Glass thermal efficiency is an important consideration particularly when it comes to your conservatory or orangery. Glass has been used for centuries to let light into our houses but there’s historically been a trade off in terms of thermal efficiency. With the advent of double glazing, we went some way towards reducing heat loss or overheating of our spaces.

Low-Emissivity Glass

But thanks to modern technology, we can now go even further through the use of Low-Emissivity Glass (e-glass as it’s commonly called). Low e-glass is a type of thermally efficient glass designed to prevent heat escaping through your windows to the cold outdoors. It has an invisible coating to dramatically reduce heat transfer reflecting heat back into your rooms.

Keeping The Warmth In

Unfortunately, many older style double glazed units do not contain thermally efficient glass and are therefore not energy efficient. This leads to higher energy bills, heat leakage and a reduced comfort level. Low e-glass can double the thermal efficiency of your home and reduce your carbon footprint as well as reducing your bills.

Keeping The Heat Out

For spaces such as conservatories, orangeries and garden rooms which have large expanses of glass, thermally efficient glass makes all the difference. Low e-glass helps to retain heat in winter and is particularly recommended for rooms which face north or east. It important to gain as much warmth from the sun as possible and also to retain as much heat from your artificial heat source as possible.

For conservatories, orangeries and garden rooms that face north or west and therefore have a tendency to overheat, there are other forms of thermally efficient glass available. Invisible coatings direct the intense heat of the sun away from the glass while allowing warmth through on cooler days.

The great thing is that thermally efficient glass can be fitted to existing conservatories as well as specified in new ones
