In curtain wall construction, the embedment connects the main structure to the façade — and it has long carried a stubborn problem. Columns, brackets and base plates are welded over large areas, metal conducts heat quickly, and a thermal bridge forms, bleeding away significant energy. The Prudential green energy-saving channel solves this at the root, and its thermal performance makes it the preferred choice for energy-efficient buildings.
The industry pain point: ordinary embedments, the hidden energy drain
Conventional cast-in channels use a fully welded metal structure with very high thermal conductivity. In alternating hot and cold conditions heat travels quickly through the metal embedment. This not only drives up building energy consumption but also causes condensation and frost, shortening the service life of the curtain wall and running counter to the low-carbon direction of green building.
The Prudential green energy-saving channel: five core advantages
Drawing on years of experience in building anchoring, Prudential has upgraded the green energy-saving channel from material to structure. Five advantages set it apart from conventional embedments:
1. Superior thermal insulation, blocking the heat bridge. A special insulating material forms an efficient thermal layer that completely cuts the metal heat path. With a U-value of only 0.64 W/(m²·K), it eliminates heat-bridge losses at the source.
2. Flexible adaptation, easy installation. The cantilever design accommodates any insulation thickness. Installation requires no complex procedures and suits a wide range of site conditions, greatly improving efficiency.
3. Robust and durable, outstanding mechanical performance. A special structural design balances energy performance with mechanical strength. It carries loads stably, resists corrosion and does not deform over time. Its lateral resistance far exceeds ordinary cast-in channels, reaching over 40 kN.
4. High corrosion resistance, long-term weather durability. A special process leaves the channel free of red rust and visible corrosion after 1,200 hours of neutral salt spray testing, far above the industry norm — lowering maintenance costs significantly.
5. Authoritative certification, internationally recognised quality. Selected channel profiles carry European ETA approval, covering load capacity, seismic performance, fatigue and corrosion resistance. This is a prerequisite for high-end curtain walls, rail transit and international projects.
Proven by testing: the energy-saving effect in numbers
To verify energy performance we ran a controlled comparison, applying dry ice to the outer face of each channel and comparing temperature change between the Prudential green energy-saving channel and an ordinary cast-in channel.
The results were unequivocal: the ordinary channel frosted visibly and dropped to −15.7 °C, while the Prudential channel showed no frost and held steady at around 7.1 °C — a difference of 22.8 °C.
Supported by authoritative test reports, the data clearly shows that the Prudential green energy-saving channel far outperforms ordinary cast-in channels in energy performance.
