Facade thermal panels for exterior decoration of the house are a modern material with a number of interesting properties. With its help, in a very short time, you can update the look of your home and make it significantly warmer. The appearance of these panels is very interesting - they imitate brick or masonry, and very authentically. Today we will find out the structure of this amazing material, analyze its pros and cons, and also see how it is mounted.
Let's start from the most interesting - the characteristics of the hero of our review.
What is its zest, and is there any point in contacting him? Here's what we know:
1. It consists of several layers, each of which performs its own functions. We will analyze the detailed structure a little later, now we will say that there are usually three or two layers: base, thermal insulation and decorative part.
2. The panels have a very low level of thermal conductivity.
3. Depending on the type of insulation used in the composition, such panels can improve the sound insulation performance of the room quite well.
4. The material is strong and dense enough to be used even in harsh atmospheric conditions. It withstands static and small shock loads well.
5. Manufacturers of such panels promise a maximum service life of the thermal panels of 50 years. At first glance, this is a lot, but let's not rush to conclusions, since this does not apply to all products, and a number of questions arise that simply need to be answered, which we will do in the next chapter.
6. The material is inert against the biological effects of bacteria, fungi and insects.
7. Temperature differences are not terrible for him - the operating temperature range is huge (-170 / + 170 degrees Celsius), it can be called extreme.
It would seem that before us is almost an ideal material for finishing and insulating a house, but buyers it is acquired reluctantly, and there is a simple explanation for this.
So, we got acquainted with the characteristics of the material, these are definitely its advantages, but in most cases these are just numbers that say little to an ordinary user. Let's now consider the real advantages and disadvantages noted by home owners who have chosen thermal panels for their decoration.
Let's start with the positive moments:
1. First of all, people note the ease of installation. The products are lightweight and have a large area, so the work goes quickly. The material is easy to lift and cut.The panels have locking joints, due to which they are easily joined and held securely.
2. Panels are really good at insulating facades. Their use allows you to protect the walls from freezing, and move the dew point outside. How effective such insulation is can be said by comparing the type of insulation material used.
Products are resistant to moisture, they are waterproof, however, water can still penetrate under the finish if poorly installed.
4. The low weight of the thermal panels is also important because the load-bearing walls of the building will not experience strong additional loads.
5. The decorative side of the material also does not react to water, practically does not absorb it, and does not deteriorate under the influence of ultraviolet radiation, which allows the panels to retain their original appearance for many years.
6. Caring for the panels is exactly the same as for ordinary clinker bricks, that is, you can immediately forget about the need for periodic processing and cleaning - a worthy plus.
7. The panels are presented in a good assortment. To your taste, you can choose options that imitate brick, stone, log or block masonry.
So why are thermal panels taken so rarely, are their shortcomings so significant? In fact, yes! There are few of them, but two of them are quite serious:
Here we mean rodents, who will gladly equip themselves with a warm home in foam. No matter how hard you try, they will find a loophole, and then the thermal protection of the house can be seriously affected. In general, the point is controversial. It should be borne in mind that the promised dates are forecasts of technologists, and as it seems to us, even of marketers. The panels appeared on the market about 10 years ago, so nothing has been tested in practice yet.
Facade thermal panels
What are thermal panels usually made of? There are two varieties - two-layer and three-layer.Let's break them down in order.
Two-layer panels are an affordable type of such material.
It is based on extruded polystyrene foam, on top of which decorative elements are glued. The rigidity of the entire structure is given precisely by its insulating part.
This material has the following properties. Service life 10-15 years (again, provided there is no external influence). The material is not resistant to aggressive environments, which can cause it to deform.
Flammable - When ignited, the flame spreads very quickly and produces a lot of pungent smoke.
Such panels should be used only for installation on a flat base, since their rigidity is not enough for installation on a frame.
We actually described three-layer thermal panels when we broadcast about the advantages of this material. At the base, they have an OSB panel, which significantly increases the strength of the material as a whole. In the middle there is a layer of polyurethane foam - this material is also quite strong and dense, locks are formed on it around the entire perimeter of the panel, which were not in the previous version - this structure allows you to avoid the appearance of cold bridges.
The insulating properties of such panels are higher than those of their counterparts.
For both panels there is a finishing layer. Usually it is clinker, which, by the way, can be glazed, or polymer elements made mainly of acrylic. Both options have a long service life, easily tolerate weathering and look beautiful, however, clinker still looks more natural and richer, and therefore costs much more.
Artificial stone, ceramics, porcelain stoneware, plastic, metal, and sometimes wood are also used as the material for the front side of the panel.
The latter panels are very rare and not easy to find commercially. Models look interesting under decorative plaster, the role of which is played by glued marble chips.
Interesting to know! To seal the joints between the panels for plastering, a special paste is used, the same color as the panels themselves. If you do not look closely at a close distance, then you get a completely monolithic surface.
Like any other material, thermal panels may have significant differences in quality.
