Loft Conversion Insulation

Insulating a loft conversion can often be complicated, so make sure that insulation requirements are taken into consideration throughout the process of planning your loft conversion. As loft conversions are commonly being changed into a habitable room, the new space must satisfy 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 being required to satisfy a different value to pitched ones. Just like insulating many areas, it is typically cost effective to insulate past the building regulations requirement as it’ll save on your energy bills. The hardest part of insulating a loft conversion is generally the limited space. Space saving insulation materials tend to be used in loft conversions as these will provide good insulation despite being very thin. When planning a loft conversion, make sure that there is enough space designed for both the conversion itself and the required insulation, as the insulation will lower the ceiling height of the converted room. Dormer windows and rooflights should be insulated sufficiently. These areas require extra care when planning insulation, especially with flat roofed dormer windows, as these may well have to comply with a different U-value than the surrounding pitched roof.
