alwitra rainwater outlets / emergency pipes are in accordance with DIN EN 1253 and ensure permanent and reliable drainage of rainwater from non-trafficked waterproofed roofs of any kind of construction.

The rainwater outlets / emergency pipes

• are one-piece or two-piece with vertical or horizontal outflow DN70…DN125 and increased outflow characteristics
• have a thermal insulation made of integral PU foam,
• are heatable (optional) and
• have a welding flange for homogeneous flashing to synthetic (EVALON^®) or elastomeric (EVALASTIC^®) roofing membranes or an adhesive or loose/fixed flange for flashing to vapour control layers.

Special two-piece outlets are used for repair works on roof sealings without the removal of outlets.
Rainwater outlets can be installed on trafficked roofs if concealed beneath paviours.
