BDL is the ideal solution for producing skylights or glazed roofing, which can be either flat or curved. The system, which comprises an engineered multiwall panel in extruded polycarbonate, provides good thermal insulation and excellent optical and mechanical properties. The panels slot together simply and effectively with the aid of specific polycarbonate profiles. Where required by the project’s structural load, these can be upgraded to aluminum or steel profiles.

The special clip-together fastening system does not involve making through holes in the polycarbonate. This enables long stretches of roof to be produced and makes the product really easy to install and consistently reliable when it comes to keeping water out.
