Following a major success in Central Europe, Bauwer Group introduced a cost efficient, sustainable and environmentally friendly insulated render and plaster in the UK. Thanks to the volcanic glass called Perlite and Vermiculite, currently it is the most cost effective solution to insulate, level and dehumidify the walls while improving comfort and sound absorption properties of a building.
Thanks to its mineral basis, lime and cement, Bauwer render is very similar to the traditional renders and plasters, and this makes it ideal for use in the buildings improvement, internally as well as externally.
The know how behind the Bauwer’s insulating render and plaster is a naturally occurring minerals called Perlite and Vermiculite. Rapidly heating perlite ore to temperatures of about 900°C softens the volcanic glass causing entrapped water molecules in the rock to turn to steam and expand the particles like popcorn. The expanded particles that result are actually clusters of minute, lightweight, insulating, glass bubbles. Sophisticated manufacturing techniques allow the expansion and collection of individual perlite bubbles, which are used as -fillers within the Bauwer Insulation. These minute pores make Bauwer an excellent insulation material for use in the variety of different application which two to three times more cost efficient vs traditional render or plaster due to lightweight nature of Bauwer.
Further advantage of Bauwer insulation is that the wall is being permeable to water vapor. Bauwer Insulation is significantly more breathable than conventional plasters, and hence it is able to withstand fluctuations in internal and external humidity which helps preventing any damp or mould issues.
Perlite and vermiculite do not emit any odours and are resistant to chemical and biological effects of environment. Bauwer insulation contains no organics, chemically inert, biologically stable, non-toxic, harmless and safe.
Moreover, perlite and vermiculite minerals are used in water filtration and horticulture industries as well, due to its lightweight structure and non-toxic, inert nature.
The first building was plastered by Bauwer was in central London, Carlton Hill. The cost saving vs traditional plaster was about 40% vs original cost estimate.

I’ve used the Bauwer Lite insulating render on a job in Putney, South London. We applied it to 35/40mm with no apparent sign of slumping. Very impressed with the product, would use again.
