Harmer Insulated outlets are used to eliminate condensation forming on the underside of the outlet due to cold bridging, mainly in metal deck warm and inverted roof installations.
Applications, Materials & Installation
- Harmer Insulated outlets are used as an alternative to metal outlets in metal deck warm and inverted roof installations
- They eliminate the risk of condensation forming on the underside of the outlet due to cold bridging
- Electrically heated outlets are also available and are used in areas of permanent shadow and north facing buildings
- The high insulation value of the Harmer outlet body reduces heat loss. This one-piece outlet body provides a completely watertight connection between the roof membrane and the rainwater pipe
- The flange connection to the flat roof membrane creates a fully watertight connection and the domical grate permits the free flow of rainwater
- Vertical, horizontal and graduated vertical spigot configurations are available along with the option to include a thermostatically controlled heating element
Materials & Finishes
- Harmer Insulated outlets have a rigid polyurethane foam body, fused with an elastomeric bitumen flange. Alternative flange specifications are available for PVC, EPDM, TPO and EB roofing membranes
- Insulated outlets are supplied with a black polyamide domical grate as standard. Aluminium flat grates are available for use in inverted roofs where the outlet is covered by paving on raised supports
- A polyurethane extension piece, with bonded connecting flange, caters for alternative insulation thicknesses
Installation & Maintenance
- Harmer Insulated outlets are available with a flexible connecting membrane fused to the outlet body to seal to the bituminous or single ply roof waterproof membrane. An alternative to the connecting membrane is a clamping ring for sealing specialised single-ply membranes into the outlet mouth
- They are easy to handle and fix and require minimal routine maintenance
