uPVC vs Aluminium
Not all frames are equal Comparing uPVC to basic hollow aluminium frames is like comparing a multi-layer insulated wall to a single- sheet metal panel. Both act as barriers —but only one offers superior thermal insulation, noise reduction, and long- term performance.
The future of innovation
Window Range
Overview
For commercial buildings, uPVC
frames off er a significant advantage in
achieving lower U-values and
improving overall energy performance.
In contrast to hollow aluminium
frames—commonly used in South
Africa but known for their high thermal
conductivity and heat leakage—uPVC
provides superior insulation due to its
low thermal conductivity and multi-
chambered design. This helps reduce
unwanted heat transfer, resulting in
significantly lower U-values that
contribute to energy savings and
improved indoor climate control.
Additionally, uPVC requires minimal
maintenance and offers long-term
durability, making it a cost-effective
and efficient choice for commercial
developments aiming to meet modern
energy efficiency standards.
