How we double glaze your sash windows?

MD Sash Windows - double glazing

If your sash window box frames are in good condition, we can craft and fit new wooden sashes specifically designed to accommodate modern double-glazed glass panes. These new sashes are meticulously made to mimic the original single-glazed appearance, making them ideal for properties in conservation areas.

Our double glazing solutions offer:

  • • Enhanced thermal insulation for warmer rooms
  • • Significant reduction in outside noise with acoustic glass options
  • • Increased privacy with obscure glass choices
  • • Custom-made sashes that fit existing box frames
  • • Compatibility with traditional period aesthetics
