Features of the material

Since 98% of the air is made up of foam, the rooms can retain as much heat as possible. As a result, this material is utilized for insulating foundations, floors, attics, basements, and walls in residential buildings in addition to warehouses. Actually, the foam’s rising popularity is the only explanation. Not at all. This material has additional positive attributes.

Advantages

1. Sound and thermal insulation of rooms.
2. Small weight, which helps to reduce the load on the bearing walls. This means that polystyrene foam is suitable for completely old buildings.
3. Universality of application. It can be used for both internal and external work, for residential and non -residential premises.
4. Moistenous properties.
5. Affordable price. The cost of foam is quite low compared to other materials.
6. Duration of operation. This advantage can be considered relative, since unprotected foam under the influence of sunlight is quickly destroyed. But if it is immediately closed with facing material after installation, then the service life will be up to 30–35 years.
7. Safety. Foam is covered with antipyrins that do not allow the heat insulator to smolder and secrete caustic substances.
8. Prevalence. This insulation can be found in any construction store. In this point, at one point there are plates of different densities and thicknesses.

Positive points abound, as you can see, and it’s now obvious why people who wish to warm up purchase foam.

Flaws

Positives positives, but every material has a number of drawbacks. They shouldn’t be disregarded in any way, and occasionally a few drawbacks can balance out a lot of advantages. It has certain drawbacks of its own:

• fragility. A plate of any density and thickness easily breaks. This must be taken into account in the process of trimming and installation, it is advisable to be as delicate as possible with this material;
• Small vapor peripation. Do not hope for natural ventilation if the house is sheathed with polystyrene. Couples will accumulate in the rooms, and this will lead to a deterioration in microclimate. This material is categorically not suitable for insulation of cost buildings;
• poorly tolerates the effects of ultraviolet radiation and some paints and varnishes;
• If the polystyrene is not covered with antipyrins, then it is easily ignited, while caustic smoke stands out;
• Love of rodents and birds. Rodents settled in plates and make their nests. Birds pick hooks in plates that are not closed with facing material.

After educating himself about all the benefits and drawbacks, the customer decides whether or not to buy this insulation.

We’ll walk you through the process of correctly insulating and exterior foam cladding your home in this article. We will provide you with comprehensive instructions that will simplify every step of the project, from material selection and preparation to application methods and final touches. This guide will give you the information you need to improve the exterior durability and energy efficiency of your home, whether you’re building from scratch or remodeling an existing one.

The main types of plates

There are various densities and thicknesses of plates available for purchase. The following sizes are more frequently utilized in construction, and the thickness of the plates is expressed in millimeters:

It is also possible to present an 800 mm sheet thickness option to the buyer. In our nation, insulation for residential buildings is best achieved with a diameter of 100 mm. Regarding the material’s density, the following choices are available:

• 15 kg/m 3;
• 25 kg/m 3;
• 35 kg/m 3;
• 50 kg/m 3 .

They advise selecting medium-density foam in order to insulate the house effectively while also avoiding the need to worry about mechanical damage, which frequently poses a risk to the facade. Of course, using the maximum density will result in greater reliability, but this material will also cost more.

How to choose material?

The selection of foam ought to be handled as closely as feasible. Because insulation is so widely used, people frequently pretend to have it. To avoid purchasing a subpar product, follow these guidelines:

1. The color of the foam is only white and uniform. If there is a yellowish tint or spots, refuse this purchase.
2. Granules of the same size and tightly stay with each other. If interspersed too large or small sizes are visible – this is a bad foam. And if everything is also crumbling with a slight touch, then this insulation is unlikely to maintain heat in the rooms.
3. Proven manufacturers always provide all sanitary and hygienic norms and technical research. Therefore, we will definitely ask for quality certificates.
4. It is better to buy a purchase in a specialized store.

The foam will only be long-lasting and of excellent quality in this situation. Additionally, the process of insulating the house will yield positive results and allow for a reduction in the amount of money spent on heating.

Insulation technology, how to properly warm the walls outside

Those who choose to insulate the building themselves ought to thoroughly research the topic of foam sheathing for houses. Despite the material’s light weight, it must be fixed with reliability because it will determine how cozy and warm the rooms get. As a result, we will go into greater detail about technology.

Surface preparation

Foam from the exterior from the preparatory phase starts to form the walls. To ensure that the insulation is as effective as possible, take the following steps:

• All hinged structures are removed from the wall;
• The outer wall should be even so that the foam is tightly adjacent to the surface. Therefore, all cracks, hollows or excavations are closed by plaster mortar. If the differences are too large, then it is better to completely hide the wall at once;
• the surface is dried;
• remove dust, pollution, fat spots;
• To protect against fungus, mold, as well as an increase in adhesion properties, the surface is treated with a primer of deep penetration.

Marking

The starting bar is set so that the foam does not crawl during installation and continues to hold consistently for the duration of its service life. Dowels are used to secure the part. However, they have to use the building level to ensure that the horizontal starting bar is fixed.

