Wall fireplace insert - you must pay attention

Fireplace inserts can often be purchased inexpensively. But when it comes to walling in the fireplace, many questions often arise regarding materials and techniques. The most important and most fundamental of these answers.

Wall fireplace insert - which stones?

For DIY enthusiasts, Ytong is the building material par excellence. It is easy to transport, easy to cut, has good thermal insulation and is easy to process (also due to its weight).

However, fireplace inserts must not be walled in with Ytong!

It is imperative to use Steiner firewalls, which are highly resistant to heat. Ytongstones, on the other hand, should not be exposed to temperatures above 100° C for a long time.

Therefore only high heat resistant stones should be used for the walling. These are fireclay.

Other options that are also suitable:

  • Lava stones (very popular)
  • clinker
  • special chimney construction panels

Sheath with plasterboard

Incidentally, GK boards can also be used as a simpler variant - they are also permanently heat-resistant (corresponding design of the board).

Important when walling

Already during the production of the masonry must be paid to a variety of things. In addition, there is a generous amount of regulations that must be complied with:

  • the minimum distances to combustible components
  • the installation of adequate ventilation grilles behind the panel in the right places
  • adequate protection of adjacent walls (installation of suitable insulation materials)

The most important rules that can be decisive for a wall are:

  • the state fire regulations
  • the state building regulations
  • the specialist rules of the air-heating engineer's trade (stove-setting trade)

What plaster after the walls?

To plaster the masonry later, it is essential to use suitable plaster. Usable here are only highly flexible plasters, they must also be proven and, above all, be heat resistant. Other plasters may not be used, especially no ordinary interior plaster.

Install spark arrestor plates

Before setting up the walling, you should also think about a spark arrester plate on the ground. Such panels must cover the floor covering at least 50 cm in front of the oven door. Suitable materials for spark protection plates - depending on personal preference - are:

  • Glass
  • Slate or
  • metal

Tips & Tricks

In any case, take care to insulate the walls adjacent to the stove to effectively protect them from excessive heat. With stove kits, these plates are often included if you only buy the fireplace insert, usually not. Then use calcium silicate boards best.
