Insulation for plaster facade

Insulating the plaster facade of your home is essential for increasing its longevity and energy efficiency. In addition to improving thermal comfort, this kind of insulation lowers energy costs by minimizing heat gain in the summer and heat loss in the winter.

Plaster facade insulation usually entails adding a layer of thermal material under the outer layer of plaster to your home’s exterior. By acting as a barrier, this layer keeps heat from escaping through walls and contributes to the maintenance of a constant interior temperature. It also makes for a more comfortable living environment all year long.

Insulating a plaster facade can increase a home’s overall durability in addition to its thermal performance. It assists in shielding the external walls from weather conditions like wind, rain, and temperature changes, which would otherwise cause the plaster to deteriorate over time. In the long run, this additional protection can lower maintenance costs and increase the lifespan of your facade.

It’s important to select the appropriate insulation material for your plaster facade. Polystyrene, mineral wool, and polyurethane foam are common choices; each has distinct thermal characteristics and installation techniques. When choosing the best insulation option for your house, you should take a number of factors into account, including the climate, building codes, and your budget.

EPS (Expanded Polystyrene)	Lightweight, easy to install, good thermal insulation properties.
Mineral Wool	Fire-resistant, provides sound insulation, moisture-resistant.

Advantages of insulation of facades with foam and mineral wool

We brought a table, talked about the benefits of using both materials as the facade’s warming layer, and provided some comparisons.

Crucial! One conclusion that can be made is that mineral wool is more interesting when it comes to ensuring that the walls of buildings constructed of natural wood are insulated. It is superior to foam because of its capacity to sustain air exchange and moisture evaporation. Simultaneously, foam allows for efficient insulation installation that takes the least amount of time to complete.

Technical features of mineral wool are listed in the table.

Overall, it can be said that both materials have strong indicators, are contemporary heaters, and are well-liked and in-demand in the building industry.

Polymeric materials proved to be the heater that could operate successfully under challenging weather conditions for the longest period of time. Extensive research and testing have yielded excellent results, demonstrating that polystyrene maintains its original technical characteristics even when subjected to conditions that mimic eighty temperature change cycles.

What are the specific functional features of the foam associated with? Almost all builders are aware, after all, that foam insulation is not truly resistant to outside forces. They can quickly dry out, lose their original structure, and even collapse completely. They also have a low tolerance for the effects of ultraviolet radiation. However, the building’s facade is only directly exposed to UV radiation.

Foam insulation used on the facades

It turns out that the key to the foam’s usefulness and efficacy as insulation is how well it works when combined with a plaster layer. The plastering material needs to be applied strictly according to the technological guidelines. He will then develop outstanding performance traits.

1. A layer of plaster will protect the foam from the negative effects of humidity. The insulation itself dries for a long time, and with prolonged finding in a humid environment it becomes too fragile, completely losing its operational properties. The plaster completely eliminates this negative factor, turning the foam into a durable insulation, resistant to atmospheric effects.
2. Foam is a rather fragile material. A layer of plaster prevents the formation of dents, scratches, cracks and other damage on the insulation layer. Together with plaster, the foam is already quite reliably protected from mechanical influences.
3. When plastering foam, the fire safety level of the object increases. The foamed insulation itself is in itself, and the plaster prevents the spread of fire. However, the builders note that the professionalism of the plaster will be important here: the layer should be even, continuous, have sufficient thickness.
4. The effects of sunlight is destructive for foam, since ultraviolets destroys it, makes it fragile. But the option PENPLAST + plaster completely solves this problem.

It is clear that builders are primarily motivated by pragmatic considerations rather than aesthetic ones when plastering the insulation foam layer. Plaster’s operational qualities are greatly enhanced when it is combined with foam.

Step -by -step instructions: warm the facade for plaster with foam

It’s time to think about detailed instructions that will help you use foam to insulate the building’s facade in a high-quality manner before plastering it. The selection and gathering of all required supplies and equipment is part of the task. Prior to priming and plaster layer alignment, you must first align the base for additional insulation, create a solution, and secure the reinforcing mesh. You should also use premium wipes. The wall can already be finished and decorated with a decorative coating.

