Introduction – When Double Glazing Invented

There is some debate as to when double glazing was actually Double Glazing Invented. However, the vast majority of historians on the subject seem to agree that C.D. Haven in 1930s America Double Glazing Invented it. Keeping heat in the home was notoriously difficult for centuries, particularly in bigger houses, as a single fire was often all anyone had. Spotting an issue that needed solving, as most great inventors do, Haven coined the earliest form of double glazing as ‘thermopane’.

His idea was to use two panes of glass to keep the home insulated rather than just one. There is conflict on whether he was actually the first person to do this as there are records of various other homes having two panes of glass instead of one as far back as 1870 in Scotland, Germany and Switzerland, where the winters were particularly harsh and the insulation provided was necessary to ensure a family’s survival through the cold.

Regardless of the conflicting opinions about when it started, Haven’s invention was the one that took off in the United States, gaining massive popularity across the country. Once established as the proper way to keep the home insulated, UK manufacturers started incorporating a dual window system in the mid-1960s. This process involved taking the rotting timber frames out and replacing the installation with fresh timber and double glazing.

By the time the 1970s rolled around, timber was going out of fashion, and the UK was crying out for aluminium installations that promised to last longer, provide greater security, and give homes an ultra-modern finish. However, aluminium proved to be lacking in thermal efficiency compared to timber. Luckily, the parallel rise of uPVC as a building material over the course of the 20th century saw that uPVC could step into place as the standard pairing with double glazing for the modern home. In the 70s, only about 8% of UK households had double glazing insulation, whereas now, 93% of homes in the UK are fitted with double glazed windows and doors.

The main benefits of Double Glazing

Double glazing’s simple manufacturing process is part of what makes it so attractive to installers and so affordable for the UK household. Two panes of glass are put together within the uPVC, timber or aluminium frame and are separated by a spacer. The gap between them is then made into a vacuum with an insulating gas, such as argon, which is then inserted to give the installation the extra layer of insulation required.

Having the gap sealed in a vacuum makes it impossible for moisture to enter between the two panes, keeping your home safe from condensation. Furthermore, the insulating gas keeps temperatures from moving between the two panes of glass, essentially keeping the cold air out and the warm air in. This also works the other way during the summer when it is exceptionally hot, and you’re trying to keep the home cool.

The major benefits that have come from C.D. Haven’s invention are:

  1. Increased thermal efficiency, leading to lower energy costs overall.
  2. Enhanced security throughout the country, lowering home burglaries and invasions.
  3. Much improved noise reduction, reducing complaints and keeping homes private.
  4. Increasing the value of the UK housing market by having high-performance homes available for everyone.

These benefits would not have been possible without the advent of double glazing entering the market as the standard installation for all homes across the UK.

As we move forward, it is starting to look like triple glazing will overtake double glazing as the standard for our homes. Triple glazing works much like double glazing except with three panes of glass and two layers of thermally insulating gas. Of course, it makes complete sense scientifically and practically that triple glazing would only improve on double glazing. However, its high price point keeps homes from jumping on the craze just yet. However, with rising energy costs across the UK and beyond, it is likely that we will see a greater demand for homes with overall lower energy costs as we move forward into this decade.

Double glazing has been an innovative invention that has transformed homes throughout the United Kingdom and beyond. From its early beginnings in the Thirties to its significant adoption inside the 1970s, double glazing has provided owners with increased thermal efficiency, enhanced security, advanced noise discount, and higher asset values. As power prices preserve to upward push, the call for even more green solutions like triple glazing may additionally emerge as more regular inside the coming years. Nonetheless, double glazing remains a dependable and value-effective choice for those looking to improve the comfort and protection of their homes while reducing their energy bills.


How does the spacer in double glazing make contributions to its thermal efficiency? 

The spacer in double glazing performs a critical role in preserving the vacuum among the two panes of glass. It additionally helps to prevent moisture from entering the distance, which can cause condensation problems. By retaining the insulating gas sealed in the vacuum, the spacer ensures that the double glazing machine remains thermally efficient.

Can double glazing be installed in listed homes or homes in conservation areas? 

Yes, double glazing may be mounted in indexed buildings or homes in conservation regions, but it could require special permissions and adherence to unique guidelines. In some cases, alternative materials like wooden frames can be required to hold the historic integrity of the building. It is important to seek advice from nearby government and professionals before proceeding with any installations.

How lengthy does double glazing normally final, and what protection is required? 

Double glazing is designed to remain for decades, with some producers presenting guarantees of up to 20 years or extra. However, the lifespan of double glazing can be inspired with the aid of elements consisting of the niceness of the installation, the substances used, and the level of maintenance furnished. Regular cleansing and checking for symptoms of wear or damage can help to increase the life of double glazing.

Can double glazing lessen outside noise pollutants efficiently in urban areas? 

Double glazing is a powerful answer for lowering outdoor noise pollution, especially in city areas with excessive stages of traffic or different external noise resources. The vacuum among the 2 panes of glass, in conjunction with the insulating fuel, enables it to take in and block sound waves, developing a quieter and extra non violent indoor environment.

Are there any authorities incentives or grants available for upgrading to double glazing? 

In some instances, there may be authorities incentives or presents available to help owners upgrade to double glazing. These can range relying on region and particular occasions, consisting of profits level or the power efficiency score of the belongings. It is worth checking with nearby authorities or electricity carriers to look if any schemes are currently available to your vicinity.
