Thermafiber | Thermafiber Insulation

Explore the exceptional, multifaceted world of Thermafiber insulation solutions, expertly designed and developed by the renowned Owens Corning. Specializing in providing advanced thermal and acoustic insulation, Thermafiber products not only secure your spaces against extreme temperatures but also assure you of robust protection against fire and unwanted noise.

What is Thermafiber Insulation?

Thermafiber® is a high-performance mineral wool insulation made by Owens Corning, designed to provide industry-leading fire protection, sound control, and thermal insulation. Engineered from natural and recycled materials, it is non-combustible and can withstand extreme temperatures of up to 2,000°F, making it ideal for commercial, industrial, and residential applications. It’s widely used in perimeter fire containment, curtain walls, and other fire-rated assemblies.

Fire and Sound Guard Plus Series

Owens Corning’s Thermafiber Fire and Sound Guard Plus series distinctly curates the insulation experience according to the thermal resistance (R-value) requirements. With a versatile array extending from R10 to R30, this series diligently caters to diverse insulative demands while encapsulating sound-absorbing and fire-resistant properties.

• Higher R-Values (R30, R24, R23): Best suited for regions experiencing more severe weather conditions or for applications demanding maximal thermal retention and energy efficiency.
• Moderate to Low R-Values (R21, R15, R13, R10): For scenarios requiring moderate insulation, like in milder climates or internal partitions, choosing a product with a lower R-value can be both cost-effective and energy-efficient.

Unwavering Protection

In each variant, the meticulous blend of fire-resistance and sound-dampening technologies guarantees not only thermal comfort but also a serene, undisturbed atmosphere within your spaces, while adding a layer of safety against potential fire hazards.

Sound Attenuation Fire Blankets (SAFB)

Dive into the world of Thermafiber Sound Attenuation Fire Blankets, meticulously crafted to handle the dual role of sound management and fire protection without interfering with the aesthetics of the space. SAFBs, available in all sizes, provide an ideal solution for robust fire protection while effectively managing acoustical performances in various construction assemblies.

Thermafiber UltraBatt Series

Navigating through the Thermafiber UltraBatt series, one encounters a potent blend of thermal, acoustic, and fire resistance. Available in an array of R-values (R-30, R-24, R-23, R-15, and R-10), this line assures you of a comprehensive shield against climatic extremities, disruptive noise, and fire perils.

• Optimal Energy Efficiency: The high-density mineral wool composition ensures a proficient thermal barrier, safeguarding against heat loss and ingress, while substantially curtailing energy expenditure.
• All-encompassing Safety and Tranquility: Simultaneously, the series ensures an acoustically serene environment and imparts steadfast fire resilience, substantiating its multifaceted applicative prowess.

Considerations for Selecting The Right Thermafiber

• Climate Adaptation: Ascertain the climatic conditions of the area to accurately choose an R-value conducive to optimal thermal efficiency and energy conservation.
• Space Utilization: Account for the specific usage of the space. For eg, a media room may necessitate enhanced acoustical and thermal control provided by higher R-value products.
• Fire Safety: In areas more prone to fire hazards, prioritizing products that emphasize fire resistance, such as SAFBs or high R-value variants, would be imperative.
• Budgeting: Evaluate your budget against the long-term benefits of each product, considering the balance between initial investment and future energy savings.

Benefits of Thermafiber Insulation

• Exceptional Fire Resistance – Helps slow the spread of flames in critical fire scenarios.
• Superior Acoustic Performance – Reduces noise transmission between walls and floors.
• High Thermal Efficiency – Improves energy performance and comfort by reducing heat loss/gain.
• Sustainable & Eco-Friendly – Contains up to 70% recycled content and supports LEED® credits.
• Moisture & Mold Resistant – Will not absorb moisture or support mold growth.
• Durable & Non-Corrosive – Maintains structural integrity over time and is safe for all construction materials.

Applications of Thermafiber

Thermafiber insulation is versatile and trusted across multiple sectors:

• Commercial Buildings – For perimeter fire containment, curtain wall systems, and acoustic control.
• Residential Homes – Between floors and walls for soundproofing and thermal regulation.
• Industrial Facilities – HVAC systems, mechanical rooms, and high-temperature zones.
• Partition Walls & Ceilings – Ideal for multi-family units and schools to control sound and improve safety.
• Rainscreen Systems – With RainBarrier products offering breathable, water-repellent insulation.

Installation Tips

• Measure & Cut Precisely – Use a sharp insulation knife to cut batts or boards to fit snugly in cavities.
• Wear Protective Gear – Always use gloves, safety goggles, and a dust mask when handling mineral wool.
• Friction Fit – For most cavity applications, Thermafiber products are friction-fit—no need for adhesives or fasteners unless specified.
• Use Mechanical Fasteners – For exterior wall applications or vertical installation, use approved mechanical fixings.
• Seal Penetrations – Fill gaps around pipes, ducts, and wires to ensure full fire and sound performance.
• Follow Manufacturer Guidelines – Refer to Owens Corning’s datasheets for specific installation best practices per product.
