What are Glass Wool Building Blankets?
Glass wool building blankets are insulation materials made from fine, stable glass fibers bonded with thermosetting resin. They are rot-proof and free from shot due to their mineral composition.
What are the standard specifications of glass wool blankets?
Length: 10m and 20m rollsWidth: 1.2mThickness: 25mm and 50mmDensity options: 16 kg/m³, 24 kg/m³, and 48 kg/m³
What applications are glass wool building blankets used for?
They are commonly applied in:Building facades and external walls insulationHVAC system insulationRoof insulationFloor insulationAcoustic insulation for sound absorption
What are the main benefits of using glass wool building blankets?
Excellent thermal insulation to reduce heat transferFire resistance due to mineral-based compositionSound absorption properties for improved acousticsWater repellency to resist moisture damageEco-friendly with certifications like LEED and EPD supporting sustainability
What standards and certifications do glass wool blankets meet?
They comply with international ASTM and ISO standards and hold certifications such as LEED (Leadership in Energy and Environmental Design) and EPD (Environmental Product Declaration), ensuring high quality and sustainability.
Are glass wool blankets safe for fire-prone areas?
Yes, glass wool is inherently fire resistant, helping to improve building fire safety by reducing flame spread and heat release.
How does the density of glass wool affect its performance?
Higher density blankets (e.g., 48 kg/m³) provide better thermal resistance and acoustic absorption, while lower densities (16 kg/m³) are lighter and often used where weight savings are important.
Can glass wool blankets resist moisture?
Yes, they have water-repellent properties that prevent moisture absorption, maintaining insulation efficiency and preventing mold growth.
How are glass wool blankets installed?
They are typically cut to size and placed between framing components such as wall studs, roof rafters, or HVAC ducts, ensuring snug fit to prevent gaps and optimize insulation performance.
Are glass wool blankets environmentally friendly?
Yes, their mineral composition and certifications like LEED and EPD signify that they have a reduced environmental impact and contribute to sustainable building practices.
