Translucent roofs can be made with different types of tiles. According to Roof Scapes, the Top Rated Roofing Contractor in Richardson, TX, the most common translucent tiles are those made of polycarbonate, polypropylene, fiberglass and glass. For places subject to impacts such as falling branches, for example, the ideal is the polycarbonate tile, which offers greater mechanical resistance. The material also features protection from UV radiation and heating; it can be 30% cheaper than glass, and its aluminum frame is lightweight. The problem is the noise when it rains.
To avoid excessive heating of the place, it is recommended to group up to four translucent tiles at a time. In addition, ideally, it should be combined with fiber cement tiles – a material with low thermal conductivity.
Difference Between Materials
The polypropylene tiles are also lighter, but not as impact resistant as polycarbonate. They are effective against bad weather such as humidity, corrosion, mold and attack from chemical agents. In addition, the material allows transmission of 70% of light, has protection against UV rays, and its price is more affordable when compared to polycarbonate tiles.
In turn, fiberglass tiles have a more affordable price than other varieties, being more used in low-budget projects. Like polycarbonate and polypropylene, they also make the project lighter. Its disadvantages are the low levels of thermal and acoustic insulation, in addition to the lack of treatment against UV radiation. The material expands and, therefore, is prone to cracking.
On the other hand, glass tiles, with tempered or laminated processing, offer better translucency and also more impact resistance when installed with reinforcement against shattering. In addition, glass has greater durability and better acoustic performance. On the other hand, it is the highest cost option and requires structures that support higher loads as it is heavier.
