Instructions for insulation of frame houses with the help of foam and mineral wool

Prefab homes have become very popular for many reasons.Arguing that prefabricated houses have no advantage, it is meaningless.But at the same time, it should be noted that the frame construction is characterized by certain features that affect the technology in all phases of the work, some of which require special attention.

One of them - the building insulation.A distinctive feature of frame houses is that they do not have the usual, monolithic (solid) walls.In fact, the whole structure - a "box", which is sheathed with suitable materials, to the discretion of the owner.Hence, the increased requirements for installation "heat insulator".After all, the correct selection and its compliance with stacking technology depends largely on the indoor climate of the frame structure.

Features

• insulation covered with a layer insulation material shall be subject to all parts of the building (floors, ceilings, walls).
• Increased requirements for steam and waterproofing.
• choice of material for thermal insulation depends on the geometry and configuration of the load-bearing frame, beams position, poles, posts and the like.
• necessity of arrangement quality ventilation, and natural.
• Installing insulation material is both outside and inside (if necessary).

appearance on the market of various types of products for thermal insulation of buildings, greatly simplifying the process of thermal insulation work.Almost nobody uses the old "old-fashioned" methods, when used natural materials and improvised compositions.For example, a clay mixture containing straw, shavings, sawdust.But since each product its own individual characteristics, then there are some peculiarities in their styling.

Consider the most used insulation and the nuances of their installation.Note both advantages and disadvantages of materials.And it will start with the latter, taking into account the specifics of the work of self using simple tools.

foam

Disadvantages

• low mechanical strength.At the slightest exposure to the material bends, breaks, crumbles.
• It rodents like to settle, which will eventually destroy the plate.Consequently, the need to periodically engage in "dot" repair.
• If a strong thermal impact (fire) foam emits toxic fumes.
• Convenient for finishing flat surfaces.If they have a complex configuration (bends, twists and turns), it is better to use another heater.

Advantages

• Moisture does not absorb, although much depends on its density.Too loose, with a plurality of pores, capable of storing water.But if you make quality waterproofing, you can be assured that the heat insulation layer gets wet.The use of dense foam (Styrofoam extruded) eliminates the need to equip high-quality steam and waterproofing.Although it is completely not be ruled out, as the need for such protection is the rest of the building construction elements.
• low cost.Perhaps one of the cheapest options for warming.
• Easily processed (cut, sawed).
• Good "jamming" sounds.
• «Keeps" form, so it is suitable for the finishing of all surfaces (horizontal, vertical), as will "crawl".

technology

mounting feature is that the finished surface must be flat, otherwise the plates will have to do in a variety of "sampling" (indentations), and this is undesirable.The foam should fit tightly over the entire area of ​​the sheet.Typically

outside fits into 2 - 3 layers, depending on the climatic conditions in the region.The joints between the sheets (slabs), the easiest way to seal the mounting foam.It is necessary to pay attention to the joints of adjacent rows are out of place, or formed "through" the gap that will increase heat loss.

Laying begins below.fixation method - gluing.To do this, there are commercially relevant compounds.Glue is better to put a thin ribbon on the perimeter of the sheet, and in the middle - one drop.After clamping plate is secured efficiently.But to improve the reliability of fastening of plugs are used (plastic), which hammered at the corners.

Top superimposed reinforcing mesh, which is covered with a layer of putty.

Interior styling foam layer is carried out by the same procedure.It is necessary to consider one caveat - the thicker the plate, the more they "conceal" a useful area.With respect to the one wall component is small, but in the aggregate can be up to a certain value.

Mineral wool

worth noting that quite often used stone wool produced on the basis of basalt rock (its characteristics are described in detail here).But she has a "minus" - it is impossible to compress.Therefore require very precise adjustment of the size, therefore, will increase labor costs.Use of glass involves additional difficulties in installation, in particular measures to protect the skin and respiratory tract dust from it.

Therefore, it is advisable to use mineral wool.However, we must bear in mind that working with ecowool requires some training.

For quality mineral wool insulation density must be at least 30 kg / m3.Better (more convenient) to use a material in the form of plates, rather than rolls.Thickness - 50 mm.

Disadvantages

• main - increased water absorption.This leads to stringent requirements for waterproofing.

Advantages

• high vapor permeability.
• Virtually "shrinks" during operation.

technology

total thickness of "insulation" is usually 10 cm. Therefore, installation is carried out in at least two layers, offset joints between slabs.They put "vraspor" between the structural elements (pillars).The material is compressed a little, and after laying, increasing in size, is fixed tightly to the landing site.

Unlike foam, sealing joints produced reinforcing tape.In this regard, warming process simpler.

General recommendations

• foam - dense material, so it does not give the possibility of the walls to "breathe."Vata - are absorbent.On this basis, the issue of natural ventilation - one of the primary.
• for excellent waterproofing material such as asphalt.But between him and the insulation must be a gap (air space for ventilation).
• To reduce the amount of work associated with the processing of the material, you need to pre-determine the size of the plates.Accordingly, the frame and mounted with the necessary spacing between the columns (by product width).
• for quality protection of the foundation better use of permanent formwork, which is assembled from slabs of the same extruded polystyrene foam.He also serves as a form for pouring, and isolator (hydro and thermal).

Conclusion

you can find a variety of opinions about the quality of insulation of one or another material.One and the same "heat insulator" someone can praise too, and someone does not like it.Here you need to understand the following.

First , much depends on the "products" right choice.It should first of all focus on the conditions in which it will be operated.

Second , quality thermal insulation depends on the integrity and professionalism of employees.After all, ill-considered actions, technology, violation and irresponsibility can spoil everything.

Before you choose the appropriate material, good advice from people who are already living in the frame home, and most importantly - built with her own hands.Their assessment, given the applied insulation, the objective will be enough.You can read the material on warming the house from the outside, which describes such work.

There are cheaper options - filling the gap between the walls expanded clay, sawdust, even straw.But here, everyone must decide for itself, considering the following aspects:

• walls are obtained thicker;
• maintainability - the "zero", since the need to dismantle the entire structure;
• except expanded clay, all other materials quickly become wet.

We have indicated only the main aspects of the work on warming.But the wall is a frame house - it is "pie", which, in addition to the insulation, there are other layers (hydro, steam).It is therefore necessary to examine the features of their arrangement, as well as criteria for the selection of appropriate materials.
