H-BAU ISOPRO® and ISOMAXX® Thermally Insulated Balcony Connectors

ISOPRO® and ISOMAXX® Load-Bearing Thermal Insulation Systems

H-BAU ISOPRO® and ISOMAXX® thermal break systems providing low deflection shear and moment connections. They effectively block thermal bridges at junctions where concrete balconies link to the main building structure.

By enhancing the thermal insulation at these connections, these systems boost the building envelope's overall thermal efficiency, aiding in the reduction of heat loss, condensation, and mold growth inside rooms. As a result, H-BAU ISOPRO® and ISOMAXX® systems support compliance with Part L of the building regulations for designers.

ISOPRO® is a load-bearing thermal insulation element that performs the following functions:

  • Thermal separation of reinforced concrete components  to resolve structural design problems at transitions between internal and external components
  • Friction-locked connection of the reinforced  concrete components across the insulating joint
  • The load is transferred across the joint by tie bars, shear bars and a compression component.
  • Depending on the type of ISOPRO® element, the compression component is designed  as a thrust bearing made of special concrete (IP elements)  or as a compression strut made of steel (IPT elements).
  • Reinforcement elements in the area of the insulating body are made of stainless steel to protect against corrosion reduce thermal transmittance through the structural components.
  • Stainless steel is welded to structural steel using a special process. In standard elements, the tie bars in the area of the insulation are made of stainless steel and have smaller diameters than the connected structural steel. 

The ISOPRO® load-bearing thermal insulation element provides a friction-locked connection to external building components. It consists of five main components, all designed to provide reliable force transmission coupled with the lowest possible thermal conductivity.

H-BAU ISOPRO® and ISOMAXX® connection products are available with up to 120 min. fire protection. The ISOPRO®  thermal break system has an 80mm thickness of insulation, and is the most commonly used system to prevent cold bridging. The ISOMAXX® system provides 120mm of insulation for maximum thermal performance.

The H-Bau ISOPRO® and ISOMAXX® range of thermal breaks have been issued with a UK Technical Assessment (UKTA-0836-22/6154) and a European Technical Assessment (ETA 17/0466). The documents provide verification by UK and European building authorities of product performance in up to 120 minutes of fire conditions.

ISOPRO® and ISOMAXX® design software is available from the downloads section of this product page and is designed to assist designers with product selection and load distribution design.  The software enables designs for all common balcony configurations and also enables designs for custom balcony shapes. This aclaimed design software is free to download and easy to use. Technical support is also readlity available from our team of engineers.
