BeziFix® Therm-H: The Advanced Façade Fixing System for Modern Construction

In modern building construction, especially in timber and façade engineering, thermal efficiency and structural reliability are critical. One innovative solution designed to meet these demands is the BeziFix® Therm-H, developed for high-performance façade substructures with minimal thermal bridging and maximum load-bearing capability.

What is BeziFix® Therm-H?

BeziFix® Therm-H is a stainless steel screw system used to securely fasten façade battens while supporting insulation layers. It is engineered to carry the full structural load of horizontal and vertical façade constructions, making it suitable for both new builds and renovation projects.
Unlike traditional fixing methods, it integrates thermal insulation principles directly into the fastening system, reducing the need for additional structural layers.

What are the key features?

• Load-bearing structural fixing: BeziFix® Therm-H is designed to transfer the entire load of the façade safely into the substrate, whether it is timber, masonry, or concrete.

• Thermal bridge reduction: One of its standout features is its extremely low thermal conductivity. The system uses A4 stainless steel and aluminium components to minimise heat loss and prevent thermal bridges, improving overall building energy efficiency.

• Adjustable alignment system: The integrated adjustment sleeve allows installers to precisely align façade battens, compensating for uneven walls without additional shimming or complex substructure work.

• High insulation compatibility: BeziFix® Therm-H supports insulation thicknesses of up to 300mm, making it compatible with modern, high-performance insulation systems used in energy efficient buildings.

• Versatile installation: It can be used on a wide range of substrates including timber structures, concrete, brick, masonry and existing ETICS façade systems. This flexibility makes it suitable for both residential and commercial applications.

Benefits of BeziFix® Therm-H

• Quick installation: Because it reduces the need for complex levelling layers and multiple substructure components, installation time is significantly shortened.

• Energy efficiency: By reducing thermal bridges, the system improves the building’s energy performance, contributing to lower heating and cooling costs.

• Structural reliability: The dual-screw anchoring system ensures high load transfer capacity and long-term stability even under heavy façade loads.

• Design flexibility: Architects can design continuous insulated façades without compromising structural integrity or thermal performance.

Applications

BeziFix® Therm-H is commonly used in:

• Ventilated wooden façades
• High-rise façade systems
• Passive house construction
• Renovation of older buildings with external insulation upgrades

Why it matters in modern construction

With increasing focus on sustainability and energy efficiency, systems like BeziFix® Therm-H represent a shift toward integrated structural and thermal engineering solutions. Instead of treating insulation and fastening separately, it combines both into a single engineered system.

This approach not only improves building performance, but also reduces material usage and construction complexity.

BeziFix® Therm-H is more than just a fastening solution, it is a high-performance façade engineering tool designed for the future of sustainable construction. With its ability to support heavy loads, reduce thermal bridging, and simplify installation, it has become a valuable system in modern architectural and structural design.
