Thermal Break Sliding Windows
Aluminium Profile System for High-Performance Energy-Efficient Sliding Window Solutions
Product Overview
Thermal Break Sliding Windows are advanced aluminium architectural window systems engineered with a PA66 polyamide thermal barrier strip placed between the interior and exterior aluminium profiles. This structural design effectively interrupts thermal conductivity, significantly improving insulation performance and reducing energy loss.
Compared with conventional aluminium sliding window systems, thermal break solutions deliver:
- Superior thermal insulation performance
- Enhanced acoustic comfort
- Improved condensation resistance
- Higher energy efficiency compliance
These systems are widely used in energy-efficient residential buildings, commercial facades, and high-performance architectural projects across Europe, the Middle East, Southeast Asia, and coastal regions.
As a professional aluminium extrusion manufacturer, we provide fully customizable thermal break sliding window profile systems compatible with international architectural standards and project-specific engineering requirements.
Engineering System Structure & Working Principle
System Composition
Inner aluminium profile (interior side)
Outer aluminium profile (exterior side)
PA66 GF25 polyamide thermal break strip
Multi-track sliding frame system (2/3/4/6 track options)
EPDM high-performance sealing system
Double / triple glazing compatibility system

Working Principle
The thermal break system uses a non-conductive polyamide barrier to separate interior and exterior aluminium profiles, effectively reducing heat transfer pathways.
This structure minimizes:
Heat loss in cold climates
Heat gain in hot climates
Internal condensation formation
Energy consumption of HVAC systems
