Unlike metals, PVCu is non-conductive meaning its use in window frames does not transfer heat and therefore contributes to a more consistent internal temperature for a building. The combination of PVCu window frames and double glazing makes for highly energy efficient windows.
PVCu window frames don't need painting or sealing which significantly reduces the maintenance required over their lifetime. They are easily cleaned with water and detergent.
PVCu windows incorporate multi-locking systems providing a high level of security for homes or businesses. Most PVCu window locking systems lock at multiple points all around the sash and frame.
