Nine Questions And Answers About Sash Windows

In the ever-changing climate of the UK, where sunny spells can swiftly turn to biting wind and rain, windows play a pivotal role in our daily lives. 

Replacing old windows with new double-glazed sash windows might seem straightforward, but the wide range of options available can make it a complex journey. At Mortice and Green, we pride ourselves on simplifying the process for our customers. 

Here, we answer ten crucial questions about sash windows to help you make an informed decision if you are thinking about upgrading your sash windows.

What Is Double Glazing?

Double glazing, as the name might suggest, involves two panes of glass separated by a gap filled with insulating gases like argon or krypton. This is a highly effective method for reducing heat loss, hence the popularity in the UK.

What’s Wrong With Single-Glazed Sash Windows?

Back when sash windows were first popular, the technology for double glazing didn’t exist. So, many original sash windows feature only single pane glass. Single-pane windows do serve their purpose, but there are downsides. 

Inefficient single glazing can lead to energy loss, making it challenging to maintain a comfortable indoor temperature. Noise pollution is another concern, impacting your well-being. Additionally, improper insulation can result in dampness, condensation and cold spots in your home.

Do I Need Planning Permission for Double Glazing?

In most cases, installing double or triple glazing doesn’t require special planning permission. However, listed buildings and conservation areas pose some special challenges. Listed buildings may have restrictions, sometimes allowing only like-for-like replacements, so it is worth doing some investigation before you book in the work.

What Is Triple Glazing?

Triple glazing follows the same principles as double glazing but incorporates three panes of glass instead of two. This offers even better energy efficiency and noise reduction, but comes at a higher cost.

Is Triple Glazing Better Than Double Glazing?

Triple glazing offers better noise reduction and insulation, making it a great choice if it fits in your budget. However, double-glazing is also a worthy upgrade from single-glazing, if this option fits better in your budget.

Should I Choose Triple Glazing or Double Glazing?

Choosing between triple and double glazing depends on your location, needs and budget. Noise-prone areas may benefit from triple glazing, but in some areas conservation restrictions might limit your options, making double glazing more suitable.

What Frame Options Are Available?

You have a range of sash window frame options, including timber and uPVC.

Timber: Offers a natural appearance, good insulation and durability and eco-friendliness. Ideal for listed buildings, timber frames come in various hardwoods, factory sprayed with micro-porous paint and certified by The Forest Stewardship Council (FSC).

uPVC: Known for easy maintenance, longevity, excellent insulation, versatility and cost-effectiveness. uPVC can mimic the appearance of timber windows, providing aesthetic flexibility.

How Much Money Can I Save with Double or Triple Glazing?

Energy-efficient sash windows, according to the Energy Saving Trust, offer significant savings on energy bills. The amount depends on the energy rating and type of property.
