This is a 1970’s bungalow in Waterford, householders were finding this house difficult to heat. This was due to loose fibreglass insulation in cavity walls. Sisolutions extracted and disposed of this insulation, this work was carried out in one day. Refill of cavity walls with bonded bead insulation was carried out by Keating’s Insulation. Householder’s saw an immediate difference in heat and in heat retention.
