Unlike wooden doors and windows , aluminum doors and windows require very low maintenance, an advantage which also translates into significant cost savings over the life of the product. Aluminum is a material with a low environmental impact: in addition to being entirely recyclable, unlike PVC, it has great resistance to atmospheric agents and therefore greater durability over time. The great advantage of aluminum compared to PVC is the unlimited availability of finishes, such as to ensure the satisfaction of any need and aesthetic taste. The aluminum doors and windows, in fact, thanks to the variety of profiles and the wide range of colors available, consentono di ottenere e personalizzare svariate soluzioni adattandosi alle esigenze delle moderne architetture, sempre più alla ricerca di profili minimali: dai locali commerciali, alle vetrine e facciate continue, alle costruzioni private.
