Thermo-Floc® Blow-In

Thermo-Floc® Blow-In is a formaldehyde-free fibreglass loose wool that can be used as wet or dry blow-in ceiling and cavity insulation.


This loose fill insulation guarantees superior thermal and acoustical performance, easy installation, environmental protection and the personal well-being of occupants post-installation. Thermo-Floc® Blow-In ceiling and cavity insulation can be bonded with a motionless, odour-free air-setting binder to seal and control the movement of fibres during the installation process. Our binder does not affect the colour or performance of the product.


• Thermal Conductivity (W/m.K of 0.04515)
• Thermal Resistance (R-value of 2.21m2.K/W) at 100mm
• Thermal Resistance (R-value of 2.55m2.K/W) at 115mm
• Thermal Resistance (R-value of 2.99m2.K/W) at 135mm
• Thermal Resistance (R-value of 3.32m2.K/W) at 150mm


The thermal performance of bulk insulation products is measured by their Thermal Resistance or R-value. The R-value is the ability of a product to resist the transfer of heat and is the most important factor when selecting thermal insulation. The higher the R-value the more effective the insulation.

To check which thickness of thermo-floc you should install to comply with the minimum R-value stipulated in SANS10400-XA refer to the Thermal specification thickness guide per climatic condition zones here.
