footprint. One sterling innovation is the use of recycled
plastic bottles for insulation.
Every year, millions of plastic PET bottles are thrown
away into rubbish dumps and landfill sites. In addressing
this major environmental problem, plastic bottles are
converted into thermal insulation to be used to insulate
buildings. This type of material complements the
architectural and construction practice of green building
by increasing the energy efficiency of buildings and
reducing the impact buildings have on human health
and the environment.
According to ISOTHERM, thermal insulation manufacturer,
such thermal insulation in ceilings, on geysers and water
pipes can reduce energy consumption and cost, while
regulating indoor temperatures. In accordance with the
global trend to regulate the design and construction of
buildings for maximum energy efficiency, South Africa has
recently updated the National Building Regulation, namely
SANS 10400. The new regulation stipulates that all new
buildings or additions and alterations to existing buildings
must comply with energy-efficient standards, including the
insulation of floors, walls, windows, ceilings and roofs.
DEEMED-TO-SATISFY THERMAL
INSULATION REQUIREMENTS:
• Non-masonry walls shall achieve a minimum total
R-value of 2.2m²K/W in climatic zones 1 and 6, and in

2.7m²K/W in climatic zones 3 and 5.
