Tip 1: How to insulate the roof of a house
According to specialists, about 30% of heat lossThe house comes through the ceiling and the roof. Roof insulation reduces these losses. It should only be borne in mind that simultaneously with the roof it is necessary to carry out the thermal insulation of the gables. The insulated attic, which is a buffer between living quarters and outdoor space, allows you to save heat in the cold season and coolness - into the roast.
You will need
- - a heater made of mineral wool with a thickness of 100-150 mm;
- - vapor barrier;
- - wooden slats;
- - a set of construction tools (saw, hammer, ax, etc.);
- - long sharp knife;
- - adhesive tape;
- - fasteners (nails, construction buttons).
Instructions
1
The technology of thermal insulation of the roof depends on the fact,When exactly the insulation is carried out - simultaneously with the erection of the roof or after its installation. When insulating the finished roof, the heater is laid from inside the attic. If the roof lath is a continuous flooring (under a soft roof), attach two or three spacer slats about 30 mm thick at an equal distance from each other between the rafters from top to bottom along the entire slope. Reiki prevent the tight fitting of mineral wool to the crate and provide air circulation between the waterproofing and insulation. This is done in case if, for any reason, moisture gets to the heater from above. When securing the racks, take care that the fasteners do not come out from the other side of the crate, otherwise it will damage the waterproofing. If the crate is sparse (under the slate, steel sheet, etc.), the spacer bars may not be nailed.
2
Lay sheets of mineral wool between the rafters. It is best if the rafters are located at a distance of 580-600 mm from each other. In this case, the insulation sheets, having a standard width of 610 mm, will enter between the rafters tightly and will be held in place without additional fastening. If the step of the rafters is different from the indicated values, cut the minowat into pieces of the necessary size and fix them with slats, nailed inside the rafters. Cut the heater with a long sharp knife along the rake attached to the min wool. Cut the heater with a small margin (10-20 mm) to ensure a tight fit of the sheets of mineral wool to each other and the rafters.
3
Put the vapor barrier on the insulation, fixing it to therafters with construction buttons and scotch tape. The joints between the vapor barrier layers should be glued with adhesive tape. Try to ensure complete leakproofness of the vapor barrier layer, in case of film breaks, tape it.
4
Before you nail to the roof of the inner(cover), ensure a gap between it and the heater. This is done for the same purpose to ensure air circulation and drying of the insulation if moisture gets into it. If the mineral wool is drowned in relation to the surface of the rafters, nail the lining (lining, fiberboard, etc.) directly to the rafters. If the mineral wool is at the level of the rafters or even protrudes from them, then nail to the rafters the slats thicker than the protrusion of the heater protrusion, and then nail the skin to the slats.
Tip 2: How to insulate the roof
The roof is an integral part of any house. It must be strong and reliable, keep warm and protect the housing from unnecessary moisture. Therefore, it is very important not only to properly erect the roof, but also to warm it well.
Instructions
1
To insulate the roof, you can usemodern materials like rigid fiberglass, mineral wool and expanded polystyrene plates, foam concrete or froth glass. All of them have different degrees of thermal conductivity, water absorption, vapor tightness and environmental friendliness.
2
The most popular insulation for the roofis a plate of mineral wool. This material is able to withstand temperatures over 1000 degrees, so in fact it is not subject to combustion. Mineral wool slab differs from other heaters with rather low thermal conductivity and water absorption. In addition, it practically does not undergo deformation and perfectly protects the house of extra noise from outside. Such plates are easy to stack and perfectly dock with each other.
3
To warm the flat roof of the house you can likeexternal, and internal method, in one layer or in two. The external method is much easier to perform. But selecting it, you will need to determine exactly whether the load-carrying structure of the house will withstand the weight of roofing and thermal insulation materials.
4
For the insulation of a non-planar roof, for example, slopingor mansard, you will need to use another technology. When insulating the slope between the thermal insulation material and the roofing, be sure to leave an air gap. Take care also of the presence of a vapor barrier layer, necessary to protect the roof from the vapor penetrating from inside the house. Often it is already built into the heater. In the absence of this layer, you will have to mount it separately.
