MULTI-CRITERIA COMPARISON OF INSULATION
MATERIALS
Daniel Savi,
MSc Environmental Sciences ETH
WHAT WE DID
Which insulation material is the best in terms
of environmental performance, application
suitability and cost?
We tried to answer this question based on
scientific data and objective assessment
models.

WHY MULTICRITERIA COMPARISON?
– Different Approach then „one score fits all“
– Comparison of up to 8 criteria in
radar/spider charts

Readers may choose
relevant criteria themselves
Communication of results is
more transparent than in an
aggregated way
+ -
Charts are more demanding
to read than a number
Different readers may not
come to the same
conclusions
HOW THE SPIDER CHARTS WORK

PRINCIPLES
Comparisons ...
– can only be made within the same
application,
– are based on the same insulation
performance, aka same R-Value for all
materials,
– include auxillary materials that change
with insulation thickness

SCIENTIFIC BACKGROUND
– LCA data used for assessment of
performance from cradle to gate and end-
of-use
– LCA data from newest available validated
and peer reviewed EPD, for few products
without EPDs from neutral LCA databases
– Assessment of use phase based on
producers documentation, safety
datasheets and REACH documents

ECOLOGICAL RULES OF THUMB
– Plastics insulations are favorable if high
pressure resistance or tensile strength is
needed
– Mineral insulation materials have good
environmental performance at low density,
which are possible if pressures are weak
– Renewable materials compare well, but
are not better than plastics or mineral
insulation materials
