Multifoil Loft Insulation Installation in Felixstowe Judith Hammond in IP11, Felixstowe, was experiencing extreme temperatures in her end-of-terrace home—freezing in winter and boiling in summer. After discussing our recommendation of Multifoil insulation, she chose this as the best solution. We installed Multifoil insulation to the roof rafters, ensuring all joins were overlapped and taped for airtightness. The exposed end gable was also insulated with Multifoil to maximise heat retention and comfort year-round.
