What is Open Cell Spray Foam Insulation (Low Density)?

Open cell spray foam insulation is spray foam that is applied as a low density thermal insulation on walls & ceilings. Spray foam is one of the most common types of insulation and air sealing material that is applied in different home locations which require thermal insulation. Open cell spray foam insulation has an open cell structure which does not allow air leakage. It is soft in nature due to the open cells in the spray foam which is why moisture build up is quite possible. This spray foam technique is less costly as compared to closed-cell spray foam insulation and expands more when applied to a surface. It creates a tight building envelope which ensures you get the best energy flow and an improved energy efficiency.

How Does Open Cell Spray Foam Insulation Work?

Spray foam insulation is made by reacting isocyanate and polyol resin. When the spray foam is applied to the desired site, it expands on contact with any surface to create a foam that seals away gaps and holes creating the perfect air, moisture, and vapor barrier. Open cell spray foam can be used to seal any kind of cavities in walls, furniture, windows, attics, small gaps, and cracks present in structures.

Spray foam insulation limits air ventilation throughout the space where it is used. Open cell spray foam when applied to a surface ceases air, energy influx and efflux eventually improving the overall energy efficiency. As a result, it limits the intrusion of pollutants, vermin, and allergens and makes the space more comfortable for people. 

Is Open Cell Spray Foam Low-Density?

Low-density spray foam is mostly used to fill interior wall cavities and areas where ventilation is not provided. Its R-value starts at 3.6 per inch. The higher the R-value, the greater is the thermal insulation properties of the SPF solution. After the curing process, the spray foam produces a low-density cell structure which prevents air leakage.

Low-density spray foam provides heat insulation and seals air flow when applied in cracks, joints, and seams filling up the cavities. It can also absorb sound waves and provide excellent noise cancellation due to its open cell structure. Most open cell foam has a density of about 0.5 pounds per cubic foot.

Why Should You Get Low-Density Spray Foam Insulation?

Low-density spray foam is an open cell spray foam that can be used to fill, isolate and reduce vibration in larger cavities. It can also deaden sound. The low-density polyurethane foam is dispensed using special dispensing tools for accurate and precise applications. Due to its excellent adhesion properties, low-density spray foam can help improve indoor air quality and lower energy bills by maintaining a comfortable temperature inside. Spray foams, sealants, and adhesives contain no formaldehyde, CFCs, HCFs, and VOCs.

Is open cell spray foam insulation suitable for areas with harsh weather?

No, it is not suitable for areas with harsh weather because it is less dense than closed cell spray foam and has an R-value of 3 per inch. Therefore, it can be used in small areas with moderate temperatures to be maintained.

Areas Where Open Cell Spray Foam Insulation Can Be Applied?

Low-density spray foam insulation is commonly used for interior applications. It can be applied in wall cavities, unvented attics, basement walls, ducts, roof decks, ceilings, and crawl spaces.

Is open cell spray foam insulation an energy-efficient insulation option?

Open cell spray foam insulation helps lower energy bills by decreasing the usage of HVAC units. This is because it regulates the temperature inside homes so that they remain cool in summer and warm in winter. As a result, heating and cooling systems do not have to be running continuously and you can remain energy-efficient.

Air Seal Insulation Systems is a reliable insulation company that offers cost-effective and professional open cell spray foam insulation to thermally insulate and soundproof your residential and commercial spaces.

Yes, open cell spray foam insulation is low-density insulation because it has an open cell structure which means it is less than closed cell spray foam insulation. The low density can be used for thermal insulation and sound absorption in small inaccessible areas.

The main difference is in the cell structure. Closed cell spray foam has a high-density cell structure in which the cells are tightly bound together whereas in open cell spray foam there is more flexibility due to the open structure of the cells. Closed cell spray foam has an R-value of 7 per inch whereas open cell spray foam has an R-value of 3 per inch.

Open cell spray foam insulation creates a tight air barrier that limits moisture from entering your home. This in turn reduces mold and mildew growth that need moisture to survive. With open cell spray foam, you can improve the overall air quality of your home.

Open cell spray foam insulation seals all cracks and crevices in your walls, ceilings, and roofs. As a result, there is no risk of allergens, pollen, dust, or contaminants entering the premises. This improves air quality so you and your family can live in a fresh and clean environment.

Even if you’re one of the trained experts, finding an air leak is not always an easy job. It requires a keen eye & professional expertise to see where the draftiness is happening. You can always go for finding out the best sources of where the chilly air is coming into your premises. It can be openings in your windows, doors, patched walls or other similar locations. These entry points can be better treated with insulation types with better R-values.

By covering these entry points, you can eventually get rid of the draftiness problem.
