Everything You Need To Know About Double Glazed Sash Windows

Common problems

Most if not all double glazed sashes suffer from some or all of the following problems:

 

  • Glazing bars are made much too wide in order to hide the double glazed unit edge seals
  • Glazing bars do not have the correct moulding detail Glazing bars are stuck on to the glass
  • Meeting rail splay or rebate is pinned on
  • External glazing bones are stuck on to the glass
  • Glazing beads used instead of putty
  • Mock external putty line stuck on to glass

 

The above design details result in a poorly made and visually unacceptable sash window.

The difference with Bolger Sash Windows

Bolger Sash Windows double glazed sash windows are very different:

 

  • Glazing bars are exact match of original bars
  • Sashes are correctly made – glazing bars are not stuck on
  • External glazing bones are not stuck on. They are housed into the sash in a lattice frame
  • Sashes are putty glazed on the outside

 

The result is that Bolger Sash Windows double-glazed sashes are by far the best-made, which makes them the most authentic, glazed sashes available.

 

We offer a wide range of glazing options including Pilkington Optitherm double-glazing which will reduce the heat loss through the glass by approximately 65% when compared with single glazing.

 

And if you choose BENGglas vacuum glass, your windows will outperform triple-glazed windows in terms of energy efficiency, comfort and soundproofing.
