Regardless of what material the house is built, the process of insulation of the structure is attended. Given the characteristics of the climate of our strip, start from the bottom of the house, that is, the foundation.

When to warm the foundation?

The easiest way to perform works on the insulation of the base in the process of building the building. But, quite under the power to create an additional layer and during the operation of the finished design.

Why insulate the foundation?

Among the causes of the foundation insulation, we highlight the following most important:

1. Efficiency. The profitability of such a solution is shown to reduce the cost of heating the building during the operation. In the absence of this layer, the cool air is lifted from the ground extends inside the building, lifting up and eventually accumulates on the roof. The main indicator of this - thawed snow on the roof. Thermal insulation foundation prevents the penetration of cold air flows into the room.
2. Conservation of structural strength. Moving the chilled air from the bottom upwards favors the formation of condensate on the surface of the frame homes due to temperature changes. This, in turn, causes the premature destruction of materials and affects the duration of the operation.
3. Adjusting the indoor climate. Due to obstacles penetrating into the building chilled air flow when the temperature drops outside, the climate conditions are at the appropriate level, without significant changes.
4. Expansion of usable area. While insulating the basement, cellar use case becomes much more. This is not an abandoned room and not the warehouse under hozinventar or trash, and a full basement, equipped, for example, a gym or a swimming pool.

What are the technology of warming?

There are two main options for insulation, each of which offers its own advantages:

• internal
• Outside.

Advantages outer Technology

• Basement protection
• Prevents the penetration of the chilled air inside the building
• Protection frame houses from premature failure
• Warns frame deformation
• structural core protection at home from the effects of groundwater
• Prevents sudden temperature changes in the basement of the manifestation of such conditions outside
• Life extension.

Advantages of internal technology

• Climate control in the whole area of \u200b\u200bthe house
• Obstacle condensation
• Saving energy expended on heating buildings.

Which material you choose?

The modern range of construction materials provides plenty of options for insulation, in particular for arranging the foundation. But, despite this, demand is constant foam.

Why is it the best option for the foam insulation of the foundation?

Often the choice of foam insulation to the basement and other parts of the building structure is quite understandable. This material is characterized by a number of advantages and can significantly save on the process of resettlement of insulation.

Benefits of foam

• High rates of heat saving
• A light weight
• Affordable price
• Environmentally friendly material
• Does not absorb moisture
• Does not deteriorate, regardless of the service life
• Easy installation
• Not destroyed when exposed to many chemical compositions.

What foam plastic to choose for the insulation of the foundation?

All parameters of the production of foam are regulated by the standards of GOST 15588-86.
Pay attention to the following parameters when choosing:

• density
• thickness
• length and width of the plate.

For the insulation of the foundation, the polystyrene foam is most often used by plates 100x200 cm, the thickness of which varies in the range of 5-10 cm, and the density indicator is at least 50 kg / m3.

Important! The thickness of the foundation insulation directly affects the heat conservation indicator in the building, but do not forget that the excess ledge of the base behind the wall line is not recommended.

What foundation should be insulated?

Note that the material mounting technology is determined by the type of foundation:

1. The insulation of the screw foundation due to the design features is not required. Explanation Simple: Supports are located at a sufficiently high level over the ground, which prevents the penetration of the cold from the soil into the house. The only option that can be used with increased comfort requirements is the insulation of the floor from the inside.
2. With the insulation of the pile foundation, only the upper beams and stoves are exposed to the processing. In this case, it is necessary to create a preliminary waterproofing layer. Metal welds themselves do not need an additional protective layer and do not contribute to the transmission of cold to the surface.

   
3. The insulation of the belt foundation is quite substantiated and performed along the outside with the moisture created in advance.

Important! All these methods are applicable in the construction process.

If, when designing and building a house, the thermal insulation of the base was not fulfilled, then the insulation of the basement basement is issued.

Warming of the foundation outside

The whole process consists of a sequence of several stages:

• Preparation of instruments and materials
• Preparation of soil
• Preparation of the surface of the foundation
• Installation of insulation material
• Finishing, decorative work.

Instruments

To perform the insulation of the foundation of the foam, prepare the tools and materials listed in the list:

• Plates of polystyrene
• Shovel
• Perforator
• Drill or mixer
• Hammer
• Level
• Sand
• Gravel
• Primer
• Plaster
• Putty
• Plastic buckets
• Glue for foam
• Spatulas (gear and smooth)
• Emery
• Paint rollers and brushes
• Knife
• Mounting foam
• Fiberglass 2.5x2.5 mm
• Waterproofing material (liquid rubber, anti-condensate film)
• Mounting foam
• Dowels Mushrooms
• Profile corners made of metal.

