FAQ — Benefits & Performance

Performance+ Earthwool 1000 Pipe Insulation can be used where pipe temperatures range from 0°F and 1000° F (-18°C to 538°C).

Fiberglass batts are manufactured in many R‑values bwetween R-8 to R-29 to accomodate needs by region and structure. For example. low‑density batts provide about R‑11 in 3½‑inch walls, while high‑density batts offer R‑15 in the same cavity. For wood construction, options range from R‑11 to R‑49. Batts intended for attics generally go from R‑30 to R‑60. Be sure to use the R‑value required by your code and climate.

Yes. Fiberglass insulation helps reduce noise by absorbing sound and limiting how much travels through walls, ceilings, and floors. Knauf fiberglass insulation products include sound performance ratings that show how much sound they absorb. Adding insulation can make rooms quieter and more comfortable. However, insulation alone does not make a space completely soundproof as it works together with other materials to reduce sound transmission.

According to the EPA's Energy Star program [https://www.energystar.gov/saveathome/seal_insulate/why-seal-and-insulate], air sealing and insulation can reduce heating and cooling costs by around 15% and total energy bills by 11%. Fiberglass insulation slows heat transfer, helping HVAC systems operate more efficiently and lowering utility costs. Combining insulation with duct sealing maximizes savings.

Yes. Adding Knauf fiberglass insulation to warehouse roofs, walls and ducts reduces heat gain and loss. Fiberglass’s low thermal conductivity and wide range of R‑values help maintain stable indoor temperatures, decrease HVAC loads and lower energy costs.

Many contractors prefer formaldehyde‑free products because they reduce odors and improve indoor air quality. Knauf’s ECOSE technology uses a bio‑based binder and is GREENGUARD Gold certified, simplifying code compliance and appealing to health‑conscious contractors and clients.

Knauf fiberglass insulation resists heat transfer by trapping air within its fine glass fibers, creating a barrier that slows the movement of heat. Its low thermal conductivity helps maintain stable temperatures and reduce energy loss. Knauf’s rigid fiberglass boards and pipe insulation are designed to perform in operating temperatures up to 850°F (454°C), helping protect mechanical systems, reduce surface temperatures, and improve energy efficiency in both hot and chilled water applications.

Potentially. Proper installation of fiberglass insulation can reduce heating and cooling costs by about 15% (according to ENERGY STAR). Knauf Performance+ fiberglass insulation slows heat transfer, helping you’re home maintain its indoor temperature which helps your HVAC system run less.
