External Wall Insulation

Insulating the external walls utilising is an excellent method of providing 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 external wall applications.


Platinum Fibre’s, Fabufill polyester external wall insulation solutions provides a thermally efficient insulation solution for external walls. The thickness of the external wall insulation is restricted to the gap between the two skins of the external wall, as the external wall insulation is laid between two skins of the wall.

Should additional thermal or acoustic performance be required then additional or thicker layers can be installed into the external wall but the gap between the skins of the wall will need to be increased accordingly.

Fabufill polyester internal wall insulation is easy to install into an external wall 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.
