Packs of laminate flooring would i need

you need 14 square metres so depending on the square metres in a pack standard pack 2.25 so 7 packs 10% wastage thanks

I would say 8 to 9 pack. Depends on the way it's getting layed How in a pk as some are 6 to 8 I would use the green pads for the underlay. Just incase theres any bumps

Based on the size given. And going off a pack size of 2.25 you will need just under 6 packs but you should allow for a cuts so 7 packs would be enough. In regards to the underlay i only use Timber mate excel it's a heavy dense product that does the proper job

Cheaper would be 6packs depending on how the customer wanted the laminate flooring fitted so he his right but I'd give the two options
