What sizes does the telescopic brass rooflight opener come in?

What sizes does the telescopic brass rooflight opener come in?

The Brass Rooflight Hand Winder Opener – Telescopic is available in 150mm, 250mm, and 300mm sizes. The telescopic mechanism provides flexibility to accommodate varying rooflight positions and throw requirements. Throw: 165mm.

Is a chrome rooflight opener compatible with Lumen Rooflights?

Is a chrome rooflight opener compatible with Lumen Rooflights?

Yes. Both the satin and polished chrome telescopic rooflight hand winder openers are compatible with Lumen Rooflights and most timber-framed skylights. Call 0333 987 4452 if you need to confirm compatibility with a specific model.

Do your steel brackets have a protective coating?

Do your steel brackets have a protective coating?

Yes. All our mild steel brackets are supplied in either silver or black zinc plate. This coating protects the metal however, both will need painting prior to installation.

We have chosen to use zinc plating for two reasons; firstly that it is a more environmentally friendly than galvanising and secondly that it does not block up the threaded part of the rise and fall cups in the way that galvanising does.

What finishes are available on your cast iron hopper heads?

What finishes are available on your cast iron hopper heads?

Cast iron hopper heads from Tuscan Foundry are available in Standard Black (a factory-applied primer and topcoat finish) and Heritage Colours. A linseed oil paint finish is also available, providing a vapour-permeable, historically authentic coating that is particularly appropriate for listed buildings and conservation projects. Full finish specifications are available from the team.

What building types is the School Board Cast Iron Airbrick suited to?

What building types is the School Board Cast Iron Airbrick suited to?

The School Board Airbrick is suited to Victorian and Edwardian terraced housing, mid-century school buildings, civic halls, public baths, and converted institutional buildings. Its plain square-grid face matches the utilitarian aesthetic of late-Victorian construction and is also appropriate for new heritage-style builds in conservation areas.

Is a brass rooflight opener suitable for use on a listed building?

Is a brass rooflight opener suitable for use on a listed building?

Yes. A polished brass finish is historically appropriate for period buildings and is generally acceptable to conservation officers for listed building projects. If you are unsure about the specification requirements for your project, we are happy to advise — call 0333 987 4452.

What building types is the Regent Cast Iron Hopper Head No.1 (H1) suited to?

What building types is the Regent Cast Iron Hopper Head No.1 (H1) suited to?

The Regent H1 is well suited to Victorian and Edwardian terraces, listed commercial buildings, civic and institutional properties, and ecclesiastical buildings where a traditional funnel-form hopper is architecturally appropriate. Its multi-faceted tapering body reads as period-accurate on Gothic and classical building types alike, and it is a commonly specified choice for conservation and listed building projects across the UK.

How does the ornamental pattern affect ventilation performance?

How does the ornamental pattern affect ventilation performance?

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.

What is the Brass Rooflight Opener Handle 1520mm used for?

What is the Brass Rooflight Opener Handle 1520mm used for?

The Brass Rooflight Opener Handle 1520mm is a pole-operated handle designed for manual rooflight opening mechanisms. It is suitable for use with Lumen Rooflights and compatible timber-framed skylights, and is particularly appropriate for period and heritage properties where a brass finish is specified.
