Frequently asked questions
1 – What are Telite's tiles made of?
Telite’s tiles are manufactured from dual-layered sheets of modified HDPE / acrylate. The inner base is made of HDPE, specially developed to be used in roofs (a compound of HDPE + impact modifier). As to the external layer, it’s made of acrylate, which protects the tiles against UV radiation. In addition to these components, Telite’s tiles feature also an internal rubber mesh, which provides the final product with resistance and flexibility at the same time.
2 – How can I cut Telite's tiles?
If you must cut Telite’s tiles or their complementary parts, use a power saw, hacksaw, sawing bow or jigsaw.
3 – Will Telite's tiles lose their color easily under sunlight action?
No. The external layer of Telite’s tiles has been designed with a proper UV protection, including also color fixatives. The technology developed by our company provides the product with extended lifetime and longer color stability, when compared to conventional tiles.
4 – Will the tiles parch or break with time?
Telite’s technology gives flexibility to the tiles, allowing their exposure to the weather for many years without parching or breaking, well beyond conventional tiles.
5 – Being made of HDPE, will they make much noise in case of heavy rainfall?
On the contrary, HDPE acts as a buffer and fully prevents sound transmission.
6 – How can I clean Telite's tiles?
If needed along the years, cleaning is very simple: you can use only water and a mild soap for this purpose. It’s worth reminding that all precautions must be taken to avoid slips or falls in roofs of any kind.
7 – Can I paint Telite's tiles?
If you want to modify the tiles’ color, you can paint them with a proper epoxy paint.
8 – A hole has been made in the wrong place during the tiling procedure. How can I cap it?
To cap holes in HDPE tiles, we suggest color silicone for outdoor areas. Keep in mind, however, that the silicone will require maintenance on a yearly basis or whenever needed.
9 – Due to the imperviousness of the tiles, can condensation occur indoors, in those regions with high humidity levels?
Yes, due to temperature difference between the tiles and the environment.
10 – Being lighter than conventional ones, can Telite's tiles fly off in case of heavy winds?
As with any kind of roofing, the action of heavy winds can indeed remove some pieces. On the other hand, this can be avoided by fastening the tiles correctly. We offer proper fastening kits, which are able to relieve any tensions that can appear during windstorms, thus preventing the tiles from flying off. You must follow the instructions of this manual regarding installation and spacing between props.
11 – Can I walk on roofs made of Telite's tiles?
Yes. Telite’s HDPE tiles can withstand a vertical load up to 1.2 kN, which means an average human weight of 120 kg. They show a flexible behavior to deformation, as with other kinds of plastic parts. Additionally, the material used in Telite’s tiles is one of the few plastics with “memory” – that is, after partially deformed, it will return to its original shape after the load is removed. Therefore, you can walk on the roof, but always follow the safety instructions during such procedure.
12 – Will Telite's tiles warp with time?
No, as long as the spacing between props is done according to the instructions. Made of HDPE (a compound of HDPE + impact modifier), Telite’s tiles feature resistance and flexibility at the same time.
13 – What is the best way of storing and transporting Telite's tiles up to the construction site?
Place them in a flat surface, without exceeding 50 units in each stack. To assure a good-looking roof, carry them with care, thus avoiding scratches and damages.
14 – Can they be used in chicken farms and other animal breeding sites, where the indoor environment must be kept refreshed?
Telite’s tiles have a good performance when comes to thermal comfort, if compared to cement fiber or zinc tiles, for instance.
15 – Must I install a thermal blanket under the tiles?
Telite’s HDPE tiles don’t offer full thermal insulation. If the project requires such full insulation, you must really use a thermal blanket, and make other provisions for such purpose. In this way, the use of HDPE tiles will be one of the actions for project execution, and not only the final solution.
16 - As telhas são porosas? A exemplo das outras coberturas, elas deixarão “passar” um pouco de umidade devido à porosidade?
As telhas Telhas Telite são feitas de PEAD. Não são porosas nem deixam passar nenhum tipo de umidade, pois são impermeáveis e estanques. Porém, em épocas mais frias, pode acontecer, em ambientes de varanda, o chamado “orvalhamento” na face interna das telhas devido à diferença de temperaturas.
17 – Will I need expert workers to install the tiles?
The installation of Telite’s tiles is very simple, and follows the same basic rules of the other kind of tiles. You won’t need expert workers to install HDPE tiles, as long as the instructions of this manual are followed. Their benefits go well beyond the needs of final use of the roof, making the installation work easier: they are easy to assemble, much lighter than the others and very practical.
18 – Can I replace pieces from a cement fiber roof with HDPE tiles?
No. In addition to having a different spacing between props, when compared to other roofing types, the profile of HDPE tiles doesn’t allow a perfect fit with other materials. Besides, with this kind of replacement, you will have no right to the use technical warranty of Telite’s tiles.
19 – Are HDPE tiles being used in other countries?
Yes. The use of HDPE for roofing occurs in Asia and Europe already, but is still unprecedented in Brazil, with the pioneering of Telhas Telite.
20 – Are these tiles standardized?
To assure a healthy and fair competition in the market, along with safety for consumers of HDPE tiles, the profiles and colors are standardized, and the suppliers of the production cycle are properly audited by the Brazilian Association of Plastic Tile Companies (Abitelha). There is also a technical initiative (Sinat) – which, after the recommended proof tests, oversees the technical behavior of products for the safety of consumers and manufacturers.
