More about Alumasc Cast Aluminium Half Round Guttering

Cast aluminium half round guttering combines the recognisable smooth curve of traditional roofing systems with the advantages of aluminium construction. It provides a timeless look often required for older homes and conservation areas yet does not suffer from the corrosion and heavyweight issues linked to cast iron. The internal profile supports reliable water drainage and minimises blockage risk. Installation benefits from lighter components and secure fixings that help maintain alignment throughout the gutter run. A wide choice of colours and sizing options allow for careful matching to the property’s original style. When installed with cast aluminium downpipes and other accessories from Alumasc it supports a complete heritage appearance with improved durability for the long term.

FAQ

Why is half round the most common gutter shape?

It’s simple, versatile and provides efficient water flow for most roof types. Easy to install and compatible with circular downpipes.

What lengths do they come in?

Standard 1.83 metre (6 ft) sections are typical and align with traditional cast iron spacing for easy retrofit.

Can I join half round aluminium to existing plastic gutters?

Yes, using transition connectors, though full replacement is usually preferred for a consistent look.

Do they need expansion joints?

Not usually on domestic runs. Leave a 3 to 4 mm gap at joints for thermal movement in hot or exposed conditions.

What is the best bracket to use?

Fascia brackets are suitable for most applications; rise and fall brackets for open eaves. Alumasc’s cast brackets are strong and match the finish.

Can they be installed by one person?

Yes. Aluminium is light enough for one person, although long runs are easier with two for alignment.

How do I touch up cut ends?

Use Alumasc’s colour-matched paint and apply two thin coats before sealing.

What finishes are most popular?

Black and anthracite remain the most popular, but heritage greens and lead greys are increasingly used on listed buildings.
