Long gone are the days when the concept of a warm roof meant only a simple canopy protecting from rain and wind. The current roofs are a whole complex consisting of many layers, each of which is made using a special technology using advanced developments and the latest technological materials. We will talk about this in our article.
Builders often call the roof construction the playful word patty. However, as you know, in every joke there is some truth. Modern roofs can contain many layers of different materials, each serving a different purpose.
Among the main layers that provide insulation of the roof of a private house, we can note, first of all, layers of hydro- and heat-insulating materials.They provide protection from external influences and any bad weather.
Remember! A well-thought-out and properly assembled multi-layer roof will easily help you survive the autumn rains and winter cold.
In addition to insulating materials, the roof structure is made up of various reinforcing materials, as well as structures designed to provide additional ventilation.
The free circulation of fresh air can be very important in order to prevent the accumulation of water remaining from the resulting condensate between certain particularly dense layers.
Such structures are most often made of natural materials, primarily wood. It is wooden partitions and rafters that provide proper ventilation, but at the same time do not greatly burden the overall structure.
In addition, wood is a convenient and environmentally friendly material, which also plays a role in its use.
Reinforcing layers are inserts made of solid and reliable modern materials. It can be gravel, concrete tiles, or any other material that performs the necessary functions. The purpose of these layers is to protect more sensitive materials from mechanical stress.
Note! Parts made of heavy materials are heavy, so try to strike a balance between lightness and reliability.
And, of course, the crown of the entire pyramid is, of course, the external roofing.
Depending on the desire and capabilities of the owners, this can be anything:
- various types of tiles;
- slate;
- modern coatings made of lighter and more comfortable materials.
The purpose of this layer is primarily aesthetic in nature, so its color, material and texture are completely dependent on the tastes of its owners.
Insulating layers
The arrangement of a warm roof primarily depends on the insulating materials used. There are many ways to achieve the desired result.
The choice of one or another material depends entirely on the specific needs and environmental conditions of life.
For some, good protection against water and moisture is important, but for some, the main threat is the incessant winds. Thus, the specific set of required layers can vary considerably from house to house.
- Waterproofing. Layers designed to protect against excessive moisture. Heavy rain, snow, and fog all pose a raw threat to both the material of the building and the people inside. Various waterproofing materials also prevent the penetration of water into the interior of the structure, thereby increasing its operational properties.
- Vapor barrier. This type of insulating materials is designed to provide reliable protection against a variety of fumes, as well as prevent the appearance of condensate on various surfaces and layers.
- Noise isolation. This type of isolation is used much less frequently than the previous ones, but it also has its adherents. Noise-absorbing materials in the layers of the roof structure serve to suppress particularly loud environmental sounds and provide a quiet, comfortable indoor environment.
- Thermal insulation. The most comprehensive category of roof insulation materials.It is the provision of proper thermal insulation that is the key function of many "pies". The range of modern thermal insulation materials is very wide, so decisions on the use of specific measures must be made on a case-by-case basis.
Types of thermal insulation
A variety of materials for room insulation allows everyone to choose the option they need, based on their own vision of their needs.
You can choose simple and economical options roof insulation from the inside, and you can provide reliable long-term protection against any threat using the latest materials based on the latest scientific developments.
- Roof insulation with expanded clay has been used everywhere for quite a long time. Expanded clay is a lightweight building material made from natural baked clay. Outwardly, it has the appearance of round or oval granules. This form allows you to combine the flexibility and versatility of bulk materials with the thermal insulation properties of clay.
- Polyurethane foam is a more technologically advanced heat-insulating material that belongs to the category of foam-filled plastics. Roof insulation with polyurethane foam is much easier than using expanded clay, but it has its own characteristics. This material is installed in the form of large solid slabs, but the material itself is quite soft, so it needs additional hard reinforcement in the roof structure.
- Foam boards are a very new solution in the field of thermal insulation. Plates made of this material perfectly retain heat, while being flexible and compact.Such layers are much thinner than their competitors, which allows the use of space in the roof structure much more efficiently. Due to its features, foam roof insulation is gaining more and more popularity.
- Roof engtktybt with standard foam.
Layer arrangement
An important role is also played by the location of the various layers in the roof structure.
Therefore, before assembling it, you need to properly consider the order in which the various materials are arranged, based on their functions and features, then do-it-yourself roof insulation will be optimal.
- Waterproofing layers should be at the very top and at the very bottom of the entire structure. The top one serves to protect other layers from the effects of precipitation, and the bottom one to delay evaporation from the room.
- The vapor barrier layer is next in importance after the waterproofing layer, but is used only in cases where the situation suggests a risk of high humidity. These include, for example, the roof of the bath. The vapor barrier layer serves to additionally protect sensitive parts of the structure from excessive fumes.
- Thermal insulation layer. It is located in the heart of the structure and is securely protected from all sides from any possible threats. Made of special materials, this layer is perhaps the most important component of the entire roof, so special attention is paid to its reliability and safety.
- The wooden parts serve to maintain the shape of the entire roof structure, as well as to ensure proper ventilation of some layers to prevent the accumulation of excess condensate. The rafters, which make up the frame of the entire roof and the basis for laying all its layers, deserve special attention.
- Stone embankments and concrete inserts serve to strengthen individual parts of the roof, as well as to protect them from unwanted mechanical influences. The use of these design solutions is optional and should be subject to a rigorous feasibility assessment, as such details can significantly increase the overall weight of the roof, leading sooner or later to a possible risk of collapse.
- And finally, roofing. This layer is the final and securely covering all the others. Its main purpose is to provide the roof with a pleasing appearance and give it completeness, while hiding less aesthetic design details from the eyes.
Thus, in order to carry out successful and effective work on the insulation of the roofs of your home and other buildings, you need to have a number of specific knowledge, including:
- a clear representation of the structure of the layers of modern roofs;
- understanding of the functions and properties of the materials used;
- the ability to select and prioritize layers based on operational features.
Guided by these rules, you can easily provide warmth and comfort in your home for many years.
