Fiberglass insulation’s main component is fine glass fibers, derived from natural ingredients such as sand and recycled glass products like windows and beverage bottles. Fiberglass is the most widely used home insulator, and is also used to reduce noise transfer room to room.  

Fiberglass insulation comes in a variety of R-values, and is manufactured in batts and rolls.

Blown insulation (also called blowing wool) is designed for thermal efficiency and to reduce noise transfer and improve acoustics. Blown insulation can also be added to attics where batts have been installed to fill any spaces where the batt does not fit tightly.
Blown fiberglass insulation is ideal for use when reinsulating an existing home. By simply creating a small access point in the area to be insulated, fiberglass insulation can be blown into the cavity. Blown insulation can also be added to attics where batts have been installed to fill any spaces where the batt does not fit tightly.

We use two types of blown in insulation: OPTIMA from CertainTeed and JM Spider from Johns Manville.

OPTIMA

OPTIMA gives homes a custom-designed, seamless, thermally efficient sound-reducing blanket that completely fills any void. No other product installs better or performs better than OPTIMA.

OPTIMA fiberglass insulation is blown behind a special OPTIMA fabric, or equivalent, in new construction. It can also be used for retrofitting existing sidewalls. This product is designed for closed-cavity applications only.

System Benefits:

• Blown in dry
• No drying required-immediately ready for drywall
• Thermally efficient-fills voids for higher R-Values per inch
• Excellent sound control
• Little dust-quick clean-up
• More uniform application
• Won't settle
• GREENGUARD® Children & Schools Certified
• Formaldehyde-Free

JM SPIDER
JM Spider Custom Insulation is a spray-in fiberglass insulation system. It fills framing cavities completely, leaving no gaps or voids. This system is a combination of lightweight fiberglass and a revolutionary adhesive binder that keeps the product in place and prevents settling.

The system uses fiberglass with 25 percent recycled content and is protected against mold growth with an EPA-registered mold and mildew inhibitor. JM Spider is part of Johns Manville’s complete line of Formaldehyde-free™ fiberglass building insulation and improves indoor air quality, because it’s made without formaldehyde.
