Room In Roof Insulation
A room in roof (loft room) or attic room is simply defined by the presence of a fixed staircase to access the room.
Many older properties that were originally built with room in roof were not insulated at the time. If insulation was installed, it is often inadequate by modern standards.
Loft conversions that were carried out more than 30 years ago are also likely to be poorly insulated, if at all, meaning that these rooms can be cold and difficult to heat.
