Window Republic produces all types of classic timber sash windows, meeting the needs of UK properties.

We always aim at maximising the original charm of your period property by re-producing exact copies of the original sash windows. When we are working in London, many councils have strict design and quality rules.

We are one of few companies that is pre-approved by Conservation Areas in London such as the Mapesbury Conservation area.

We only use the highest quality soft & hardwood timber for our sash windows:

  • Nordic Pine
  • Siberian Larch
  • Oak

We only use engineered quality wood for optimal product durability. If properly maintained, our sash windows will last a lifetime, and beyond.

For the glazing we use the most modern double glazing technology that is currently on the market. All our double glazing is Argon-filled and offers a 1.4W/(m²K) to 1.5W/(m²K) U-Value and are 'B' energy Rated. We source our glass from major manufacturers such as Saint-Gobain® and SZILÁNK®.

White Edgetech super spacers or white aluminium spacers within the double glazing units produce an optimal visual blend-in.
