Cost-effective, multipurpose thermal & acoustic insulation for ceilings, roofs, walls, and ducting
Product Overview
Fiberglass wool blankets are made from fine, spun glass fibers formed into lightweight, fibrous batts with a binder. These blankets deliver efficient thermal insulation and sound absorption, making them popular across a range of building applications .
Key Features & Benefits
Non-combustible & Fire Safe: Glass wool itself is non-combustible; facing may alter performance but wool remains fire-resistant.
Thermal Insulation: Excellent insulation with R-values typically around R‑2.5 to R‑4 per inch (~25–110 mm thickness).
Acoustic Performance: Dense, fibrous structure absorbs sound—reducing noise transmission and reverberation.
Moisture & Rot Resistant: Fiberglass is hydrophobic and does not encourage mold, vermin, or decay.
Durable & Easy to Install: Lightweight and flexible, suitable for ceilings, wall cavities, and under-floor installations.
Optional Vapor Barrier Facing: Available with foil-faced or paper-faced options serving as vapor control when installed properly.
Typical Specifications
Form Factor: Rolls or blanketed batts, cut or friction-fit into studs.
Thickness Range: Typically 25 mm to 180 mm depending on thermal and acoustic needs.
Density Options: Varying densities, for example approximately 8–11 kg/m² at thicknesses of 25–100 mm for ceiling or wall insulation.
Common Applications
Residential & Commercial Ceilings/Attics: Ideal for thermal comfort and energy efficiency.
Wall Cavities & Partitions: Provides both thermal resistance and sound dampening.
HVAC Ducting: Used as lining or wrap to control heat loss and noise in duct systems.
Industrial & Commercial Projects: Especially in offices, entertainment venues, mechanical rooms where cost-effective performance is needed.
Compliance & Standards
AS/NZS 4859.1: Must comply with this for insulation materials used in NZ and Australian buildings.
ASTM C665/C764: US standards define requirements and classifications for mineral and glass wool blankets.
Health Note: Fiberglass may irritate skin or eyes during installation—proper PPE (gloves, mask) is recommended.
