Heat flows naturally from a warmer to a cooler space. In winter, the heat moves directly from all heated living spaces to the outdoors and to adjacent unheated attics, garages, and basements - wherever there is a difference in temperature. During the summer, heat moves from outdoors to the house interior. To maintain comfort, the heat lost in winter must be replaced by your heating system and the heat gained in summer must be removed by your air conditioner. Insulating ceilings, walls, and floors decreases the heating or cooling needed by providing an effective resistance to the flow of heat
It is better to put insulation outside the load-bearing construction. In this case the “dew point” (zone at which vapour condenses) is situated in the thermal insulation layer and the load-bearing structures are protected from freezing and defrosting. Thus the working life of the building is essentially prolonged, besides, wall temperature inside the building is also increased. Placing insulator outside the load-bearing structure may be regarded as a compulsory measure( as per ECBC / NBC codes) , as it results in less usable space, worse microclimate inside the building (because of compulsory vapour insulation which prevents walls from “breathing”) and it is difficult to create a closed thermal envelope.
enercon products are extremely durable and inert in nature. It does not rot or decay like wood or other organic materials. The millions of tiny cells cushion buildings from major force, preventing progressive collapse.
Ordinary mason, labours with constructions tools can install; however special supervision is required to help them in maintaining quality, quantity, accurate lines and levels , wastages etc.
Yes, special chemical fabrocrette which is a single component fibrous copolymer admixture specially formulated to improve the properties . fabrocrette reinforced concrete/plaster consists of millions of fibers uniformly distributed throughout concrete /plaster to create a one-step micro-reinforcement system. These fibers stop micro cracks that can develop because of water loss and shrinkage , thermal movements , The growth of these cracks are blocked by the fibers thus ending the crack in the micro stage and providing higher tensile strength capacity , it increases the mechanical properties such as bonding (adhesion)with various building material , flexural, compression, and impact strength
Fundamentally, lighter the weight (density) will have lesser strength and vice-a vice, when compared to brickbats, ips , mud phuska, brick jelly etc., However INSULITTE concrete is designed with appropriate compressive strength, which can withstand normal foot traffic upon it.
INSULITTE concrete roof/ walls are insulated by millions of tiny air cells which reduce thermal conductivity. It acts as a heat resistant and reduces the cooling requirement of the building, thus saving the air conditioning need.
The INSULITTE concrete installed upon roof /wall provides exceptional acoustic/ noise insulation. Its porous structure and high surface mass, coupled with its ability to dampen mechanical vibration energy, greatly reduces outside environmental noise pollution and the indoor echo effect (i.e. reflecting sound) in empty rooms, providing a quieter, more comfortable interior for the occupants.
The INSULITTE concrete is extremely durable contains inorganic siliceous ash . It does not rust , rot or decay . it is rat , vermin , termites proof . it will not burn and is odour resistant.
INSULITTE concrete was designed and developed in 2004, and commercialized in full scale in 2006, completing significantly about 1 million sq.ft area Today INSULITTE concrete is used widely used and,is recommended by most of the architects, green designers, builders, because of its outstanding green features and cost benefits.
INSULITTE concrete can be used in various kinds of buildings, such as public facilities, industrial constructions, civil housing, hospitals, hotels, schools, stores, supermarkets etc.
Thermal conductivity is the property of a material that indicates its ability to conduct heat. The reciprocal of thermal conductivity is thermal resistivity, measured in kelvin-metres per watt. When dealing with a known amount of material, its thermal conductance and the reciprocal property, thermal resistance, can be described. When thermal resistances occur in series, they are additive. So when heat flows through two components each with a resistance of 1 °C/W, the total resistance is 2 °C/W. In practice thermal conductivity characterizes the energy saving function of the envelope construction.
This value will measure the capacity of a product to fight against heat loss. It will depend on thickness and thermal conductivity (lambda). The highest the R, the best performing the product. R combines thermal property of the material itself and thickness of the product and is calculated by dividing thickness (t) and lambda (?) value: R=t/?. The heat flow, going through the roof/ wall depends on temperature difference between inside and outside and thermal resistance R of the wall. Each element constituting the wall has thermal properties: bricks or concrete, insulation, rendering. Wall thermal resistance is the addition of thermal resistance of each components from interior coating to exterior rendering, and superficial resistances. With higher R, the wall will resist more to heat loss.
To put it simply, it is the measure of the rate at which heat is lost through a wall, for instance. As it is a measure of heat loss then the lower the U-value the better it is for your home comfort. It is the coefficient which characterizes the ability of the wall surface to heat transfer and is calculated as inverse of R value.
In order to ensure the expected energy savings, it is important that the insulation concrete like INSULITTE does not deteriorate, or settle, over time, as it is siliceous ash.
