Insulation of Precast Elements
Insulation of the elements from outside
In this case the insulation is directly layed on the pallet in the works. After this the reinforcement is placed and the complete element is concreted. By doing this a fix connection between concrete and insulation is created. At the site the parts are joined together without any additional expenditure of labour for the insulation. The obtained insulation values are known to you out of the practiced building.
Insulation between the shells of the double wall
In this case first the reinforcement is placed on the pallet and then the element is concreted. After the concreting process the insulation is pressed into the still wet concrete. The free space between the braced girders is filled and the element is stored for hardening.
This element is the first shell of a double wall. In the further production process the second shell is produced and by turning the first shell a double wall is created. Here the insulation lies protected between the two concrete shells.
Advantage: The insulation is protected against damages and weather conditions. With a wall, 300 mm thickness, and an insulation thickness of 80 mm there is, according to DIN 4108, a K-value of 0,4 W/m² K.
