Is cavity wall insulation a conductor or insulator?
a wall is a conductor
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
What are the advantages of cavity wall insulation?
There are some advantage,
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 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.