This is a breakdown of the steps involved in insulating the facade’s walls before plastering them. We will discuss materials, take into account the subtleties of the process, and offer insightful guidance from experienced builders.

Step 1. Preparing materials, tools

It’s critical to have everything ready in advance. The required supplies are as follows:

• decorative plaster for the aesthetic decoration of the facade;
• primer;
• plaster mixture.

Get everything ready.

A set of tools is also required:

• a container for preparing a solution;
• grater for plaster;
• putty knife;
• reinforcing mesh;
• Master OK;
• Fold paper for rubbing;
• drill with a mixer;
• level.

Modern building supplies include unique plaster compositions that were created especially to be used with foamed heaters. The final product, longevity, and thermal insulation properties of the insulation layer are primarily dependent on the quality of the plaster. Acrylic and mineral mixtures are used in plastering.

Be aware that while mineral plaster is more affordable and readily available, expert artists consistently recommend acrylic compositions due to their significantly superior qualities, which more than make up for the higher cost.

Sand and cement are combined to make mineral type plasters. The material performs its duties effectively during the first phase, but its overall useful life is only brief—roughly two to three years. After this point, we can already anticipate the emergence of cracks and a breach in the plaster layer’s integrity.

This plaster is the most resilient of all the varieties of this material because of the cement that is a part of its composition.

Although acrylic plasters are more costly than minerals, their lengthy service life makes their cost entirely worthwhile. There is one distinct drawback: acrylic progressively loses tone saturation when exposed to ultraviolet light. However, the mixture has a lot of benefits:

• The decorativeness of the coating, that is, additional aesthetic processing is no longer needed;
• excellent protective, adhesive characteristics;
• Very opportunity for the implementation of interesting design solutions: textured decoration "Rain", "Bark beetle" or "lamb";
• A good range of shades.

Acrylic is preferred by masters.

Step 2. Align the surface and fasten the foam

It is now time to begin wall alignment. This is a very responsible first step in direct work. The levelness of the walls will determine the overall quality of the insulation layer and installation work. Slabs are used to mount the foam, and the joints between them must be precisely level. If not, there will be no guarantee of thermal insulation. A wide spatula or rule is used to quickly check if the foam panels are evenly spaced from one another.

Crucial! "Excellent" should be the alignment of the black surface. Hide flaws during the plastering process is very hard, if not impossible. Furthermore, the irregular surface of the foam plates will cause the insulation layer’s thermal insulation qualities to be lost.

Recall the guidance! Although polystyrene foam has a low adhesion, it is a reasonably smooth material. As a result, applying glue to the surface is difficult. Increasing adhesion quickly and creating a large number of tiny pores on the surface is the best course of action. All you have to do is use a needle roller to slowly pierce through the insulation. Even the tiniest pores can be perfectly penetrated by glue.

Step 3. Prepare the solution

Using ready-made building mixtures made especially for plastering foam is advised. Master products from ecomix and Ceresit are highly valued. On the construction site, using a single mixture is typically the norm.

Finding the best combination of two in one is a smart solution: polystyrene plates can be attached to the facade and a protective surface can be created using universal glue-tucker. Additionally, distinct compounds are available on the market: one mixture is ready for plastering, while the other is meant for fastening.

Accurately determining the volume of required building mixtures is crucial. For every square meter of the reinforcing mesh surface, 6 kg will be used for alignment and 4 kg for plastering.

Knead the mixture strictly according to the instructions’ suggestions. The only piece of advice is that seasoned artisans think the solution can be made slightly more liquid, which will increase its ability to penetrate and ensure that the insulation is thoroughly saturated.

Step 4. We mount a plaster mesh

Selecting the appropriate grid is the first step. Given that we are discussing facade insulation, or work that is done externally, it is best to select the most dense grid possible. The plaster layer adheres to the net more effectively the denser it is. The disadvantage is that decorating the corners will be a little more challenging. Just give them a little more time, and the masters will handle this with ease. Seek for an alkali-resistant grid. Mesh density for foam insulation is between 130 and 160 g/m2.

