Product Description

The fischer termoz 8U 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.
  • 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.
