The energy benefits of woven mesh screens on Altair Louvres
Energy benefits of woven mesh screens.

“Can your louvre windows be screened?” is one of the most common questions we are asked. Altair Louvre Windows sure can be screened! They can be screened with fibreglass mesh to keep the insects out, or woven metal mesh to keep intruders out or for bushfire protection. And the screens can be positioned to the outside or the inside of the building.

Most people don’t realise though that mesh screens offer more benefits than protection from insects, intruders and bushfires. Specifically they offer some great energy efficiency benefits in the form of shading and thermal insulation.

Shading like shade cloth
Few people realise it, but its obvious when you think about it: Mesh screens give similar benefits to shade cloth!

  • They’re both woven.
  • They both provide shade (varying amounts depending on the tightness of the weave).
  • You can see through both (again to varying degrees depending on the weave).

In a similar way to shade cloth, woven mesh screens help to keep buildings cooler by reducing the amount of hot sunlight that passes through them and into the building.

Insulation like double glazing
Interestingly, due to the distance between the closed blades of an Altair Louvre Window and a woven mesh screen (a little over 105mm), mesh screens give similar benefits to double glazing!

  • They both trap a layer of air between two vertical surfaces.
  • The layer of air acts as a thermal buffer and so reduces the heat flow between the two vertical surfaces.

When outside temperatures are much higher or lower than comfortable temperatures, this insulation is very beneficial in keeping warmth in, or keeping heat out to improve the efficiency of heating and cooling systems.
