    Why use Knauf?

    Knauf insulation materials have great thermal conductivity, sounds absorption and reaction to fire classifications. Insulation helps to create a dry, comfortable indoor living and working environment in residentials and commercial buildings. It also helps to have a positive impact on a person’s health by preventing air leaks, uncontrolled condensation and possible mould spores, mildew or microbial organic compounds. A well-insulated, airtight building envelope also contributes to the health of a building, particularly if combined with efficient installation solutions and a controlled ventilation system. Good quality insulation can help save energy bills on both residential and commercial buildings by keeping the temperature regulated.
