Thermal insulation of concrete floors is a big problem in the apartments on the first floor or in a cottage construction. Basically a floating screed is used to create equality in the loggia. Floating screed is one type of cement-sand screed. Unlike normal ties concluded that the floating screed basis. As a rule it applies in the case where you want the floor insulation. Why is it called the Floating screed. The fact is that between ground floor and most screed paving the insulating material, on which is based, itself a floating screed. And considering that it is not connected with the walls of the room, then it kind of floats on the heat insulator.

Lack of tight coupling with the walls is mainly due to thermal strains in the cement-sand screed cement-sand screed. The first step is satisfied with vapor barrier barriers based on gender. This is especially important if under the floor wet room or a street. Obstruction of moisture is necessary that the moisture may accumulate at the intersection of sex and thermal insulator. Previously all the subfloor put a layer of bitumen mastic. After which the floor is lined with waterproofing material type ruberoyd. Further, on the plank floor heat insulator. When the device floating screed is normally used sheet thermal insulation such as foam or styrofoam.

The thickness of heat insulator calculated according to the desired value of thermal resistance of the floor. The cracks between the sheets liquid foam. Thermal insulator on top of plank paroizolyator of polyethylene or polyethylene foam. Joints vapor barrier glued metallic tape. Creating such a multilayer structure is an important step in the warming of the floor. The upper layer of vapor barrier will pripyatstvovat penetration of moisture in the heat insulator. Learn more about warming. The next step in creating a floating screed is a layer of shock-absorbing packing tape around the perimeter of the floor. This layer will serve as a buffer between the wall and the floating screed. It will not allow floating screed talk directly to the wall. For this layer of the device suitable substrate for laminate. It is fastened to the wall on the liquid nails around the perimeter of the premises. Subsequent phases are absolutely similar to the process unit of cement-sand screed. First fit fittings. In this case, the grid is laid with overlap of 20 cm, linking haywire. The important point is the fact that Mesh should not be based directly on the heat insulator. In this case, after the screed, it stays with its lower side, and it should take place in the middle of the thickness of the floating screed. To this end, reinforcing net put up for some distance from the heat insulator. This is done using a special plastic struts. After laying the grid set the beacons. Installation of lighthouses on the floor, in essence, no different from installing lighthouses on the wall. Lighthouses can be as cement and metal. They are installed so that the distance between the beacon was at 30 – 40 cm shorter than the rule. The side beacons have to defend from the wall approximately 20 cm in the device ties should be applied generally as large as possible, it will achieve the greatest evenness of sex. When the device floating screed using semi-dry mortar. This is because it has the least amount of moisture, which in turn could lead to heat insulator. Solution is spread on the floor and rammed that would eliminate all voids. After that, leveled and overwritten.
