Warming ecowool home: technology, especially the use of experience

As members of portal saves not only installation but also on the most ecowool

Modern private building more and more inclined to the principles of efficiency, today almost no house is not built without the use of thermal insulation materials. Considering the huge selection of heaters provided by manufacturers, to find a suitable in all respects an insulator is easy. Often, however, put the issue price at the top corner, and then circle the search narrows sharply. As an option - our craftsmen save on installation, self-performing the operations available, and some prefer to save and thermal insulating materials themselves. Of course, to create a home installation for the production of mineral wool, PSB and Epps is impossible, but to learn a handicraft manufacturing Cellulose Fiber - is quite real. While these are isolated cases, but, as in all things, dashing the trouble started, craftsmen FORUMHOUSE start, others will join.

In this article, we consider:

• What kind of insulation ecowool
• The scope and application methods ekovaty
• How to make their own ecowool

Ecowool - basic data

Ecowool called cellulose insulation, which is a loose, inhomogeneous mass obtained by recycling waste paper and paper industry waste.

The proportion of the cellulose fibers in the material is about 80%, the remainder being antiseptics and fire retardants, typically boric acid derivatives.

Additives are introduced into the mass in the middle of the production cycle, after the initial shredding, and from them it is sent to the final processing of the fiber. This ensures an even distribution of chemicals in bulk. It has been suggested that these substances can be dangerous to health, but because of their non-volatility and content of the material under the MPC (The maximum permissible amount) determined by sanitary standards, subject to mount technology they do not stand out to the exterior Wednesday.

If our country ecowool relatively new insulation, in European countries, it is used from the thirties of the last century with a light hand of the German developers. Like most other thermal insulators, cellulose not only minimally conducts heat but also dampens sound well - a layer thickness of 15 mm is able to absorb up to 9 dB. The coefficient of thermal conductivity ecowool comparable to the mineral wool, it limits the rate at 0,037-0,042 W / (m * C), depending on the mass density. For storage and transportation facilities in the process of packing material is compressed, its density varies in the range of 150-200 kg / m³.

When using the mass must fluff, it is some times increases in volume, and the density is selected, based on the scope and application method.

Ecowool poorly lit even under the direct influence of the flame, rather smoldering and charred, the results of tests it assigned to the second group of combustibility - T2 (moderately combustible) and a second flammability class - B2 (moderately flammable). Since, in addition to cellulose and borates, there are no chemical additives, and then the smoke-forming ability in her second grade - D2 (moderate smoke generation without isolation of corrosive substances).

But these properties are inherent in cellulose insulation as a whole, and whether a particular brand of reference samples correspond to those used for testing, depending on the manufacturer.

In any case, the barrier material ecowool not considered, and if you do not use it in potentially hazardous areas, even with a reduced content of flame retardants it remains an effective thermal insulator.

The advantages ekovaty include environmental friendliness, as used in the production of antiseptics and flame retardants conventionally considered safe. However, manufacturers of mineral wool say about sustainability of their products, and relying on the observance of sanitary norms. The absence of joints and, consequently, cold bridges positioned as another advantage, offset by shrinkage of the mass during the operation. If this feature is the material (stock at 20%) was not taken into account when laying, bridges appear, just in a different place. However, this insulation is available with good physical and performance properties, many of which are preferably selected because of reasonable price.

The scope and application methods ekovaty

Ecowool used for thermal insulation and sound insulation of both industrial and public facilities and private homes - in ceilings, partitions, Walling and roofing systems. This is one of the most popular materials in the construction of frame houses in Scandinavia. We do it not so common, but many choose samozastroyschiki ecowool as insulation.

There are two basic ways to mount:

• dry;
• wet.

In the first embodiment, it is filled with fluff pulp in a special cavity or blown unit / homemade device.

The second - the mass is wetted with water or a solution of an adhesive and applied to the structure by means of special installation.

Charging method most often used for insulation of floors, ecowool distributed evenly between the joists, compacting to 35-45 kg / m³. And use it for filling walls in frame house construction, or kolodtsevoy masonry, but less frequently, as even tamper difficult to achieve the desired density of 60-65 kg / m³.

The walls and sloping ecowool often blown by a plane profile equipment or handicraft plants based on garden vacuum cleaners. Coupled stratified seal layer obtained sufficient density without the risk of shrinkage and the formation of cold bridges. Wet process in demand for large quantities when filling or blowing-in will require too much time and effort. With regard to the effectiveness of a particular method, it largely depends on the skill of performers and compliance technology.

Personal experience craftsmen portal for the production and use of ecowool

As already noted, ecowool prefer other heaters as more accessible financially material, especially if the fill / blow out on their own. One of our craftsmen decided to go one step further and not only save on installation, but also in the raw materials.

The house was built without haste, finance will no longer speak, here and decided to zamudrit machine for the production of Cellulose Fiber. I shall describe in detail how I went to this and what had come before. Working himself watches, time is thought, that began to split hairs.