Fundament insulation scheme

Before starting work on the arrangement of the foundation, consider carefully this scheme:

Preparation of soil

This process will not require almost no costs except energy.

Sequencing:

1. Drop the trench around the perimeter of the building of the following dimensions: depth - 1.5m, width - 40-50 cm.
2. Failure the ground at the bottom of the ditch.
3. Put sand.
4. Match.
5. Make a temporary boardwalk flooring at the bottom of the trench for the convenience of work.

Important! Recommended thickness of the stacked sand layer at the trench bottom - 20 cm.

Preparation of the surface of the foundation

Sequencing:

1. Clean the remnants of the soil and other contaminants on the vertical surface of the building.
2. Scroll.
   

   Important! Apply primer mixtures of deep penetration.

3. Wait for drying.
4. Create a waterproofing layer, for example, liquid rubber.
   

Principle of installation of foam

Important! Some experts recommend creating a double layer of insulation with the dispersion of the joints, but others insist on choosing the material of greater thickness with increased heat conservation requirements, since the dual "pie" can eventually stratum and lead to the unpleasant consequences of moisture accumulation inside.

Fundament insulation technology:

1. Make the markup of the upper limit by drawing a line by level or pulling the cord.
   

   Important! The top markup of thermal insulation should be at least 2-3 cm overlapping the waterproofing layer or rise above the ground level by 40-50 cm.

2. Prepare glue according to instructions on the package.
3. Apply the adhesive mixture to the base surface.
   

   Important! Installation Start from the bottom row, from the corners of the building.

4. Set the first row of foam in the horizontal direction, speaking each plate at 5 cm into the sand pillow.
   

   Important! Perform work sequentially, since the speed of drying is high enough.

5. Installation of several subsequent follow with joints offset.
   

   Important! All boards should fit tightly as possible to each other.

6. Wait for a reliable adhesion of the material to a surface.
7. Fill in all the gaps with foam.
8. Level the surface, remove the excess.
9. Prime with the surface.
10. Wait for drying.
11. Make cuts on fiberglass fragments corresponding to the parameters of the foam boards.
12. Prepare a solution of the adhesive.
13. Apply the adhesive to the surface of the foam and pressed into it reinforcing mesh.
14. Quickly smooth out the whole piece of mesh.
15. Put another adhesive layer (protective) over the reinforcement mesh thickness of 2-3 cm.
16. Wait for drying.
17. Zashpatlyuyte surface.

Completion of the foundation insulation

Completion - a ground clearance and the decoration of the surface of the cap.

Sequencing:

1. Coat the surface of the insulation another layer of waterproofing, e.g., anti-condensate film.
2. Make another sand bed.
3. At the bottom of the trench put foam slab whose width coincides with the width of the channel.
4. Sprinkle the top 30 cm of sand or gravel.
5. Match.
6. Attach the corners and along the upper horizontal line foam metal profile corners.
7. Perform side surface facing the foundation (top of the foam) brick. This approach will provide additional structural strength, but the effect is not required.
8. Fill the trench with soil.
9. Match.
10. Apply the plaster on the raised surface of the foundation.
11. Sand the surface.
    

    Important! Sweep to make dried up, but not completely hardened solution.

12. Wait for drying.
13. Repeat the procedure for plastering and smoothing.
14. Color base surface or to place any selected covering material.

Internal insulation foundation of the house

While insulating the basement from the inside, follow similar steps to clean up the surface mount foam, final works and decorative design of basement space. Insulation technology foundation is identical, but with no ground. Please note, despite the similarity of the whole process, there are some features.

Important! Notice The following differences finishing process.

Pre-cleaning surfaces

1. Pay attention to possible irregularities and cracks on the walls.
2. Align all the surfaces of the walls and remove the defects by means of a primer.
3. Repeat the procedure twice, keeping dry periods.

Important! It does not require the creation of a waterproofing layer.

Mounting foam

1. Arrange the second type of fixing after closure gluing foam.
2. In the joints and in the middle of each fragment foam drill.
3. Fasten them dowels mushrooms.

Important! This technology is not used in the outer insulation of the base to avoid damage to the outer sealing layer. To clearly understand the principle of attachment check below attached video.

Conclusion

The whole process of heat insulation of the foundation simply and quite able to perform with his own hands. This allows to obtain additional financial benefits when used for foam operations. But, despite such apparent availability of technology, observe at all stages of the work instruction requirements. Only under these conditions you have created indexes insulation layer will correspond to the desired level.
