Spray foam is one of a kind insulation and sealing material. It is applied on site so that it can be molded to the surface on which it’s applied. The application process creates a tight building envelope, which increases efficiency in energy use.
Spray foam insulation and insulation foam sealants are produced by mixing and resolving distinct liquid components. The liquids are extremely reactive when mixed, and applied on the spot, expanding when they come into contact to form foam that insulates and closes gaps, and may create the air as well as moisture and barriers to vapors. Spray foam is flexible and can be used to create a barrier to wall cavities and exterior walls, as well as attics, crawlspaces as well as small cracks and gaps within a home. Spray foam products are able to limit air through filtration as well as air circulation within the home which reduces the use of energy, reduces the entry of allergens and pollutants, and also makes your home more comfortable.
The different spray foam type and methods of the application provide distinct advantages. The three primary kinds of spray foam that can be utilized to provide insulation as well as other uses:
HIGH-DENSITY
3 lbs./cubic Ft. A closed-cell foam
R-Values start at 5.5 per inch*
A lot of times, they are used for exterior or roofing applications
MEDIUM-DENSITY
2 lbs./cubic Ft. A closed-cell foam
R-Values start at 5.7 per inch*
Commonly used to provide continuous insulation for internal wall cavity filling and non-vented attic insulation applications
LOW-DENSITY
0.5 lbs./cubic feet. an open-cell foam
R-Values start at 3.6 per inch*
Commonly employed for the interior wall cavity filling as well as non-ventilated attic applications
*R stands for resistance in the direction of heat flow. The greater the value of R more powerful the insulating power. Request your dealer for the fact sheet about R-value.

SPF HIGH-DENSITY ADVANTAGES
Builders typically opt for the high-density spray foam when high insulation values and strength are required. As its name suggests, this foam is denser than other kinds made of spray foam. The spray foam is often an ideal option for roofing or other types of exterior insulation due to its seamless, monolithic structure. High-density spray foam will also decrease energy bills significantly throughout the life of a roof because of it’s heat resistance properties. It also provides increased protection against air and water infiltration and enhances the structure to the extent it is applied. The bonds that spray foam form to the roof will increase the construction’s resistance toward wind uplift which helps to minimize the damage caused by high winds.
MEDIUM-DENSITY SPF ADVANTAGES
Medium-density foam comes applied as lower high-pressure 2-component spray foam. Medium-density foam provides specific benefits based on the climate as well as the kind of structure in the area it is utilized. Similar to low-density foam medium-density SPF, medium-density is typically utilized to provide continuous insulation and interior wall cavity filling and attic fill that is not vented. But, medium-density is closed-cell spray foam; it is commonly used in situations where there is a requirement for the most R-value insulation per square inch. Medium-density foam serves as air or vapor barrier, as well as a water barrier and can also help to in reducing the noise.
Medium-density foam can also offer large tensile as well as bond strength. It may also offer low vapor permanence and is generally not affected by moisture like storms driven by winds.
SPF WITH LOW-DENSITY AVANTAGES
Also known as open-cell-foam low-density spray foam is a spray-applied to provide continuous insulation and air-sealing barrier. Low-density SPF can also be referred to as 1/2 pounds foam because it weighs approximately 0.5 pounds. for every cubic foot. The open cell structure of the foam provides some flexibility to foam.
The low-density foam is applied as high or low-pressure 2-component polyurethane spray foam. Low-density spray foam is applied to walls, unventilated attics, to ceilings and ducts, and in vented crawl spaces. It is referred to for its role as an air barrier, however, it is permeable to moisture and vapor. It is frequently used to fill in cavities in walls when they are being constructed.
Due to its large cell structure, Low-density foam remains more flexible and soft following the curing process.. Its low-density spray foam offers thermal insulation and also seals airflow cracks joints, seams and joints by filling in the gaps. Additionally, the foam is able to absorb sound because of its soft texture and open cell structure.
