For most people (except for us!), windows are not generally something that is thought about on a daily basis and therefore, become part of the home that are often taken for granted.  However, window styles can actually be one aspect of a house design that really can make or break its success, not just to get the look of your house right, but also to ensure they are practical, safe and efficient for your needs.  So, it’s worth taking a little time to consider all the different window styles available.  In this blog, we concentrate specifically on double hung sash windows – what they are and why they are advantageous to install.

What is a double hung sash window? I hear you cry! Well, double hung sash windows feature two moveable sash sets within the box frame. This means that the window can be opened by sliding the bottom panel up, as well as by sliding the top panel down. Single hung sash windows on the other hand allow ventilation through a single operable lower sash.

What are the advantages of a double hung sash window?

Double hung windows offer extra safety

Many families with young children prefer to install double hung sash windows. They can open the top window for ventilation, and it will be too high for children to reach, making it easier to keep little ones out of harm’s way. Of course, children are curious and may still be able to climb up to the window, so a watchful eye is still needed, and an adult should always be present. Check out the other ways to ensure your sash windows are safe with children around in our blog specifically relating to the topic. The extra level of safety offered by double hung windows are also a good choice for classrooms, care homes, hospitals or anywhere where there is increased vulnerability.

Energy efficiency

If you decide to invest in installing double hung windows in your new or existing property you will definitely be rewarded in terms of energy efficiency. New double hung windows can drastically reduce heating and cooling costs. Old windows are inherently inefficient mainly because they were not designed with energy efficiency in mind. This is true for windows that are more than ten years old. Plus, over the years you may have seen joints loosen or rotten away slightly, all of which will have an effect on the amount of air infiltration coming into your home. Replacing old windows with new double hung versions will not only improve your comfort while at home buy, but you will also see a noticeable reduction in energy loss and more pounds in your purse or wallet.

Maintenance and health

Let’s face it, the more time we can save on tedious, household chores in favour of more time doing the things we love, is always a winner. You’ll be pleased to learn that maintaining double hung windows is as easy as it gets. Most modern double hung models are developed for ease of cleaning and you are even able to clean the exterior of sash windows from the inside. No dangerous ladder climbs, specialised tools or raincoat needed.

In terms of health, double hung sashes are great for keeping the unwanted out and the wanted in. Because the window sashes move up and down, you can let in fresh air and let strong odours out whilst controlling the temperature in the house. Plus, their versatility to move up and down means you can put a screen on the window (unlike casement windows that open out), having a screen installed allows you to keep bugs and debris out without compromising on a well ventilated home.

Add value

Double hung windows are often more desirable than other types of window because of their functionality and safety. As with all quality home improvements, your investment should be reflected in the value added to your home.
