Harmer Roof Insulated Graduated Vertical Spigot Outlet, available with a Dome or Flat grate, in sizes 75mm & 100mm. The Harmer Roof Insulated Vertical Spigot outlet comprises a rigid foamed polyurethane body 22mm thick and a 495mm square elastomeric bitumen connecting membrane fused to the body of the outlet. This membrane bonds to three- layer felts, torch-on roofing and hot asphalt.
Harmer Insulated Outlets are for use where the requirement is to eliminate condensation forming on the underside of the outlet due to cold bridging mainly in metal deck warm and inverted roof installations. Alternative connecting membrane specifications are available for bonding to PVC, EPDM, TPO and EB roofing.
The outlets are supplied with a black polyamid domical grate as standard. An aluminium flat grate is also available, but should be used only in inverted roof constructions where the outlet is covered by paving on Harmer Modulock or Uni-Ring raised supports. An optional electric heating element moulded into the outlet body can also be supplied.
