FSK Glass Wool Felt Duct Wrap Insulation - 10-48 kg/m³ Density, 25-150 mm Thickness, Non-Combustible Thermal Blanket
FSK Glass Wool Felt is a high-performance fiberglass blanket insulation specifically designed for duct wrap applications in HVAC systems. This flexible thermal insulation material features aluminum foil facing for enhanced vapor barrier properties.
GLASSWOOL BLANKET INSULATION FOR DUCT WRAP is a highly efficient, resilient, and easy-to-handle flexible blanket insulation composed of fine, stable, and uniformly textured inorganic glass fibers bonded together by a non-water soluble, fire-retardant thermosetting resin. The material can be laminated with various facing materials including aluminum foil (FSK), fiberglass cloth, and other specific vapor barrier facings to meet specific application requirements.
Designed for use in commercial, institutional, industrial, and residential construction as thermal and acoustical insulation for heating, air conditioning, and dual temperature ducts and air handling equipment. This product effectively prevents condensation when properly applied to air conditioning ductwork.
- Prevents condensation on air conditioning ductwork
- Brightens building interiors through high light reflectance
- Reduces interior lighting costs
- Provides effective vapor barrier protection
- Controls condensation and dripping moisture
