Fiberglass Insulation

The smart choice to make spaces more comfortable and energy efficient.
Why Choose Fiberglass Insulation?
It’s ideal for your next project. Fiberglass insulation is the smart choice for homes as well as commercial and industrial buildings, because it can make your living spaces and workplaces more comfortable and energy efficient.


By reducing energy usage, fiberglass insulation allows your heating and cooling systems to operate with greater efficiency, which decreases energy use, may reduce your energy bills and limits the release of greenhouse gases into the atmosphere. Fiberglass insulation helps you — and all of us — do more while consuming fewer resources. 

Fiberglass resists heat transfer in attics, ceilings, ducts, floors, piping and walls in buildings and applications of all types. That’s why it’s been widely used in construction for more than 80 years.


What’s in the insulation you choose is just as important as how well the fiberglass insulates. At Knauf Insulation, we truly believe this, which is why we eliminated traditional phenol-formaldehyde (PF) and replaced it with the world’s first bio-based fiberglass insulation binder. 

Homeowners, businesses and institutional owners all share common concerns about the sustainability of their buildings and construction materials. That’s why we manufacture fiberglass insulation with renewable materials such as sand and glass recycled from many sources, including glass bottles and other resources destined for landfills. The result? Fiberglass insulation that promotes both energy efficiency and sustainability. It can even save the amount of energy it took to make it in just hours or days.

What Makes Fiberglass Such a Good Insulator?

For Commercial and Industrial Environments

Provides reliable thermal performance against high and low temperatures and serves as protection to people who work near equipment and piping. Architects and engineers also specify fiberglass acoustic insulation when sound management is required across a range of frequencies found in manufacturing settings and in large-scale HVAC systems.

For Residential Homes

In single-family houses, homeowners and DIYers count on fiberglass to keep their residences cool in summer and warm in winter. The same holds true for professional installers, who face unique requirements across the various types of wood structures and in the metal-framed buildings they are hired to insulate. 

Working with Fiberglass Insulation Couldn’t Be Easier
Choose the insulation that delivers peak performance, is easy to handle, simple to install, cost-effective and durable over the lifetime of your project. Whether it’s called fiberglass, glass wool or glass mineral wool, insulation is made by spinning flexible glass fibers into various forms that trap air. The fiberglass disrupts and slows heat transfer and helps reduce the transmission of sound. Other attributes include:
Available in rolls, batts, boards, blankets, blowing insulation and preformed pipe.
Comes in many types and sizes to match standard building framing and piping. It's easy to fabricate and designed to fit.
