What are the advantages of cavity wall insulation?
There are some advantage,
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.
Are vermiculite insulation granuals waterproof for external wall cavities?
is vermiculite suitable for cavity wall insulation
Is cavity wall insulation a conductor or insulator?
a wall is a conductor
What is the Minimum wall cavity size for insulation?
100 mm
How does cavity wall insulation work?
it stops the air circulating
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 is the basic function of insulation?
Heat insulation reduces the rate of heat flow. Sound insulation reduces the amplitude of the sound energy transmitted through a cavity.
What type of heat loss is reduced by cavity wall insulation?
convection
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.
