How does Aerolite improve the temperature in my home in summer and winter?

As a matter of fact, Aerolite insulation will reduce the heat flow into the home in summer. In fact, ceilings that are not insulated are very hot in summer. Of course, this is like underfloor heating above your head in summer. The 135mm Aerolite insulation blanket laid on the ceiling between the beams reducing heat flow up or down by up to 90%. As a result of the Aerolite reducing the heat flow into the home the temperature can be as much as 5 to 8 degrees cooler. Making the home far more comfortable and reducing the need for Air conditioners in most cases.

In Winter the roof space is like a fridge as cold wind and air flow through the roof space. The ceiling area now is freezing cold. Any warm air that is created in the home from heating or cooking or even sunlight is lost. As this warm air will rise and subsequently lost to the cold roof space. In fact, a home that is using a heater or small fireplace will warm up most of the home. As the rising heat will not be lost into the roof space. Here is more info on how Aerolite works in summer and winter.

What Is Aerolite Lifespan?

The fact that Aerolite insulation is manufactured from 80% recycled glass and 20% naturally occurring silica sand means it will last for many years. The manufacturers state a lifespan of 20 to 25 years. However, we have been installing Aerolite for almost 30 years now. And we are doing retrofit insulations on homes insulated more than 25 years ago. This retrofit is in order to bring the old insulation that was much thinner those years up to spec with the new R value specifications on all new homes.

Braai Room Insulation? 

The Braai room is one of the most popular rooms in most homes. These rooms although the most popular room in the home they are also the hottest in summer and the coldest in winter.
