. Additionally, building codes and regulations in your area may also influence your choice of insulation material.

Blown-in insulation offers several advantages over other types of insulation. It is more versatile and can be used in various areas of a home or building, including walls, attics, and floors. It is also easy to install and can be done quickly with the right equipment. In addition, blown-in insulation has better soundproofing properties, which can help reduce noise levels in a building. As for the types of blown-in insulation, there are several options, including cellulose, fiberglass, and mineral wool. Each of these has its own unique properties, such as fire resistance, moisture control, and thermal performance, so it is important to research and choose the one that best fits your specific needs.

Blown-in insulation is installed by using a blowing machine to shoot the insulation material into the desired area. The types of blown-in insulation include cellulose, fiberglass, and mineral wool. Cellulose insulation is made from recycled paper and is the most common type used for blown-in insulation. Fiberglass insulation is made from glass fibers and is also commonly used for blown-in installation.

Spray foam insulation can last for up to 80 years if properly installed and maintained. Contact Attis today to go over the details of your next project to find the right solution for you!

Spray foam insulation is generally regarded as more effective than other types of insulation, such as fiberglass or cellulose. This is due to its ability to form an airtight barrier.

Not all spray foam is the same. Open cell spray foam is comparable to the fiberglass in it’s R-Value, while closed cell spray foam almost doubles the R-value per inch of thickness. However, the cost of closed cell spray foam insulation is typically higher than other types, so it may not be the best choice for every situation. It is important to consider factors such as budget and specific insulation needs when making a decision.

Spray foam insulation provides various benefits such as improved energy efficiency, reduced air and moisture infiltration, and enhanced noise reduction. When compared to other types of insulation installations, spray foam insulation may have higher upfront costs but can lead to significant cost savings in the long run due to its superior insulation properties. According to a study by the Spray Polyurethane Foam Alliance, homeowners can save up to 40% on their monthly energy bills by switching to spray foam insulation. Additionally, spray foam insulation can increase the resale value of a home and provide a better return on investment than other forms of insulation.

While there are several types of blown-in insulation, the best products are made of recycled paper materials, such as newspapers or cardboard. Other materials are made of glass or waste minerals.
