Description

Aluminium roof outlets, designed to fit within the existing outlet and pipework of the roof which is being upgraded. Because of minimal disturbance and the ease of fitting, it represents a very cost-effective and efficient solution to flat roof upgrading.

Features and benefits:

  • Increases flow performance at the outlet location, regardless of pipe diameter downsizing. There is no need to remove the old rainwater outlet.
  • The outlet body is manufactured from diecast LM6 aluminium silicon alloy to BS EN 1706, and incorporates a welded 300 mm aluminium tailpipe.
  • The tailpipe, cut to the required length, is simply inserted through the existing outlet, into existing pipework, and sealed by means of the IKO Roof AV special multi-fin pipe seal.
  • This seal creates a watertight junction between existing pipework and the gulley tailpipe. The outlet body’s wide fixing flange incorporates concentric grooves which enhance the bond with roofing felts or asphalt.
  • Includes an LM6 aluminium silicone clamping ring, which also has a ridged under-surface for an improved bond with roofing membranes.
  • Two sealable ports in the outlet body are designed for injection of polyurethane (PU) foam to fill the void between old and new outlet.