5
Most often the thermal insulation layer is laid eitherbetween rafters, or on them. But if you need to insulate the roof of a finished house, the insulation will have to be installed only under the rafters. To insulate the attic roof, lay the slabs of thermal insulation material on sloping surfaces between the guides that run from the base of the roof to the ridge.
6
If there is an attic in the construction of the house,used as a living room, only insulate it floor. If the attic is used, be sure to lay the insulation material over the roof slopes.
7
If you want your house to be really warm, think about the insulation not only of its roof, but also of walls, windows, and the floor.
Tip 3: How to insulate the roof with foam
The climatic conditions in the middlewinter period require mandatory insulation of the roof of a private house. Various materials are used for thermal insulation. One of the cheapest, convenient in installation and reliable in operation is the foam plastic. How to properly insulate the roof with foam plates?
Instructions
1
Calculate the required amount of foam plasticPlates to cover the entire surface area of the roof. Purchase plates and take them to the house. When transporting, protect the material from possible physical impacts, damage from rainfall and direct sunlight.
2
Clean the roof of the old backfill. Lay the entire surface with a waterproofing material. Tightly lay on the waterproofing extruded foam plates, not allowing cavities. Pay special attention to the density of alignment of the edges of the plates.
3
Observe the required roof slope - at least 25 ° - to ensure the flow of water from the roof surface into the trough.
4
Place on the foam coating layerhexotextile material, which will protect the plates from the harmful effects of ultraviolet rays and possible mechanical effects, significantly extending their life.
5
Fill a layer of gravel with a fraction of 16/32, about 5 centimeters thick; When calculating the thickness of the layer, consider the strength of the wind. Use paving slab or concrete in the absence of gravel.
6
You can use foam plates to insulate the gable roof and to create an attic, which will increase the useful living space.
7
Attach a geotextile that isprotect the foam from possible harmful effects, to the back of the rafters with the help of wooden rails. With this warming, the thickness of the bar will provide a free ventilated space between the roofing material and the insulation, which completely eliminates the accumulation of condensate.
8
Fix tight plates of foam plastic with a thickness of 7 centimeters, using the same wood rails and galvanized nails. Put a layer of waterproofing mulching film on top of the insulation.
Tip 4: How to insulate the balcony floor
In the conditions of the moderate Russian climate, the issue of the insulation of balconies and loggias becomes especially urgent. Looking in winter on frozen potentially useful meters, willy-nilly you start to think aboutnumerous missed opportunities like a beautiful winter garden or a secluded smoking room. Equally important is the problem of storage of products and stocks. After all, many pickles and jams do not tolerate winter cold - the can glass freezes and bursts. In other words, sooner or later any homeowner comes to the idea of the need for warming balconies.
Instructions
1
However, with balconiesThe situation is somewhat different than with loggias. Warming them is more difficult and expensive. This is explained by the very design of the balconies. They are further removed from the house, more open to precipitation and winds, worse protected. Some balconies on the last floors sometimes do not even have a roof top visor. And yet, such complexity is not a reason to give up the opportunity to get an additional comfortable room.
2
The first and main step in the insulation balconies - this, of course, its glazing. But the second most important step is the insulation of the floor balconies. And on how well and qualitatively it is carried out, the future temperature in this room largely depends.
3
The most common and effective way to insulate floors balconies Today is the flooring of the upper wooden floor. Since usually the concrete floor of balconies and loggias is located slightly below the floor of the apartment, it is possible not to save at the height of the warming floor. The wooden floor is laid on log limes, previously well dried and treated with antiseptic.
4
As a floor covering in mostof cases use a board-lining. If desired, under the wooden flooring, you can pre-lay a floor heater. The most common material for it is glass wool, which has good thermal insulation properties. Also for a greater effect, the wooden cover can be tightened from above with carpet or linoleum. The extra layer will provide additional insulation and create a full impression of the living room on the balcony.
