MicroFiber Glass Wool Insulation PLN Model Naked Roll Type

MicroRoof

Micro Roof glass wool insulation is designed for roofing applications to prevent heat from the roof entering factory buildings. Factory metal sheet roofs reach maximum temperatures of 70°C during lunch breaks, which transfers heat down to the building, resulting in extremely hot working conditions.

Installing roof insulation reduces the temperature transferred from the roof, minimizing heat exposure for workers in the building. In air-conditioned warehouses, installing thermal insulation helps reduce air conditioning workload due to decreased heat transfer and enables longer retention of cool air inside.

Thermal Conductivity

For thermal insulation applications, the most important consideration is the thermal conductivity value (K-value) of the insulation. Thermal conductivity indicates how well insulation can transfer heat. Higher thermal conductivity allows more heat to pass through. Therefore, high thermal conductivity means poor insulation, as we want to prevent heat transfer. Thermal conductivity values closer to 0 indicate better thermal insulation.

MicroFiber glass wool insulation has been tested for thermal conductivity at ASTM (American Society for Testing and Materials) according to ASTM C518 testing standards to determine the material’s thermal conductivity value.

Moisture Absorption

Moisture absorption of roof insulation is extremely important because roofs may develop holes after extended use due to material wear or roof leaks that cause rainwater to drip onto the insulation. If the insulation material absorbs water, it becomes heavier and water evaporation becomes more difficult.

However, MicroFiber glass wool insulation has been tested for water absorption according to ASTM C411 standards. Test results show water absorption of < 1%, which is very low. When we test by dropping water onto MicroFiber glass wool insulation, water droplets do not penetrate the insulation material but form beads on the surface and evaporate naturally.

Mold Resistance

Roof thermal insulation is installed under roofs where inspection is quite difficult. If mold or damage occurs, insulation should not promote growth of microorganisms like mold or fungi that could affect indoor air quality. MicroFiber glass wool insulation is a product that does not promote mold growth and is not a food source for microorganisms, so there is no concern about damage from mold or fungi. It can be used safely with buildings.

Surface Burning Characteristic

According to the 2006 International Building Code (IBC), wall and ceiling surface materials inside buildings must be classified for surface flame spread according to ASTM E84 standards, with additions by NFPA (National Fire Protection Agency) according to NFPA 101 Life Safety Code standards requiring classification of wall and ceiling surface materials inside buildings as Class A, Class B, Class C tested according to NFPA 255, ASTM E84, or UL 723.

Testing yields two values: Flame-Spread Index (FSI) and Smoke Development Index (SDI), and materials are classified according to these values.

Surface Fire Classification Table According to ASTM E84

	Flame-Spread Index (FSI)	Smoke Development Index (SDI)
Class 1 or Class A	0 – 25	450 Maximum
Class 2 or Class B	26 – 75	450 Maximum
Class 3 or Class C	76 – 200	450 Maximum

According to the ASTM E84 surface fire classification table, MicroFiber glass wool insulation is classified as Class 1 or Class A with Flame-Spread Index < 25 and Smoke Development Index < 50.

Installation Methods

1.) Installing insulation in rafter spaces (with wire mesh attached between rafters)

Install insulation along rafter spaces with Wire Mesh or Chicken Wire installed between or under rafters to support the insulation. Can be installed on roofs under new construction.

2.) Installing insulation in rafter spaces (with wire mesh attached on rafters)

Install insulation along rafter spaces with Wire Mesh or Chicken Wire installed on rafters to support the insulation. Can be installed on roofs under new construction.

3.) Installing insulation in rafter spaces (wire tie method)

Install insulation along rafter spaces with wires tied to rafters at approximately 30 cm intervals to support the insulation. Can be installed on both new construction and completed roofs.

4.) Installing insulation across rafters (with wire mesh attached on rafters)

Install insulation across rafter spaces with Wire Mesh or Chicken Wire installed on rafters to support the insulation. Can be installed conveniently and quickly on roofs under new construction.

5.) Installing insulation across rafters (without wire mesh support)

Install insulation across rafters without using Wire Mesh or Chicken Wire on rafters to support insulation. Suitable for roofs with rafter spacing not exceeding 1.5 meters. Can be installed conveniently and quickly on new construction roofs.

6.) Installing insulation by attachment under floor (Concrete Slab)

Attach insulation to concrete slab using spindle pins or anchors spaced approximately 20-30 cm apart, and use wire wrapped around anchor heads extending from insulation in diagonal patterns. Anchor drilling must not impact building structure. Can be installed on both new construction and completed buildings.
