Due to the special surface structure of the foamed polystyrene, the TFPearls are water-repellent and open to diffusion. In the small cavity structures that arise in the insulation layer due to the spherical shape of the 3-5 mm TFPearls, both water as well as water vapour can be easily transported away. This guarantees an insulation layer that is always dry and a dry inner wall even if the outer shell is wet, for example because of driving rain. Since the shape of the TFPearls is stable, they retain their insulating properties for a long time and constantly as well.

You can insulate completely dust-free with TFPearls. The blown-in TFPearls fill the cavities in the walling perfectly and there is no waste. Insulation projects done later in old buildings can be handled quickly and economically and above all easily.
TFPearls are very environmentally friendly since they are free of CFCs and HCFCs. The completely filled cavities in the intermediate wall provide a noticeably improved room climate and also provide protection against pest and rodent infestations.
TFPearls can be processed with any conventional blow-in machine.
