Double Glazed Windows vs Sealed Glass Units
Double glazing is quite a niche subject at the best of times, with lots of terms to get your head around. What are sealed glass units and how is that different from a double glazed window?
Double Glazed Window
When we talk about double glazing, we usually mean the full window. This includes the glass, the frame and everything that goes into windows. Our 10-year guarantees refer to the frame, covering parts and labour.
Sealed Glass Unit
When we say sealed glazed unit, we mean the glass in the frame. This consists of a spacer bar, two glass panels, the void between filled with inert gas and an airtight seal around the edge. This unit goes into the frame and makes up a double glazed window.

On average, double glazing windows can last between 20- 25 years, with many lasting even longer. The lifespan of double glazing can be extended with proper care and maintenance, such as cleaning the frames and glass regularly and checking for any signs of wear and tear. Look for companies with long guarantees such as Anglian, as this can be a good sign of the expected lifespan.
The cost of double glazing can vary depending on several factors, such as the size and type of the window, the material of the frame, the type of glass used and the installation costs. As a general guideline, the cost of double glazing for a standard-sized window can range from a few hundred to a few thousand pounds, depending on the above factors. But it's important to note that the cost can be higher for larger or more complex windows, or for windows made from premium materials.
Triple glazing is generally more efficient at reducing heat loss than double glazing, but it may not always be necessary or cost-effective. The exact energy savings achieved by triple glazing will depend on a variety of factors such as the climate, the orientation of the windows, the building's insulation, and the efficiency of the heating and cooling systems in your home. In some cases, double glazing may be enough to meet energy efficiency standards, especially if you have other energy-saving measures such as wall insulation.
Double glazing is a type of window that consists of two panes of glass with a small gap between them. The gap is filled with air or an insulating gas like argon. The two panes of glass act as a barrier to reduce the amount of heat that is transferred through the window. This provides increased insulation, which can help to reduce heat loss from your home and improve energy efficiency.
Double glazing reduces heat loss through the window by creating a barrier that slows down the transfer of heat. Heat can transfer through a window in several ways, including conduction, convection, and radiation. The two panes of glass and the air gap between them work together to reduce the amount of heat that is transferred through the window. This means double glazing helps to keep your home warmer in the winter and cooler in the summer, which can result in lower energy bills and increased comfort.
