Howie Forest Products Sawn Regularised Strength Graded C16 Construction Timber (L)3600 x (W)175 x (T)47mm
Its a lot of wood for your money :)
Particularly for those who recently ordered extra loft insulation and need to raise the joist height so they can put some flooring down in the loft.
Normal price is £6:56 but its 15% off this weekend. Best I could get for something similar from timber merchants was £8.45.
Just a note that no stock was held in any of the stores in my area, apparently it is not normally "ranged" they have to put in a special order, delivery quote is a couple of weeks but timber man said it should be fairly quick.
