High-performance, thermally-broken connectors for concrete-to-concrete balcony applications. Particularly suitable for highly energy-efficient structures, heavily-congested or stepped floor slabs, applications where maximum corrosion protection is required and when an integral fire resistance is preferred to the installation of a separate fire protection barrier.

Each unit consists of non-deformable cage offering high rigidity and dimensional stability. The insulation component comprises Rockwool® mineral wool that offers inherent fire-resistant qualities. Isotec is formed from 100% Class A1 non-combustible components. An additional benefit is the use of short compression studs instead of compression bars which offer greater concrete design flexibility and simplify installation.Isotec has been thoroughly and independently tested by the French CSTB and holds Avis Technique Number 20/11-232.


  • Inherently fire-resistant mineral wool insulation.
  • Formed from 100% Class A1 non-combustible components.
  • Compression studs reduce rebar congestion and simplify installation.
  • Continuous stainless steel reinforcement maximises strength, thermal efficiency and corrosion protection.
  • Supplied as a complete unit providing rigidity and dimensional stability.
  • Extensive product line to suit a wide range of applications.

0.18–0.3 W/mK depending on construction.

Fire resistance:

120 minutes as assessed by CSTB


Tensile and shear reinforcement consist of 1.4301 or 1.4362 highly corrosion-resistant stainless steel with a minimum characteristic strength Rp0.2 of 500 N/mm². Tensile bars are continuous with no structural welding or point of weakness. Compression studs are manufactured from 12 mm diameter, high-resistance 1.4301 stainless steel bars with hot-forged heads.

In addition to thermal and durability benefits, stainless steel reinforcement reduces concrete cover requirements and can therefore provide additional design efficiencies over carbon steel systems.


Fire-resistant Rockwool® mineral wool insulation is protected by a stainless steel U-shaped profile top and bottom. A label is affixed to the top identifying the system type and direction of placement.
