Which house is better

What determines the strength of the walls of the house?

There are two types of loads , acting on wall: vertical and horizontal.Vertical loads are the forces directed from the top down.Such load makes the weight of the walls, floors.Roofs and other structures upstream.

Since the low-rise homes, and wall building materials are a significant strength, the vertical load they can withstand fairly easily.

Horizontal and torques occur when wind influence at a pressure of soil on the foundation side, because of the cross-overlap and in some other cases.

horizontal load

have the most significant effect on the wall.If the wall thickness is small, it may cause cracks or deformation.That side and rotating the exposure does not lead to the construction of the walls of the individual thin.Resistance to compression of materials have enough to be reliable and quite small wall thickness, but the lateral force to increase the load size.

Walls House

on the reliability and stability of walls affects not only the thickness but also the design features of the building as a whole.With the help of reinforcement, connection of external walls with interior, creating a monolithic belts formed frame structure that helps to resist external influences.

Differences warm and energy efficient walls

considering how best to choose a house, a person chooses a place for itself with comfortable conditions.Every home is a shelter from the heat or cold, rain and other external factors.To be inside was comfortable, required to comply with three conditions.

1. temperature in the room should not be lower than 22 degrees Celsius.To maintain it at that level need extra heating in winter.Install furnaces, boilers, heaters

2. inner surface of the walls should also be quite warm - about four degrees less than the outside temperature.In this case from them will not pull the cold and they do not dampen, creating an unhealthy climate.To the warm walls, they must be made of a certain thickness according to the thermal characteristics of the material.

3. The construction of the wall should not be purged .The presence of crevices, which passes freely through the outside air will lead to significant heat loss.

wall structure with these characteristics will create a warm and comfortable environment in the room.However, energy-saving they may not be.Energy Saving Regulations require to reduce heat loss to a minimum.In this case, you need to make resistance to heat transfer at the walls is much higher.To this end, the wall thickness should be increased by almost half.But it is worth noting that in the private construction compliance with energy conservation is not necessary.

25Д0-25А2-25Д0-25Б5-25Д0-25ВС-25Д0-25ВФ-25Д0-25Б5-25Д1-2580-25Д0-25Б0-25Д1-2582-25Д1-2583-25Д1-2580-25Д0-25Б0-25Д0-25А1-25Д1-2582-25Д0-25Б5-25Д0-25БД-25Д1-258Б2

Reduce heating costs will comprehensive insulation .Increased tightness of windows and doors, insulated floor, basement, floors and roof.All this together can significantly reduce the overall heat loss and reduce spending on heating.

single or double-layer wall - which is better?

wall Modern materials allow to build a small wall thickness, but strong enough.At the same time money for the construction costs will be relatively modest.But the thin walls can not effectively keep warm.There are two ways of solving the problem: Select a multilayer or single layer wall.Under the multi-layer in this case it refers to construction, consisting of two layers or more.

In a first embodiment is constructed sufficiently thin load bearing wall, which is supplemented by a layer of effective insulation .Insulation prevents heat loss, and the wall provides strength.

insulate whether

wall In a second embodiment, in the case of single-leaf walls, originally used for construction materials, which have not only the mechanical strength but also low thermal conductivity .When wondering: what material is better to build a house, the most frequent answer is - cellular concrete .It has a large number of air cavities, which increases the resistance to heat transfer.However, materials intended for single-layer wall construction, outstanding features are no different.They have an average level of strength and heat engineering mediocre performance.To improve all the properties using various constructive ways.

Features single-layer walls

Some time ago, when we thought of something better to build a home for permanent residence, choose a material suitable for the construction of single-leaf walls.Wall thickness was selected so as to provide thermal comfort.At the same time energy saving matters were raised.

now build single-layer wall of only certain materials.They have a sufficient level of insulation , to ensure compliance with the standards of energy saving .

As a material for single-layer walls are widely used blocks of porous hollow ceramic, cellular concrete and macroporous claydite.They all have a common characteristic: low density in conjunction with a large number of voids.At a density reduction decreases heat conductivity but decreases mechanical strength.

Species cellular concrete there are several.They are different ways to the formation of pores.One of the best options for the construction of single-leaf walls is autoclaved aerated concrete.

Aerated concrete blocks have exact dimensions.It allows you to create a wall without gaps, with precise joints.If there are tongue and groove profile, it is unnecessary, and the solution.

There are certain advantages of single-layer walls that should be noted.This rapidity of erection, as one layer of material is placed more quickly than two or more.This wall can be cheaper because they do not require it to complement other components and labor costs while creating below.

Wall - monolayer - sectional

What better wall

There are also disadvantages of using single-layer walls.They always turn out wider, because it requires a certain thickness for optimal heat saving.As a result, we have to expand and foundation.

Since the number of seats laid jumpers, creating cold bridges, the construction of the building has to complicate.Various methods of heat places overlap, but do not work without a proper project.

masonry of the wall should be carried out as carefully as possible.The surface is covered with only a thin layer of decorative plaster.If there are significant irregularities, then hide them under a thin layer will not work.In addition to veneer plaster can be used for facades.

inside wall plaster or sheathe gypsum sheets.Decorative finishing can be any.