It depends, first of all, on the components used by the manufacturer and the manufacturability of the manufacturing process. Let's try to give some advice to those who decide to acquire such "clothes" for their home:
Tip # 1. Material manufacturer is very important. Today, the market offers products from many companies, including Russian ones.Which of them should you give your preference to?
Traditionally, the market leaders in this segment are European firms.
They have a complete production process that includes all stages - from raw materials to finished products. The quality is closely monitored in Europe, since the standards of the European Union are modern and more demanding than ours.
Almost all manufacturers from Russia, in fact, do not deal with this very production. The fact is that these companies buy all the elements abroad, and at their facilities they only glue them. Actually, they are responsible for it.
In the event of a defect, it will be almost impossible to present a claim to such a manufacturer.
However, in fairness, it should be said that there are well-established firms that work in accordance with all international standards, and there are no complaints about the quality of their products. These include: Thermosite, Plitprom, Regent, Forland, Forska, Ermak.
The products of the Unique Multi Block company stand apart. This manufacturer does not build.
All production stages take place in Russia. The produced thermal panels are of very high quality.
Council number 2. If you decide to buy expanded polystyrene panels, then carefully examine the material - it should not crumble. The seams between the front elements should be even, and the insulation granules should not crawl out much, as this will significantly complicate the joining.
Tip # 3. Try not to buy panels with plastic as cladding, as it does not initially look attractive, and over time it can fade in the sun. The optimal solution in terms of price, appearance, quality will be panels with ceramics and artificial stone.
We have already mentioned that there are two types of mounting - frame and frameless. It makes no sense to divide their description into two parts, since, in fact, they differ little.
Therefore, let's first analyze the principle of attaching the panels, and then, separately, let's see how you need to expose the frame, if required.
Table 1. Installation of thermal panels.
Step 1 - order of joining
| So, it is not surprising to understand how individual panels are connected to each other. The protruding rectangular elements are inserted into the mating grooves.
In this case, each panel is individually attached to the wall of the house. The assembly of elements is carried out from left to right. Panels can be stacked either in a checkerboard pattern or in order.
Step 2 - cutting beacons from a polyurethane bar
| If the wall is uneven , then beacons are installed under the panels at the joints. They should be made of polyurethane foam with a density of at least 120 kg / m³.
The use of wood or metal plasterboard profiles is not recommended, however, such a recommendation does not make sense if the panel is three-layer, with a rigid base.
Step 3 - cutting panels
| In the places where the panels adjoin the window and doorways, corners of the building, they must be cut. Use for this angle grinder with a diamond disc. A good electric tile cutter with an overhead motor is also useful for a high-quality corner joint. Trimming the insulation is done with an ordinary hand saw.
You can also cut the edge of the tile at 45 degrees with a grinder, but this is difficult, and there is always a risk of chipping.
Step 4 - connection device
|Continuing the formation of the outer corner, in of the polyurethane foam part of the panel, it is necessary to make a vertical groove using a clerical knife to get space for the polyurethane foam in the joint area.|
Step 5 - first row of cladding
| A basement is installed under the first row profile. On top of it, a layer of polyurethane foam is applied under each panel, as shown in the photo. Then the first previously prepared panel is placed on the left corner of the building.
The element is placed with the required release in order to get a high-quality connection in the future.
Step 6 - panel fastening
| Holes are marked on the front side of the panel through which it is attached to the wall of the building. It is imperative to install fasteners in each hole without gaps. Fastening is carried out using dowel screws type DK.
Interesting to know! Fastening with self-tapping screws without bushings and nails is strictly prohibited.
1. Using a puncher, the panel and the wall are drilled to a depth exceeding the length of the dowel by 2-3 cm.
Then, using a doboiner, the dowel head is recessed into the panel until it is seated in a special dish-shaped socket located inside the panel.
Step 7 - filling holes
|Remaining from dowels it is recommended to fill the holes with polyurethane foam to avoid the formation of cold bridges through the metal self-tapping screw.|
Step 8 - filling the cavities
| Then the cavities formed on the horizontal and vertical joint of panels.
If you skip this stage, the insulation effect will be significantly reduced. It is also necessary to foam the interpanel joints.
Step 9 - grouting
| After finishing the installation, the panels must be repaired all seams. For this, various grouting compounds are used, which increase the system's resistance to adverse weather conditions. The color of the grout is selected in accordance with the color of the clinker.
The composition is applied with a gun strictly between the tiles, after which it is embroidered with special devices.
Attention! Grouting is prohibited when the air temperature is less than +5 degrees.
We would like to note that a clear joining of panels in the corners may not be required if additional decorative elements are used.
Installation on the frame implies the placement of vertical posts in the locations of the mounting holes. The installation of the battens is carried out using the classical method.
The expanded polystyrene panels can be fixed on the dowel screws, but with condition of mandatory foaming, since the panel can be very easily torn off.
