Product Overview: Earthwool Insulation Glasswool Blanket with Aluminum Foil
Earthwool insulation glasswool blanket with aluminum foil (also known as Earthwool glass wool roll with aluminum foil or foil faced Earthwool insulation) represents a flexible, lightweight insulation material composed of fine glass fibers bonded with a thermosetting resin. Specifically, the Earthwool insulation technology incorporates a sustainable, plant-based ECOSE binder that contains no added formaldehyde. Consequently, one side of the blanket is laminated with reinforced aluminum foil (FSK), creating a reflective vapor barrier that enhances thermal performance and provides condensation control.
TARCO Industry produces its Earthwool insulation glasswool blanket from high-quality quartz sand, limestone, dolomite, and recycled glass cullet, containing up to 80% recycled glass content. During production, we melt these raw materials at high temperatures and fiberize them into fine filaments. Ultimately, the aluminum foil facing is bonded to one side, providing a reflective surface that reduces radiant heat transfer and protects against moisture ingress.
Key Features & Benefits of Earthwool Insulation Glasswool Blanket
Furthermore, the aluminum foil facing provides a reflective vapor barrier that significantly enhances thermal performance in roof and duct applications. Additionally, Earthwool insulation glasswool blanket with aluminum foil achieves low thermal conductivity of 0.032–0.049 W/m·K, effectively reducing heat loss and improving energy efficiency. Moreover, the FSK facing acts as a radiant heat barrier, reflecting radiant heat and providing assured condensation control when installed with sealed joints and penetrations. Consequently, the Earthwool insulation technology offers superior moisture resistance through DriTherm silicone treatment, water repellency greater than 98%, and resistance to microbial growth. Therefore, the product is soft to handle, odourless, and easy to cut, wrap, and install on irregular surfaces, reducing labor costs. In addition, Earthwool insulation glasswool blanket is compression packed to provide more product per pack, and it contains no added formaldehyde, making it safe for installers and building occupants. Furthermore, the product is non-combustible with a 50-year warranty, ensuring long-term performance and peace of mind.
