The G46 moulded cast iron gutter is a larger and more decorative version of the common ogee profile. Known as the G46 or No.46 moulded pattern, it shares the elegant S-curve cross-section of the ogee but with a deeper section, more pronounced moulded detail, and significantly greater drainage capacity. It is found on Victorian and Edwardian country houses, manor houses, civic and institutional buildings, hotels, large churches, and any substantial period property where the roof area and rainfall load demanded something beyond the standard common ogee.

This section is 1829mm (6 feet) in length, manufactured in solid cast iron to BS 460:2002. Available in two profile sizes: 125mm (5″) and 150mm (6″). Supplied in primed or factory black finish as standard. The socket-and-spigot joint connects sections in a run, with union clips and jointing compound completing the watertight seal.

Accepted by conservation officers and listed building authorities as the appropriate heritage material for period properties where the G46 moulded pattern is the historically correct profile. The G46 is a pattern-specific gutter — angles, outlets, stop ends, brackets, and clips must all be from the G46 range, as fittings from the common ogee range are not compatible.

Where an existing G46 installation has failed in part, the section can be matched precisely and supplied for a repair-and-replace specification, preserving the character of the original system without full replacement.

Part codes: G4301, G5401, XG4301, XG45401, Moulded 46DC, G830. For specification support or a project quotation, call 0333 987 4452.

My builder has calculated out our heating requirement in each room of our house in BTU’s. Can you tell me what BTU’s stand for, and is this different to KW.

My builder has calculated out our heating requirement in each room of our house in BTU’s. Can you tell me what BTU’s stand for, and is this different to KW.

BTU stand’s for British Thermal Units. This was the old (Imperial) measurement for heat in connection with plumbing. Although BTU’s is a term still commonly used within the heating and plumbing, the industry is now going over to KW’s Kilowatts.

Can the louvre airbrick be used to replace an existing cast iron ventilation grille?

Can the louvre airbrick be used to replace an existing cast iron ventilation grille?

Yes. The Louvre Airbrick is dimensioned to standard brick course openings and is suitable for direct replacement of worn, broken, or missing original cast iron louvre grilles. If you are unsure of the size required, measure the opening in the brickwork rather than the existing damaged grille.

Is the Ornamental Airbrick appropriate for a Grade II listed building?

Is the Ornamental Airbrick appropriate for a Grade II listed building?

Yes. The ornamental foliate pattern was widely used in Victorian construction and is appropriate for Grade II listed buildings and conservation area properties. Its decorative character is often preferable to a plain pattern on prominent or formal elevations. We recommend confirming the pattern with your conservation officer as part of any listed building consent application.

What sizes and weights are available for the Ornamental Airbrick?

What sizes and weights are available for the Ornamental Airbrick?

The Ornamental Airbrick (OAB) is available in three sizes: 225mm × 75mm (2.8kg), 225mm × 150mm (4.1kg), and 225mm × 225mm (5.8kg). All sizes have a uniform depth of 75mm, making them consistent to install across a subfloor ventilation course.

What building types is the Ornamental Airbrick suited to?

What building types is the Ornamental Airbrick suited to?

The Ornamental Airbrick is suited to Victorian villas, bay-fronted terraces, Gothic Revival institutional buildings, church halls, and civic buildings where decorative ironwork is part of the architectural language. It is also appropriate for listed buildings and conservation area properties where the airbrick is on a prominent elevation and the ventilation grille is expected to carry decorative character.

What finishes are available on cast iron hopper heads?

What finishes are available on cast iron hopper heads?
