Are vermiculite insulation granuals waterproof for external wall cavities?
is vermiculite suitable for cavity wall insulation
What are cavity walls?
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 all of the air and water and stops it from escaping the house or building.
What are the disadvantages of cavity wall insulation?
1st answer is that scaffholdings are going to have to be installed and taken off which is going to take some time
How do you stop heat loss through walls when you can not have cavity wall insulation?
keep curtains closed have a been bag dog on the outside of the door at the bottom to minimise drafts, heat loss.
How do you prevent heat loss in the home?
You should do all these things. * Have loft insulation fitted * Have cavity wall insulation fitted * Draught excluder placed by your doors * Carpet your house all the way round * Have double glazing fitted. You will save lots of valuable pounds.
Is cavity wall insulation a conductor or insulator?
a wall is a conductor

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?

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 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.
What keeps your house insulated?
loft insulation, draught proofing cavity wall insulation thick curtains thick carpets double glazing
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.
