I had decided to go with block board for the loft door because that is what the current (too small) door is made of and the blocks are good to screw into end on.
However block board seems about as common as rocking horse droppings - I understand that it is hard/impossible to get some that is FSC certified so the normal merchants are prevented from supplying by their own rules.
One alternative is to make a door out of insulation clad in timber and MDF but I am time and resource limited.
The big problem with other composite boards is the lack of strength if you screw into the end.
So I was wondering if there were any inserts - a bit like wall plugs perhaps - which could be sunk into the end of the board to provide a stronger fixing.
Any other strengthening options?
Gate style hinges bolted through could work, but might be a little less attractive to look at.
Cheers
