| The loft has 200mm (8inch) of glass fibre insulation. | | The loft hatch has draught seal but requires insulation. | | The recessed velux in the single story kitchen extension has 75mm of polyurethane sheet insulation on all sides of the recess. | | Because the kitchen spotlights generate a lot of heat they are not covered with insulation. They could also be a source of air entering the kitchen. | | |
