I'm planning to part board my loft (an area about 2.5m by 2.5m) for storage and it seems like the norm is to use tongue and groove chipboard like this. However I have some concerns about it;
- The packs come in lengths of 122cm and the rows must be offset, which means a lot of sawing, which means buying a small circular saw.
- The offsets mean some half boards will only span 2 joists, spreading the weight less.
- I've seen references that the recommended max loading in lofts is 25kg/SqM. The chipboard is very heavy (13kg/SqM) which means I can store less stuff.
I'd much rather use some whitewood timber like this. It comes in lengths of 240cm so each plank is the ideal size to span 5 * 60cm joists, which is the area I want to board. I realise its more expensive but due to the relatively small area the extra cost is acceptable. My question is whether this timber is suitable for flooring? Also, it is not tongue & groove, is this relevant?
