As we know, climate change is one of the major industrial challenges of our time- industries, science and politics are called upon to slow down any further rise in greenhouse gas emissions and use available resources more efficiently. Faced with these facts, various ideas and strategies for sustainable protection of the environment and climate, for the future, have been put forward.

• A key approach is IMPROVING THERMAL INSULATION in buildings; a concern for all (governments, industrial houses, cooperates, developers and property owners) is energy conservation measures and costs entailed.
• The Future therefore will be larger collective efforts towards achieving energy goals, adhering to directives and taking small to large steps to conserve energy.

In most countries, buildings use one third of all energy consumed and two thirds of all electricity (summer and winter). Due to the high energy usage, buildings are a major source for pollution that reduces urban air quality and adding pollutants which directly, or, indirectly contribute to climate changes.

• Energy consumption in buildings accounts for 49 percent of sulfur dioxide emissions, 25 percent of nitrous oxide emissions, and 10 percent of particulate emissions.
• Understanding how heat is transferred, how heat is gained in buildings, and how we losing heat in winter, is essentials for making the right insulation choice.
• AEROLAM™ provides you with a unique opportunity to understand heat flow while considering your location, climate and purpose.
• With better understanding about heat, we, the customers can make better choices. In our world, better choices will have positive effect on our environment, our comfort level our energy bills, and our future existence in this wonderful world!

General:

Heat: Heat is transferred in 3 ways: Conduction, Convection, and Radiation.

In summer, or, in hot climates, majority of heat transferring through building envelop in form of Radiation Heat.
Correct design, including suitable insulation selection eliminates the black globe effect and reduces to minimum possible heat stress phenomena.

• This will increase farm yield and reduce operation costs.
• AEROLAM™ products were designed to block 97% of incoming radiation heat, using multi pure aluminum foil technology incorporated with low K air cavities.
• Livestock buildings require special attention. Aside from animal comfort, which is important matter for itself, insulation has direct effect on farms yield, profitability and pay back time.

General
Heat is transferred in 3 ways: Conduction, Convection, and Radiation.

In winter, or, in cold climates, our primary concerns will be with heat loss. Convection and Radiation are equally responsible for heat loss. AEROLAM™ products reduce heat loss via all heat loss channels.

• AEROLAM™ will help to reduce heat loss as well as induce better and even distribution of heat from brooders or other heat elements used to heat-up the air.
• In existing buildings, it is wise to add AEROLAM™ (retrofit) to pre-made insulation systems (mostly bulk system). Adding AEROLAM™ will reduce running costs and will improve overall animal comfort, resulting with better yield.

Lambda or Thermal Conductivity value
Defines a materials ability to transmit heat. The Lambda is a given figure, there is a table of Lambda values in the building regulations part L.

Every material has its own Lambda value. The lower the figure the better the performance.

Unit of Measurement
W/mK

R-Value = Thermal Resistance
Defines a materials ability to resist heat flow. The higher the figure the better the performance.

Unit of Measurement
m2K/W

To calculate the R-Value:
Find the Lambda value (table in the building regulations, part L or on the packaging of the material).

U-Value
Defines the ability of an element of a structure to transmit heat under steady state conditions. The lower the figure the better the performance.

Unit of Measurement
W/m2K

To calculate the U-Value:
Divide 1 by the R-Value

Example:
100mm Polyflat
1 / 4.348 = 0.22
U-Value = 0.22

Reflective insulation products incorporate trapped air spaces as part of the system. These air spaces, which may be layered or closed-cell, can be included in the system either when the product is manufactured or while it is being installed. In either case, the advertised performance of the insulation requires that these air spaces be present after the product is installed.

• The labeled R-values will not be achieved if the product is not installed according to the instructions of the manufacturer.

• The thermal performance of the reflective system varies with the size and number of enclosed reflective spaces within the building cavity.
• Most reflective systems range from one to five enclosed air spaces.
• There are other beneficial considerations for using reflective insulation. Generally, these products have a very low water vapor and air permanence.
• When installed properly, with joints taped securely, reflective insulation materials are efficient vapor retarders and an effective barrier to air and radon gas.
• Since reflective insulation materials are effective vapor retarders, care should be taken to ensure that they are installed correctly within the structure.
• Correct installation depends on the climatic conditions and moisture sources involved.
• An appropriate installation ensures that all joints and seams are butted against each other and taped, or overlapped and taped. This will reduce the possibility of moisture condensation within the cavity and improve performance.

Useful Definitions for Understanding Radiant Barrier and Reflective Foil Insulation Products

• Emissivity: The ratio of the radiant heat emitted by a surface. ALL materials have emissivity's ranging from 0% to 100%. The lower the emittance percentage of a material, the lower the amount of radiant heat radiated from its surface. The naturally low emissivity property of aluminum facing an air space results in very low emittance of heat from itself; it does not radiate much of its own heat from itself. This naturally low emissivity property makes aluminum ideal for use in radiant barriers.
• Flame Spread: Indicates the relative rate at which flame will spread over the surface of a material, as compared with flame spread on asbestos-cement board (rated 0) and on red oak (rated 100).
• Radiant Barrier: Per the Department of Energy (DOE), a product classified as a "radiant barrier" must have a high reflectance of 90% or more and a low emittance of 10% or less. If it doesn't reflect at least 90% of the radiant heat, it cannot be called a "radiant barrier."
• Reflectivity: The reflectivity property of reflective surface facing a heat source across an air space allowing the aluminum to Reflect radiant heat back to the direction from which it came. Represented as a percentage.
• Smoke Development: A measurement of the obscuration of light by the combustion product stream.
• Tensile Strength: The stress at which a material breaks or permanently deforms.
• Wall Plate: Sometimes known as the top plate or ceiling plate, the wall plate is typically a 2 X 4 that is nailed along the top of the wall studs forming a wall.

 

Other Details:

 

• Radiant barrier foil insulation is a reflective insulation system that offers a permanent way to reduce energy costs. Radiant barrier foil insulation systems BLOCK radiant heat energy instead of absorbing it like fiberglass insulation.
• Radiant barrier reflective foil insulation is unaffected by humidity and will continue to perform at a consistent level no matter how humid it may be. A radiant barrier foil insulation system is a layer of foil facing an airspace and is installed in the envelope of a building.

In order to fully understand how radiant barriers work and how they can benefit you, the following information has been comprised to provide a foundation for your new radiant barrier knowledge and understanding.

How Heat is Transferred: Heat is transferred from one source to another via three methods of transfer: conduction, convection, and radiation.

Conductive: The transfer of heat flowing through a substance (molecular motion) or to another touching substance. If you touch a pot on the stove, the heat is transferred from the pot to your hand via conductive heat transfer.
