25 kg/m2 is a density of a toughened glass with 10 mm thick. If you want convert that measure into kN, then multiply by the factor "g" that is gravity (9.81 m/s2) and you get 25 x 9.81 = 245.25 kN/m2.
Toughened glass was first invented by a glassmaker who wanted to make a windscreen for a vehicle such as a car or a train so that it would break into lots of tiny fragments that would cause less injury to someone if they were thrown through it if the vehicle was involved in a collision. (If ordinary glass were used it would crack into large pieces which would badly cut that person.)

Toughened glass is transparent. It is translucent if frosted. To be opaque, it would need to be covered with something that won't let light through.
Any attempt to cut toughened glass will result in the glass shattering into thousands of pieces. The glass needs to be cut before the glass goes through the toughening process.
