Sash windows are a timeless and elegant feature in any type of home. Here is more information on restoration, history, and style along with how to go about choosing new sashes and when to replace them.

What Is A Sash Window And How Do They Work?

“Sash” is a word that refers to single-frames for glazing, for example veka windows. The sliding traditional sash windows come with 2 sashes that are able to slide upwards or downwards. To explain this further, these windows work in the way of balancing a sash using a counter-weight made from a leaden, cast-iron, or steel weight, which is hung a cord. The weight is hidden inside the hollow-box frame. You can retrofit insulation in the pockets of older windows.

These classic designs are more common in Victorian and Georgian properties, along with a few variations in the late Edwardian and Victorian homes.

Sash Window Styles

When it comes to replacing the windows on older properties or choosing a new design for period-style homes, it becomes important to choose the correct time period. There have been a number of style changes and developments to the sash windows in the last few years, so make sure you are getting the right one.

The traditional sashes are made of several “lights” or small panes. These panes are attached together with astragal bars or glazing bars which results in a larger sized glazed area. This had to do with the glass at that time that did not allow for big expanses of glazing.

Should I Replace Or Repair Sash Windows?

It is unwise to remove timber sashes from an original period and replace these with the latest models. When possible rather waterproof and restore your existing sashes.

The advantages of repairing over replacing when possible include:

• The home will retain its original character and charm.
• You can benefit from thermal performance improvements with draught-proofing and double-glazing when you retain the box-frame and replace the glazing.
• Original timber in most cases is a far better quality in comparison to the products that we can buy today.

The Costs Involved To Replace Or Restore Sashes

You can replace the glazing in your sash windows provided that the frames are still salvageable. When it is possible to restore the windows, a single-glazed panel is easy to upgrade to a double-glazed slim panel. You can also choose to install new sashes into an existing frame. The repair specialists for sash windows estimate a price from £1,000 or more per window.

What Types Of Materials Should I Use For A Replacement Sash Window?

1. Timber Sash Windows

For people residing in Conservation Areas or the traditionalists, or for listed buildings, the genuine-timber sash window is usually the only and first choice. Plastic just cannot realise a tactile effect that is the same. Here are some of the benefits of timber sash windows:

• A great insulator
• Long-lasting when properly maintained
• Durable

2. PVCu Sash Windows

The PVCu also is known as uPVC is a popular alternative for painted wood. Even though the main colour is white, they do come in a variety of finishes and colours, which includes a photo-effect wood finish.

• Energy efficient (yet not a sustainable choice as these materials can’t be recycled)
• Low-maintenance

3. Composite Sash Windows

Composite sash windows are growing in popularity. The latest product offering includes timber which is used for the interior, while aluminium-cladding is used for the exterior. Some of the advantages of these sash windows include:

• They maintain a classical wood appeal from the inside
• The outside is virtually maintenance-free

Glazing In Sash Windows

The latest building regulations have made it close to impossible to use single-glazed windows on new homes, so this might mean that you might not achieve true authenticity. However, it is possible to use single-glazed windows for most renovation projects.

Double-Glazing In Sash Windows

Breaking up the smaller double-glazing units with the use of thick bars often appears to look clumsy, yet it is possible to recreate glazing bars that are finer. The easiest method includes bonding the mock bars on each side of the double-glazed unit. It is also possible to include spacer bars in between each glass sheet, which will enhance the overall effect.

Triple Glazed Sash Windows

The triple-glazed options are also available in traditional styles, yet they come at a premium price. However, the latest triple-glazing options no longer carry the “cost stigma” which it was known for over the last few decades.