Multilayer wall Housing

Multilayer walls are made up of the main load-bearing structure and additional layers of insulation and lining. Carrier wall can be built from almost any material.Used bricks, ceramic and silicate, foam concrete blocks, and more.The specific choice depends on personal opinion a better house.Also you can choose for the construction of wood: logs or lumber.

Insulated walls erected from materials that have a higher density and mechanical strength.This allows the main supporting layer of small thickness.

When using masonry, the masonry is carried out with a solution.They fill the entire vertical and horizontal joints between the individual elements.

Much of the mechanical strength of the wall surface allows it to fix any construction and facing materials.

In multilayer constructions necessarily required wall insulation insulation , otherwise teplosohraneniya and energy efficiency level is quite low.This layer of insulation is responsible in this case for insulation.From its thermal performance it depends on how comfortable and warm house will be.An important indicator is the thickness of the insulation for the walls.The thicker the layer is insulated, the less heat penetrates through it.

most commonly performed insulation of mineral wool facade .This material is the most common due to ease of use and performance.Produced material and is in a roll form, but are used much more often slab of mineral wool for insulation walls.Another is actively used insulation is expanded polystyrene in slabs.

double-layer wall - sectional

have double-layer wall insulation located on the outside. Sandwich have a slightly different design.The insulated material which is in the center wall between the two layers of the base material.

If we consider the advantages of multi-layer walls, you should identify the following:

  • layer of insulation covers the cold bridges in the walls, which eliminates the need for complicated design;
  • bilayer thickness of the walls is less than that of single-layer, which saves on the foundation width;
  • can use any finishing materials, including ventilated curtain walls.

Replacement heater when to perform?

Over time, for insulating materials age, begin to deteriorate and lose their properties.In order to maintain a comfortable home conditions, you need to replace the heater.The exact replacement time is determined using energy audit .Shall be measured with the help of special equipment thermal and visual assessment is carried out.

Originally energy audit better to hold immediately after the construction of the house.This will provide data for future evaluations.After about twenty-five years of measurements are carried out repeatedly.If the thermal conductivity of the walls has decreased by one third or more, you will need to make major repairs including replacement of insulation.

Because in our country energy audits of homes has been held recently, the data has not been accumulated over many years.Rate insulation durability can only be based on indirect indicators.

What wall cheaper?

If we compare the single and dvuhsloynve odnikavymi walls with thermal parameters, the practice shows that the first type of construction is cheaper.But in this case it is taken into account only the construction of the wall.The gain in value is not so noticeable, given the need to bookmark a broader foundation.In addition, the thick walls of the space eat: or reduced floor space, reduced or free space area.

What better soundproof walls?

When chosen what is better to build a house for permanent residence, analyzed a variety of factors, including the level of sound insulation.In assessing sound insulation characteristics necessary to pay attention to the density of the material.The denser it is, the worse the sound carries.Therefore, the wall of heavy, dense brick will be better protected from noise than a thicker design of porous aerated concrete.

Coating - house

The same can be said with regard to insulation.Heavy mineral plates provide better protection against the penetration of sound than a light foam.

There are various ways to help make the walls more quiet.One way is to apply to the surface of the porous wall light layer of heavy mineral plaster .This approach will significantly reduce the number of penetrating noise.

wall structure also affects the sound insulation.The presence of slots in the thickness of the wall, parallel to its surface does better sound insulation.If the horizontal slit, leaving the surface and passing through the wall, the sounds will easily penetrate the

Since sound waves are refracted at the interface between two different materials, the double-layer and three-layer walls are quieter than single.Added to this, and most of their density.

What wall aesthetic?

Since the walls of any material are finished, their esthetics depends on the method and finishing features.Wall material impact on the beauty of a little.

For single-layer walls commonly used plaster .Three layers applied sequentially.It is a decorative top.It can be smooth or textured.

to dual-layer walls with insulation can also be applied plaster.In this case, a thin layer of special composition.Used acrylic, silicate and silicone, as well as many other varieties.

plaster surface can be painted with appropriate colors .

What better to build a house

popular options are clinker cladding materials , arrangement of ventilated facades and other finishing techniques.The beauty of the house depends on the finishing technique, the quality of the application or installation.

Environmental walls

All wall materials used for construction of houses, into the air harmful to humans.An exception may be only natural, no treated wood .However, in determining the environmental materials do not pay attention to the fact allocation substances and their amount.All construction materials have certificates, which indicate that there is no exceedances releasing hazardous emissions.

to walls of the house were environmentally friendly, it is necessary to comply with construction technology.As mineral wool may be a source of harmful dust.To exclude her from entering the house, the insulation should be on all sides to shelter and windproof vapor barrier film.

If we compare the two-layer and single-layer walls, the first polymer contains more, so they are less environmentally friendly.Polymers are aging faster than minerals, and are destroyed with the release of various substances.

to the house did not accumulate harmful substances, not enough to choose the most environmentally friendly materials.We still build quality ventilation .
