Detailed Comparison
Durability and Lifespan
Aluminium windows are known for their exceptional durability, lasting 25-35 years or more. uPVC windows typically last 15-25 years and can become brittle over time with prolonged sun exposure.
Strength and Design
Aluminium is significantly stronger than uPVC, allowing for slimmer frame profiles and larger glass panels. uPVC requires thicker frames to achieve the same structural strength.
Thermal Insulation
uPVC naturally provides excellent thermal insulation. Modern aluminium windows with thermal break technology can achieve comparable insulation levels.
Cost
uPVC windows are generally more affordable than aluminium windows. However, aluminium offers better long-term value due to its longer lifespan and superior strength.
Which Should You Choose?
Choose aluminium if you want slim frames, larger glass panels, modern aesthetics, and long-term durability. Choose uPVC if you are on a tighter budget and thermal insulation is your top priority.
