UPVC
UPVC, which stands for Unplasticized Polyvinyl Chloride, is a low-maintenance building material used as a substitute for painted wood, mostly for window frames and sills when installing double glazing in new buildings, or to replace older single glazed windows. Aluminium frames do not degrade in the same way that uPVC frames do. Verdict: when looking at uPVC vs aluminium windows for durability, both are weather-resistant and durable.
This means that it is not softened by plasticizers, which can make PVC more flexible and malleable.A vastly popular solution, the high technicality of uPVC windows has taken the market by storm. So much so that uPVC windows have now become synonymous with thermal insulation, acoustic insulation, durability, and enhanced security.
