Insulated Guttering

Q. Why insulate a gutter ?

A. If the gutter is located in side the main fabric of a building or roof covering and the rest of the building is insulated, then the gutter must also be insulated or else the dew point of the warm internal air will be reached when it meets the gutter forming condensation. This will cause drips of water, poor thermal performance of the building and reduction of gutter life.

The Elite Insulated Gutter is a market leader with specification second to none. This gutter can be made from a variety of materials for both weather side and internal finish. We can manufacture insulated gutters in almost any shape and in sections up to 8000mm and girths up to 1500mm The most popular material used on the weather side of the gutter is membrane coated steels similar to those used for flat roofing. These membranes are bonded to a galvanised steel with a paint coating on the reverse side. Depending on specification and requirements the gauges used are 0.8mm steel with 0.6mm membrane or 1mm steel with 0.8mm membrane and 1.2mm steel with 1.2mm membrane.

A selection of other materials can be used including all PVC Coated Steels, Aluminium, Stainless Steel and Paint Coated Steel.

The most common material used on the internal finish of the gutter is a plain white lining enamel, although other finishes can be used including PVC coatings, PVDF or Powder Coating depending on aesthetic effect required or in the case of an aggressive internal environment Eliteform also manufacture all of the accessories required for an insulated gutter including:Stopends (including insulated stopends) Outlets (in galvanised steel and membrane, specials made on request)Hopper head receivers for high volume storm water removal. Weirs and overflow systems. Factory formed corner and tee units. The insulation that we use for the core of the Elite insulated gutter is a Polyisocyanurate (PIR) foam which has significant fire performance. Should (PIR) be subject to a fire the foam forms a surface char, this helps to insulate the underlying foam and reduces further involvement of the foam in a fire and will only begin to degrade around 350 oC. This insulation has a number of Irish Agrement Board certificates and is acceptable by the Association of British Insurers (ABI). Insulation thickness varies from 20mm to 100mm depending on the required U – Value. The life of any gutter system is determined by a number of factors including:
