For new home insulation applications your best choice is still Rockwool insulation
Why Use Rockwool for your new Home or remodel?
Superior Thermal Permance and R-Value Rockwool insulation will save you more money due to its High R-value. Rockwool has an R-value of 4 per inch.
Fills up all spaces, cracks, removes air infiltration The Rockwool insulation can be blown into all stud spaces including irregular and hidden spaces. The rockwool will conform to the wall itself preventing any air infiltration.
Rockwool Spray-in Insulation
Rockwool Spray insulation is a green product designed to be blown into new construction walls and floors.
- Higher R- value: R-16 in 4 inch stud space R-38 in attic (11-12 inches)
- No Settling
- Fireproof: Non combustible, made at 3,000 degrees Fahrenheit
- Will not absorb moisture
- Will not support fungus growth: Passed ASTM E 1338 Fungus resistant test
- Will not house insects or varmints: Inedible and abrasive qualities deter unwelcome guests
- Superior sound reduction: Higher density insulation provides the best noise reduction
- Recycled steel slag
- Inorganic with no chemical additives
- Completely green product
- High density

Sound Proof Insulation Demonstration
|COMPOSITION||Old newspaper and other scrap paper products. Organic materal||Silica sand and recycled glass material. Inorganic material||Recycled steel slag, inorganic material||Because of its organic nature, cellulose is naturally subject to burning and decomposition|
|PRODUCTION PROCESS||Paper is shredded and grounded up into dust-like consistencies||Sand is melted with glass and spun into fine glass fibers||Slag is melted and spun into long mineral fibers||Due to its natural tendency to burn or decompose, cellulose is considered to be a hazardous product|
|CHEMICAL ADDITIVES||Large amounts of borax and boric acid plus other additives||Some dyes added||None||Additives often dissipate and can cause irritations|
|FIRE PROOF||Chemicals added to be fire resistance, but when ignited, the material will support combustion||Non-combustible. Will melt at approximately 1,000ºF||Non-combustible. Will not melt unless temperatures exceed 2000ºF||Typical house fires reach 1,000-1,400ºF. Additives that make celluose fire resistant often dissipate over time, leaving the material readily combustible|
|SETTLING||Some tests indicate 20%-30% settling over time||No significant settling when properly installed||No significant settling||Cellulose is naturally subject to settling. Some tests indicate settle factors of 30% with similar reductions in insulation at 25%-30% over settled density bag level|
|MOISTURE ABSORPTION||Organic fibers will readily adborb large amounts of moisture. Emits fire retardant chemicals while drying||Inorganic fibers will not absorb moisture||Inorganic fibers will not absorb moisture||Insulation is not effective when wet. Cellulose radily absorbs moisture; even normal condensation can permanently damage it|
|SOUND REDUCTION||Fair||Poor||Great||Sound reduction is generally related to density. Higher denisty gibes better sound reduction. Rockwool insulation is most dense.|
|MOLD/FUNGUS||Supports growth||Does not support growth||Does not support growth||Mold and fungus can make the resident sick as well as degrade and erode the structure of the building|
|R-VALUE||Around 3 per inch||Around 2.5 per inch||Around 4 per inch||High R-value corresponds with high fuel and electric savings|
