Why zamokaet minvata: how to insulate ceilings in the bath and does not rot overlap
You go to the bath, looking at the ceiling, and there... One corner already black from the damp. Chimney dirty smudges. In general, the outer wall of the mold has gone. One season, second, third, and fourth with the characteristic crunch down flies overlap. And all this is the result of stacking thin film stocks.
In the "trough" water will not collect
Bath - a strategic object so that it all prefer to build their own hands. Do not trust anyone. And it turns out. Only about insulation remembered at the last moment.
Spread out in the attic of the membrane directly on the beams. Placed in the "trough" insulation, and top insulation film is tightened. The result is always the same - the moisture from the steam enters the beam (and if on the lower layer of the membrane, and then in a heater), thus can not exit upwardly. Materials get wet and rot over time.
The correct solution is just one. Around the bottom contour under the beams stretch the insulation film (not membrane). Fasten it kontrobreshetki bars, which serve as guides for the lining. Between the beams laid mineral wool. Closing insulation does not need anything. If you have to go from the top - the stele of the board.
Melt the bathhouse - all steam left in the steam room. It does not let up film. Dry insulation and beams are half a century.
How to insulate an attic and not overpay
Controversy over the thickness of the insulation will live forever. I will not persuade anyone. To understand the essence of the most stubborn, I will bring the situation to absurdity. In conclusion, a small life hacking.
Winter, on the street minus thirty. Attic in a bath at a slightly warmed slightly, and I want to wash. Nataplivaem hot oven and ran into the steam room, as long as all the heat through the roof flew away. Mineral wool, of course, frozen and tread condensation on the ceiling. As they say - he "burst into tears". Over time, there is mold and rot.
When the heater is small, "Ceiling crying" even in small freezer. When the thickness of the insulation of large overlap withstand Siberian frost. For normal insulation of the ceiling in the bath, it is necessary to lay mineral wool 250-300 mm. The most scrupulous may calculate heating equipment themselves.
I understand that just blew your budget for the construction of baths. If you go into it often, you can save a little on the insulation and wood to overpay. 150-200 mm thick mineral wool does not allow condensate to frost 15-20 degrees. The truth will have to burn a little more than firewood. At the same time, to avoid mold, after bathing open the door and the window to ventilate the bath.
