Insulation for your home

The house in which we live, must be comfortable. In winter it should be warm, and cool in summer. Such thermal comfort can be achieved only if the interior of the house protected from the vagaries of weather decent, heat insulating materials.bar in troy michigan |

To reduce heat loss in buildings and structures are widely used special insulating materials, which are of low thermal conductivity, low gravity, are made in the most user-friendly manner and sold at an affordable price. For example, glass wool produced in the form of long soft mats. They are easily cut an ordinary knife, when laying practically no waste. These materials are resistant to atmospheric influences, and some of them are not destroyed even during prolonged stay in the ground or in water. The porous structure of the insulating material reduces the sound of their permeability. Especially popular among the specialists using mats and plates of thin glass fibers (4-5 microns in diameter).

To reduce heat loss in buildings and structures used insulating materials of mineral wool and extruded polystyrene foam with low thermal conductivity and low weight.

Thanks to these properties mats and plates of fiberglass is almost universally used for thermal insulation of roofs, attics and floors, walls, and floors in buildings. All products are made of fiberglass do not burn or burn very badly.

Fiberglass mats are produced in the form of long strips of different thickness and width. They have a density 10,5-25 kg / m3 and thermal conductivity of 0,038-0,047 W / m2(depending on the brand of product). To improve efficiency in conditions of considerable parovydeleniya or weathering mats sometimes Kashira (covered) with aluminum foil (on a paper substrate) with canvas or fiberglass.

Equally convenient and manufacturability of the rectangular glass plate. They are more dense (13-85 kg / m3) And less elastic than the mats, but better keep their shape and not so prone to vertical strain. The thermal conductivity of plates from 0,032 to 0.0420 W / m2, That is even slightly better than the mats. Besides the usual slabs of fiberglass, adjusted industrial production of hydrophobic (water repellent) plates, and plates, laminated fiberglass canvas and aluminum foil. Blankets, like the lighter products, are useful for insulation of attics and lofts. Plates of glass slightly heavier, so often used for insulation of floors, basement ceilings, internal partitions and exterior walls.

Quite unique properties have insulation panels of extruded polystyrene foam. They are made of foamed polystyrene and carbon dioxide differ very low thermal conductivity (0,025-0,035 W / m2), Which remains stable not only in terms of atmospheric moisture, but also by direct contact with water. Density 35-45 kg / m3The strength characteristics of 30-50 t / m2with 10% linear strain.

Properties of insulating materials

It has a relatively high deformation-strength characteristics.

Maintains insulating and mechanical properties under cyclic temperature changes.

Not destroyed in contact with soil and plants.

Refers to the slow-burning material and does not support the combustion process.

Environmentally-friendly, as it contains in its structure of freon.

It is used to stabilize the temperature regime of basements of buildings and protection from freezing their foundations, insulation of walls and basements of buildings to reduce heat loss through their underground elements. Because of its high strength and very low thermal conductivity of extruded polystyrene foam boards are the perfect insulation material for the floors to the ground, floors over cold basement for so-called "warm floor with forced heating. As well, these boards and in other cases - for example, in thermal insulation of roofs, attics and floors, to prevent swelling soil under the foundations of buildings.

Most insulation requires elements of buildings and structures that are more complex configuration. First of all, this applies to pipelines of hot and cold water supply and ventilation systems. For such purposes are made of special glass products in the form of cylinders and season (plate) of mats of different sizes. Heat insulating cylinders, mats and slabs technical purpose Kashira aluminum foil and with glass to make these products the necessary strength, ability to protect from moisture penetration and weathering.

Mat of mineral wool, laminated foil.

However, insulating materials, particularly fiber, always use special films and coatings designed to protect these materials from moisture, blowing by air and for sealing joints of individual elements of heat insulation layer. Without such protection for wet or scavenged parts of the insulation produced so-called thermal bridges that contribute to excessive losses of heat.

Parobarernye film (vapor barrier) insulation materials to protect from moisture, which condenses from water vapor in the atmosphere over the warm room. Superdiffuzionnye films prevent insulation from wetting water coming from the outside (usually the precipitation). They are good gidroizolyatorami, but at the same time have the ability to pass water vapor formed inside the premises or in the space between parobarerom and outer fence of the premises (wall or roof).

Same ability to pass water vapor and wind-proof coatings possess, but their main task is to prevent through-blowing thermal insulation barrier. Parobarernye film (insulation) and wind-proof coating may be applied to the fibrous insulation materials at the stage of their production (in aluminum foil and lamination with glass), which greatly enhances productivity when performing construction work.

The outer insulation of walls of buildings and structures is always preferable to internal, as it prevents the freezing of these walls in the cold season. However, sometimes there is a need for heat insulation of the wall. If it uses the inner lining of gipskartona to the metal frame, then the intervals between the frame profiles appropriate to lay fiberglass mats or slabs density of not less than 15 kg / m2. When arranged in no additional fasteners. Prirezku mats or slabs of the place should be made with a margin of 2 cm from each side to ensure a tight seal to their frames and structures among themselves.

Before the thermal insulation of plasterboard should provide parobarer - pull water resistant film or used for insulation mats (slabs), Laminated aluminum foil. If you do not, then a pair of water infiltrated from the premises, will condense on the cold surface of the wall and moisturize the insulation, thereby worsening its insulating properties. When a well-fitted thermal insulation and vapor-proof film are stacked, can be sewn on rack metal frame drywall sheets.

Parobarernaya film plank pop insulation.

For insulation of pitched roofs used hydrophobic fiber mats and slabs density 15-20 kg / m2 (the higher the slope of the roof, the higher should be the density). They can also be drained aluminum foil. Fitted at the place mats or slabs are stacked in the intervals between the rafters or beams of the frame. Additional mounting with no need because of the elasticity of the material.

On the inner sides of the insulation on the underside of the rafters strap attached vapor-proof film (if the heater is not laminated foil). Her joints are tightly connected with duct tape. The outer sides of the insulation on the top of the rafters or beams of the frame under the ledges outside crates fit waterproofing. To fiberglass mats (slabs) will never get wet, between them and waterproofing should be created ventilated gap of 2-4 cm, and waterproofing should never come into contact with these mats.
