| Perfimur flashing cover |
|
| Description |
|
| PERFIMUR cover panels are manufactured through a continuous manufacturing process using the most modern technologies. The sandwich panel is formed by an outlined metallic face wall, inside which a core of polyurethane foam works as a thermal insulating. This provides it with a great solidity thanks to the excellent adherence of polyurethane to metallic parameters, due to the special treatment that steel sheet received. |
|
 |
| This panel fastening is made through screws hidden by the flashing, created for such purposes. Besides, this flashing guarantees full water-resistance because it avoids the entrance of water, even by capillarity. |

 |
|
| Steel |
|
| PERFIMUR uses high-quality pre-lacquered steels. Steel galvanised sheet Z225 by zinc immersion (Sendzimir process) SIN EN 1 0142 and DX51D quality of 0.6 mm thickness and pre-lacquering covering depending on needs (polyester, Plastisol, PVDF, etc.). It is also possible to use other sheet thickness following a previous study. |