Foam-reinforced mesh for insulation

Recall! Foam cannot have a plaster layer applied to it! The plaster will soon start to crumble and crack. The durability of the foam and plaster insulation-protective layer is only provided by strengthening the net.

The building’s corners, door, and window slopes must all be strengthened first. This algorithm is used to do this.

1. For reinforcing corners, take a mesh with a width of 0.3 m, 1 m long.
2. The mesh is neatly bend in the middle.
3. The solution is applied to the facade using a wide spatula. The length is equal to the grid strip, but the width should be more than 10 cm. The stripes will be overlapped, so a reserve is left for 5 cm on both sides.
4. The net is neatly applied to the corners, carefully smoothed with a spatula. You need to lead a spatula from the center to the edges, from top to bottom. The grid must be completely drowned in the solution.

Every professional builder follows its own algorithm to secure the reinforcing material on the facade’s walls.

1. First of all, the grid is cut. Remember that you can not make pieces longer than a meter.
2. Fix the grid with small fragments to achieve maximum adhesion. This is important because building mixtures quickly dry out. The normal size of one fragment is 100 by 90 cm. Another 10 cm masters are usually left to glue joints.
3. The mixture is applied with a spatula, only on one site.
4. The net is applied to the facade, well smoothed out.
5. Follow the amount of solution! If it was not enough, the mixture is not entirely immersed in it, you need to add the mixture with a spatula, redraw it again.
6. You need to work with a gradual shift to the side, and fix the grid overlap areas.

Step 5. We grind the net

One must wipe the layer of reinforcement. Use an emery canvas or specialized plastic graters for this. Circular motions are used when rubbing. It needs to be replaced if a low construction mixture struck the emery.

Incredibly significant! Grouting should only be done once the building mixtures are totally dry. The drying process for the mixture and plaster will take two to three hours when the street is overcast.

Step 6. We primer and align

The next step involves applying the leveling layer. Additionally, priming the surface is required.

1. The mixture is superimposed with a small spatula on a large.
2. Then the wall is treated with a solution. Movements should be confident, smooth, clear. When you make the most high -quality grout, you will need much less time and plaster material for alignment. There are even two millimeters of plaster.
3. Follow the lines of the joints of the leveling layers. They should not follow the junction of the grid. Thus, you will be able to make inconspicuous seams.

Grout after plaster has already been applied to the surface.

Suggestions. Mixtures used in construction shouldn’t dry out. In order to prevent the leveling layer from drying out, the plaster layer is wiped within a maximum of three days. Work proceeds quicker, simpler, and more effectively as a result.

It’s also necessary to prime. His responsible, professional masters never miss him. The primer has the ability to strengthen the finish surface’s adhesion and provide fungal protection. Experts advise applying a specific primer because it can stop fungus, mold, and surface growth. Using a roller, apply a layer of primer. It is appropriate to use a foam roller, or a model with a short pile.

Step 7. We perform a decorative finish

Recall! You must wait for the soil to completely dry before creating any decorative elements.

It is necessary to select specific plaster mixtures intended for facades. Their resistance to variations in temperature and atmosphere has grown. Both the additional components and the type of connecting component are determined by the properties of the plaster. There are plasters made of silicate, acrylic, and mineral materials.

Recall a few more crucial details! The significance of atmospheric indicators is enormous. It should be between five and twenty-five degrees, with no wind and a maximum air humidity of seventy percent.

For the longevity of your home and to maintain energy efficiency, selecting the appropriate insulation for your plaster facade is essential. Many materials have different advantages, ranging from good heat performance to low cost, so when choosing one, it’s critical to take your needs and financial situation into account.

Installing things correctly is equally crucial. If it is not installed correctly, even the best insulation will not function as intended. To guarantee that the insulation is installed correctly and avoid any future problems like moisture build-up or heat loss, make sure to adhere to the manufacturer’s instructions or hire a professional.

Plaster facade insulation can lower energy costs and increase indoor comfort. It’s a wise investment that yields returns over time, not just in the short term.
