What is the Cost of Secondary Double Glazing?

The cost of secondary glazing is cheaper than that of double glazing. Secondary glazing is when supplementary glass is installed on the inside of an existing single glazed window. This is different to double glazing which uses two sheets of glass with a gap between them creating an insulating barrier.

Secondary glazing is cheaper than double glazing but is not as effective at keeping heat within your property. It also has a lower level of noise insulation and security.

Most properties that are within conservation areas or are listed properties benefit from secondary glazing as it means the original window glass is kept in place.

Secondary glazing is suitable for period properties that need to keep the original features without too much change. Secondary glazing is a discreet and efficient modernisation that allows a property to benefit from better thermal efficiency and security.

Double Glazing Vs. Triple Glazing

You can increase the effectiveness of your double glazing by upgrading your windows to triple glazing. This will raise the cost of your double glazing prices; however, it will also heighten the security and energy efficiency of your home.

A room with triple glazing is warmer than those that have single glazing or double glazing, making triple glazing a popular option, especially when you feel the benefits in the colder months.

What is the Cost of Double Glazing an Entire Home?

Does The Number of Windows Affect Double Glazing Prices?

When Should I Replace my Double Glazing?

Double glazing units tend to have a life span of up to 20 years. Around the 15-20 year mark is where you’ll need to perhaps consider getting your double glazing replaced.

During this time, there may be small maintenance tasks needed to keep it looking good and at optimum condition.

In the unlikely event that you do suffer with issues such as cracks, leaks, draughts and more before the life span is up, you can take a look at replacement glazing solutions or repairs that will save you money and help restore your double glazing to high performance.

Why is Double Glazing so Expensive?

Double glazing is expensive becaustoe of a number of reasons. The main reason is that the units themselves go through a manufacturing process using advanced and intelligent technology and techniques to result in a profile that is durable, long-lasting and hard wearing.

Once the double glazed units have been created, you then have the installation of entire new units into your window frame. We always recommend getting a professional company to install your units to make sure you get the maximum benefit from your double glazing windows.

Secondary glazing is less expensive due to the fact that it is simply applying a second layer of glass to your existing windows.

Double glazing is made to measure, bespoke to your needs and therefore is a more expensive home improvement solution. Despite being a more costly investment, the number of features and benefits that you get in return is phenomenal. You’ll be glad you chose double glazing for your home.