It is advisable to make preliminary approximate markings prior to installation. This is required to ensure that the foam plate joints do not line up with the upper corners of the doors and windows. If this isn’t done, there will be cracks in this area after plastering. The windows will turn into cold bridges where icy air can easily enter if the house is covered in siding or other panels that sit on top of the foam.

Installation of insulation on the wall and facade

Slabs of heaters are adhered to with a unique glue. Avoid purchasing a generic, stylish composition for use on facades. Certain substances may damage the foam and compromise its integrity. We install foam in accordance with the following schedule:

1. Prepare the adhesive composition.
2. Apply glue around the perimeter of the plate and several blunders in four places in area.
3. The side parts of the foam can also be smeared with glue, which will help to secure the part.
4. We put the first row in the starting bar and tightly pressed to the surface of the wall.
5. Periodically check the evenness of the installation.
6. The next row is laid with a shift for half a plate.
7. If the adhesive composition appears to the surface of the foam, then we immediately remove.

Additional mount

The use of mechanical fasteners is also required for the finish to adhere consistently. Dowels-zontics with a wide hat are appropriate as such fasteners.

They are purchased with a margin, which is determined by requiring five umbrellas to be used on one burner. Two insulation thicknesses are represented by the fastener length.

When the glue started to grab a little, the foam was mechanically fastened. Use a puncher to create a hole, then insert the tip into the hole to accomplish this. Then, depending on the kind of fastener, drive or screw the core.

Charging angles and slopes

You must first begin cutting the parts to the appropriate size if you want to qualitatively complete the slopes with your hands. Moreover, the same glue that is used to adhere foam to the facade is also used to adhere the details together. After that, the design is given an hour or so to dry.

Next, glue the pre-made slopes in place. A tiny bit of glue is put inside the base and firmly pressed in place. Remove any extra glue right away with a rag.

The angles are a little trickier in this case. Installing the first foam plate allows it to extend beyond the edge to the stove’s thickness.

The component is then glued to the protruding edge on the opposite wall after being firmly pressed to it. The projecting portion ought to be situated on a different wall in the following row. Thus, switch up until the very end.

Reinforcement and plastering

The foam has to be artificially strengthened because it is not as durable as we would like. Use fiberglass mesh and the same plaster or glue solution to accomplish this. Take the following steps:

1. To improve adhesion, the surface is treated with soil or small holes are made using a roller.
2. Apply a thin layer of solution.
3. Apply a fiberglass grid.
4. Smooth the spatula.
5. If there are places where the mesh is not completely immersed in the solution, add a little fresh and smoothed out again.
6. The second row of the grid should be laid 10-15 cm to the previous. This will help to avoid cracking.
7. Processed areas should be even.
8. The surface is left to dry.

Primer and finishing

The outcome will determine what happens next and what needs to be done. The prior layer needs to completely dry if the decision is made to close the foam with ornamental plaster. Then soil is applied, and the area is once more given time to dry. Decorative plaster application will be the last stage.

However, as a decorative finish, you can go with tiles that mimic real stone or clinker that resembles brickwork. In this instance, priming the surface is also required before moving on to the part chromating process.

Step	Description
1	Prepare the surface by cleaning it thoroughly and ensuring it"s dry.
2	Measure and cut the foam panels to fit the dimensions of your house.
3	Apply adhesive to the back of the foam panels and press them firmly onto the wall.
4	Secure the panels in place using screws or nails, ensuring they are evenly spaced.
5	Seal the joints between panels with foam sealant to prevent air leaks.
6	Allow the adhesive and sealant to cure as per manufacturer"s instructions.
7	Finish by painting or applying a protective coating to the foam panels.

Foam insulation sheathed on the outside of a house can greatly increase energy efficiency and improve curb appeal. There are a few crucial steps in this process that, if followed correctly, can produce a long-lasting and insulated facade.

First things first, preparation is key. Make sure the surface is clear of any debris or loose materials, dry, and clean. This avoids problems later on and lays the groundwork for appropriate adhesion. Next, measure and cut the foam boards carefully, being cautious around windows, doors, and other openings, so that they fit snugly against the walls.

Using the appropriate adhesive or mechanical fasteners intended for outdoor use is necessary when applying the foam boards. In order to guarantee that the boards are firmly fastened and correctly positioned, this step calls for accuracy. To maintain the effectiveness of the insulation, follow the manufacturer’s instructions for sealing and spacing.

After the foam boards are positioned, it is crucial to seal the edges and joints. Fill in any spaces around windows, at corners, and between boards with sealants that work well with them. This step helps to prevent drafts and moisture infiltration in addition to improving insulation.

Lastly, think about how your sheathed facade looks. You can decide whether to cover the exposed foam boards with siding or stucco, or to leave them uncovered, depending on your preferences. This last detail adds a second layer of weather resistance in addition to improving curb appeal.

You can successfully sheathe your home with foam insulation by carefully following these steps, which will increase its durability and energy efficiency while also making it more comfortable to live in.
