How to build the interior walls of the foam blocks with their hands

Repairs serves several purposes - to update the housing, change its appearance and create something new.The best way to achieve the desired - to carry out alterations to the house.In this case it is possible not only aesthetically transform the home, but also create additional space.Sometimes this is a decisive factor in deciding whether redevelopment.Increasingly, consumers are creating internal partitions from foam blocks - the material allows you to quickly and efficiently build a wall between rooms with their own hands.

What is a foam block?

Penoblok consists of a mixture of concrete and synthetic or organic foaming agent.In mechanical mixing of the components, the air bubbles are evenly distributed in the solution, and after the solidification is obtained durable, but relatively lightweight building material.The partition of the blocks, the price of which depends on the strength class, in any case, cheaper construction of brick.

foam composition:

• cement;
• sand;
• water;
• foaming agent.

Advantages of foam concrete blocks:

• high sound and thermal insulation properties;
• environmental friendliness;
• fire resistance;
• large size - foam block options allow you to quickly lay out the interior walls and reduce costs in the binder;
• small volume weight;
• porous structure of the material - thanks to this property partitions from foam blocks "breathe" and no effect of fogging;
• ease of handling - material cut as a power tool, and a simple hacksaw, that allows you to create partitions of different shapes and effortlessly run utilities;
• easy installation;
• durability;
• reasonable price.

foam block Disadvantages:

• brittleness of the material - if not it could damage the transport;
• need for waterproofing the walls - aerated concrete has a high vapor permeability and water absorption;
• restrictions on load walls - you may have trouble fitting on her massive, heavy objects.

Getting Started

Foam blocks for internal partitions - choice of material

When choosing material for interior walls is necessary to pay attention to the following factors:

• foam blocks thickness - 10-15 cm;
• density of the material - for internal partitions commonly used brand of D600;
• uniformity of structure;
• bubble shape - they should be round and small (diameter 1 mm);
• absence of differences in the size of foam blocks - it happens that the difference amounts to several centimeters;
• packaging material - it must be covered with foil to protect from moisture;
• absence of cracks and damages.

Calculation of foam blocks

To calculate the amount of foam blocks measured parameters of the future wall.For example:

• its length - 4 m;
• height - 2.5 m;
• thickness - 0.1 m

This takes into account the area of ​​the window or door openings -. In this case it will be 2,0h0,7 = 1.4 m².The length of a standard foam block of the wall 0.6 m, height 0.3 m Its area -. 0.18 m².

directly the calculation itself:

• calculated the total area of ​​the wall - 2,5h4 = 10 m²;
• subtracted from the result of the doorway area - 10-1,4 = 8,6 m²;
• calculated amount of foam blocks: 8.6: 0.18 = 47.8 units.

So, for the erection of the partition area of ​​8.6 m² will need 48-49 foam blocks.

Tools and materials

For masonry walls of the foam blocks used a mixture of two kinds:

1. The classic solution - a mixture of sand and cement in a ratio of 1/4.The disadvantages of this method include masonry seam thickness and, consequently, an increase in "cold bridges".The advantages - the low cost of such a solution.

2. Special glue - the best material for the masonry wall.Its advantages:

• thin seams;
• ease of preparation;
• very good adhesive properties;
• flat, smooth surface of the wall.

To attach to the wall using embedded pins - steel plate with welded fittings.On the floor the partition is fixed by means of self-tapping pins.

to work with concrete blocks will need the following tools:

• handsaw, plane and float;
• drill with paddle mixing the solution and create holes for the socket;
• rubber mallet;
• level;
• capacity for a solution or glue;
• trowel or spatula;
• layout tools: laser level, a cord, a marker or pencil.

partition of foam blocks with their own hands - mounting

• surface adjacent to the mounting structure, cleaned of dust, and primed.
• Using lasers, otbivochnogo cord and a marker on the floor, ceiling and walls held marking the boundaries of the future partition.

• To prevent displacement of the first series of foam blocks, the floor mounted metal profile.It is used as a limiter and facilitates placement accuracy.
• The floor-screws screwed pins.Possible laying of the first layer on the solution - in this case, the fasteners are needed.

• to the retaining wall mounted or embedded pins hammered pieces of reinforcing rod.Fasteners must be in the horizontal joints of masonry every 2-3 rows.
• strictly on the level of the first series of foam blocks stacked.If necessary, reduce the size of the material using a hacksaw.Since the foam block quite fragile, align the wall should be carefully using a rubber or wooden mallet.

• Laying the second and subsequent rows of the foam block is held "vrazbezhku" - vertical joints should not be placed one above the other. Masonry is denser concrete blocks if moistened with water.

• In the process of construction of the wall is formed by the doorway.To strengthen the structure in its upper part is placed and fixed wedges fittings.It is set in the pre-cut slots in the foam blocks.

• After raising the walls, the resulting gap between the masonry and the ceiling is filled with foam.
• interior partitions from foam blocks in several layers of primer are processed and then plastered under wallpaper or other finishing materials.Facing the wall tile is held directly on the wall.In this case, the partition does not require plastering.
