What better to do screed?
mixes for screeds for underfloor heating can be taken as a wet process (cement-sand mixture) and for the organization of semi-dry method (also cement laying, but with the lowest water content). Dry screed for the organization of water underfloor heating is not like , becausemoderate moisture resistant gypsum fiber sheets of moisture, yet scared.
required elasticity cement base can be given by adding a screed mortar plasticizer.Thanks to this special emulsions density screed increases, less
IMPORTANT! Please note: heating pipe or cable, whether it is an electric floor or water, it must be well surrounded this solution with the possibility of thermal expansion.
screed thickness over the warm floor
screed thickness depends on the type of screed, as well as the anticipated loads on the floor. example, in private tie layer may not exceed 45 mm, moreover, that the overall height of the screed floor heating, considering hidden in cement communications is 65 mm.
Liquid ties - a more expensive material, but the price is justified: screed floor heating takes less time, it is easier tie in all respects.Poured floors stronger usual because occupy less height: only 25 mm on top of underfloor heating with an overall height of 45 mm screed.
IMPORTANT! solution for tightening over the warm floor is prepared in a ratio of 1: 4.Composition screed with sand fractions 0.8 mm, cement 200-250 kg / m³ of concrete and water.
screed thickness over water underfloor
to correct pipe 12 MB screed must have a height of about 60 mm, the height of the entire structure for a pipe 17 MB - 65 mm (water without floor screed is about 20 mm in height).
IMPORTANT! before a screed for underfloor heating wet, consult with experts: the weight of the structure may result in the order of 150 kg / m: not all floors can withstand this extra load.It is also important to choose a screed for underfloor heating so that the material screed provides good thermal conductivity, and the heating system could work in the usual mode.
competent screed installation: expansion joints
Since the subfloor will be expanded under the constant influence of heat necessary to avoid cracking, scratching the screed, as well asdeformation of the heating elements themselves sex.To do this, provide mobility ties: the walls are placed compensatory band equip expansion joints.
mentioned compensatory band - it otrez of soft polyurethane foam applied to the foil. foil put on the side of the strip insulation as a kind of seal.The strip is mounted around the perimeter of the room.
As for joints, they equip:
- near the front door;
- at the floor area of over 40 square meters space;
- when at least one of the room's walls longer than 8 m;
- at a ratio of length and width of the room as a 1: 2;
- indoor complex shape.
Insulation under screed
If your plan was to heat the ceiling is, neighbors or warm exterior walls, take care of the insulation layer, placing it under the screed.Thermal insulation screed or additional insulating material will keep up to 25% more heat in the room.
screed for warm water floor and the floor of the electric: after completion of installation work
After laying the floor heating system and screed when the repair is almost over, it is important to gradually warm upfloor.The floor is heated after the established technology, the regulatory period for setting the screed before laying the finishing floor.
temperature of the heating pipes should be increased gradually.In all the time necessary to isolate the screed heating from sunlight and influence draft.When warming up their hands, and not by the order of services masters, be extremely careful blemish at this stage may damage your system.
