Sash windows Double VS Secondary Glazing

Although they are a common design element in many historic homes and structures, sash windows are infamously bad at blocking noise, breezes, and heat loss. Fortunately, there are a number of ways to enhance their performance, such as secondary glazing and double glazing. While both solutions have the potential to be successful, there are some significant distinctions to take into account when choosing which is best for your property.

Double glazing: What is it?

A window with double glazing has two panes of glass with a space between them. An inert gas, such argon, is frequently used to fill the gap, which enhances the window’s insulating capabilities. Double glazing is a popular option for homeowners who wish to increase the energy efficiency of their houses since it is very successful at decreasing heat loss and noise pollution.

How does secondary glazing work?

A window that is added to the interior of an existing window is known as secondary glazing. It comprises of a single glass or plastic pane installed on a separate frame that is clipped or magnetically fastened to the window frame. In addition to lowering noise levels and heat loss, secondary glazing can also increase security and lessen condensation.

For sash windows, compare secondary glazing vs. double glazing

Both secondary glazing and double glazing can be good alternatives for sash windows. There are some significant changes to keep in mind, though.

First off, because it necessitates replacing the entire window, double glazing is often more expensive than secondary glazing. This might be a considerable expense, particularly if your property has numerous sash windows. But secondary glazing is a more affordable option because it involves double the thickness of the current window.

Second, double glazing may be more obtrusive than secondary glazing, particularly if you wish to maintain the appearance of your vintage sash windows. Double glazing frequently necessitates a thicker frame, which might diminish the window’s aesthetic appeal. In contrast, secondary glazing is often less visible from the outside, making it a more inconspicuous alternative.

Thirdly, double glazing is often more successful at preventing heat loss and noise pollution than secondary glazing. This is due to the fact that a double-glazed window’s space between its two panes of glass insulates more effectively than a single pane of glass. But, secondary glazing can still be quite effective, especially if you choose a high-quality product with a low-emissivity coating.

Fourthly, secondary glazing can be easier to install than double glazing, as it does not require any structural adjustments to the current window. If you reside in a listed building or conservation area, where there may be limitations on the kinds of changes you may make to your property, this can be especially helpful.

Conclusion

In conclusion, enhancing the performance of sash windows can be accomplished using either secondary glazing or double glazing. While selecting which one is best for your home, there are a few significant variables to take into account. Secondary glazing is less successful in reducing heat loss and noise pollution than double glazing, which is frequently more expensive and visually intrusive. While secondary glazing is less noticeable and more affordable than double glazing, it might not be as good at preventing heat loss and noise pollution. The ideal option for your house will ultimately depend on your unique requirements and financial situation.
