Aluminium windows tend to be more expensive than uPVC windows due to a higher cost of materials and manufacturing. In addition to the lower initial price, the better thermal efficiency of uPVC frames can mean that they contribute to lower heating bills in the long run.
Alongside their thermal efficiency and lower costs when compared to aluminium window frames, UPVC frames also offer benefits in terms of security. With multi-point locks that are built into the frames as standard, the frames can be a much more secure option for preventing unwanted intruders getting into your property.
UPVC is a high-quality material which is resistant to rot and provided that it the frames are regularly cleaned and maintained, they will last you for many years.
