FAQ

Frequently Asked Questions

Can the X-BLOCK also be cut?

No. The X-BLOCK modules are hollow inside and can no longer be used if they have been cut.

Are there X-BLOCK stones with different dimensions?

No. The stones only have the dimensions 20 x 20 x 8 cm.

Can the X-BLOCK also be used to form curves?

A curved installation made of X-BLOCK stones is not feasible without further work. What you can do is arrange several elements within timber frames (or similar) and form these into an angled curve.

Is the X-BLOCK also suitable for use outdoors?

The X-BLOCK has primarily been designed for use indoors. Nevertheless is can be used outdoors. The blocks have been tested for heat and cold but they do not provide the insulation protection required of windows. It is essential that you use silicone instead of conventional sealing profiles if you plan to use the blocks outdoors. The X-BLOCKS must have adequate room for expansion as the material changes in the cold and heat.

Can the X-BLOCK be used as a shower partition?

Yes but there is an important difference to when it is used in dry areas. In wet or damp areas, a neutral cross-linked wet/damp room silicon should be used instead of the sealing profiles that guarantees that no damp can penetrate into the wall.

What is the load capacity of X-BLOCK walls?

The load capacity of X-BLOCK walls is 80 - 100 kg / m.

Can a door be incorporated into an X-BLOCK wall?

Yes. If you wish to fit a door into an X-BLOCK wall, then you should firstly fix a square timbered construction or similar with the dimensions 80 x 30 mm (depending on the depth of the architrave). The architrave with the door can then be fixed to this as usual.

Can the X-BLOCK be used to build "around corners"?

Yes. However, this is only possible if a 80 x 80 mm block of wood (or aluminium tube) is fixed to one side of a finished element. The next element can then be fitted in the right angle.

At how many points does an X-BLOCK wall have to be fixed?

The fixing always depends on the size of the respective structure. Fundamentally, however, for the stability of a wall, it should be fixed at at least two points (i.e. to the floor and to a side wall).

Are X-BLOCK blocks UV-resistant?

Yes. The X-BLOCK is made of the same material as is used for the front covers of lights on cars in the automotive industry.

What fire protection classification of the X-BLOCK?

Fire protection requirements, particularly in connection with exhibition stands, are becoming ever more stringent. The X-BLOCK is classified as fire protection class B2, however in the past this has not always been regarded as being sufficient by some exhibition organisers. As a result of this, regrettably certain projects could not be completed using X-BLOCKS.

This fact motivated us to find a solution:
now a metal strut is incorporated into the expansion joints of X-BLOCKS that have a spacing of 20 cm. This produces a metal grid that prevents the wall collapsing or toppling over in the even of a fire. This construction results in fire category B2 is now accepted so that all projects can be completed.

Can the X-BLOCK also be lit?

Yes the are are various methods for lighting X-BLOCK partition walling systems:

• conventional light tubes can be incorporated into the expansion joints (point lighting)
• fluorescent tubes can backlight the wall
• fibre lighting system: a light projector (outside of the wall) is used, either with or without a colour wheel. The colour wheel allows the light to pass through the joints and changes the colours. If the wheel is stopped at a certain colour, then only this colour is visible. The light passes through the fibreglass threads or cables that are laid into the expansion joints during installation.
  
  

How can you build a complete X-BLOCK element into an opening in a wall?

The X-BLOCK element is preferable pre-assembled. The finished element can then be fixed into the opening in the wall with timber rabbets.

What is the sound insulation of an X-BLOCK element?

The sound insulation of an X-BLOCK is comparable to that of a plasterboard wall.
