What we insulate in a room-in-roof
Sloping ceilings: insulated lining boards reduce radiant losses directly above you.
Dormer cheeks: thin build-ups keep tight spaces warm without eating the room.
Dwarf/pony walls: common cold-spots behind storage — we insulate & seal.
Flat ceiling to apex: controls stratification and summer heat ingress.
