DearSir/Madam,
In my bungalow loft there are 3 or4 joists running at right angles across the ceiling joists, one end of the joists are fixed in the outer wall of the bungalow and the other end is fixed in a centre wall. Then another joist end is fixed in the centre wall and the other end is fixed in the adjoining wall with next door.
What are these joists for? and what are they called?.
Yours Sincerely,
cubs.
