The flood causes great damage to the home. The frameworks of the LGS have an undeniable advantage over the wooden frame in case of flooding, because the wooden frame will necessarily have to be dried after getting wet. To process wood when it is saturated with moisture is a useless thing.
But let's look at another question. What happens with insulation in a frame house with classical wireframe technology with one wall and wools?! Wool insulators and moisture are two incompatible things. In the case, if wool insulation is damaged by the water, we must necessarily replaced old on a new insulation. This means that you need to remove the skin of the house, remove the wet insulation - go to the state of the "bare" frame. This is a complex, expensive and emotionally unpleasant process for the owner of the house.
That's why the Double Wall System of LGS is the perfect combination of steel and concrete, which is not afraid of water. This is an ideal solution for quickly and reliably eliminating the severe consequences of flooding. Of course, you can use different types of concrete in the Double Wall system: foam concrete, aerated concrete, polystyrene concrete. But we are adherents of polystyrene concrete.
~ The use of polystyrene concrete reduces the cost of the foundation.
~ Polystyrene concrete has high strength characteristics, has high sound insulation.
~ This is the only kind of lightweight concrete that has plasticity. The flexural strength of polystyrene concrete is 50-60% of the compressive strength, in concrete this parameter is 9-11%.
~ It has improved frost resistance, low operating humidity, improved chemical and biological resistance.
~ Polystyrene concrete has the optimum steam and air permeability for enclosing structures, it is non-toxic.
~ Polystyrene concrete has stable characteristics when prepared under construction site conditions, which can not be said about foam concrete and aerated concrete.
~ Polystyrene concrete 300 mm thick = thermal conductivity about 1.5 meters of brickwork.
~ Polystyrene concrete in the Double walls LGSF does not interfere with air exchange, ie the walls are able to "breathe", and due to high vapor permeability - to regulate the humidity of the air.
~ About polystyrene concrete it is possible to tell safely: "on water the brick floats". He swims in the water and does not sink. moisture absorbency of polystyrene concrete only 4% (foam concrete 14%, aerated concrete 70%).
Recently, more attention is paid to the comfort of living in the building. For such parameters as vapor permeability and thermal inertia, polystyrene concrete corresponds to wooden materials, and the necessary resistance to heat transfer can be achieved by varying its thickness.
