Loft Conversion Insulation

Insulating a loft conversion can often be difficult, so ensure that insulation requirements are considered throughout the process of planning your loft conversion. As loft conversions are generally being converted into a usable room, the new space should fulfil building regulations for thermal efficiency, which state a U-value for the rate of heat loss through an area. These values are set differently for walls, floors, windows and roofs, with flat roofs needing to satisfy a different value to pitched ones. As with insulating many areas, it is often cost effective to insulate beyond the building regulations requirement as it’ll save on your energy bills. The trickiest element of insulating a loft conversion is typically the limited space. Space saving insulation materials are frequently used in loft conversions as these should provide good insulation despite being very thin. When planning a loft conversion, ensure that there is ample space available for both the conversion itself and the mandatory insulation, as the insulation will impact the ceiling height of the converted room. Dormer windows and rooflights need to be insulated adequately. These areas require extra attention when planning insulation, particularly with flat roofed dormer windows, as these may well have to fulfl a different U-value than the surrounding pitched roof.
