IS 14214:1995 is the Indian Standard (BIS) for glass wool thermal insulation materials. This standard specifies the requirements, testing methods, and sampling for glass wool thermal insulation materials. It covers loose wool, mattresses (quilts), and resin-bonded slabs used for thermal and acoustic insulation in buildings and industrial applications, defining key properties like thermal conductivity, density, and fire safety.
Specifies requirements for glass wool thermal insulating materials.

| Parameter | IS Value | International | Source |
|---|---|---|---|
| Thermal Conductivity (λ) at 24 kg/m³ density | ≤ 0.040 W/m.K (at 50°C mean temp) | Typically declared as ~0.035 - 0.040 W/m.K (at 10°C mean temp); the standard sets the framework for declaration, not a fixed value. | EN 13162:2012+A1:2015 |
| Fire Performance | Non-combustible (as per IS 3144) | Class A1 (non-combustible) for unfaced products (as per EN 13501-1) | EN 13162:2012+A1:2015 |
| Density Tolerance (for Boards/Mattresses) | ± 15% of nominal density | For boards, stated as -15% with no upper tolerance limit specified. Performance is key. | ASTM C612-14(2021) |
| Shot Content (Non-fibrous material) | ≤ 12% by mass (for 24 kg/m³ density group) | ≤ 25 % by mass (for all block/board types) | ASTM C612-14(2021) |
| Water Absorption (by volume) | ≤ 5.0 % (after 24h immersion) | < 0.2% (for water-repellent treated products) | ASTM C665-17 |
| Length/Width Tolerance | Length: -1%, Width: -0.5% | ±1.5 % for Length, ±1.0 % for Width (for blankets) | ASTM C665-17 |
