Gutter Systems

Insulated Valley Gutters

Steel, aluminium and membrane can all be used to manufacture an insulated gutter. Valley gutters form part of the overall roof envelope and therefore require to be insulated to the same value as the roof.

A typical insulated gutter will consist of an upper skin (galvanised steel, aluminium, stainless steel or membrane), a lower skin which is sometimes internally visible and manufactured from a steel white liner to match the rest of the internal roof and a rigid PIR insulation core.

Depending upon the design these gutters are fully walkable, as the core should be 80mm thick to help achieve an overall roof U-values of 0.25W/m2k. Insulation properties are normally expressed as thermal conductivities. This can be translated as a thickness of insulation, which is required to meet the correct U-value as specifi ed in the Building Regulations. The table below shows the different thickness of most common insulation with typical K- Values, required to meet these requirements.

Accessories - Stop ends, weir overfl ows, outlets, junctions, T-pieces, corners and sumps are all available and factory assembled.

Downpipes and Accessories - To suit the application there is a variety of aluminium down pipe sizes available from 50mm to 200mm, square and round. Aluminium is corrosion resistant, light and can be polyester powder coated to provide an attractive finish. The quantity and size can be calculated using the CRM Gutterflow software.
Swannecks or offsets can be produced in any angle and length combination to suit site conditions. Rodding eyes, collars, square to round connectors and brackets are available to suit site requirement.
