alwitra rainwater outlets

The thermally insulated alwitra rainwater outlet S (vertical) provides the connection to a vertical drainage pipe.

• Stable: made of highly impact-resistant polypropylene (PP).
• Comprehensive: can be used for four different diameters (DN 70, DN 100, DN 125 and DN 150)
  • Included reducer 125/110 allows direct connection to DN 125 pipes (OD 125 mm) and DN 100 pipes (OD 110 mm)
  • Optional reducers and adaptors for drainage pipes DN 70 (OD 75 mm) or DN 150 (OD 160 mm)
• Permanently waterproof: flashing against the roof waterproofing with a screw ring. In combination with an oval gasket and a corresponding flashing collar, a reliable and long-term waterproof connection is easily established between the roof waterproofing and the rainwater outlet itself.
• Flexible: unproblematic flashing also against other vapour control sheets installed in classic warm roofs instead of waterproofing membranes. Professional and safe installation. Thermal insulation layers can be bridged by an extension piece.
• Clean job: combined leaf guard/gravel trap included in the scope of delivery.

The thermally insulated alwitra rainwater outlet W (horizontal) provides the connection to a horizontally laid drainage pipe. It is available in two different sizes:

• W 125 for connection to DN 125 pipes (OD 125 mm).
• W 75/110 with low overall height for connection to DN 70 pipes (OD 75 mm) and - with included adaptor 75/110 - to DN 100 pipes (OD 110 mm)
• Stable: made of highly impact-resistant polypropylene (PP)
• Permanently waterproof: flashing against the roof waterproofing with a screw ring. In combination with an oval gasket and a corresponding flashing collar, a reliable and long-term waterproof connection is easily established between the roof waterproofing and the rainwater outlet itself.
• Flexible: unproblematic flashing also against other vapour control sheets installed in classic warm roofs instead of waterproofing membranes. Professional and safe installation. Thermal insulation layers can be bridged by an extension piece.
• Clean job: combined leaf guard/gravel trap included in the scope of delivery.

All alwitra rainwater outlets are optionally available with electrical heating (230V AC).

• Hot: factory-fitted heating system consisting of a silicone heating mat
• Smart: a built-in thermostat protects against overheating
• Easy to connect: connection to the 230V AC power supply by means of a thermostat without using transformers
• Sustainable: energy-saving thermostat with outdoor temperature sensor. For turning on the heating only when it is really necessary.
• Simple: only one thermostat, regardless of the number of heated rainwater outlets installed

alwitra extension pieces are used for bridging thermal insulation layers of warm roofs and are available in three different lengths - depending on the thickness of the thermal insulation:

• Extension piece 200 for thermal insulation from 50 - 200 mm
• Extension piece 400 for thermal insulation from 50 - 400 mm
• Extension piece SL in individual lengths according to customer specification
• Stable: made of highly impact-resistant polypropylene (PP)
• Flexible: easy flashing against the roof waterproofing with a special screw ring. alwitra extension pieces are compatible with all alwitra rainwater outlets and provide backflow-proof connection by simply inserting them into the rainwater outlet.
• When used in combination with alwitra rainwater outlet S or SH, the extension piece usually requires no cutting to length. For roofing membranes EVALON® or EVALASTIC®, a corresponding flashing collar is included in the scope of delivery
