Heath Aluminium Doors

Visit our Cardiff Showroom

We are proud of our showroom, and our customers tell us that we have the best showroom for windows and doors in Cardiff and South Wales.

When you visit our showroom, you will be greeted by friendly staff who will make you feel welcome. It’s on an industrial estate so there’s plenty of parking.


You will usually be greeted by Annie or Max.  The boss is never too far away so I’m sure you will run into Miall at some point too.

You will never feel under pressure. Come and browse for as long as you like. We are here to help, not badger you.

Showroom Virtual Tour

For your convenience, we have produced a video for you to get an idea of the types of displays in the showroom.

There’s no substitute for coming in to meet us though. Your home improvement purchase is important and it’s worth making sure that you see the colour and the textures, especially if you choose a grain or metallic finish.

We have made many changes in the last year and included more products. This includes the Equinox Conservatory Tiled Roof System.

We are proud to have won the ‘Showroom of the Year award’ by National Fenestration Awards.


Colin Jackson CBE

We had the pleasure to welcome Welsh sprint and hurdling legend Colin Jackson CBE. The former World champion & Olympic silver medalist visited the team at Heath Windows to officially open our new showroom. Our showroom exhibits our range of windows and doors where anyone can come and take a closer look at the products that Heath Windows have to offer.

Colin has been a loyal customer for many years and is a supporter of local businesses.
