Construction of an extension to the house of foam blocks

Foam - one of the latest developments in the construction sector.This material has a number of indisputable advantages, and enjoys great popularity.His cellular fractional structure characterized by low thermal conductivity, which allows you not to spend money on additional insulation.Small weight and dimensions that exceed the size of a brick or sawn stone (standard size foam block - 600h300h200) can significantly save sand and cement in construction.

Content

With its unique porousstructure, concrete blocks have good sound insulation.These same properties create the effect of "breathing" walls, which prevents extension of the occurrence of condensation, provoking the formation of mold or mildew.environmentally friendly natural ingredients are used for the production of aerated concrete blocks.

Planning and drawing an extension of the foam to

home first determine with outbuildings place, its size and height.It is important that the roof construction was a little below the house roof.

how - to construct a house - of - foam blocks 6

  1. Anticipate and plan communication line.This must be done at the initial planning stage, otherwise you run into the problem of the gasket after the construction of walls.
  2. is also necessary to provide for the possibility of the expansion joint in the splices and extension of the main building.
  3. Doorway in the annexe can be arrange in the place where there is a window on the outside wall of the house, and you can hack into the supporting wall.In this case, consider the external load.

Construction of the base for the construction of

Raise extension to the house of foam blocks with their hands lighter than traditional materials.The foundation for the extension of the foam blocks is done by a filling belt of concrete or of themselves elements of the future design.

  1. base depth depends on the height and weight of the extension.For small enough structure to dig a trench around the perimeter of the depth of 50 cm and a width of up to half a meter.At the time of laying the foundation of the foam blocks is important to pay attention to insulation and waterproofing of underground parts of the structure.The foundation is affected by ground water and temperature changes.
  2. soak into the material moisture can freeze in the winter and promote the destruction of the base and its strength depends on the condition of the walls.At the start of construction on a zero cycle, begin work on insulation and waterproofing.For insulation use polystyrene foam, mineral wool, penoplex and other materials.
  3. laying insulating panels directly at the time of sealing.Dried out foundation coated with a water-repellent compound.To him attach insulation boards covered with hot, about 70 ° C, with bitumen.Attach them further there is no need.When backfilling land squeeze insulation to the ground.Elements of thermal insulation material should protrude above ground level by about 50 cm
  4. There is another type of insulation of the foundation -. Polyurethane foam.This new and more expensive tool, but its application solves the problem of maintaining the temperature of the waterproofing and at the same time.By means of a special machine made spraying polyurethane layer to 5 cm on the surface of the foundation.Covering a thickness of 12 cm corresponds to the usual Styrofoam.

These materials are successfully cope with the task of thermal insulation and waterproofing of the house and prevent the emergence of cold bridges, which, in turn, protects the dwelling from the appearance of mold and mildew on the inside walls.

Walling for the extension of the foam blocks

of frozen and to withstand the perimeter of the base, lay roofing felt or rubemast.This layer, laid on level terms "dew", prevents the penetration of moisture above the floor level.

  1. When laying the first row of the walls of the foam blocks using ordinary cement.Construction, as usual, should start from the corner.I spread 3-4 horizontal rows of concrete blocks and give them time to get to grips.It is from one hour to three or four, depending on the adhesive cement.
  2. At the junction of an extension to the house wall driven in linking mortgages.They use cutting metal rod or rebar diameter 8 -. 10 mm and a length of about 30 cm Rod driven into the wall to half the length of a protruding part of it should go to bed exactly at the seam between the blocks of foam.
  3. When erecting walls constantly check the horizontal rows and vertical design level and plumb.The last row of the wall is done taking into account the placement of roof beams for the roof.Perhaps make a gable or pent and cascading roof extension.

Exterior and interior walls of the foam

  1. foam itself has all the necessary technological properties for the construction of any building.When creating extensions of foam blocks, exterior walls need only a decorative wall covering.
  2. Exterior walls can be plastered, the solution adheres well to the blocks of foam and in the operation of the building is not showered.A good option - to finish construction of the siding.It all depends on how the outer coating facilities will be combined with the style of the main building.

Interior decoration is made, as in a normal house.Apply a layer of plaster, which is then puttied for painting or wallpaper.Consider options for interior decoration drywall or wood paneling.
