UPVC vs Aluminium Windows

If you’re struggling to decide on UPVC or aluminium doors, it’s worthwhile knowing the difference between the two.

UPVC windows have been a popular option since the 1980s and, although they are still highly durable and resistant, they tend to need replacing every 20 years, whereas aluminium windows can be replaced every 45 years.

Aluminium windows also do not rust and, because aluminium is a highly conductive material, they are highly efficient.

The cost of aluminium windows vs UPVC is also worth taking into account, as aluminium windows and doors tend to be more expensive than UPVC windows. It’s worth remembering, however, that they typically last much longer.
