Getting the best from your double glazed Sash windows

It may be that you are thinking that one replacement sash window is just as good as another when it comes to saving from losing heat and that could be true for you unless you knew about a few innovations that are not included as standard, but can make quite a difference in terms of energy saving properties and can also impact on the cost guide.

How Much Does it Cost to Replace Windows?

UPVC Sash WindowsTwo of the small items that can have a significant effect on upvc sash windows are

1) spacers

2) weather seals.

The spacers fitted inside the double glazed sealed glass panes can transfer some heat, especially some metal versions, this can be greatly eliminated by using ‘warm edge spacers’ which a far better at insulation.

The weather seals are small brush like seals which run around the edge of the windows and are the key to keeping out draughts and water penetration caused by capillary action.

Just paying attention to these 2 small things could save you money in the long run. Especially for the sides of the frames where the sashes slide up and down. If the weather seals are not effective here, you can get some nasty draughts coming into your home.

You could also upgrade the double glazing for your upvc sash windows.

  • if your older timber windows are in good shape, it’s worthwhile considering secondary double glazing on the inside. It will make a huge difference in blocking external noise and stop draughts or heat loss effectively.
  • If you have B, C energy rated (or lower) windows and the frames & sashes are otherwise fine, then maybe consider just getting new double-glazed units. Glazing with a wider gap between the panes, especially if that gap is filled with Argon gas, improve energy efficiency a lot.
