loft

A loft is a building's upper storey or elevated area in a room directly under the roof (American usage), or just an attic: a storage space under the roof usually accessed by a ladder (primarily British usage). A loft apartment refers to large adaptable open space, often converted for residential use (a converted loft) from some other use, often light industrial. Adding to the confusion, some converted lofts include upper open loft areas.

    Should I insulate vent pipes in loft (from DHW cylinder and central heating)

    Hi I recently did some pipe insulating in my loft. The only two I didn't do were the vent pipes. Not sure if that is the right term for them? They are the pipes that feed water back into the top of the tanks when there is excess, presumably from steam, expansion, etc. The one going to the cold...

    What is this gunk filled container in the loft?

    We've just bought this house, and looking around the loft there is a large water container (clean) and a much smaller container next to it filled with mouldy looking gunk and a ball valve (?).

    Gas pipe under loft insulation.

    The copper gas pipe to my boiler in the loft runs between joists and sits on the plasterboard. I understand that it should not be covered by insulation. Why? Is it satisfactory to create a dome over the pipe with upside down guttering and then put fibreglass insulation over the top please?
