Why Sheet goods?
Titanium Series esd flooring is available in sheet goods (or optional tiles) for a very good reason. Let's look at a 150' x 60' area. A typical 1' x 1' ESD tile will have over 18,000 linear feet (nearly 4 miles of seams)! Take a look at this
3M esd tile floor. Bad tiles? Poor install? Not at all. Unfortunately tiles don't always fit perfectly and the installer must adjust (leave small spaces between the tiles) as the installation progresses (some tiles even shrink over a period of time).
And/or the substrate isn't flat leaving an uneven profile (slight highs and lows) to the finished install. Minute spaces between the tiles and/or deviations in the flatness, a perfect environment for contaminant and dirt entrapment. On a standard tile floor these deviations typically present little problem, they are often filled in with floor wax. Esd floor finish shouldn't be a necessity for a quality esd floor. It raises the insulative properties, can wreak havoc in a clean room (from powdering), is expensive and can be a maintenance application nightmare!
Titanium sheet goods, same area? less than 2,000 linear feet of seams and these seams are heat welded for the ultimate in cleanliness and ease of maintenance.
