Special domes with fire resistance Broof(t1)

Chatron's SafeProof Dome? consists of a pyramid-shaped polycarbonate dome and a layer of tempered laminated glass. This constitution allowed it to pass rigorous external fire tests in accordance with EN 1350-5:2016, obtaining Broof(t1) certification.

Why does the SafeProof Dome? (Chatron) stand out from the competition?

Chatron's SafeProof Dome? goes far beyond fire safety, offering a series of additional benefits compared to traditional flat glass domes from competitors which, although they may have the same distinction in fire safety, are very limited in other requirements. Let's look at the advantages of Chatron's innovative SafeProof Dome? when compared to the competition's flat glass domes:

1. More natural night: The pyramidal shape of the SafeProof Dome? allows for a capture of more than 40% (more natural light) when compared to flat domes, especially during times of lower light. The larger collection area provides a greater diversity of light input that is dispersed evenly, avoiding concentration points and providing a more uniform entry of light into the solar light tube.
2. Effect of pyramidal dome prisms: The pyramidal dome has 5 main prisms and an additional, rim-like prism around the entire area of the dome, which act like prisms, decomposing the natural light that falls on them into beams of light, dispersing it throughout the interior of the solar light tube. This dispersion increases luminosity and lighting power, contributing to a brighter and more natural indoor environment.
3. Protection against UV rays: The SafeProof Dome? offers total protection against UV rays, as the pyramid-shaped polycarbonate dome blocks virtually all UV rays before they reach the tempered laminated glass. In this way, the light that goes inside is devoid of harmful and harmful rays, for example, for the dechlorination of objects inside, also protecting the health of the occupants and reducing the risk of diseases related to excessive exposure to UV rays.
4. Efficient self-cleaning: The inclination of the dome faces prevents the accumulation of water and debris, facilitating self-cleaning and consequently reducing the need for maintenance. The smooth surfaces of competitive flat domes make self-cleaning difficult, thus contributing to the accumulation of debris, the proliferation of fungi and bacteria and the consequent deterioration of transparency and the passage of light into the interior.
5. Deterrence of birds and insects outside:?The pyramidal shape of the SafeProof Dome? makes it difficult for birds and insects to land, avoiding problems with dirt and damage to its surface.
6. Reduction of shading: The elevation of the dome, when compared to the competition's flat dome, allows natural light to penetrate even in areas with obstacles on the roof, minimizing the shading effect.
7. Unparalleled security: The SafeProof Dome? is the only "non-flat" dome on the market that has passed rigorous fire resistance tests (Broof(t1)). All other competitive domes with this certificate are flat, without the advantages mentioned above.
8. Better thermal performance and total elimination of condensation: The SafeProof Dome?, due to the fact that it has this "double dome" on the outside, does not directly expose the air present inside the solar light tube with the dome on the roof, which in turn is in contact with the outside. As there is a pyramidal dome completely surrounding the flat tempered glass inside, it will function as an air chamber between the outside and the inside, greatly improving thermal performance. This happens, on the one hand, because polycarbonate has much better thermal characteristics when compared to glass; on the other hand, because it prevents condensation on the glass, as may happen in certain weather conditions with competing flat domes (mainly in cold countries), as these are directly exposed, with the glass, to the outside environment.
9. Innovative Design: SafeProof Dome? is a robust solution with an innovative and integrative design. These were basic elements present in the design and development of the dome so that it was simultaneously capable of fire resistance and good luminous and thermal performance. In contrast, the competition's flat domes were developed solely and exclusively to obtain the fire resistance certificate, presenting very poor performance in the remaining parameters.

The Valencia tragedy and the importance of fire-resistant construction products

The week we unveiled our innovative SafeProof Dome? coincided with the tragic event in Valencia - Spain.

This serious incident highlights the crucial role of fire-resistant materials in the facades and roofs of buildings, complying with the specific regulations of each building and each country.

At Chatron, the safety of our innovative products respects maximum quality requirements and fire resistance requirements are fundamental. That's why we reject the use of materials such as acrylic in our domes, unlike some competitors, and adopt polycarbonate, with its superior fire resistance.

Chatron's new SafeProof Dome? exemplifies this commitment, featuring improved levels of fire resistance, reaching Broof(t1) standards, combining polycarbonate on the exterior with an aluminum connection accessory and an interior flat dome with a layer of laminated tempered glass. It can be used in very demanding buildings, complying with the strictest fire resistance standards.
