Lumira aerogel is a material that perfectly insulates against heat and disperses light effectively.
Lumira aerogel is silicate belonging to the group of silica aerogels.
Aerogel is an amorphous form of silica, whose structures inside the pores are calculated in nanometres. About 95% of the volume consists of air, thanks to which aerogel is the lightest solid material in the world.
Effective heat transfer
Due to the low content of solids and a very small pore size (about 20 nanometres), aerogel prevents heat transfer and convection.
Amorphous silica is safe for all construction applications. Aerogel is chemically stable and UV-resistant. It is non-toxic and is classified as a non-flammable material and does not emit smoke. It is permanently hydrophobic, i.e. water-proof, translucent and moisture-resistant. It does not generate conditions for the development of mould or fungi.
Since silica is an inert material (weak in reaction), aerogel can be used and even re-processed for longer than the life of a given system. These unique combinations of features offer the possibility of significant reduction of mass, without the necessity of giving up excellent thermal and acoustic insulation.
As a result, products filled with Lumira® aerogel can be interesting for both new and renovated buildings.
U-values of particular panels
Appropriate U-values refer to vertical mounting positions. After vertical installation, the U-value deteriorates. The U-value for polycarbonate multilayer panels filled with Lumira® aerogel has been tested horizontally, i.e. in the most unfavourable mounting position.
As shown by pictures from a thermal imaging camera, polycarbonate multi-cellular panels filled with Lumira® aerogel have much better insulating properties in comparison to traditional materials. Reddish, much warmer areas are the elements of a single glazing in the Lumira® system.
Perfect light transfer and dispersion
Our system disperses daylight evenly throughout the entire building.
Natural daylight provides a pleasant atmosphere, which has a positive influence on the mind, well-being, motivation and involvement. Lumira aerogel has excellent light transfer up to 90% per 1 cm thickness. Lumira® aerogel introduced into polycarbonate multi-cellular panels increases the incidence of light up to 30% in comparison to standard white-coloured polycarbonate panels.
A significantly important aspect for many users is light dispersion. Daylight, which penetrates Lumira aerogel filling the panels spreads evenly throughout the building. Consequently, glares and direct sunlight concentrated in one place are avoided, which improves lighting conditions and the comfort of use of a room.
Comparison of light dispersion effect
The effect of perfectly dispersed daylight is clearly visible in the following comparative picture, where the difference between the lighting of the hall before the application of skylights with aerogel and after their installation is shown.
Advantages of daylight
The introduction of as much natural daylight as possible in buildings has been the objective of architectural design for a long time.
Studies have shown that people in well and uniformly lighted rooms are healthier and more productive.
