How to make your Sash Windows more energy-efficient

Sandy says…

It’s about now, when the rain is lashing at the windows, and the wind is howling through the cracks between the window and door frames; that you’re likely to be considering replacements in the New Year!

There are plenty of options available and you can either take a look at our products page (we have a fantastic selection of timber-framed sash windows and doors!) or download our brochure for inspiration while curled up on a comfy sofa – well away from the cold and draughts!

But while you’re deciding which designs you like best – and before your new windows and doors are ordered here are a few suggestions on how to minimise draughts coming through your doors and windows.

Simple, but effective draught-proofing for ash windows

Although it’s usual for sash windows to be traditionally handcrafted by joiners, it’s the very nature of wood to warp and deflect. And, despite sash windows in some historic houses being 100 years old, they need love and attention to keep them performing the best they can.

To keep them draft proof for longer an option is to add draught-proofing strips. These can reduce draughts significantly; and they also minimise the amount of heat escaping through the cracks. A report prepared for Historic England stated that adding draught stips can reduce draughts by an incredible 90%!

Minimising heat loss through old sash windows

It’s not only the cracks in the wood or gaps in the surrounding plaster that cause heat to escape from your windows. The glass itself can be one of the most significant causes of heat-loss.

However, adding heavy curtains and well-fitted roller blinds will reduce the amount of heat lost by a quite significant 30%

Using secondary glazing to help stop draughts

When you add secondary glazing to an old sash window you’re effectively creating a gap between that and the existing pane. This creates the necessary pocket of air that will keep warm air inside and stop the cold air from the outside penetrating the room.

It’s an effective method that retains the original windows but helps considerably with energy-saving. And, although not as effective as replacing the windows, you can reduce heat loss by up to 60% using secondary glazing.

Shutters with sash windows will help keep out the cold

Traditionally, sash windows were fitted with internal shutters to keep the heat in at night and the sunlight out during the summer days. But when cheap and effective heating became available in the 20th Century they weren’t as necessary and quickly became redundant – either removed entirely or, more often, painted shut.

However, as well as looking lovely, if they’re in good condition, shutters can be as effective as double glazing!

Stay warm this winter!

These are just a few of the practical steps you can take to make your sash windows more energy efficient. They can, of course, be used for timber casement windows or metal windows too.

Windows in period properties – whether original or replacements – add to the character of the building. So making the right decisions on draught-proofing and ultimately relacing should be considered carefully. We recommend you research as much as possible and seek all the free advice available from companies such as ours.
