One of the primary concerns during historical restoration is ensuring longevity. uPVC doors and windows are renowned for their durability and low maintenance requirements. Unlike traditional wooden frames, uPVC does not rot, warp, or deteriorate over time. It is resistant to moisture, pests, and UV radiation, making it an ideal choice for long-term preservation. Moreover, uPVC frames do not require regular painting or sealing, eliminating the need for extensive maintenance efforts. A simple cleaning routine is sufficient to keep them looking pristine for years to come.
