Loft Conversion Insulation

Insulating a loft conversion can often be tricky, so be sure that insulation requirements are taken into account throughout the process of planning your loft conversion. As loft conversions are commonly being changed into a habitable room, the modified space must meet building regulations for thermal efficiency, which establish 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. 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 trickiest element of insulating a loft conversion is generally the constrained space. Space saving insulation methods are often found 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 lower the ceiling height of the converted room. Dormer windows and rooflights must be insulated adequately. These areas require extra care when planning insulation, particularly with flat roofed dormer windows, as these could have to conform to a different U-value than the surrounding pitched roof.
