Coping and capping is often used interchangeably,

Secret fix copings are a unique type of coping that has been designed to fit snugly on top of a parapet. To mount the coping onto your wall and conceal the fixing, you will need to use a special clip system which is concealed behind the coping itself.

The secret clip can easily be attached using mechanical fixing without any unsightly fixing visible from the ground or from the roof.

A parapet wall is a low wall that runs along the roof edge to protect the roof from damage. It’s usually made of concrete or brick, but can also be made of other materials.

Parapet walls are used in residential and commercial buildings, particularly those with flat roofs where safety is an issue. Their design depends on their purpose – they may be decorative or purely functional.

Several materials can be used for capping a parapet wall. The most common materials include:

  • Concrete
  • Aluminium
  • Brick
  • Sandstone
  • Granite
  • Marble

You may have seen aluminium coping/capping on the top of a building. It can be used on both new and existing buildings.

A clip-fixing design is a method of securing the coping to the wall by using clips that are hidden behind the capping. The clips are fixed to the wall with a hidden fixing.

No visible fixings are a benefit for the following reasons:

  • Clean aesthetical look.
  • If no fixings are showing, then there is no need for maintenance on any fixings such as re-painting or replacing screws etc., which can be time-consuming and expensive.

The thickness of the aluminium coping depends on the width of the parapet wall and the architects specification. 2mm is the usual thickness, however there are occasions where 3mm thick aluminium is used.
