Loft Conversion Insulation

Insulating a loft conversion can often be complicated, so make sure that insulation requirements are taken into account throughout the procedure of planning your loft conversion. As loft conversions are typically being converted into a habitable room, the modified space will have to fulfil building regulations for thermal efficiency, which specify a U-value for the amount of heat loss through an area. These values are set differently for walls, floors, windows and roofs, with flat roofs having to satisfy a different value to pitched ones. As with insulating many areas, it is often cost effective to insulate past the building regulations requirement as it’ll save on your energy bills. The most challenging part of insulating a loft conversion is usually the constrained space. Space saving insulation materials tend to be used in loft conversions as these will offer good insulation despite being very thin. When planning a loft conversion, ensure that there is plenty of space available for both the conversion itself and the mandatory insulation, as the insulation will have an impact on the ceiling height of the converted room. Dormer windows and rooflights will have to be insulated adequately. These areas require extra attention when planning insulation, particularly with flat roofed dormer windows, as these may well have to meet a different U-value than the surrounding pitched roof.
