The wooden and cement formwork blocks are manufactured at IsoblocFixolite's Italian branch.
Since the 1960s, over 600,000 homes in Europe have been built using wood-cement blocks. Fixolite and its branch Isobloc account for almost 5% of this market.
The many advantages of insulating wood cement blocks
CERTIFICATION
Fixolite and Isobloc blocks have undergone a battery of tests and have all the necessary certificates for fire resistance, thermal and acoustic insulation, mechanical resistance, environmental protection, etc.
THERMAL INSULATION
Thanks to the low specific weight of the wood fibre and the graphite polystyrene insert, the Isobloc formwork block offers excellent thermal insulation, resulting in significant energy savings.
ACOUSTIC INSULATION
Thanks to their considerable mass, Isobloc formwork block walls offer excellent acoustic insulation, making them the ideal material for the construction of buildings with high requirements in terms of acoustic insulation and comfort.
ECONOMIC
Because it can be installed so quickly, this 3-in-1 block is very economical. 3 in 1, because it combines formwork, thermal insulation and acoustic insulation.
HEAT ACCUMULATION
The high specific weight of the concrete core provides advantageous energy storage times and therefore considerable thermal inertia.
Structures with thermal storage walls prevent the rapid cooling of interior rooms and avoid long heating times. This avoids thermal shocks and, consequently, over-frequent start-ups of the heating and cooling systems. The result is very high efficiency and a feeling of living comfort.
considerable.
NO THERMAL BRIDGES
The dry installation of the formwork blocks (without cement mortar) and the vaults in the same material means that there are no thermal bridges at all, preventing the annoying formation of mould and condensation in the structures.
ECOLOGICAL
Isobloc blocks are made from a homogeneous mixture of mineralised spruce chips and Portland cement. The manufacturing process does not alter the insulating properties of the wood, and generates little waste because it is fully recyclable.
SELF-BUILD
The ease and speed with which these blocks can be used make them an excellent candidate for self-builders. Thousands of private individuals have already built their homes using these blocks, which are proving to be an excellent plaster base.
PERMEABLE / BREATHABLE
The highly porous surface of the Isobloc formwork block allows water vapour to escape.
natural condensation to flow outwards through the transverse walls of the block, which represent around 30 % of its surface area.
FIRE RESISTANCE
The Isobloc formwork block wall is coated on both sides and has a fire resistance of 180 minutes at a temperature of 1200°C.
In terms of reaction to fire, the Isobloc formwork block is certified to fire class M1.
PARASISTIC
The construction system is suitable for seismic zones and complies with the strict standards imposed in Italy (LLPP of July 2011).
The Isobloc range
All the blocks are made from the same type of wood, sourced locally, and Portland cement. They are 50 cm long and 25 cm high. This means that 8 blocks are needed for 1 m² of wall.
Classic blocks
(H blocks)
This block is the most economical and offers good performance.
Highly insulated blocks
(HI blocks)
This patented high-insulation block provides high-performance external thermal insulation (ETI) with a total absence of thermal bridges.
Special blocks and partition blocks
Isobloc blocks meet your most specific needs: partition blocks, pilasters, risers, edges, acoustics, etc.
Floor tiles
Floor tiles provide thermal and acoustic insulation.
The Isobloc service
The Fixolite and Isobloc team will provide you with ongoing support for the construction of your building.
A detailed plan
Once the order has been confirmed, our architect will calculate your requirements in terms of different blocks. A detailed assembly plan (and AUTOCAD files) is then provided.
This colour plan identifies the different models: normal, angle, pass, half, cut-out, edge, etc.
Corner blocks, pass blocks, etc. do not affect the price per m² of the blocks. However, if they are cut to size (for an extension or edge block), a price supplement of around 40% will be applied.
Under certain conditions, we take back unused pallets after the job has been completed.
Isobloc is in BIM
The 3D BIM blocks are available to professionals for use during the design stage.
BIM or Building Information Modeling is a 3D digital construction process in which information relating to each element of the project is managed and shared by the entire construction team throughout the building's lifecycle.
BIM provides the professionals involved with precise information about the physical and functional components of a model. This enables smarter, faster and more sustainable planning, design and construction.
On BIMobject®, you can find ISOBLOC blocks in all common design formats such as AutoCAD, ArchiCAD, Sketchup, etc.
H blocks vs HI blocks
What are the advantages and disadvantages of the two block models?
| Criteria | Block H | HI block | Explanation |
|---|---|---|---|
| | Internal insulation (H block) vs. external insulation (HI block) | |
| Thermal insulation |  |  | Total absence of thermal bridges for the HI block and +30% of insulation (for the same thickness of block) |
| Acoustic insulation | | | Wood cement combined with concrete provides excellent acoustic insulation. |
| Fire resistance | | | It is the façade rendering that provides the fire resistance of the HI block. |
| Implementation | | | The H block offers better plaster adhesion without primer, and the blocks are easier to align. Always pour concrete 1/2 storey at a time using self-levelling fluid concrete. Never vibrate the concrete, as this could alter the alignment of the blocks. |
| Perspirant | |  | The HI block is not breathable. A VMC is in all cases necessary or even compulsory for a class A passive house. |
| Acoustic comfort | | | The inner wall is a continuous wall of wood-cement and acts as a high-performance acoustic panel. |
| Cladding | | | The HI block is not suitable for cladding weighing more than 30kg/m² or for cladding with anchors. |
