What is Fiberglass Insulation?

Fiberglass insulation is made from recycled glass pieces that are spun to create tiny fibers that can be used to insulate most areas of your home or building, including walls, ceilings, attics, and more. It’s one of the most popular and widely used insulation products on the market today and comes in two forms: batts/rolls and loose fill. These high-quality fiberglass insulation materials offer strong thermal resistance and dependable performance in tough climates like Sioux Falls, SD, Bozeman, MT, and across North Dakota.

Batts/Rolls

The most familiar type of fiberglass, batts or rolls come in a blanket form that is ideal for unfinished walls, floors, and ceilings. These premade strips come in a variety of widths for a tight fit between wall studs, attic and floor joists, and beams. We use a variety of durable fiberglass batt insulation products from Johns Manville and Owens Corning, including Owens Corning® PINK Next Gen™ Fiberglas™ Insulation and Owens Corning® QuietZone® . This type of insulation is beneficial for wall cavity fiberglass insulation, garage insulation, and new construction insulation projects.

Loose Fill

Loose-fill fiberglass is blown into open areas using a special machine to create a protective blanket for your home or building. It’s often used to insulate attics, but can be installed in many places, including between floors and interior and exterior walls. It’s an excellent choice for hard-to-reach spaces or closed cavities that require dense packing. We install highly effective loose fill products from Johns Manville and Owens Corning, including Owens Corning® PROPINK®. This option is ideal for attic fiberglass insulation services, retrofit upgrades, and improving comfort in shops, houses, and apartments.

Benefits of Fiberglass Insulation

Cost Effective

Fiberglass’s price tag is less than that of other insulation products but just as effective. Homeowners appreciate that the cost of installing fiberglass insulation remains one of the most budget-friendly ways to reduce heating and cooling costs year-round.

Eco-friendly

Fiberglass has an environmentally friendly composition that is formaldehyde-free and created from recycled materials, making it a wise choice for energy-efficient insulation solutions.

Energy Efficient

Fiberglass provides excellent energy efficiency to help lower your bills and keep your building comfy. Pair it with air sealing for maximum performance and noticeable utility bill savings.

Absorbs Sound

Fiberglass provides excellent acoustical performance by minimizing noise transfer between rooms and from outside. This makes it an ideal product for thermal and acoustic fiberglass insulation needs.

Smaller Carbon Footprint

The efficiency of fiberglass means your HVAC unit can work less to maintain a comfy indoor temperature, saving energy and lessening your carbon footprint.

Stability

With fiberglass, you can count on a long-lasting insulation that is non-corrosive, non-combustible, resistant to moisture buildup and mold growth, and won’t settle, rot, or deteriorate with age. Its durability makes it a leading option for cold climate insulation solutions throughout North Dakota, South Dakota, and Montana.
