Internal Wall Insulation

Insulating the internal walls utilising a lightweight partition system is a great space saver as the insulation is installed between the two skins of the construction of the wall. This type of internal wall insulation application provides excellent thermal efficiency, whilst also contributing to acoustic performance. Fabufill polyester insulation products will deliver multiple benefits including thermal and sound performance for both new and refurbished internal wall and partition applications.


Platinum Fibre’s, Fabufill polyester internal wall insulation solutions provides a thermally efficient insulation solution for internal partitions. The thickness of the internal wall insulation is generally restricted to the depth of the lightweight partition system, as the internal wall insulation is laid between two skins of the wall and within the depth of the lightweight structure.

Should additional thermal or acoustic performance be required then additional or thicker layers can be installed into the partition wall but the structural zone will need to be increased accordingly.

Fabufill polyester internal wall insulation is easy to install into an intrenal wall or parttion construction, as this range of SABS approved polyester insulation is non-allergenic, non-irritant and resilient insulation does not support the spread of flame, (Class B/B1/2 fire rating).

Please contact our technical service department for advice regarding the correct installation practices to achieve continuity of insulation at the wall/roof junction.
