When history comes back to life – how we renovate historic windows and doors

Old windows and doors are more than just simple structural elements. A special window frame, a finely carved sash, or a century-old lock—all these details contribute to the character, history, and atmosphere of a building. That is why, when renovating a historic or heritage building, the fate of the original windows and doors is not just a technical issue – it is also a cultural responsibility.

Many people believe that modern comfort and energy efficiency requirements can only be met by installing new, state-of-the-art windows and doors. However, at Greenwood, we believe that old values and modern technology can coexist harmoniously – if we approach them with the right attitude and expertise.

Our company has decades of experience in the restoration of historic windows and doors. In our work, we strive to preserve the original appearance of the window or door—its shape, details, and colors—while ensuring that the internal structure fully complies with today’s thermal and sound insulation requirements.

On the inside, we use modern, well-insulated window sashes, while on the outside we retain or reproduce the original mullion solutions. This allows the building to retain its aesthetic value, while significantly improving the comfort of its inhabitants.

Environmental awareness is also important to us: we only use FSC-certified wood, which ensures that the wood used comes from sustainable, responsible forestry.
