Aluminium Pros: Incredibly strong, enables for ultra-slim sightlines and large glass panels, highly durable, and sleekly contemporary. Cons: Generally more costly than uPVC; older aluminium windows were susceptible to thermal bridging (though contemporary thermal-break innovation mostly solves this). Life expectancy: 45+ years. 3. Lumber (Wood) Pros: Unmatched natural appeal, vital for noted buildings and residential or commercial properties in conservation areas, and extremely customisable. Cons: The most costly alternative; requires regular painting, staining, and sealing to prevent decaying. Life-span: 60+ years (with appropriate maintenance).
