If you warm the attic of a private house by all the rules, you can seriously save on heating costs. To do this with your own hands, you need to understand what the technology of this process is and what material to use.
For many years no one has been warming roofs with straw or blankets. While the attic is no longer the place where various rubbish is stored in the cold. Today, many private houses are equipped with attic space converted into a loft - attic. It is complemented by a variety of furniture and household appliances. Therefore, the attic, arranged in this way, must be well insulated and protected from moisture. In addition, if you make high-quality insulation, you can prevent heat loss throughout the house.
How to heat the attic?
In order to understand how to insulate a cold attic, you do not need additional skills. Now stores provide a wide selection of the most diverse types of insulation, but consider those that are among the buyers considered the most convenient to use and reliable. For example, polystyrene foam, mineral wool, polyurethane foam, as well as expanded clay have such qualities. If you make enough effort, you can do the warming of your attic yourself, without resorting to help from the masters in this matter. Before you heat the attic in the house, you need to choose the perfect material. Each of them has its own advantages and disadvantages, as well as the nuances of installation. We must not forget that before starting to warm the attic, it is necessary to process all the cracks and joints of the roof with a mortar.
Attic insulation materials
Many buyers are wondering what is the best way to insulate the attic at home. First of all, the material with which you plan to insulate the attic, you need to choose, given what the ceiling is made of. If it is made of wooden beams and the floor is wooden, then you can use light bulk materials, as well as materials that come in rolls and slabs. Thus, it turns out that you can choose from many varieties. But in a situation where the overlap is made of concrete in the form of a slab, then in order to insulate it, dense materials in the slabs are useful or, at worst, bulk, but necessarily heavy, because cement screed can be made on top of them. If you are thinking about the problem, what is better to insulate the attic ceiling, then the same bulk, roll and tile materials are suitable for this.
There are different types of materials that help to insulate the attic.
Types of materials for insulation
- Bulk. These include sawdust, cellulose insulation, algae, polystyrene granules, glass wool, flax processing waste, straw, etc.
- Roll. The most popular among them: mineral wool, glass wool, algae, linen insulation.
- Tiled and matte. Among these materials, you can distinguish foam, straw, algae, mineral wool in the plates.
Before choosing what is better to heat the attic of a private house, you need to familiarize yourself with the qualities of thermal insulation of the material, whether it is available in a certain region, can it suddenly change its properties during temperature changes, is it convenient to mount, and then use, and also, it is also very important how environmentally friendly or natural the material is. For example, if you build a house of wood, and use foam plastic as the attic insulation, then this would be somewhat stupid, since wood is such a material that can breathe, and foam cannot. As a result, dampness will reign in the room, it will be unpleasant to be in it, and the elements from the tree will soon rot and deteriorate. Well, of course, you need to choose a material for insulation based on personal capabilities.
Insulation of the attic with filling materials
The attic has been insulated with filling materials for many years, this method has been recommended and tested by time. Often they use it when the floors are made of wood, then it is only filled up between the logs.
The technology of how to heat the attic with such materials is as follows. Kraft paper or a layer of any other similar material is laid on wood floors or coated with clay, sprinkled with a material with the property of thermal insulation, a layer that is determined, given the region in which you live. Then the boards spread, they can already be stepped on. The hatch that leads to the attic should also be insulated.
There is a version of the fact that insulation made on the basis of eco-friendly materials is soon crumpled and compacted, but in fact this is not entirely true, this opinion is too exaggerated. Therefore, you can safely choose the one that you like the most and is suitable for the price category.
How to insulate the attic with linen?
Consider how to heat the attic with linen coating. If you have the knack and minimal knowledge in the field of physics, then you will succeed. First you need to cover up all the cracks in the wood floor. This can be done through clay, or you can use new, more innovative materials. Kraft paper should be placed on top of the clay layer or the entire floor surface should be coated with clay with a layer of at least two centimeters.
Bonfire is a waste material obtained after processing flax. The material is inexpensive in most regions, is resistant to fungi and destructive microorganisms, is quite lightweight and does not begin to rot over time. Mice do not dwell in such material, because they cannot make a hole in it, it immediately crumbles, closing the passage. The bonfire coalesces over time, but it can always be poured on top or exchanged for a new one. The indisputable advantage of flax material is that there is no difficulty in disposing of it, you can only scrub it from the attic surface and then burn it, but glass wool, for example, is not endowed with such quality.
