Description

Alumasc Harmer Insulated is a range of outlets based on a rigid polyurethane foam body, completely eliminating any possibility of condensation forming on the underside of the outlet due to cold bridging.

Outlets have an elastomeric bitumen connecting membrane fused to the outlet body, for bonding to built up bituminous membranes, torch-on roofing and hot asphalt. Consult manufacturer for details of alternative connecting membranes for other roofing types.

The Harmer Roof Graduated Vertical Spigot outlet is an economy version of the Harmer Roof Insulated Vertical Spigot outlet. The thickness of the foamed polyurethane body is reduced from 22 mm to 11 mm.

Graduated Vertical Spigot outlets are particularly suitable for:

  • Roof constructions which allow only a shallow outlet bowl.
  • Cold roofs, where the formation of condensation on the underside of the outlet within the ‘cold’ roof void is unlikely.

The Harmer Insulated Graduated Vertical Spigot roof outlet connects to PVC O-ring socketed pipe directly, or with heat-shrink adaptors where necessary. Connections may also be made to HDPE pipework using appropriate couplings, or to socketed and socketless cast iron pipework using couplings, adaptors or cold caulking as appropriate. Each outlet is suitable for connection to either 75 mm or 100 mm pipework. When connecting to 100 mm pipe, the 75 mm section of the spigot should be cut off. This can be done on site with a fine-toothed saw.

Product Options

Grate:

Domed or flat (suffix …/F) grates are available. Flat grates are specifically for installation under paving slabs set on Harmer Modulock or Uni-Ring raised supports. They enable rainwater to drain away under paving slabs on inverted roofs.

Accessories:

– Extension piece:

Extension pieces are used in warm roof constructions where the waterproof membrane occurs above the level of the roof deck. Suitable for insulation thicknesses of 50–120 mm. Extension pieces are available with a choice of connecting membranes. Consult manufacturer for details.

– Terrace grate:

Designed for terrace-type applications exposed to pedestrian traffic. The aluminium alloy Terrace Kit consists of a circular fitting ring which is positioned over the mouth of the outlet. The terrace grate then rests on the ring and can be adjusted up or down to ten different heights, from 30–90 mm, to suit varying thicknesses of insulation and surface finish.
