What Is Insulation, Why Do We Have It And How Does It Work? A small science lesson about insulation: Heat moves from warmer areas to colder areas. This is the single basic principle on which the idea of insulation is based. On hot days heat tries to get inside your house and on cold days the heat tries to escape. Insulation seeks to minimise this ebb and flow of temperature by slowing the process.

Unfortunately no matter how good your home insulation is, any building always needs a constant supply from a heat generating source to maintain a steady temperature. Of course however, if you have good insulation then you will need much less heat and thus a lot less energy to achieve the same effect. Most of us learned in GCSE science about conduction convection and radiation.

Here is a brief summary of each to refresh every ones memory. Conduction This is the process that heat flows through or along one material and into another. This is done through molecular transportation. To do this, the materials must be in contact with each other. This conduction happens with all things of liquid, solid or gas substances but that rate at which it happens greatly varies depending on the substance and its state i.e. if it is a good conductor or a bad conductor. Good metal conductors include gold, silver and copper down to the worst conductors like wood and THERMAL INSULATING MATERIALS. Gases and liquids are also bad conductors BUT are prone to the other, convection. Convection The requirement for solids to lose or gain heat by this process it must be in contact with the liquid. Convection happens when a change in temperature happens in parts of the fluid thus causing the liquids density to alter. This is called ‘natural convection’. If the fluid in instead displaced and accelerated by wind or artificial factors then it is called ‘forced convection’. In forced convection the process of convection can be increased substantially. Radiation This is how heat is emitted from a body and transmitted across a space as energy. This kind of radiation is similar to radio and light waves. It does not even need air in between for it to happen, and works just as well in a vacuum. Every solid body emits energy but the rate of emission all depends on three different things. Distance between surfaces The emissive of the surfaces (shiny and light/matt and dark) Temperature differences between receiving and radiating surfaces House insulation The application of thermal insulation does not have the effect of generating heat in your house. It is still always the rule that you will have to supply heat from an inside source. There may be a rise in temperature inside the building after the installation of insulation but that will be down to the better performance and energy saving properties of better house insulation.

There are many areas where you can experience significant energy savings when you are building a green home. 

By working with an architect in the early design stages, many of these areas can be addressed in the design of your energy efficient home, helping you to save money in the future and enjoy a healthier home:

1)Footprint:Reduce the size of your home.Your home design

should be limited to only as much space as your family needs.This will keep your energy usage to a minimum right from the start. 2) Windows:Windows are a break in the thermal insulating barrier of your home.The higher quality window you choose the better performance the entire home will achieve. 3)Insulation:Even if you do nothing else, by choosing a superior building envelope for your home like structural insulated panels (SIPs panels) and/or an insulated concrete form foundation system (ICF), you will enjoy huge savings in heating and cooling your home (up to 50%-60% over a home without SIPs). 4) Passive solar design:By incorporating sunlight for lighting and heat and natural ventilation into the basic home design, you can reduce the size of mechanical systems and lighting in the home. 5) Heating system:Consider a renewable energy system to heat and cool the space and tap water in your home (solar, wind, geothermal). 6) Ventilation:Incorporate an air-to-air exchanger, or heat recovery ventilator (HRV) system into your home.

This will replace stale air with fresh outdoor air while maintaining the temperature inside the home and conserving energy. There are many other areas of the home that can be addressed to increase energy efficiency and save money over the life of your home. In the beginning stages of the home design, your green architect will discuss your opportunities to save money while providing a healthy environment for your family.

Using insulated plasterboard after installing chemical damp proof … Hi, I know there have been previous posts about insulated plasterboard. My question is this: I have a terraced house approx 120-130 years old with solid brick walls, no cavity.

Heat transfer in steel buildings occurs in three ways. They are conduction, convection and radiation. These problems can be regulated using proper insulation.

Steel building insulation slows down the movement of heat. Insulation can regulate the temperature of these buildings.

Steel building insulation also helps to diminish sound by sound absorption. The type and amount of insulation

depends on the location of steel buildings. Steel building insulation provides energy savings, noise control and condensation control. There are different methods for steel building insulation.

The most widely used method for insulation is fiberglass insulation. Long strand fiberglass blankets are used for steel building insulation. Fiberglass is laminated on one side to a vapor barrier facing. Fiberglass insulation depends on the thickness of the blanket and the type of facing material. The quality of the fiberglass blanket is related to its thickness. Heat flow slows down with the increasing thickness of insulation. Facing material is important in fiberglass insulation method. The main function of the facing material is to act as a vapor barrier. Different facing materials vary in their workability, permeability and durability. The workability of a facing material is related to the temperature conditions required for installation. Permeability of a facing is connected to the rate of water vapor. Durability refers to the physical quality of the facing material.

The most commonly used facing material is polypropylene. The relative effectiveness of an insulator is determined by R value. R value is used to measure the total thermal transmittance of a material.

Reflective insulation is another method for steel building insulation. Reflective insulation is used to maintain the natural temperature. Heat transfer can be regulated using reflective insulation. Reflective insulation is composed of two outer layers of aluminum foil and an inner layer of inert material. Polyethylene or plastic can be used as the inner layer. Fiberglass inner layer gives more insulation power. Reflective insulation is not affected by humidity. It requires no special handling or clothing and is effective in both warm and cold weather.

Spray on insulation is a method for steel building insulation. It can be used for fire protection, moisture and thermal insulation. Spray on insulation consists of a mineral fibre and polyvinyl alcohol. The surface of steel is sprayed using a machine. Polyurethane spry foam can be used for steel building insulation.
