- Strong and light (large size glass panels can be used)
- Low maintenance and resistant to rot
Weaknesses:

Wood Windows: Classic Look, Constant Upkeep

- Good natural insulation.
- Totally customisable with regards to finish and colour
Weaknesses:

So, Which One Actually Wins?
There is no single best material for every circumstance, but for the majority of homeowners concerned about energy efficiency, durability and reduced upkeep, uPVC Windows is the victor. It combines a unique set of advantages: superior insulation properties when compared to aluminium, it requires virtually no maintenance when compared to wood, and its durability is comparable to both without the ongoing expenses of painting, sealing and corrosion maintenance.
Sleek, minimal frames and big glass panels are what Aluminum excels at. The classic style of wood can only be beaten by those who aren’t interested in the maintenance of wood.
