How double glazing technology has progressed since the 1980s

Double glazing has been around in one form or another since Victorian times, but it has been mainstream since the 1970s. It is specially designed to reduce heat loss, and it provides greater insulation; reduces condensation, noise, and energy usage; and boosts security.

The savings that could be achieved through installing double glazing in an entirely single-glazed house depend on the size of the property and whether the property is heated by gas or electricity. The annual savings that could be realised for a gas-heated home range from £35 (for a flat fitted with C-rated windows) to £155 (for a detached house fitted with A-rated windows).

How has technology changed double glazing over the last 30 years?

In the late 1970s, leading manufacturer Everest launched its aluminium double glazing range. This was followed by draft-free, maintenance-free, white uPVC. Since then, the innovations have come thick and fast. More recently, double glazing has morphed into triple glazing, and the choice of colours and materials has radically expanded. Triple glazing is still comparatively new in the UK in terms of house-building.

Improved choice

Today, products that are offered with A+ or A++ energy ratings not only reduce heat loss but actively conserve solar heat gain. Windows are available in hundreds of frame designs, dozens of colour combinations, hundreds of glass options, and even a choice of handle colours. Despite this, white remains by far the most predominant colour purchased.

If you are based near the Irish capital and looking for windows Dublin has plenty of firms that can offer a great range of products and services. If you would like further information about having double glazing fitted in your home, why not take a look at the website of a leading company such as


Security remains a high priority for residents, and that manifests itself in toughened glass and highly resistant internal hinges. In the past, window glazing was secured via a strip of plastic, which made it easy for casual burglars to gain entry. Nowadays, the glass is held firmly in place on the inside and, in several cases, is accompanied by robust and effective locking systems.

Eco thinking and conserving heat loss is now mainstream. People want the warmest, quietest, safest, and toughest glazed windows they can afford.
