TermoZ 8 U

The universal ETICS screw fixing with Delta-Seal coated steel screw

The fischer TermoZ 8 U is ideal for fixing pressure-resistant insulation up to 220 mm thick in concrete, solid and perforated brick and aerated concrete securely with European Technical Assessment. The screw fixing comprises a grey plug sleeve with a preshaped disc, a locking ball and a Delta-Seal coated screw. The TermoZ 8 U is set flush to the surface with a screwdriver with a T-30 drive. An air column is created above the head by the locking ball. This reduces heat transmission. The flexible head offsets the thermally induced tensions and prevents damage to the surface.

Product Description

  • High retention forces thanks to the screwing process and embedment depth of 70 mm.
  • High level of corrosion protection of the screw thanks to Delta-Seal coating.
  • An air gap is produced above the screw head due to the sealing ball. This reduces heat transmission losses.
  • The flexible head compensates for any heat-related tension and prevents damage.
  • Can be combined with the insulating discs DT 90, DT 110 and DT 140 for very soft insulating materials.
  • For insulating material thicknesses up to 320 mm.
