Thermal insulation of the walls with foam plastic

The most popular material for thermal insulation today is foam. It is easy to work with him, he warms up the room well and does not allow heat to evaporate through the walls. Most often it is used for insulating apartments in high-rise buildings of high-rise buildings, and for cladding the facade of private houses.

Advantages and disadvantages

Like all building materials, foam has a number of advantages and disadvantages.

Positive properties:

• Cheaper than other materials for thermal insulation.
• It has excellent thermal conductivity.
• It is not subject to the influence of moisture and weather conditions.
• May serve for many years.
• Microorganisms can not damage it.
• Easy to install and handle.

Negative qualities:

• Highly flammable.
• Combustion produces toxic smoke.
• Can spoil rodents.

It can be concluded that there are many more advantages. Therefore, so many people prefer this material to insulate their homes.

Installation Features

Making the walls with your own hands is not difficult if you adhere to the correct sequence when installing and adhering to technology. It is also important to correctly calculate the amount of material expended and to acquire a good tool.

Beginning of work

Before you begin work, you need to clearly find out how much material is required. To do this, simply measure the walls, which will be insulated. Based on these figures, it will be possible to calculate the number of sheets of foam. To insulate the walls of a residential building, foam plastic is usually used 3-4 centimeters thick. To insulate the roof using eight centimeter foam.

The process takes place in several stages:

• Preparing the surface of the walls.
• Installation Profile.
• Installation of the foam itself.
• Seam sealing
• Coating insulation plaster.
• Drawing a finishing layer.

Tools and solutions that will be needed in the work:

• Selected insulation: foam, polystyrene foam.
• Primer.
• Glue for plates of polyfoam.
• Polyurethane foam.
• Profile for the cap.
• Putty and trowel.
• Grid.
• Тарельчатые дюбели.
• Hammers.
• Perforator.

Wall preparation

Before starting work on wall insulation, they must be carefully leveled and cleaned. Then you need to apply a primer coat with a special mixture intended for outdoor use. After the walls are completely dry, work can continue.

In order for the first row of foam to be smooth, set the socle bar. It will also prevent the penetration of rodents and other pests into the layers of insulation.

The profile should be chosen high-quality and strong, since the durability of the material used for insulation depends on it. To keep the structure horizontally level, the profile position is checked using a level. Vertically stretched plumb lines - cords that are installed at regular intervals.

Polyfoam is installed on a special glue and fixed with dish-shaped dowels. Glue is applied on the walls or on the foam plates with a notched trowel. This is necessary in order to evenly distribute the mixture over the entire surface. After a day, after the glue has completely dried, it is possible to fix the dowels, which should be positioned as follows - one in the center, the rest at the corners of the plate.

Work with seams

To seal the seams, you can use the mounting foam, but if the gap is too large, it would be better to glue the insert from a piece of foam.

the gaps between the sheets - they should not be too large.

Exterior finish

When the foam is fixed with glue and dowels, the seams are sealed and the gaps are removed, you need to plaster the insulation. The surface of the foam is smooth, and in order to keep the plaster on it, it is necessary to glue to it a reinforcing mesh on which it will be possible to apply the finish. When the first layer of plaster dries, it needs to be cleaned with sandpaper or float. After that, you can apply the last layer of plaster, not exceeding 3 mm. Only after that the surface will be ready for painting. Warming of the walls with foam plastic does not take much time.