A description of all ordeals on the way to the goal as much as possible detailed and voluminous, it makes sense to choose the highlights.

Since ecowool - it's chopped up waste paper fibers with additives of other cardboard and tare categories craftsman decided to put the chopper. After studying the relevant network and forum and prikidok in AutoCAD, the idea took shape in the following structure:

• engine - 3000 rpm, 3 kW;
• capacity - about 200 liters;
• knife - a dull, not to cut and grind;
• shaft - to increase the number of turns on the knife;
• Belting.

I decided to use a shaft separate from the motor, because it is necessary to develop the maximum speed of rotation of the blade in a barrel. Bought two Japanese sealed bearing, has brought Turner to modify drawings, in parallel with the shaft ordered pulley to it 3.5 times smaller than the main shaft to 3.5 times increase in the rotational speed of the knife itself installation.

The engine is acquired at one of the dismantling, 4 kW, with the desired number of revolutions, complications arose because of lack of craftsmen three-phase network, the launch had to compensate through capacitors. Capacity was still iron barrel epoch the Soviet Union, in view of the selected wall thickness, knife cut from 4 mm thick metal. After the assembly was followed by a series of test runs, the feedstock is not thrown out of the barrel, it was necessary to weld "skirt" at a distance of about 5 cm from the knife, and then come up and cover.

The result is a machine that separates the fiber raw materials, but to this mass became ecowool, necessary to introduce reagents. Otherwise, it will be free to develop microorganisms and pests inhabit. However, this problem is completely solved, all additives are in the free market, calculate the proportion - not the biggest problem, but at the very idea of ​​a lot of potential.

Topic, fill the rack at home, under her blow out the wool, and the top Ventfasad - doable by hand. If more and wool make yourself - just beauty. Especially, some savings on the membranes and fungi. Boric acid and borax are not very expensive, and add / mix can be enjoyed in the grinding process. Perhaps it makes sense to use as a high speed drive of the tool? Powerful type grinder or with altered planer shaft.

A more common way to save money on insulation - self-fill / blow ecowool as both special equipment and services professionals greatly increase the cost of the process. As for the filling, the main difficulty here - a lot of fluff from the factory packaging, to obtain the desired volume and density. The easiest way - head "mixer" drill / Bulgarian / punch and box. The main drawback - the complexity and poor performance. Our craftsmen mechanized process.

Used mixer nozzle for the paint, length 60 cm, diameter 100 mm, a drill spinning at maximum speed. Nozzles break periodically, tearing the blade has to be restored. Speed ​​quite satisfied, three hours sleep 2,5 wool cube so quickly even basalt slab does not fit into such an area.

In the process, severely strained vibration and noise, so the craftsman decided to improve the home-made, but the best - the enemy of good. After installation of the bearing and fixing of the drill holder disappeared vibration and noise, taking along with them and performance. Massa stopped herself fall onto the shaft, and constantly ramming manually too long. Remodel was a pity, in the case went to the original version - box and mixer. The remaining amount of sleep craftsman, but also the forces and the time it took a lot more.

One of the topics the participants, turbomev, gathered similar (to completion) unit is almost an hour.

Simple tee 110 minutes PVC pipe, a drill is attached to the board, in order not flown, long suspension plasterboard (perforated belt which winds). Only the bell to do to download large portions. And so for a moment half a sack processed. The speed depends on how you will load quickly.

The cost price of the machine is minimal if you need more performance, really think of the hopper.

According to not only Fortunarai, but also other members of the branches, it is an excellent alternative not only manual pusheniyu, but also garden vacuums, in the case of small-scale, horizontal planes and the minimum investments. In addition, in contrast to the blowing dust of a "grinder" is practically no, and working with floors is one of the major inconveniences, even when using protective equipment.

But the vertical and inclined surfaces (walls, roof), most members of the forum blowing Garden vacuum cleaners with a little fine-tuning.

Even if you buy the unit for this purpose, plus the corrugation, get much cheaper than hiring a team or rent professional equipment.

Yes, and the volume of vacuum cleaners kept decent.

I bought two garden vacuum cleaner, pumped 9 tons ecowool, both alive:

• 60 m³ in the exterior walls - 3.5-4 tons;
• 60 m³ loft (floor 35 m³) - 3-3.5 ton;
• 20 m³ overlapping floors 1-2 - 0.7 tons;
• 125 m ² (25 m³) interior partitions - 1.5 tons.

Total: 200 cubes of 9 tons left 8 bags, or 120 kg.

Aldobr I have done without intermediate processes, but mostly before blowing wool pushat, here for this handy device Fortunarai, modify it if the neck and the receiver output.

If it is possible to get raw materials for Cellulose Fiber for free or at a knockdown price, and then we can chopper puzzled, but and independent for blowing and mechanical filling actually save both strength and finances - proved by our craftsmen.
