Why is insulation of floors?

Floors play an important role in keeping the heat inside the buildings. In a typical home heat loss through the floors without insulation may reach 20% of the total heat loss, as through uninsulated floors heat is transferred into the soil in an unheated room and into the surrounding space. In addition to reducing heat loss, insulation floor allows more efficient use of heat. Obtained thus saving energy helps to reduce both the cost of heating and environmental pollution. The temperature at the surface of the floor is the main factor determining the degree of comfort of the room. Temperature conditions of the human body requires that the temperature on the inner surfaces of the room was not lower the air temperature inside the building for more than 2 °. If we consider that the cause of the loss of about 50% of our body heat is the heat generation becomes Floors play an important role in keeping the heat inside the buildings.

Temperature conditions of the human body requires that the temperature on the inner surfaces of the room was not lower the air temperature inside the building for more than 2 °. If we consider that the cause of the loss of about 50% of our body heat is heat radiation, it becomes clear that these losses are primarily determined by the temperature of building structures such as walls, floors, stoves, etc. When designing the sexes can not forget about the possible condensation of moisture on low-surface floors, and bridges in cold places conjugation walls and floors. Consequence of the condensation may be the appearance of fungal organisms and molds, with devastating force at the building construction and have an adverse effect on health are in a room of people. The most effective way to deal with these adverse events is a competent design and careful implementation of thermal insulation of the sexes. Optimal results are achieved while in those cases where, along with insulated floor there is the possibility of isolating mating with a floor basement walls, basement, circular beam, etc. From the above conclusion that the floors of dwelling houses located in close proximity to the ground in contact with the outside air, or separating heated space from unheated, should be insulated. This allows you to simultaneously achieve three objectives: to reduce heating costs, improve comfort and shelter to reduce pollution of the environment. In addition to housing, Floor insulation can be very useful in the construction of other types of buildings. Materials used for insulation of floors exposed to high loads, which is why among the requirements imposed on them in the first place should be called a high compressive strength and low degree of deformation in compression. Other important characteristics of insulating material to reduce to a minimum thickness of the building structures are low thermal conductivity and ability to keep the original parameters of the thermal insulation for virtually unlimited periods of time even when exposed to moisture and mechanical loads. Insulating material should be easy to use, it means - its ease of cutting, ease and speed of installation with a small amount of waste, which minimizes the cost of the thermal insulation. v Extruded polystyrene has all of the above properties. Due to its zakrytoyacheistoy structure, this material is different, long-life and provides an efficient and economical solution to insulation floors exposed to different loads during the operation when performing various functions. Heat insulation of floors the first floor. Advantages of extruded polystyrene are particularly apparent when insulation laid directly onto the ground plates of the first floor, as they allow us to make a choice between several design decisions. Along with saving thermal insulation and lower the cost of work, these design decisions provide thermal insulation, the effectiveness of which remains high even when operating in extreme conditions. On the other hand, how reliable would not be insulated floor, it is insufficient without an equally reliable insulation matched with a floor basement walls, basement and other structures. Thermal insulation of underground structures is of particular importance in the presence of the construction area of ??aquifers and groundwater. Given the excessive moisture, low temperatures and mechanical stresses utmost importance is the optimal choice for each case insulation material. Extruded polystyrene plates provide perfect technical solution to the problem wall thermal insulation of basements and protection of the waterproofing membrane. Excellent material for isolation of ring beams and the cap is Styrodur ® 2800CS, corrugated surface of the plate which is ideally suited for plastering and finishing works, providing good traction finishing layer to the base. By virtue of its structure zakrytoyacheistoy extruded polystyrene foam does not absorb moisture and have an exceptionally high resistance to bending and compression. As a result, they can be placed under the waterproofing membrane on a solid foundation of coarse gravel with a leveling layer of sand. Not recommended unit of the underlying layer of thickness less than 10 cm This solution eliminates the need for concrete preparation. Being on the warm side of insulation boards, the membrane also serves as a steam insulating layer. From the viewpoint of building physics, this design is much superior to the traditional type design. The thickness of the distribution plate, which serves as the basis for the finished floor shall be not less than 8 cm strip of elastic material, arranged along the interface wall and floor, not only is the seal expansion joint, but also improves the sound and vibration isolation. Laying bituminous waterproofing membrane over the insulation is made by cold bonding, while in the adhesive should not be organic solvents and plasticizers. In the case of moderate soil moisture and moderate moisture out of it, and depending on the functional significance of the building, for the separation layer is fairly one-or two layers of thin plastic film, with a minimum overlap of 15 cm insulation floors of basements. Underfloor heating first floor. When construction on the moist ground, and depending on the purpose of buildings and sizes of loads, thermal insulation of the heated floors of basements by the scheme adopted for load-bearing floors first floor. If there is pressure created by groundwater, and also depending on the loads generated by walls and columns, insulation extruded polystyrene foam can be placed both above and under concrete slabs, stacked on the tarmac. When laying slabs of extruded polystyrene foam under the concrete slabs and basement walls for thermal insulation of basements with slabs of extruded polystyrene foam creates a reliable and durable thermal insulation of basements, which differs in that it has no heat-conducting bridges, and which enables the use of the heat capacity of bearing structures. Since the capillary water absorption of