Aerated concrete house with ventfasada: Installation Instructions

Along with the all familiar types of gas-concrete facades for buildings, such as plastering and brick, there is a less common options. In particular, a user with the nickname FORUMHOUSE Vzik decided to decorate the walls of his house and granite panels that mimic the texture of natural wood, securing them to the subsystem ventfasada.

facade at Vzik success.

Subject Vzik It aroused great interest among our users of the portal, so we will cover in this article:

• How to properly insulate the aerated concrete building.
• What are the features of ventilated facades.
• How to mount and fasten on Ventfasad him slab granite.
• How much is Ventfasad, and how to avoid mistakes during installation.

Nuances of warming the house of aerated concrete

Vzik aerated concrete building house in Yaroslavl. The width of the blocks - 30 cm, for example, that is not enough for modern standards of thermal resistance of enclosing structures (depending on the region of residence). Therefore, to make the house warm, comfortable, and reduce the cost of heating, the user decided to first well insulate the walls, and then mount the front.

Before we tell you about how Vzik I did it, and why the chosen as insulation rock wool, and the facade made ventilated, a little theory.

Aerated concrete - a vapor-permeable material, the gas silicate (depending on density) is both a structural and thermally insulating material.

Therefore, manufacturers recommend doing a single layer of aerated concrete wall, the width of which is chosen to Based on calculation of heating, because standards for thermal resistance in different climatic regions different.

Those. if the unit can be dispensed in a width of 40 cm in one area of ​​residence, or the other - with colder climates, it may not be enough gas concrete wall width 50 cm and more.

Second Embodiment - select aerated concrete block of smaller width and further insulate the walls. At this stage, many developers err - selected for insulation aerated extruded polystyrene (Epps). This material steamtightRespectively, the steam coming out of the house, "buries" in the insulation.

In pereuvlazhnyat end wall, and water vapor condense, freeze under certain conditions. Ice starts to "tear" block, which leads to lower performance of the wall structure.

Also add that the aerated concrete has a certain selling humidity, ie blocks placed in the wall, will have some time to dry. At warming Epps on gazosilikata aerated concrete begins to dry inside (especially in the first 1-2 years, associated with the "wet" processes are produced when additional interior finishing work). As a result, the developer may face the problem dampen internal walls, fungus, mold and spoilage finish.

If warm aerated Epps (which is not recommended), make sure you do inside the house reliable vapor control circuit. Also, there are a number of important technological nuances associated with the preparation of extruded polystyrene foam for installation of the system "wet facade". In particular: obligatory manual trimming is performed from the glossy surface Epps layer to increase the adhesion of glue mixture to the plate.

Therefore aerated be vapor permeable insulation to insulate, for example, mineral wool. If done the so-called warmed "wet facade" and the choice fell on polystyrene, such as PSB-S 25F (by the people "foam", not to be confused with the material Epps), the insulation layer thicknessis selected on the basis of heating and calculation is based on vlagonakopleniewall construction, so as to output a dew point in the thickness of insulation.

Features of ventilated facades and stages of its installation

So, Vzik decided to warm the house with mineral wool. Insulation thickness of 15 cm. Hinged ventilated facade. This is necessary in order to bring the water vapor that enters the heater to the outside - i.e. aerate structure.

The width of a ventilated air gap should be 3-4 cm.

Looking ahead, we say that do hinged ventilated facade with foam insulation is prohibitedBecause This combustible material, and in case of fire, the flame spreads quickly around the house because of the thrust in the air gap.

Vzik (User FORUMHOUSE):

The principles which I have been guided in choosing the type of facade, the following - the durability and ease of care. I did not want something from time to time to finish, tint, etc. Hence: a variant with "wet facade" was dropped immediately. Brick facade, too, did not want to, so settled on porcelain stoneware and wood.

Facades of granite is traditionally associated with residential skyscrapers and commercial buildings. However, when "direct hands" and the proper design of a country house, with this type of facade, it looks great, and does not look like an office.

