  FIXOLITE insulating shuttering blocks are made up of non-acidic wood shavings of even texture, which have been treated to remove dust, then mineralised and agglomerated with Portland cement. The elements are moulded and compacted by vibration. After curing, they are gauged to ensure they are square on all 6 surfaces. Where required, expanded polystyrene is added in the cells to provide additional thermal insulation. The blocks are then palletized and stored in the open air.  
     
     
     
       

FIXOLITE insulating shuttering blocks have been used successfully for more than 45 years in foundation brickwork (with a waterproof barrier applied, just as with conventional building blocks), as well as for external and internal walls.

The FIXOLITE construction system is covered by an “Avis technique” approval certificate, No. 16/91-237. It is also approved in Germany under Approval No. Z-4-2-111.

  
 
   
The system has already been used in the construction of :
detached houses
apartment blocks (up to 30 storeys)
industrial, commercial & agricultural buildings, etc.
hospitals
shed for noisy or dangerous machinery
swimming pools
sports halls
 
     
     
 
 
       
Load-bearing Structures
Once it has been finally cemented in position, FIXOLITE block has the same load-bearing characteristics as concrete, with the additional advantage of insulation.

Thermal Insulation
The hollow structure of the wood-fiber concrete provides excellent thermal insulation characteristics resulting in significant energy savings.

Heat Storage
The solid mass of concrete into the cells of the blocks stores the heat and slowly releases it again. This prevents thermal shocks, ensures that the heating system is not switched on and off too frequently and prevents wide temperature fluctuations. The results are greater economy and thermal comfort.

  

 


Acoustic Insulation
Once the wall is filed with concrete, it has a very dense mass which leads to good acoustic insulation. The system is thus particularly suitable in noisy installations, in hospitals, blocks of flats, dividing walls, etc.

Active Breathing Structure
The aerated nature of the material allows water-vapour to diffuse freely.
The transverse surfaces in a wood/cement agglomerate material make up around 20% of the total wall surface.
This “active breathing” zone ensures that internal humidity is rapidly dispersed to the exterior.

  
       
 

Fire Resistance
A 20 cm thick wall coated on both surfaces will withstand fire for more than 6 hours in accordance with ISO 834 standard (temperature of 1200°C).

Fire Reaction
FIXOLITE blocks are classified as non-flammable to Category M1.

  
   

Rot-Proof
FIXOLITE blocks will not rot and are impervious to rodent or termite attack.

Surface Finishes
The structure of FIXOLITE blocks will accept all conventional types of finish.

Exterior :
Conventional base and common or single-coat cast.
Cement base with synthetic resin decorative top coating.
Jamb bricks or blocks.
Decorative concrete panels.
Small slabs, brick sheets, ceramic tiles, etc.
Direct covering (without lathwork) with slates, aluminium panels, plastic
  sheeting, shingles,
woodwork.
   
Interior :
Untreated or painted surfaces (good airborne sound
  absorption).
All kinds of sheeting and panels.
Plaster and similar coatings.
Cement base coat with a thin decorative top covering.
Ceramic on top of cement base coat.
 
       

One Single Operation
By positioning FIXOLITE blocks the load-bearing structure and insulation are placed at the same time.

Quick to Install
The blocks are placed in position without any mortar (except for the first course). They are simply positioned, one on top of another, like children’s building blocks.

  
 
   

Lower On-Site Costs
FIXOLITE blocks are simple to fit, very light (one block weighs about 16 kg) and quick to install (4 blocks per m2). They can also be cut easily and will accept screws and nails without using special tools. They therefore reduce on-site working times and manufacturing costs.
No special labour is required.

  
     
     
     
       

The first course is set on a mortar bed and carefully spirit-levelled.

The following courses are placed dry (without mortar), one on top of another, alternating the joints.
Any reinforcing rods, etc., are put in place at this stage.

  
Special blocks enable any type of layout to be achieved :
cut-outs of 25, 50 and 75 cm (pre-cutout in the blocks)
doorways and windows lintel brick
right angles
blocks can be cut in the workshop or on site for the insertion of lintels, ends of
  flooring, etc..
they can be easily cut to form :
  - round shapes
- special angles
- semi-circular or other types of lintel
- gable tops
- round, triangular or other shapes of window.

Water piping, heating circuits and electrical wiring, etc., can all be positioned within the cavities of the blocks before concrete is poured, or by cutting channelling in the walls afterwards.

 
       
 

Applying the concrete
The concrete can be applied :

by crane or by shovel, if the blocks are being
  concreted progressively,
by crane or by pump, where entire walls are to be
  concreted, or where walls and floors are to be formed
in one operation.
 
   

Where the concrete is to be applied in several stages :

do not fill the blocks completely, fill to within 5 cm of the top.
clean the surfaces of the blocks after the concrete has

A typical concrete mix will be
800 litres of fine gravel (4/16)
400 litres of sharp sand
350 kg of cement (this may vary, depending on the loads involved)
 
       

When linking with structural walls, the surfaces in contact should be split, so that concrete is continuous within the two walls. Horizontal reinforcements, placed every 2 courses and bent at 90°, will ensure a good joint between two walls.

External and internal walls are made up with insulating blocks which are stacked dry (with the exception of the first course, which should be set on a mortar bed and levelled) and then filled with concrete. Various thicknesses and versions are shown in the drawings.

Blocks are made up of non-acidic wood shavings of even texture, which have been treated to remove dust, then mineralised and agglomerated with Portland cement. After curing they are gauged to ensure they are square on all 6 surfaces. Where required, expanded polystyrene or another type of insulation - to be specified - may be added into the cells.

The specific gravity of the material is 510 kg/m3. Production is checked by an official laboratory and samples are taken at least once a month. The blocks are rot-proof and non-flammable to Class 1. The fire resistance of a wall which has been coated on both sides is more than 6 hours (Tests carried out in accordance with
ISO 834 - 1973).
