Key Benefits

A high-performance polyamide barrier interrupts energy flow between inner and outer aluminium frames — improving insulation, comfort, and energy efficiency.

Glass-fibre reinforced polyamide physically severs the conductive path between interior and exterior aluminium chambers — eliminating cold bridging at the source.
Blumium's thermal break reduces heat transfer by over 95%, eliminating surface condensation, radiant cold, and energy drain.
Designed for Double Glazed Units, the argon-filled glass works in tandem with thermal break frames to deliver overall system U-values as low as 1.6 W/m²K.
Engineered for durability, comfort, and sustainable building performance.
The polyamide strip breaks the conductive path. Heat stays out. HVAC works less.
No temperature differential at the frame surface — no moisture buildup or staining.
Multi-chamber design interrupts acoustic paths, attenuating up to 38 dB of exterior noise.
Absorbs differential thermal expansion, reducing stress on seals and gaskets over time.
