Warming of the attic floor roof - an important point in the construction and preparation of the house for the cold season. Because it affects the comfort of home. Upper floor requires a special approach in the insulation for the most comfortable stay in this part of the house or cottage.
A detailed article - choose a heater.
Laying waterproofing
Protection of structures in the construction of the building is of particular importance, as prevented from entering water, steam, condensate, or other liquids capable of destroying the structure of the upper part spoiling repairs. How to insulate a roof terrace, let's take a closer look.
Waterproofing is one of the necessary steps to protect the roof. Now on the market there are a variety of building materials, which are reliable, they have different costs and features of their installation.
Waterproofing need to pick up the material under the metal roofing or decking. Its installation is carried out in accordance with the recommendations from the manufacturer, so can avoid deformation of the structure and increase its service life. Select the type of waterproofing must be based on the type "roofing pie". Sometimes it is in two types:
- Warm. Most often it is used in roof areas, where they are living or just used for storing household items. In this case, it provided space heating;
- Cold. Attic space is not used.
Every type of waterproofing requires a certain material. For a cold, a special membrane film that protects from rain and snow. In the case of warm roofs, waterproofing phase involves more complex conditions. It is necessary to provide maximum performance and cold temperature extremes. Here it is advisable to choose the waterproofing, protecting the insulation from the loss of their properties.

Stacking waterproofing has a number of features. For example, if the loft is composed of a metal roof has openings for windows, you will need to ensure that there were no deaf-ventilated place. If a house with a wooden roof, which has a complex structure and many polygonal skates, waterproofing is done with an overlap of 3 cm.
After installing the waterproofing membrane to the type of house, the roof should be closed quickly Bent. This type of waterproofing must be protected from direct sunlight.
Steam, and the rules of its packing
The air tends to concentrate the moisture when the vapor pressure increases. He is trying to get out of the space outside, while collecting the condensate on the cover of a roof. In a humid environment are beginning to develop molds, harmful bacteria, insulation insulation is reduced. In cold weather, the accumulated liquid freezes, and with the onset of warming begins to thaw.
For building materials market offers the following types of vapor barrier material:
- Glassine. He is the most affordable, consisting of a cardboard-based bitumen impregnation.
- Roofing material. Wood, suggesting the assembly.
- Film. Polyethylene (elastic, easy to assemble, is supplied in different layers), polypropylene - strong and durable, as well as different resistance to ultraviolet influence.
- Diffusion membrane. Products that create comfortable conditions for the climate, retain moisture, but at the same time allow the air to circulate.
- Aluminum foil as paroizoliruyuschego member, protects against the penetration of steam removes heat which directs the roof. Foil side is placed on the side of insulation.
Rules are simple self-laying vapor barrier. Vapor barrier layer stacked before or after the arrangement of the roof. Choose the time for assembly work must be based on the weather, the season, the type of materials. The basic rule is rolling roll as it was presented by the manufacturer, and sticking to, stated on the package.
It is not necessary to unwind a roll of insulation, turning it to the side, which is intended for warming. If the film will lay back side, it will pass the water in a larger amount than specified by the technical capabilities of insulation.
Not allowed tension of the film, it should fix so that it slightly sagged by about 2 cm. This is necessary in view of the different behavior of the material in certain weather conditions. Thus, in the rain the film will become larger, swelling, and heat - on the contrary to contract. These fluctuations do not allow it to be deformed, if it is correctly tensioned.
To prevent condensation from dripping into the roof of the pie in the attic vapor barrier is necessary to glue the tape strips. The film is spread with strips overlapping the upper bottom.
thermal insulation
That is the part that is a loft, it cools faster than other areas of the house. It is located just under the roof and the first takes the chill. Because it is necessary to insulate. To insulate the attic, you must choose the right material.
The important point is maintaining the technology and laying thermal insulation attributes. It is necessary to calculate and pick up the thickness of insulation, length and other parameters. When you select should take into account such criteria:
- permeability of the roof;
- Fire safety;
- frost;
- durability;
- roof construction.
The thickness of the insulation to the attic should be calculated on the basis of individual project at home.
How to insulate yourself mansard roof: the procedure works
The correct sequence of actions in the insulation are the key to a successful operation of the roof insulation. The main rule - close contact of the roof elements and insulation. To make the roof terrace suitable for winter use, you need to perform these actions:
- to begin to protect the waterproof film;
- Racks attached with the free placement of insulation;
- the last layer must cover the wooden beams, so that through them did not pass the cold air;
- If there are empty spaces, they must blow with foam;
- also need to install and another layer of vapor barrier material.
In the event of the through holes during the execution of the works, they must be sure to close.
Insulate the roof outside his own hands
For thermal insulation on the outside of the roof need to use special materials for dense plates type. Choose items that differ moisture resistance. It is advisable to make lagging with the facade of the house. It reduces the need to beat the board, which would not give to crawl poet down. The board should be equal in width and thickness of material used.
Note that all wood should be treated with antiseptics, fire retardants, special solutions for external works.
Before starting work on the insulation, make sure the space under the roof ventilation system is made.
To make the attic warm, and it does not have problems with excessive moisture, you must strictly follow the instructions for the work. If the roof is at the same time the walls of the attic floor, with a broken line design, the work of the algorithm is as follows:
- The lower part is the inner lining. This can be drywall or paneling.
- Further mounted crate.
