Loft Conversion Insulation

Insulating a loft conversion can often be tricky, so be sure that insulation requirements are considered throughout the process of planning your loft conversion. As loft conversions are typically being changed into a habitable room, the modified space will need to meet building regulations for thermal efficiency, which state a U-value for the speed 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 normally cost effective to insulate past the building regulations requirement as it’ll save on your energy bills. The most difficult part of insulating a loft conversion is typically the constrained space. Space saving insulation methods tend to be used in loft conversions as these will provide good insulation despite being very thin. When planning a loft conversion, make certain that there is plenty of space available for both the conversion itself and the specified insulation, as the insulation will have an effect on the ceiling height of the converted room. Dormer windows and rooflights will need to be insulated sufficiently. These areas require extra care when planning insulation, particularly with flat roofed dormer windows, as these may have to fulfl a different U-value than the surrounding pitched roof.
