Cavity Wall Insulation is one of the best ways to save electricity around the home to keep your home warmer in the cold months. A great way of doing this is to invest in insulation such as cavity wall. The carbon and eventual cost savings of insulating our homes is terrific and typical savings for cavity wall insulation for example is:
* Typical cost: £250
* Typical carbon: 610kg
* Typical payback: 2 years
What if you have an older 'solid wall' home. These can indeed be difficult and expensive to insulate, however there are methods other than external cladding.
Solid wall insulation can be performed in several ways, with the best being involving adding an extra layer to the inside face of exterior walls - either boards within a narrow wooden frame or a clever flexible material called Sempatap.
Either way it is expensive, and the return on investment is longer, but the carbon savings are great.
* Typical cost: £5,500 - £8,500 (internal) £10,500 - £14,500 (external)
* Typical carbon: 2000kg
* Typical payback: Varies, but normally at least 10 years

Is cavity wall insulation a conductor or insulator?
a wall is a conductor
Are vermiculite insulation granuals waterproof for external wall cavities?
is vermiculite suitable for cavity wall insulation
What are the advantages of cavity wall insulation?
There are some advantage,
How does cavity wall insulation work?
it stops the air circulating
What is the Minimum wall cavity size for insulation?
100 mm
Why cavity wall insulation is better than air the cavity between the walls of a house?
Because cavity wall insulation traps pocket of air thus reducing convection currents. Having just air will increase convection currents.
Why is cavity wall insulation better than air in the cavity between the walls of a house?
Because cavity wall insulation traps pocket of air thus reducing convection currents. Having just air will increase convection currents.
What type of heat loss is reduced by cavity wall insulation?
convection
How does cavity wall insulation reduce energy transfer?
Cavity wall insulation is the addition of an insulating material between two layers of wall on the outside of a building. It reduces energy transfer by preventing heat (from the inside or the outside) from travelling through the wall to surrounding air.
What is cavity wall?
Cavity wall insulation is used to reduce heat loss through a cavity wall by filling the air space with a porous material. By doing this the porous material absorbs the escaping water and air.
How cavity wall insulation helps to reduce heat loss?
A major part of the heat transfer through a cavity wall lacking insulation is convection - and to a lesser degree radiation. When insulation is placed in the cavity between the walls it significantly reduces both convection (air doesn't move well through insulation like it does in empty space) and radition (the walls can't "see" each other through the insulation). For the insulation to be effective, the thermal conductivity of the material must be low enough that conduction through the insulation is much less than was present with convection.
How does loft insulation stop conduction and convection?
Loft insulation stops conduction and convection as the insulation which is inserted into the wall cavity prevents the particles of heat energy from traveling through the wall cavity, this stops conduction from taking place. Loft insulation also prevents convection as the cavity insulation stops the air particles from moving, therefore they cannot transfer heat and convection cannot take place.
