What is different about insulating an older home's loft?

We work from crawl boards spanning several joists so the ceilings are not loaded, check for loose plaster keys before anything is laid, and usually recommend vapour-open insulation such as sheep's wool or wood fibre. Unfelted slate roofs are naturally well ventilated, but they let in wind-driven rain and snow, which the insulation has to cope with. More about loft insulation for an older house.

It can if people kneel between joists or if the ceiling is already weak. We work from boards and check the ceiling first.
