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 vermiculite suitable for cavity wall insulation
There are some advantage,
Cavity wall insulation is an insulator. It is designed to fill the gap between the walls, providing thermal resistance to reduce heat loss in buildings.
it stops the air circulating
Because cavity wall insulation traps pocket of air thus reducing convection currents. Having just air will increase convection currents.
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.
A cavity wall consists of two separate layers of brick, with a gap (cavity) between them, providing better insulation and resistance to water penetration compared to a solid brick wall, which is made of a single continuous layer of brick. Cavity walls are more energy efficient and allow for easier installation of insulation materials.
Cavity wall insulation primarily works by reducing heat transfer through convection, as it traps pockets of air within the wall cavities. Some types of insulation may also use materials that reduce heat transfer through conduction and radiation.
The minimum recommended wall cavity size for insulation is typically around 2 inches to allow for proper installation of insulation material and to achieve the desired level of thermal performance. Insulating smaller wall cavities may still be possible with specialized insulation products, but it may be less efficient and effective.
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.
The layer that lines a cavity wall is called a cavity wall insulation. This material is typically made of foam boards, mineral wool, or other insulating materials, and it helps to improve the thermal efficiency of the wall by reducing heat loss.
