Concerns about materials used on flats
Following the recent statement that the materials used in the panels of the Grenfell Tower block in London were not fit for purpose, I am concerned about the materials used, as advised, to insulate our homes; in particular cavity wall insulation.
Cavity wall insulation works on the principle that if we fill the void between the inner and outer wall of a building with some heat retarding foam or beads, it will result in greater heat retention in that building.
However, my concern is not in the principle but if, as found in tower blocks across the United Kingdom, the materials used as an insulant are not also heat retardant, it could result in a fire in the cavity.
This could provide a perfect funnel for a fire to spread to other parts of the house, particularly the loft.
It follows, therefore, that some random sampling be done as a check on all insulating materials used past and present which would alleviate my concerns. John Stewart Wood Address supplied
