The company Green Isologic based in Verviers, in the Belgian province of Liege, has designed insulating shuttering blocks that are perfectly suited for constructions without thermal bridges and they ensure perfect sealing.
The insulating shuttering blocks designed by Green Isologic provide high thermal performance that allows constructions to fulfil the passive standards without any difficulty. This is an effective solution for all those seeking ecological, energy-efficient buildings.
Green Isologic's insulating shuttering blocks have two Neopor walls (expanded polystyrene). The inner wall is 5cm thick and the thickness of the outer wall can vary from between 5 and 20 cm. It is the outer wall of the block that provides the high energy performance. Between these two walls is a 15 cm space which will be filled with a rich concrete mix. This part will be the load-bearing component of the construction. The two walls are firmly joined together with 6 braces.
| Standard | Wooden framework | EPS | Neopor | Insulation factor |
|---|---|---|---|---|
| Standard – EU 2011 | 40cm | 35cm | 25cm | u=0.26 W/m²K |
| Low-energy house | 45cm | 40cm | 30cm | u=0.18 W/m²K |
| Passive house | 50cm | 45cm | 35cm | u=0.14 W/m²K |
| Zero-energy house | 60cm | 50cm | 40cm | u=0.11 W/m²K |
Thanks to the concrete in the centre of the block and the double insulation, the shuttering block provides an exceptional sound insulation of 41 decibels.
With its concrete skin, the insulating shuttering blocks provide high mechanical resistance. Moreover, they can be used in the construction of earthquake-resistant buildings.
Isologic shuttering blocks also provide fire protection.
The shuttering blocks are water-repellent and rot-proof. To optimise their water-tightness, Isologic blocks are covered with a hydraulic coating. The blocks are then overlaid with the chosen covering material.
All our different types of insulating shuttering blocks can be seen below (straight blocks, corner blocks, closures, lintels, etc.).