Fiber glass and rock and slag wool loose-fill insulations may settle approximately 1-3% resulting in virtually no impact on the thermal performance of the insulation. In contrast, cellulose insulation not only settles to a much greater degree (approx. 20%), but also at a higher rate. If cellulose insulation is being considered, make sure the installer understands that most cellulose insulations settle in attic loose-fill applications - that's a significant loss of insulating effectiveness.
In case of fire, the choice of insulation material can become a vital issue in terms of casualties, material or environmental damage. Combustible insulation can fuel the fire and cause it to spread. Some of the most widely used combustible insulation materials are oil-based foamed plastics (e.g. polystyrene, polyurethane or polyisocyanurate) and organic materials (e.g. shredded paper/cellulose). The less combustible materials are mineral wool which withstands more than 1000°C and fiber glass which withstands up to 600°C. For more combustive materials it is important not to install this type of insulation in contact with any area, which could become very hot during use such as chimneys, heater vents and steam or boiler pipes.
Air always contains some invisible water vapour. The amount of water vapour that the air can hold depends on its temperature - warm air can hold more water vapour than cold air. When warm moist (humid) air comes into contact with a cold surface, it will cool and may become saturated. If it cools further, some of the water vapour will condense out on the cold surface.
The type of condensation where moisture appears on visible surfaces within the building is called surface condensation. It may be seen to occur at times when large amounts of moisture are being produced in the house or room, especially during cold weather when windows and vents are closed.
Another type of condensation is interstitial condensation that occurs within external walls, floors and roofs. It occurs when warm moist air from inside the house passes through gaps in the internal surface and condenses at colder parts within. Since it cannot be seen, it is more difficult to identify. It may give rise to a damp, musty smell, and possibly mould growth on the inside surface. However, other causes of dampness can produce similar effects. Internally insulated walls with a deficient or damaged vapour barrier are particularly vulnerable to interstitial condensation.
Dew Point is the temperature at which condensations form.
Perm is a traditional unit of water vapor permeability, that is, the ability of a material to permit the passage of water vapor. If we want to keep things dry, we wrap them in something having low permeability. A material has a permeability of one perm if it allows transmission of one grain of water vapor per square foot of area per inch of mercury (in Hg) of pressure difference per hour. The value depends somewhat on temperature, however. At 0 °C, one perm equals about 5.721 x 10-11 kilograms per square meter per pascal per second (kg/(m2*Pa*s)) or about 0.2060 mg/(m2*Pa*h); at room temperature the equivalent is about 5.745 x 10-11 kg/(m2?Pa?s). [The SI unit, kg/(m2*Pa*s), simplifies to seconds per meter (s/m).] The lower the perm value, the better the vapor barrier.
Perm inch is a traditional unit of water vapor permeance. The perm value (see above) does not depend on the thickness of the material used as a water barrier. The permeance is the product of the perm value and the thickness, measured in inches. One perm inch equals about 1.453 x 10-12 kg/(m*Pa*s) at 0 °C or about 1.459 x 10-12 kg/(m*Pa*s) at room temperature. The SI unit kg/(m*Pa*s) actually simplifies to seconds(s).
The amount of water vapor passing through a given area of a plastic sheet or film in a given time, when the sheet or film is maintained at a constant temperature and when its faces are exposed to certain different relative humidities. The result is usually expressed as grams per 24 hours per square meter (g/24 hr?m2).
PIt depends on your geographical location. In cold climates, the vapor retarder should be installed on the inside (warm in winter) of the structure. In hot and humid climates the vapor retarder should be installed on the outside (warm side). Vapor retarders play an integral role in moisture control. Since climates are rarely cold or hot all the time, the vapor retarder should be placed to the side of the structure that is the predominately warm side. This is because heat flows from warmer to cooler in attempt to reach equilibrium. The warmer air can hold a higher amount of water vapor. As air cools, it can reach the dew point. This is the point at which the relative humidity reaches 100% and water vapor condenses from the vapor phase to the liquid phase. Therefore, the vapor retarder should be placed to the predominately warm side to prevent the moisture from migrating with the heat flow to the cold side, reaching the dew point, and creating a liquid moisture problem.
Thermal bridging occurs in small areas where the insulation level is reduced significantly compared with the remainder of the element.
VOC stands for Volatile Organic Compound. VOC's are any organic compound that readily evaporates into the atmosphere at room temperature. VOC's contribute to smog and certain health problems. VOC's often have noticeable odors and examples include gasoline, lighter fluid, caulks, sealants, adhesives, and paints. By utilizing low VOC caulks, sealants, adhesives, paints and other items in your home, you reduce the possibility of health problems and increase the quality of the air you and your family breathes.
