Isovariant's insulating floor slabs and polystyrene panels offer an excellent 2 in 1 solutioncombining the strength and functionality of traditional floor slabs with superior thermal insulation.
New from Isovariant: insulating floor slabs, a 2-in-1 solution
These hourdis have the same function as traditional reinforced concrete hourdis, but because they are made of polystyrene (EPS), they also act as an insulating screed. So we have hourdi and insulating screed at the same time.
Our rigid floor slabs, made of EPS (and reinforced), offer the following advantages:
Insulating floor slabs are lightweight and easy to install. So there's no need for a crane.
They can provide a wide range of very high levels of insulation (U coefficient up to 0.15 W/m²K).
They are the same price as traditional hourdis, or even cheaper, offering savings of up to 50%.
Rot-proof insulation made in Europe. They provide load-bearing capacity up to 8 metres.
Isovariant's insulating hourdi is available in :
EPS is made up of 98% of mobile air, and it is precisely this characteristic that gives EPS the best energy efficiency. What's more, EPS is highly resistant, insensitive to moisture, clean and safe. This makes expanded polystyrene particularly suitable for insulating floors.
Panel length: up to 8000 mm - 8 metres in one span!
Panel width: 600 mm
Thicknesses from 180 to 580 mm
Insulating value: lambda coefficient of 0.035 W/mK
R-values up to 6.65 W/m²K
In our role as construction consultants, we have researched and found what works best.
A well-insulated home offers incomparable comfort!
Thermo-acoustic polystyrene panels are currently recognised by all the players in the market as the solution offering the best insulation coefficient and the best value for money for insulating floors.
Self-build installation very quick and easy
Various thicknesses and densities for all energy levels, from basic to passive.
Interlocking system, ideal for self-builders, offering savings of up to up to 50%
Rot-proof insulation made in Europe (NL)
Our rigid panels, made from EPS, offer the following advantages:
* Highly insulating * Completely impervious to moisture * Fire retardant * Durable and environmentally friendly * Safe to use * Easy to process and install * Deformation and pressure resistant * Fully recyclable * Does not harm the water table
The Isovariant insulating panel is a slab made of fire-retardant EPS, with a connecting hook.
The unique all-round hook connection provides a watertight side connection, eliminating the need for PE sealing films.
The floor insulation panel ensures continuity in the quality of the thermal insulation of your building envelope, with the walls and roofs proposed in our solutions.
Is polystyrene hard foam harmful? No, because polystyrene hard foam is one of the purest construction materials that meets the most stringent requirements, particularly in terms of compatibility with foodstuffs. Even sensitive foods such as fresh fish can be packaged in polystyrene hard foam.
Polystyrene hard foam has also passed this biological test: the material is used for beehives, nest boxes and breeding tanks for small organisms.
A British institute tested the neutrality of polystyrene by adding 5% of pure polystyrol to the food of experimental animals for two years. As polystyrene hard foam is 97 % occluded air and 3 % polystyrene, this would mean that the animals were fed for two years with one and a half times their volume of ground polystyrene hard foam food.
Result: the polystyrene was eliminated without being digested, and the experimental animals remained in good health.
Similarly, concrete is considered to be biologically irreproachable and ideal for filling in the wounds of old trees.
Quote from a document issued by the Hessian Environment Ministry: "The natural origin of a building material does not guarantee its health neutrality, just as modern plastics are not necessarily unhealthy"..
Neopor® burns like many other materials such as paper, wood, fabric and others...
However, Neopor® insulating formwork blocks are M1-rated, so they are self-extinguishing and do not spread fire.
When Neopor® burns, it releases CO² and CO, water vapour and soot, but no other gases!
What's more, a study carried out in accordance with the DIN53436 standard confirms that the odours, gases and fumes that can be released in a fire are much less toxic than those emitted by fir, pine or cork chipboard.
In construction, Neopor® is not in direct contact with fire, as it is separated from it by the ceiling or plasterboard, which are the materials responsible for fire protection.
Some information about BASF® and Neopor® :
BASF is the world's leading chemical company: The Chemical Company. By balancing economic success with environmental protection and social responsibility, BASF is helping to create a better future. BASF employs more than 95,000 people.
Neopor® foams are silver-grey in colour because they contain granite graphite, which considerably enhances thermal insulation by reflecting infrared rays. Today, Neopor® is well ahead of other materials, even though it is thinner.
The material can be installed during the winter. If night frost is forecast, simply cover the filled wall. The good insulation of the blocks and the warmth of the concrete prevent frost from penetrating to the concrete core.
For suspended elements, the internal thermal insulation is removed and a piece of squared timber is fixed with dowels. All the other fixings can then be attached. Frames are fixed with X-hooks; heavy frames, light wall cupboards and shelves are anchored with standard dowels in the concrete core or with ISO-approved dowels.
The internal walls are just as robust as conventional walls. The concrete core, the internal and external insulation and the approx. 10 mm layer of plaster required inside and out all contribute to this impact resistance.
Isovariant houses are made of solid wood and are just as solid as conventional solid houses. The oldest building with hard foam thermal insulation is almost 50 years old and shows not the slightest sign of ageing. The concrete core is also protected from the weather by the layer of insulation.
