St Louis Spray Foam Insulation

Spray Foam Insulation is Superior

Spray foam insulation is by far the most superior insulation material on the market today. Applying spray foam in your home or building will dramatically improve the energy efficiency of the space.

Thermal Properties:

St. Louis Spray Foam Insulation Foam insulation has substantial thermal properties. Standard insulation materials such as fiberglass and cellulose have r-value’s ranging from 2.5 – 3.2 per inch installed. Spray foam carries an exceptionally high r-value of 3.9 – 7.4 per inch installed. This extremely high r-value proves that no other insulation material available today, performs as well as spray foam.

Air Sealing:

Not only does spray foam perform well as a thermal insulating product, it also works great in air sealing applications. Air sealing is a critical component of the energy efficiency within a home. Standard insulation materials such as fiberglass and cellulose can help prevent thermal energy loss within a home but, these products have zero air sealing benefits. Spray foam insulation seals around all electrical boxes, plumbing penetrations and wires. When applied properly, spray foam will expand into all cracks and voids and create an extremely tight building envelope.

Sound Proofing:

Spray foam insulation is a fantastic sound barrier. Foam absorbs sound waves and prevents them from entering unwanted locations. Typical foam sound proofing applications include: Home theaters, bathrooms, garages, bedrooms and high traffic areas.

Improved Air Quality:

Spray foam emits zero negative gasses and is 100% resistant to mold and moisture. Because spray foam is such a strong air sealant material, it prevents unwanted allergens from entering your home or building.
