Benefits of Thermally Broken Joinery
Thermal break joinery separates interior and exterior aluminium with a low-conductivity strip. It removes cold bridges, lowers U-values and supports regulatory energy models.
Key benefits
- Lower U-values and energy savings
- Reduced thermal bridging
- Less interior condensation risk
- Improved occupant comfort
- Alignment with energy performance codes
Typical applications
- Residential and office schemes
- Healthcare buildings
- Schools and civic projects
- Any development targeting low operational energy
Technical notes
- 24-34 mm polyamide bridges
- Whole-window Uw typically 1.4-2.2 W/m²K
- Dual-seal EPDM gaskets
- Coordinated with glazing Ug values

FAQ
What U-value should we target?
Uw depends on the frame, spacer and glass package. Lower numbers mean better insulation, we model each elevation.
Why does the polyamide strip matter?
It interrupts aluminium conductivity, which otherwise behaves like a thermal highway between hot and cold sides.
Is thermally broken joinery mandatory?
Most new builds in Türkiye require compliant envelope U-values. Thermally broken systems are now baseline for external openings.