- First vapor barrier is laid, and then heat-storing material. The thickness of the insulation depends on the place of residence. Enough for the middle band of 200 mm, for colder regions of this parameter should be above.
- Superdiffuznaya placed on top of the membrane. After it leaves a gap for ventilation.
- The last stage is laid roofing material.
Sami plates for thermal insulation must be expanded in a checkerboard pattern. Carry out work necessary, starting from the bottom. The film also stretches for waterproofing bottom, moving up, given the overlap of 10-15 cm. Formed the border need to glue adhesive tape. This is to protect against leaks and condensation.
Such a layer cake will allow you to save heat, creating additional space for living.
Thermal insulation of the inside
Process attic insulation inside can be divided into two parts:
- Base. When the insulation is carried out during construction. It uses lightweight insulation, if in the future will not be used as an attic.
- Additional. When is the additional installation of a heater with the creation of high-grade living space.
When it becomes necessary to carry out a mansard roof insulation structure inside the most common problem in this case it is the small thickness of the rafters.
Main article about work with walls.
To fix the problem, you need to create an additional crate or cage. Further work is being done in several steps:
- Creating and kontroobreshetki crates of wooden slats.
- To the rafters stretched twine or thick thread throughout the crates area that will hold the material during operation.
- Building a metal frame that is mounted to the rafters with staples.
- We put the heater on all the area of the roof.
- The expandable metal braces, they will additionally hold the material at the time of finishing.
Roof insulation of the attic is the most popular method for attic. The material desirably selected based on mineral wool. Sometimes ecowool or used polyurethane foamIn this case, steam is not required.
But the waterproofing must be conducted, regardless of the insulation material. For this purpose a special membrane that can pass the steam, not missing a moisture. Between roofing and waterproofing material needed for the ventilation gap, the thickness of which varies between species roof. He will produce excess steam from the heater to the top.
What is better to choose a heater for the mansard roof
In total there are 3 main types of heaters for mansard roofs that are in demand:
- The liquid foam insulation is easy to use, well-suited for self-insulation of the attic;
- Mineral wool - is able to pass better evaporation;
- Extruded polystyrene foam. It is resistant to temperature and elevated humidity.
Liquid foam insulation - it is a new type of insulation, which is made on the basis of different materials with the latest technology. It is divided into several types: a ceramic composition, liquid wool and Penoizol. Each of them has its own characteristics and advantages, but combines the convenience of their application. Using a special technique, liquid insulation can be quickly and accurately fill in any, even a very large space.
It will be interesting - insulation of the attic floor.
Mineral wool - fiber material, made of metal slag and small remnants of basalt and carbonate parody. In the construction market, you can find several varieties of this material:
- glass wool;
- Slag;
- Stone and basalt wool.
This material uses the deserved respect and thanks to a number of positive qualities:
- Fire resistance. Alloys made of incombustible silicate rocks;
- Resistance to chemicals and microorganisms. Mineral wool does not enter into chemical reactions with other substances, which allows its use in areas of chemical production. Also, the heater does not like rodents and fungus, so it can be used in food processing facilities, as well as health care and child care centers;
- Low water absorption;
- Eco-friendly material, safe for humans;
- Durability. With proper installation of the service life of the material is about 70 years.
Extruded polystyrene foam is dense, porous material. Bubbles enclosed inside contain air, which is great at trapping heat. Compared to mineral wool have a thermal conductivity of the material is lower, but it has a water vapor permeability of zero. The advantages also include its durability. Through tight connection between molecules bending strength varies from 0.4 to 1 kg per cm2 .
The better insulate the inside roof terrace
The warm roof, it's up to the owners. It should take into account factors such as the design of the house, its structure and characteristics, the estimated temperature, financial capacity, etc. Also be aware of the advantages and possibilities of materials for thermal insulation to make all right.
Polystyrene (EPS)
This material has a relatively low price, which justifies the quality. Because polystyrene is considered to be the most popular option of warming mansard roofs. Its main advantages are:
- low thermal conductivity;
- absence of water absorption;
- low weight material;
- convenient for a form in the form of plates.
Ecowool
Thermal insulation using ecowool It has the following advantages:
- It does not shrink over time;
- does not require a vapor barrier, it outputs a pair of outwardly;
- It provides a vapor barrier in remote places;
- environmentally friendly;
- affordable price;
- guarantees soundproofing.
These materials are more usual during the thermal insulation of the roof.
How to spend a mansard roof insulation foam inside
In the presence of non-residential space under the roof insulation need only overlap. But when it comes to the living room, it will require serious work. For attic insulation foam It fits best. Mounting foam is carried out in several stages:
- Wooden floors are treated with antiseptics. All slots are sealed hermetically zapenivayutsya or silicone adhesive;
- The entire area is coated waterproofing layer;
- Make the crate of wooden beams, a step in the slab width;
- Is laid over the entire area foam while closely monitoring the occurrence of cracks or gaps which may pass the cold air. Spread plate in a staggered manner in two layers to the lower joints are closed top;
- On top of insulation vapor barrier is laid;
- At the end of the whole structure is closed finishing material.
Before working necessarily calculate the necessary quantity of matter, in view of a double layer coating.
Thermal insulation of the roof - a crucial step in building a house. On it depends the heat of tenants. Because you need to pick up that material, which is suitable for a particular type of roof, ensuring her protection. To avoid unnecessary costs, we must calculate the cost of materials in advance.
