The Versatile Solution

Fiberglass Insulation for Energy Savings, Fire Safety, and Noise Reduction

When it comes to insulating your home, the choices can feel overwhelming. Between balancing energy efficiency, cost and environmental impact, it’s easy to get lost in the options. Two of the most popular choices—fiberglass and spray foam insulation—each have their merits, but fiberglass stands out as a versatile, cost-effective, and eco-friendly solution. Whether you’re building a new home or upgrading your current one, fiberglass insulation offers a winning combination of affordability, performance, and sustainability that’s hard to beat. Knauf® products not only feature certifications like GREENGUARD and GREENGUARD Gold, but most recently added Asthma & Allergy Friendly® Certified and the Verified Healthier Air™ Verification, ensuring these certified products support healthier indoor environments—it’s a choice that benefits both your family and the planet.

Benefits of Fiberglass Insulation

By choosing fiberglass insulation, contractors and applicators can deliver durable, energy-efficient, and cost-effective solutions that meet the needs of their clients while ensuring ease of installation and long-term performance.

Energy Efficiency

Fiberglass insulation is highly effective at reducing heat transfer, helping to maintain consistent indoor temperatures. This contributes to energy efficiency, leading to lower heating and cooling costs for building owners.

Fire Resistance

Unfaced and loose-fill fiberglass insulation are non-combustible and Class A-rated for surface burning characteristics.

Durability and Moisture Resistance

Fiberglass insulation resists moisture, mold, and mildew, ensuring long-term performance. This durability makes it a low-maintenance option for contractors.

Cost-Effectiveness

Fiberglass is one of the most affordable insulation materials available, offering excellent performance at a lower cost compared to alternatives like spray foam or mineral wool.

Ease of Installation

Fiberglass insulation is available in various forms, such as batts, rolls, and loose-fill, making it easy to install in different applications. This reduces labor time and costs for contractors.

Sound / Noise Reduction

In addition to thermal insulation performance, fiberglass also provides acoustical benefits, reducing noise transmission between rooms or from external sources.

Sustainability

Many fiberglass insulation products are made from recycled glass, aligning with sustainability goals. Additionally, its energy-saving properties contribute to reducing the carbon footprint of buildings. Knauf’s insulation products utilize a minimum of 55% recycled glass.

Versatility

Fiberglass insulation can be used in walls, ceilings, attics, floors, HVAC and plumbing systems, making it a versatile solution for residential, commercial, and industrial projects.

Fiberglass insulation remains a versatile option

Knauf Performance+® fiberglass insulation meets the needs of a wide range of applications. It is made with a formaldehyde-free, bio-based binder and contains no added color.

GREENGUARD CERTIFIED

GREENGUARD certification ensures that fiberglass insulation meets strict standards for low emissions of volatile organic compounds (VOCs). This makes it a safe choice for indoor environments, as it minimizes the release of potentially harmful chemicals. GREENGUARD Gold certification takes this a step further by adhering to even more stringent criteria, making it suitable for use in sensitive environments such as schools, healthcare facilities, and homes with children or individuals with respiratory sensitivities.

ASTHMA & ALLERGY FRIENDLY®

Asthma & Allergy Friendly® Certification from the Asthma and Allergy Foundation of America (AAFA) and Allergy Standards Limited (ASL), and the Verified Healthier Air™ Verification from Airmid Health Group are awarded after extensive third-party scientific testing of a product’s ability to reduce allergen exposure and limit pollutants in the indoor environment.
