Loft Conversion Insulation

Insulating a loft conversion can often be complicated, so ensure that insulation requirements are considered throughout the process of planning your loft conversion. As loft conversions are generally being changed into a usable room, the modified space will have to meet building regulations for thermal efficiency, which define 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 required to satisfy a different value to pitched ones. As with insulating many areas, it is generally cost effective to insulate beyond the building regulations requirement as it’ll help save on your energy bills. The most challenging part of insulating a loft conversion is usually the restricted space. Space saving insulation materials are in many cases utilised in loft conversions as these should offer good insulation despite being very thin. When planning a loft conversion, be sure that there is adequate 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 must be insulated adequately. These areas require extra attention when planning insulation, particularly with flat roofed dormer windows, as these may well have to conform to a different U-value than the surrounding pitched roof.
