Warming of the floor in the bath

Warming of the floor in the bath under construction deserves attention, despite the fact that the heated air is directed upwards, often seeps into the leaky walls and ceiling. Particularly relevant floor heating in the bath in the middle lane and over the northern regions. Properly made heat insulation will reduce the warm-up areas, will not allow heat leaks, because the contrast of temperatures in the upper part of the steam room and the cold floor in the washing harms the body.

For floors with loosely laid to drain the floorboards (flow-type) thermal insulation is not performed. It is appropriate only for "dry" floors, the water flow which is provided by bias, or gutter downpipe. The dirty water is drained to sump for aeration field and does not harm the floor covering and the underlying insulation.

materials

Expanded polystyrene. This versatile insulation suitable for thermal insulation of concrete floor and wooden base. It is very light, quite hard, well-cut office knife consists of a polymer alloy fine particles, granules. Commonly used for insulation of wooden floors, because it does not absorb moisture penetrating through the board. Gives a minimum of waste, it does not weigh down the structure.

Expanded clay. As thermal properties of the material close to the mineral wool. Its use with wooden floors requires a thorough waterproofing. When used with a concrete floor is difficult to comply with the inclination angle of 10 degrees. For fixation of the bulk material is wetted with weak keramzit aqueous cement solution. Otherwise, a layer of insulation, expanded clay consisting of a mixture with a cement grout, a cement screed is poured.

Mineral wool. This material perform thermal insulation of concrete floor. Due to the hygroscopic material is extremely urgent waterproofing - wet wool fibers partially lose insulating properties.

Foam heat insulator used in the device of floors on joists.

Alternative embodiments are slag and perlite. Origin poured into 30 cm thick, the second - layer is poured between the top and bottom concrete screed.

perlite

As silty volcanic sand, perlite dry ready scatter apart from slight blow. In order to successfully work with him, you want to remove all drafts. In a deep vessel connect two silty material with one part water, waiting shrinkage add cement and a little water. Dry crumbly cake mix knead until plasticity, and then distribute the smooth 10-cm layer at the bottom of the screed. Perlite hardened for 5-6 hours, and then can be filled with a second layer of ties. Sometimes placed on top of the perlite reinforcing mesh and arrange the moisture barrier layer.

Of all the proposed options for the most popular heat insulator in the construction of the baths is polystyrene. It is lightweight, easy to use, easy to measure out the right amount, and the remainder will not be gone too.

Process insulating floors

The main principle of the floor insulation in the bath is the location of the heat insulating material between the two layers of the hard coating, it is necessary and waterproofing.

Warming of the wooden floor

The most convenient way to arrange the insulation during construction. If the wood floor is not leaking, conduct work on insulation can be later completely removing finishing boards. Polystyrene foam consisting of closed cells is optimal heat insulator for a bath and wooden floors. Unlike hygroscopic fibrous materials, polystyrene is not so picky about waterproofing. Excellent keeping warm, it does not increase the weight of the structure.

• Cranial bars, which are necessary for the sub-floor, nailed to the bottom edge of the beam.
• On top of the cranial laid low grade timber boards, smaller than the spacing between adjacent beams.
• Over the first layer cranial floor satisfied waterproofing membrane with a vapor barrier. It covers all the beams and the bottom of each wall 20 cm. Fixed stuff stapled, glued joints vapor barrier tape. The membrane can be replaced with roofing material, glue the seams with mastic asphalt.
• On vapor control layer is laid the second tier of the cranial floor, then - a heater.
• Insulation and top coated with a vapor barrier membrane or bitumen.
• The space around the drain pipe is filled with foam.
• The final stage - laying the finishing floor, trim excess material paroizoliruyuschego, installing baseboards. Between the finished floor and the vapor barrier must remain ventilation gap to the board good been drying.

Thermal insulation of concrete floor

For thermal insulation of concrete floor using styrofoam, perlitobeton, mineral wool, expanded clay, slag foam.

• On rough floor plank waterproofing layer. For this purpose a mastic, rolled material or a mixture thereof.
• Stacked polystyrene foam, mineral wool or expanded clay, on top of this material - reinforcing mesh. The thickness of the heat insulating layer depends on the material properties.
• Outer screed is poured on top of a heater and the valve.
• View the final finish depends on the preferences of the owner.

Waterproofing it makes sense to hold only in the washing compartment and doubles. In the rest room and locker room, you can do without it.