The durability of the facade is largely dependent on the type of finish. Gres - an artificial stone obtained by firing at high temperatures, the compressed mixture of clay with the addition of quartz, feldspar and dyes. At the exit - sturdy, durable and wear-resistant material, not subject to the destructive effects of adverse weather conditions and microorganisms. Porcelain tiles does not fade over time when exposed to sunlight, as staining is done on all the tiles depth. Most running sizes of porcelain stoneware: 30x30, 40x40 and 60x60 cm. Thickness: 1.4 mm to 8 cm.

Mounting ventfasada began with the installation brackets subsystem, which then (after mounting) fixed stoneware tiles.

The bracket is fixed to the wall through paronitovye gasket with step 60x60 cm. As the fasteners used plastic facade anchors.

Plastic "body" and paronitovye dowels or, alternatively, a plastic gasket isolates the metal anchoring from aerated concrete. Thereby eliminating cold bridges.

After installing the brackets on them as skewers strung mineral wool.

Rockwool mounted in a 2 layer. The first layer thickness of 10 cm. Second layer - 5 cm with overlapping seams of the first layer.

In the corners of wool layers stacked with ligation so as to avoid blowing the joints.

Each insulation layer is additionally fixed by dowel-fungi.

After installation of the thermal insulation heater circuit closed water- and windproof membrane. This membrane produces water vapor coming through the wall from outside the house, but does not allow atmospheric moisture (rain and snow) to get into the insulation.

Vzik:

I took a different density mineral wool. The second layer (outer) more dense than the first. Although rockwool thinner top layer has a specially coated, hindering blowing of insulation fibers, I decided to be safe in case of heavy rains. Therefore, the whole house rolled membrane.

Individual attention, shutters, that the user has installed on windows and door. They perform the function of anti-vandal and protect the interior from the cold in winter and heat in summer.

Vnakladku shutters mounted on special brackets, which was put under the pad of extruded polystyrene, in order to avoid cold bridge.

T-shaped mounting profile of the metal strip welded to 4 mm thick. Shutters fastened on the front wall plugs.

Vzik:

Profile roller blind I chose with ventilation slots between the slats. Due to this, if not properly closed shutters, it passes through the slit light and air, but the house did not fall flies and mosquitoes.

Because granite shutters are closed, the engine has a configuration and management over the air.

Following the installation of brackets and a heater stage - installation of lath.

In brackets fastened horizontal T-profile, with a space from the insulation is not less than 3 cm. Profile fastened to the two self-tapping screws per bracket. Profile exhibited strictly according to the plumb line at the same time to equalize the difference walls.

Brackets clipped with the expectation that they closed the shutters.

Then at T-profile fastened U-profile, on which is further hinged granite.

Therefore the profile is fixed in accordance with the layout of vertical seams given project.

Cap homes insulated Epps.

After that started hanging porcelain. The first row of the most crucial, it needs to be put strictly on the level, as it determines all subsequent geometry of the assembled tiles. Vzik

Porcelain tiles mounted on colored tiles with stainless steel clamps. All vertical U-profile painted in black. It is necessary that the vertical seams are "lost" against the background of horizontal.

Socket for decorative separated slight shimmer.

As the "tree" on the facade Vzik use siding WPC (wood-plastic composite), it is made into decking. The principle of selection is similar to the choice of façade material - durability, low maintenance, weatherproof nonsusceptibility. Therefore, the options have disappeared from the natural wood. Siding WPC is also attached to the clamps of stainless steel.

Vzik:

The color I chose a light walnut, and, apparently, has not lost.

At this stage, the house has found the "face".

After sewing the whole plane of the facade proceed to the installation of ceramic granite slopes. slopes are also close guides and roller shutters boxes.

Ventfasad completely concealed mechanism of the roller blind, so when lowering the impression that they "leave" from the wall.

