A brief history of double glazing

A brief history of double glazing

The dilemma of how to retain heat in thermally inefficient homes has plagued engineers for aeons. History has recorded that the Romans were the first to try and invent an early form of double glazing over two thousand years ago. Some also claim that the Scots invented double glazing in Victorian times to counter the icy cold houses they inhabited; however, there are no confirmed claims to this, so the earliest established mass production began in the 1950’s America.


Thermopane was the first iteration of double glazing that involved the bonding of two layers of glass incorporated in a frame. The inventor, CD Haven, was awarded a patent for his invention, and mass production began in earnest after the conclusion of the Second World War. The 1950s was a time of prosperity in America and homeowners were able to indulge in purchasing modern appliances like refrigerators while keeping their homes warm with double glazed windows.

Double glazing in the UK

Double glazing was introduced to British shores in the 1970s. In 1965 the Labour government of Harold Wilson brought forward legislation for Building Regulations to address the hideous thermal inefficiency of British homes. By the ’70s, double glazing was more affordable for the general population and was seeing efficiency increases with each new invention. Homeowners could now see that their new windows and doors were saving them money through reduced energy bills.

Further innovations and Fensa

After the masses caught the double glazing bug, bay windows, patio doors and conservatories became a common sight in the suburbs of Birmingham. Triple glazing and even self-cleaning glass have provided further innovation but perhaps the founding of FENSA, set-up to ensure standardisation across the industry, has done more than anything else to improve the reputation of double glazing firms.
