Yes. Decorative cast iron and brass ventilation grilles of this pattern were widely used in Victorian and Edwardian buildings, and like-for-like replacements are generally accepted by conservation officers for listed building works. We can provide product specifications and material details to support listed building consent applications if required.

The H460 is well suited to Georgian, Regency, and Victorian buildings where a plain, undecorated rectangular hopper is the appropriate choice — particularly listed properties, conservation area buildings, and institutional or commercial buildings in historic town centres. Its clean, restrained form makes it equally appropriate on modern heritage-style construction where period accuracy is required without ornamental detail.
Our cast iron airbricks are available in a choice of finishes including primer and painted options. If you require a specific finish for a conservation project or to match existing ironwork, please call us on 0333 987 4452 to discuss.

We are able to place dates and initials and insignia onto most of our flat faced rainwater hopper heads.
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.
The right size depends on the width of your gutter run and the volume of water you need to collect. The Strayton H42A is available in four widths: 305mm (12"), 355mm (14"), 457mm (18"), and 610mm (24"). As a general guide, wider hoppers suit larger roof areas and heavier rainfall zones. If you are unsure, our team can advise based on your gutter profile and catchment area — call 0333 987 4452.
Our cast iron hopper heads are available in a standard primed and black-painted finish, ready for on-site topcoats. Heritage colour finishes and factory-applied linseed oil paint are available on request. Linseed oil paint is a vapour-permeable, period-appropriate finish particularly well suited to listed buildings and conservation area properties.
The Gothic foliate tracery design of the Ornamental Airbrick provides a good free-flow ventilation area relative to its face size. The open area is comparable to other standard cast iron airbrick patterns. The visual density of the pattern at a distance reads as solid ironwork, which suits formal and decorative elevations without compromising subfloor ventilation effectiveness.
