How does each type of solar shading work?
Solar energy from the sun streams through glass, heating everything inside the building. Unable to escape back through the glass, the heat can build up to unbearable temperatures. This is what’s known as the greenhouse effect.
Internal blind systems protect the room from a minimal amount of heat gain. They trap the heat and re-radiate it into the room, also known as the radiator effect.
Solar control glass and window films will reduce a good amount of heat gain but they block the sun’s light, leaving the building occupants in the dark and increasing the need for artificial lighting and therefore, energy consumption.
External solar shading is the most effective protection against heat gain, blocking the sun’s energy from reaching the glass. However, external blind systems reflect the sun’s energy whilst still allowing heat to pass through to the glass and therefore the room. Large louvre systems (Bris Soleil) work by deflecting the sun’s light but only during peak sun hours.
Microlouvre Koolshade® works totally differently. It neutralises solar heat gain and glare before it reaches the window, working non-stop like a heat exchanger dissipating the sun’s heat and energy into the atmosphere. It doesn’t diffuse daylight, it provides all the benefits but not the negative impact of excessive heat gain and glare. The louvres are micro fine, and angled at a level to ensure optimum light in and visibility out, whilst protecting the building occupants from the heat, glare and even external viewing in. It’s known as angular selective technology.
