The most common types of insulation of the facades of houses. BauGut facade insulation system
The modern world-wide trend – energy saving, is to a large extent related to increasing energy efficiency of buildings and insulation of houses. The latter is especially relevant for our country, where 90% of the housing stock is worn out to the limit, and in previous times, when the energy was worth a penny, no one thought about the energy efficiency of the buildings: heated buildings “with excess”, because “whistled” from all the gaps.
The most common types of insulation of the facades of houses. BauGut facade insulation system.With every heating season, the situation is getting harder: many homes do not meet any norms for energy saving, and tariffs are constantly increasing. According to various estimates, the overall picture of the heat loss of such buildings looks like this:
Hence, only one conclusion is asked: we need to warm our house. However, one must understand that there is a competent concept – “thermo-modernization of a building”. Namely, as a result of the thermo-modernization of the building, it is possible to achieve the desired effect: virtually, the complete elimination of leaks of heat. If the thermo-modernization is carried out correctly and correctly, the result does not make itself long to wait – there should be a sharp, sometimes, 60-70% reduction of heating costs.
The modern construction market, many companies offer a very wide range of all kinds of materials, heat insulators, heaters and their own insulation systems. How, in this abundance, not to be mistaken and choose the optimal warming technology?
Let’s take a look at the problem: at present, the three most well-known, home improvement technologies are used in construction. And let’s go “from the lowest to the higher”: from the less commonly used systems to the most famous method of warming up.
Relatively recently, this method of insulation has been widely used in individual construction. “Hollow masonry” is when the old rustic houses were laid by good bricks.
The general scheme of the well laying is as follows: a classic bearing wall (concrete panel, brick, etc.), a layer of warming, the outer wall – a lining with protective and decorative function. The bearing and outer walls are connected with each other by a valve with a predetermined pitch.
This method of insulation is very demanding for the waterproofing of the inner and outer walls: the layer of insulation must necessarily remain dry. Otherwise, the hit of water, the accumulation of water vapor, the transition through the “zero” in the winter season (freezing and thawing), will gradually lead to the destruction of the entire structure.
Such a method of insulation for multi-storey houses is not economically profitable: in fact, it is necessary to erect a second wall. For private homes, such insulation is suitable if it is necessary to heat some kind of extension in a one-story house, for example, a verandah. To warm the whole house, to build a second wall across the square, especially in a two- or three-storey house, is extremely expensive.
Warming up “ventilated facade”
To say it is very simplistic, a ventilated facade is a construction consisting of a metal or aluminum frame, a layer of insulating material and a facing material. Schematically, it looks like this:
The use of ventilated facades, their design and requirements to them, are determined by DSTU B В.2.6-35: 2008 «Construction of exterior walls with facade insulation and prefabrication of industrial elements with ventilated air layer. General technical conditions “, as well as, DBN В.2.6-31: 2006” Thermal insulation of buildings “.
The exterior facade of ventilated facades, according to this DSTU allowed by a variety of decorative materials – bricks, natural stone, aluminum composite panels, ceramic granite, etc., which give the appearance of the building a very solid and elegant appearance.
However, if we consider the massively available methods of insulation for the most commonly used residential buildings in our country, one can only imagine the cost of such a design for the average Ukrainian citizens living in standard high-rise buildings, not to mention its weight.
Therefore, practice shows that ventilated facades, with high thermal protection parameters, is a pleasure expensive. The mounting technology is also more complicated and requires highly qualified builders. Therefore, ventilated facades, as a method of insulation, are justified, more likely, in new buildings or office centers. In private homes, ventilation, of course, you can install it, it’s easier and it all depends on the financial capabilities of the customer.
And for the massive warming of our old houses, the following kind of insulation, which is known as the “wet facade”, is cheaper and more simple.
Warming “wet facade”
This method is the most understandable and visible to most people. Again, speaking very simplely, the heater is glued onto the wall and plastered to protect it from atmospheric influences. However, this is not quite so: a well-executed “wet facade” is a whole “pie” of various materials.