We warm the attic with our own hands with the help of flax, pouring it with a layer of 18-35 centimeters. You don’t need to cover anything on top to make it convenient to move around the attic, you can put wooden boards, but you don’t need to cover them with the entire surface, creating a regular floor, you need to give the fire access to the air to give moisture. It is imperative to make ventilation in the attic, consisting of small windows. Periodically, you need to check the fire, if you notice that it is slightly raw, you need to open the windows to dry linen and space.
How to insulate with sawdust?
When wondering how to properly insulate the attic, many people decide to use the old, but proven method - insulation with sawdust. This method is especially suitable for those places where the woodworking industry is located nearby, because you can just buy sawdust there at a very low price or even, if you are lucky, get them for free in unlimited quantities.
First, how and in the method of warming with flax, all floor slots are smeared with clay. You can sprinkle some sand on top. Its function is to fall asleep in the gap in case the clay layer gives a crack. Then everything is sprinkled with slaked lime with carbide. This layer will protect against mouse populations. Sawdust is poured on top with a layer of 20 centimeters. Sawdust is a material that is highly flammable, so it’s best to sprinkle slag over it. Especially in the area around the chimney and other hot elements. In addition to slag, other materials can also be used, for example, flame retardant treatment. You don’t need to lay anything on top of the sawdust, except for the boards on which you can move around in the future.
How to insulate with straw?
To understand how the attic is insulated with straw, the process can be compared to warming with sawdust. Under its layer, you also need to lay craft paper or something similar to it, you can also spread the floor with an clay layer up to five centimeters thick. Then, on top you need to pour straw with a layer of 20-50 centimeters, it all depends on the region of residence and temperature in the winter. To reduce the flammability level of straw, it can be smeared on top again with a clay layer a couple of centimeters thick. To prevent the appearance of mice, you can use the same method as in the sawdust method, or any other popular proven method.
How to insulate the attic of a private house using roll materials
Roll materials are well suited to insulate the attic, because they can be placed between lags up to 18-20 centimeters high. Most often, materials that are easy to cut and that take the desired shape are used.
How to insulate mineral wool?
Mineral wool is a modern material used to create thermal insulation, it is quite widespread. Attic is often insulated with it because it does not ignite, does not rot, and is not subject to the spread of microorganisms and mice, as well as moisture.
At the bottom of the wood flooring you always need to lay a vapor barrier film, its joints are usually glued with specialized adhesive tape, because cotton wool has the ability to absorb moisture, but almost does not release it back.
Top films can already be laid minvata rolls. In the process of carrying out this process, you must prudently put on such clothes with which mineral wool does not get on the skin. Cotton wool accepts its full size over a period of about 15-20 minutes. It does not require that it be covered on top of anything, however, wood boards can be laid out to move around the room. Material with the property of waterproofing, in order to protect mineral wool from leaks, spreads only under the roof itself.
How to insulate with algae ramps?
Algae ramps are ideal for insulating attics. Due to the addition of sea salt and iodine to the composition, rodents will not appear in this material, and rot and damage by microorganisms will not occur. Gangways are mats consisting of sea grass zoster. By its thermal insulation, such material is no worse than modern, but unnatural heaters. One of the main advantages of such a warming material is the environmental component, as well as the fact that the drains are practically non-flammable, they can only smolder, but nothing toxic and dangerous to health is released from them.
Let us consider in more detail how the attic is insulated with the help of sea grass. Algae are not affected by moisture, so you do not need to insulate the floor surface, you can directly lay the stairs on the floor with a layer of a thickness of about 20 centimeters or more. You can arrange a wooden flooring surface or lay boards for moving around the attic.
Use sea grass as a heat-insulating material harmless to the health status of the inhabitants of the house, because they provide excellent climatic conditions in the room, as well as in the air useful iodine.
Using linen insulation material
Modern Variable insulation materials from flax are made in rolls, the same as mineral wool. Only their advantage over this material lies in the fact that flax insulation is absolutely environmentally friendly. Flax is a suitable solution in order to insulate the attic of a house made of wood or a room made of other natural materials.
Before laying linen rolls, you need to fix all the cracks in the floor surface with clay, another vapor barrier required. Flax insulation is laid on top, but it is neatly joined to prevent gaps.
