I went out like good little boy the other day to take advantage of the B&Q 3 rolls for £3 deal they had on the loft insulation. i planned to extend the joist height to allow me to board on top of the insulation to store cases etc.
The problem is: I live in an 1890's mid terrace, and the joists are not 4x2", but 3x1.5". I've been told by the local timber merchant that these joists are too puny to withstand the extra weight and i'd need to fit vertical supports from the A frame timbers.
Is this true?
If it is, what's the easiest way of achieving my goal?
I'm half decent with a saw and drill, but not too hot on the jargon, so please keep your replies in laymans terms!!!
