Three is the magic number: the benefits of triple glazing in sustainable homes

Posted 18 September 2015

Triple glazing takes insulation and energy savings to the next level, and you can expect to see them as standard in Trivselhus by Esh homes.

When it comes to living in a warm, energy efficient and protected home, three really is the magic number. In the 19th and early 20th century single-glazed windows were used throughout homes as a way to maintain light in a property without exposure to the wind and rain. But as our understanding of thermal energy and housing technologies have moved on, they are now considered relics.

Single glazing offers scant protection from the elements, leaving householders to cope with cold conditions and extreme condensation. In real terms, single glazing haemorrhages heat, and over the course of a year can amount to hundreds of pounds worth of extra heating costs. In fact, single glazing is so inadequate that it’s no longer permissible to use it in new builds.

Double glazing is considered a standard requirement in homes across the UK. But even the latest double-glazed windows are now understood to have their drawbacks. It is for this reason that more and more homeowners are turning to triple-glazing as an option.

There are a number of reasons why triple glazing is considered superior to its single and double pane alternatives.

A measured performance

Window efficiency is measured in the same way as that of walls, roofs and floors. The U value is a measure of heat loss – the lower the value, the less heat is being lost and the better the window’s performance.

While old-fashioned, single-glazed windows typically exceed a U value of 5, modern, well-designed double glazing can bring the U value down to 1.6 – which complies with mandatory requirements stipulated under Building Regulations. However, triple-glazed windows are capable of halving that U value to a mere 0.8. As part of building a sustainable, low energy home this improvement in thermal efficiency can be significant, particularly in builds utilizing large panes of glass to maximize light in living spaces. In fact, triple glazed windows are almost as efficient as modern walls, which are currently required to have a U value of 0.3.

Triple glazing as standard

Triple glazing is a common feature in Scandinavian countries such as Sweden and Norway, where the climate is much colder during the winter months. To meet housing standards, Swedish homes must not only feature three panes of glass but also insulated frames, using cutting-edge manufacturing techniques.

In Scandinavia it is understood that insulating the rest of a home but failing to fit triple glazing can actually create cold spots surrounding the windows at night. The resulting draughts and build up of condensation on the panes have a significant impact on temperature and comfort within the home.

Triple glazing with Trivselhus by Esh

All Trivselhus by Esh homes are triple-glazed as standard, meaning that there is no break in the warmth and comfort enjoyed by Trivselhus by Esh homeowners. There are no cold spots by windows, no draughts to fight with awkward excluders and every part of the house – the floors, the walls, the roof and the windows – work together to preserve heat. Along with brilliantly efficient mineral wool insulation and an airtight membrane, the triple glazing in Trivselhus by Esh homes are fitted to the very highest of standards,

Trivselhus by Esh windows also complement the homes’ other intelligent design features, such as the air source heat pump and mechanical ventilation, too. Additionally, the three panes of quality glass afford much-improved protection against noise pollution. So whether householders are concerned with keeping external sounds out or protecting the neighbours from the perils of noisy pets and children, they needn’t worry.
