Insulation: liquid double glazing

The innovation of the day is a new technique of both sound and thermal insulation of houses.

We knew the classic double glazing.

Here is now the liquid double glazing.

Instead of keeping air sandwiched between two panes, instead, we're going to pour a liquid.

Not just any, this is a gel specially designed to maximize both sound insulation and thermal insulation.

The result: a window that stifles 15% more noise, compared to conventional double glazing.

It will also protect us better from the cold.

The gel will absorb the heat of the sun during the day, store it and release it at night, to save on heating.

It's good in winter, but in summer?

It could turn the rooms into a sauna.

It is reversible.

There is also a summer mode where the liquid will turn opaque when it is too hot.

So it's like adding blinds: this prevents heat from diffusing inside.

It is an innovation of engineers from Nanyang University of Technology in Singapore.

According to their tests, it would allow 30% savings in heating or air conditioning, compared to the most efficient windows on the market.

Which is huge.

Is this liquid double glazing expensive?

No, that's the good news.

It is cheaper, because there is no need to treat the glass with filter layers like on high performance glazing.

A classic glass is enough.

There are still some drawbacks.

These windows will be much heavier.

So sometimes the frames will have to be changed.

Above all, we could now risk water damage as soon as his window breaks.
