Knauf Plasterboard

Brothers Karl and Alfons Knauf founded the company in 1932 after securing the right to mine gypsum deposits in the Schengen community in Germany. A year later, Knauf built its first gypsum factory in Perl, southwest Germany. Today the Knauf Group is led by former Bosch Rexroth President Manfred Grundke in the position of Managing Partner, alongside Alexander Knauf who is also Managing Partner.

Here at Online Insulation we offer a range of Knauf products, including Fire Resistant Plasterboard, Moisture Resistant Plasterboard and Soundshield Plus Plasterboard. We at Online Insulation are in a fortunate position to be able to offer this type of plasterboard for less than other suppliers as we buy in bulk and pass our savings on to our customers.
