Tad OT but one of our customers has, this summer, moved into the largish two story office building where they occupy the upper floor.
Already the heating bill, electricity!!, yes stupid mistake I know, is costing them the earth.
The have a suspended tile ceiling like most offices and the roof seems to be of some sort of composite board and the space betwixt the roof and suspended ceiling is quite hot.
I can only suppose that its all leaking through the ceiling and there being no isolation....
However I've never seen insulation in offices like this . Is it the done thing.. Or seemingly not?...
cheers