extruded polystyrene foam is missing, boards can be installed under the waterproofing membrane on the underlying layer of gravel, which saves money for the construction of the base. In the presence of the concrete base waterproofing membrane can be placed both under and over the insulation of extruded polystyrene foam, and both solutions are correct. If the membrane is laid on a concrete foundation in accordance with the traditional method, extruded polystyrene protects the membrane from mechanical damage during construction and provides a reliable surface for laying the foundation slab. With heated floors and first floors to minimize heat loss is recommended to consider increasing the thickness of the insulation of these floors. Location and mounting of heating pipes is partially dependent on placement of the waterproofing layer. If the waterproofing membrane is located under a layer of extruded polystyrene foam, tubes can be fastened directly to the insulation boards, as the use of sufficiently flexible heating pipe fasteners do not damage the high-insulating boards. Between the insulating layer and a coupler, which serves to maintain and heat radiation, it is necessary to put a thin film of polyethylene, which serves as a gasket and steam insulating layer. If the hydro-or vapor barrier membrane placed over plates of extruded polystyrene foam laid on compacted gravel foundation with a large, heat pipes can not be attached directly to insulation, because you can not forget the need to ensure a continuous waterproofing. To solve this problem, use an additional layer of material such as wire mesh reinforcement, etc. In-floor heating is necessary to pay special attention to the implementation of expansion joints. In addition, you should take all measures to avoid the formation of heat-conducting bridges in the joints between the slabs. Thermal insulation floor mezzanine. Placing insulation under the concrete slabs. The most effective way of thermal insulation of concrete slabs in contact with outer space or are in unheated rooms (basements, manholes, hatches, arcade, voids and cavities of official purpose) is laying insulation beneath these slabs. Such a constructive solution is in full accord with the laws of building physics, since, being laid on the cold side, heat insulation eliminates condensation, increases the use of the heat capacity of concrete slabs and reduces temperature swings within the building. When using monolithic concrete slabs are best used extruded polystyrene grade Styrodur ® 2800CS. Slabs from this material are laid in the formwork. Due to its corrugated surface they have a high degree of adhesion to concrete. If concrete is well compacted, the adhesive force is so great that for fixing insulation boards do not require any additional mechanical components and accessories. Rain water contained in concrete moisture and mechanical stresses that occur during construction, do not reduce the high thermal insulation properties of panels made of a material Styrodur ® 2800CS, which explains its minimal water absorption and high compressive strength. Insulated surface can be plastered or covered by a facing material. When stucco exterior surfaces must use appropriate equipment that is also recommended during the plastering work indoors, especially when it comes to large areas. When insulation precast concrete projects under construction or concrete slabs of existing buildings insulated from the material Styrodur ® 2800CS attached to the outside of the concrete slabs with cement and / or fasteners. For surface finishes can be used stucco and various facing materials. Laying insulation on top of concrete slabs. If you can not lay insulation layer on the bottom floor mezzanine, and without the need for maximum utilization of the heat capacity of thermal insulation of concrete slabs placed on top of these plates. Due to its high thermal insulation properties even thin slabs of extruded polystyrene insulation provides an effective equality. If you need to enhance sound insulation problem is successfully solved by the use of extruded polyethylene foam sheet (eg Foamisol ®), which can be installed both above and under the insulating layer. To prevent heat - conductive bridges is important to correct profiling of the edges of insulation boards. Heated floor mezzanine. In the presence of underfloor heating insulation of the sexes is an absolute necessity. The role of insulation in this case is to reduce the emission of heat energy in unwanted directions from the thermal storage and radiant layer in which the heating pipes are located, what rises to the maximum efficiency heating system. Due to its high mechanical strength and excellent thermal insulation properties, insulation made of extruded polystyrene foam is exceptionally effective, even when laying thin layers (from 2 to 4 cm), with the calculated thermal insulation parameters and initial thickness of the material remain unchanged. If the heating pipes have a fairly high elasticity, then the use of extruded polystyrene foam is not necessary mounting pipes with a wire mesh, which reduces the thickness of the screed. Between the insulation and the screed must put a layer of plastic film, which creates a barrier to moisture in the concrete. To ensure the acoustic soundproofing layer is laid on concrete slabs, and on top of it is placed insulation, extruded polystyrene foam. For sound insulation is recommended to use a layer of material Foamisol 5 mm thick. Along the interface of concrete slabs and walls need insulation placed vertically, which is created by bending up the layer of insulation and installation of strips of insulating material. Heat insulation of floors made of dry technology. Typical problems in the insulation of existing floors is during reconstruction, is the lack of height of the room or the inability to bear an additional burden plates from the isolated floating floor with a concrete screed. Thermal insulation made from extruded polystyrene foam slabs stacked on top of a flat surface has enough carrying capacity for making thin, lightweight floor using only dry technology. Clean the floor should not be laid directly on the plates of extruded polystyrene foam. The most common solution is laying on top of slabs of extruded polystyrene foam Particleboard (Chipboard) with a minimum thickness of 18 mm as a reason to clean floor. Particleboard should be interconnected at the edges with slots and grooves ('a tongue') in order to achieve a monolithic structure. On the floor area with the expected higher point loads use insulation with higher strength characteristics to help avoid uneven defoplatsii coverage. For damp locations must use moisture-resistant chipboard. In the floor the first floor device shall be provided a vapor barrier of polyethylene film thickness of 0.2 mm laid between the insulation and particleboard. If necessary, the device effective sound insulation, you can put a layer of material Foamisol ® 5 mm thickness. Source: Portal Know-House.ru
