⚖️ Comparing Aluminium Sliding Windows with uPVC Sliding Windows
When selecting sliding windows for your home or office, two of the most popular materials are aluminium and uPVC. Each has its own strengths and weaknesses, and understanding these differences can help you make the best choice for your needs.
This article compares aluminium sliding windows and uPVC sliding windows across key factors such as durability, cost, maintenance, and aesthetics.
????️ Material Composition and Durability
Aluminium Sliding Windows: Made from lightweight yet strong metal, aluminium frames are highly durable, resistant to warping, cracking, and rust. They are ideal for larger windows due to structural strength.
uPVC Sliding Windows: Constructed from unplasticized polyvinyl chloride, uPVC is a type of plastic that is weather-resistant and durable but less strong than aluminium, often limiting window size options.
???? Cost Comparison
Aluminium windows generally have a higher upfront cost compared to uPVC, mainly due to material and manufacturing expenses.
uPVC windows are more budget-friendly and popular for cost-conscious projects.
???? Maintenance Needs
Aluminium frames require minimal maintenance—regular cleaning and occasional lubrication of tracks.
uPVC is also low maintenance, but may discolor or warp in extreme heat or with age.
???? Aesthetics and Design Options
Aluminium offers slimmer frames and a modern, sleek look with a wide range of color finishes through powder coating.
uPVC frames are typically thicker and come mainly in white or limited colors, though newer options have expanded choices.
????️ Energy Efficiency
uPVC windows generally provide better insulation due to the plastic’s lower thermal conductivity.
Aluminium windows require thermal breaks and double/triple glazing to improve energy performance.
???? Security
Aluminium’s strength offers excellent security and supports advanced locking mechanisms.
uPVC is reasonably secure but can be less robust in larger installations.
???? Final Thoughts
Both aluminium and uPVC sliding windows have their place depending on your priorities. Choose aluminium for strength, style, and large openings. Opt for uPVC when budget and insulation are key concerns.
