The brick-clad Faststack® Chimney System is a prefabricated range of ‘working’ and ‘cosmetic only’ chimneys, available in a range of standard designs. They comprise of GRP (Glass Reinforced Plastic) cores which are clad in traditional facing materials thereby complementing the properties on which they are to be installed.

  • Flues are compact and easy to install, saving both room space and time on-site.
  • Faststack® Chimneys are fixed to the roof trusses and the built in flashing channels ensures a waterproof seal.
  • Hearths and fireplaces require no extensive foundations or supporting masonry to support the chimney.

For the best match all of our chimneys can be made using any brick, stone or render from your project.


Ibstock Kevington was the first to gain BBA Certification for its brick-clad chimneys, giving you total confidence for in excess of 25 years.


Any roof, any pitch, any location on the roof.

  • CGMA quality assured.
  • BBA certification with a service life in excess of 25 years.
  • Full installation instructions and fixing pack included.

NHBC Technical Advice: The NHBC recommend that only chimneys that are made to CGMA standards or third party accreditation are to be used.

Venting Options
Many of the chimneys in the range are available as fully working units, suitable for venting both Class 1 & Class 2 appliances. These chimneys include a pre-installed Twinwall flue system selected to suit the particular requirements of the project. Once on site the system is simply linked to the existing flue system using appropriate couplings.


The Gable End Ridge chimneys are designed to allow the brickwork to continue from the gable wall into the chimney unit.

In situations where the chimneys are not located directly over the gable wall, the Mid Ridge design can be used.

Faststack Mono Pitch chimneys can be located anywhere on the roof pitch.

The Parapet chimneys are suitable for installation directly over a Parapet wall. These chimneys can be designed to accommodate a variety of heights and widths and include a cut out area to allow the chimney to be seated traditionally on the parapet wall.


Fire protection at the junction of a separating wall to a pitched roof is usually achieved by the provision of mineral quilt to fill gaps between the wall, roof underlay and roof covering, across the full width of the wall. It is essential that the fire protection is not compromised.

To prevent the spread of fire, the dummy chimney should be provided with a fire resistant base so as to achieve the fire protection.

Any gaps between the base of the chimney and the separating wall should be filled with a non-combustible material in a similar manner to the fire stopping provided between the party wall and roof covering.

One way of achieving this is to adopt the detail shown in Figure 1. It shows the typical fire stopping provided between the wall and roof covering continuing under the dummy chimney. It is important that the method of fire protection provided under the dummy chimney links fully with the fire stopping provided between the wall and roof covering. The secondary weatherproofing provided by the roof underlay should be maintained by either continuing the underlay under or dressing it around the chimney.
