Assuming your neighbour's house is not already insulated, the Technician will insert a cavity barrier at the party wall line. This is usually a length of bristle brush. Of course, if the neighbour's house were to be insulated at the same time, the cavity barrier would not be needed.
Are all the systems of insulation the same?
There are several different types of insulation:
- Bonded bead (white polystyrene beads)
- Glass wool (Yellow or white in colour)
- Rock wool (Grey/brown in colour)
- Urea formaldehyde foam (white foam)
Note: both glass wool and rock wool are known as 'mineral wool'.
Energycare's systems of CWI have been tested, assessed and approved by the British Board of Agreement or the British Standards Institution. All are suitable for their purpose. Except for Urea Formaldehyde foam, the systems can be used in all parts of the UK. All systems have a similar insulation value.