At the door to the slope framed by decorative laminated F-profile.

In window profiles not set because so I obtain a clean cut.

On the facade of the fitter team took 3 months. According to the user says he got what he wanted. Caring for such a facade is easy, you can simply wash pressure washer. Climb and tint or plaster facade is not necessary, and can be easily replaced, if necessary, tile, tilting the "whiskers" capping.

Before we tell you how much it cost the facade, and about some nuances should be aware of those who want to repeat the experience of the user, a few photos showing the fully finished house.

Vzik hem roof overhangs, set vodostochku, brackets mounted to the implement (lamps, motion sensors, etc.). The wires are hidden in ventzazore.

Vzik:

I even compared the costs of home heating and insulation to ventfasada installation and after. It turned out that savings of around 30%, so it washed away in the additional insulation is.

How much is Ventfasad of granite, and how to avoid mistakes during installation

on the façade of the following expenses:

• Remuneration assemblers Brigade - 215 thousand. rub.
• Porcelain tiles - 115 thousand. rub.
• Mineral wool and subsystem - 240 thousand. rub.
• WPC siding - 75 thousand. rub.

Total for the installation of 300 square meters. m facade took 645 thousand. rub.

Note: The prices are for the year 2012.

And at the end of the article we give blitz answers to common questions from users, to help avoid errors when installing ventfasada of granite.

Can I use instead of the metal sub-economy version in a wooden bars?

Trying to do, "as cheaply," will lead to the need to repair and alteration of the facade. Wood - the "live" material is subject to seasonal accumulation of moisture, dryness, changes in geometry, etc., all of these shifts will affect the finishing coat, and not for the better.

dyadyushka_Harry (User FORUMHOUSE):

Why horizontal profiles? What happens if you attach the brackets to the wall vertically and fasten them only vertical profiles?

Vzik:

Horizontal profiles we ask the mounting plane and the vertical profile of hard-releasable entire system in two planes. Brackets define stiffness in a third plane. If you remove one bolt, the rack will wobble to the right and to the left, porcelain tile will fall under wind load, as total hardness is not provided.

To compensate for thermal expansion is necessary to leave a gap between the panels.

Basis of ventilated curtain wall - subsystem. The subsystem can be made of:

• of stainless steel;
• galvanized steel;
• aluminum.

Stainless steel - the most expensive option. With it, as well as galvanized, more difficult to work. Aluminum, reviews fitters installed faster. But choice of subsystems, such as the type of fasteners and should always be based on the calculated parameters system - bearing wall facade, and acting on it loads.

Fasteners necessarily calculated on digging (A force which pulls the anchor from the wall), since the facade of the action of dynamic wind load (depending on the region of residence). When calculating not forget to take into account the weight of the final coating. For example, ceramic and may weigh 21 kg / sq. m, and 26 kg / sq. m, and this implies different load on the subsystem!

According to the rules: Ventfasad placed on the wall of aerated density of not less than D600 and using special fasteners for silicate blocks. If the top coat is heavy, it will likely have to abandon the use of aerated concrete anchors and use chemical anchor.

Also the question arises how to mount subsystem - on the screws or rivets?

Nikolay28 (User FORUMHOUSE):

Those subsystems that I know, according to the rules are fastened only at the rivets. Because of the wind load over time the screws can become loose.

In ventfasada all elements must have a long service life and corrosion resistance. Rivets diameter of 4.8 mm must be made of stainless steel. Of course, the appropriate tool is required for their installation.

The golden rule of any facade - savings in components, materials and technology, leading to costly rework. The service life of the system components should be equal to lifetime of the facade. So excluded the weak links, which "will fail" earlier than required overhaul of the entire facade and houses.

Learn more about the features ventfasada installation and nuances of its operation can be subject Vzik: finished Ventfasad: 150mm insulation, granite and wood. Also we advise to study the section "Facades and facade materials", where you can find the answer to any question on the selection, installation and repair of the facade.
