EXTREME HARDNESS, IT DOESN’T SCRATCH
Glass is a material with a high surface hardness, which makes it very resistant to scratching and abrasion. Unlike plastics, the surface hardness is of 6.5 according to Mohs scale. By contrast, skylights methacrylate or polycarbonate scratch easily, losing its transparency and lighting conditions deteriorate over time.
Glass skylights are easily cleaned using proper tools and detergents, ensuring constant and optimal transparency properties throughout its life. That’s a great advantage for sun pipes, whose dome are usually exposed to dirt environmental, contamination or bird droppings. Unlike plastic, glass look like new once again when cleaned.
HIGH IMPACT RESISTANCE
The sun pipes with tempered glass skylight provide mechanical strength up to 5 times greater than that of conventional float glass, supporting the mechanical requirements set out in UNE-EN ISO 12543-4 with impact of steel ball of 500 gr.
For glass located in sun pipe’s bottom, whose failure might involve risk to people inside the building, safest choice is laminated glass. It consists of two or more layers of glass pressed with butyric sheets between them so that in event of an eventual rupture, pieces stuck together, without removing parts.
WALKABLE SKYLIGHTS. GLASS RESISTANCE
Sun pipe must attend very different applications: private housing, public buildings, hospitals, schools, churches, railway stations, parking’s and so on. Whatever the application, sun pipe’s skylight must rigorously meet its technical and aesthetic requirements.
Double grazed skylight can be designed in a way that you can pass on them, by vehicle or on foot. By introducing butyric you can get laminated glasses with high security performance.
Walkable skylights are designed with tri-laminated glass high strength and can withstand up to 1000 kg in the center of the skylight. This allows its use as even for the passage of trucks and other heavy vehicles.
