Understanding insulated glazing for sash windows
You may not know this, but insulated glazing is actually pretty important – especially if you’re looking to keep your sash windows in good condition. In fact, insulated glazing can help to improve the energy efficiency of your home, which is always a bonus.
What is insulated glazing?
You may be wondering what exactly is insulated glazing. Insulated glazing, also known as IGU, is two or more panes of glass separated by a spacer and sealed together. The spacer is filled with air or gas to reduce heat transfer.
There are many benefits to having insulated glazing in your sash windows. One benefit is that it can help to reduce your energy bills. This is because it helps to keep heat in during the winter and out during the summer. It can also help to reduce noise pollution from outside.
How does it work
Insulated glazing is a type of window construction in which the panes of glass are separated by a spacer and sealed with a special sealant. The spacer is usually made of metal or plastic, and the sealant is typically a silicone-based material. The purpose of the spacer and sealant is to create an airtight barrier between the panes of glass, which prevents heat transfer and makes the window more energy efficient.
The most common type of insulated glazing is double-glazed, which means that there are two panes of glass separated by a spacer. Triple-glazed windows are also available, but they are not as common. Quadruple-glazed windows are very rare.
What are the benefits?
Insulated glazing can help to improve the energy efficiency of your home, as well as provide additional soundproofing. It can also help to keep your home cooler in summer and warmer in winter.
Single glazing vs double glazing
There are two main types of insulated glazing for sash windows- single and double. Single glazing is made up of a single layer of glass, while double glazing has two layers of glass with a space in between them. Double glazing is more energy efficient than single glazing and is the best option for most homes.

How much does it cost?
You’re interested in insulated glazing for sash windows and want to know how much it costs. Insulated glazing is a great way to improve the energy efficiency of your home, and can save you money on your energy bills. The cost of insulated glazing will vary depending on the size and type of window.
How long does glazing last?
Insulated glazing is designed to last for the lifetime of the window. The seal between the panes of glass is what keeps the insulation in place, and that seal is designed to be permanent. There are a few things that can damage the seal and cause the insulated glazing to fail, but if the windows are properly maintained, they should last as long as the window itself.
One thing that can damage the seal is exposed to excessive heat or cold. If the windows are in an area that gets a lot of direct sunlight, for example, the heat can cause the sealant to break down over time. Similarly, if the windows are in an area that gets very cold in winter, the extreme temperatures can also damage the sealant.
Another thing that can damage the seal is condensation. If there is a lot of moisture in the air, it can get between the panes of glass and cause the sealant to deteriorate. This is why it’s important to keep your windows clean and free of any buildup of dirt or dust, which can hold moisture and lead to condensation.
If you take care of your windows and avoid exposing them to excessive heat or cold or moisture, your insulated glazing should last for many years.
How can I tell if my windows have insulated glazing?
One way to tell if your windows have insulated glazing is to look for a label or stamp that says “IG” or “Insulated Glass.” Another way to tell is to look at the thickness of the glass. Insulated glass is usually thicker than regular glass. You might notice two shadows cast by the two panes if you look closely.
How do I clean and maintain my insulated glazing?
To clean your insulated glazing, you will need to use a mild soap and water solution. You can also use a vinegar and water solution, but be sure to rinse the area well afterwards. For tougher stains, you may need to use a glass cleaner or other commercial cleaning product. Be sure to follow the manufacturer’s instructions for any cleaning products that you use. It’s worth having a window cleaner do your windows regularly if you have not got the time or inclination.
Are there any special considerations for the installation or replacement of insulated glazing
There are a few special considerations to take into account when installing or replacing insulated glazing in sash windows. The first is the weight of the glass-insulated glazing is typically much heavier than single-pane glass, so the window frame will need to be reinforced to accommodate it. Secondly, the installation process is slightly different – insulated glazing is sometimes installed from the outside of the window, rather than the inside. This means that any existing trim or moulding may need to be removed before installation can begin. Finally, it’s important to choose a reputable and experienced installer, as incorrect installation can lead to problems such as leaks or drafts.
What types of window treatments can be used with insulated glazing
Different types of window treatments can be used with insulated glazing, including curtains, blinds, and shutters. Insulated glazing can help to keep your home warm in the winter and cool in the summer, and combined with inside window treatments you are onto a winner.
A recap
Insulated glazing is a type of window construction that uses two or more panes of glass separated by a spacer. The spacer is filled with a gas, typically argon or krypton, which improves the thermal performance of the window.
There are several benefits to using insulated glazing in sash windows. First, it can improve the energy efficiency of the window by reducing heat loss. Second, it can reduce noise transmission through the window. And third, it can improve the comfort level of the room by reducing drafts and cold spots.
