Ecological Building Systems
eco-electricity, the extremely durable
insulation is designed to last for the
lifetime of the building and is then
totally recyclable, completing the circle
of sustainability that starts with a seed
in the ground.
Unlike conventional PIR board
insulation, thermo jute is a flexible,
fibrous material that can be installed
quickly and easily, making it an ideal
solution for the hands-on self-builder.
Free from harmful ingredients, it will
not cause any skin irritation, itching
or respiratory discomfort during
installation, so no special protective
wear is required.
The material is suitable for
installation between rafters and
ceiling joists, between floor joists and
in partition and stud wall build-ups,
enabling it to be designed into different
areas of the construction. This flexibility
also maximises compatibility with
a broad spectrum of design styles,
including conversion and refurbishment
projects, as well as newbuilds.
During the upcycling process from
gunny bag to insulation, thermo
Jute loses none of the natural
properties that makes jute such
a useful and versatile material.
No mould, mildew or fungus can
grow on thermo Jute, earning
the insulation a top rating of
‘0’ (according to EN ISO 846).
Protein and starch-free, it is resistant to
any insect infestation, helping to protect
the fabric of the building and the home
environment throughout the lifetime of
the finished project.
Functionality without compromise
Perhaps the most compelling reasons
for installing natural jute insulation are
the performance benefits this pricecompetitive
solution can provide. With
a lambda value of just 0.038, thermo jute
offers very low thermal conductivity,
providing an excellent barrier to cold
air during the winter months. The soft,
flexible nature of the insulation material
also ensures it can be packed tightly
into voids, enhancing airtightness and
therefore maximising the benefits of its
When selecting an insulation solution
for a self-build project, it’s also important
to consider the product’s impact on
indoor comfort during the summer
months. Thermo jute’s excellent thermal
storage capability significantly reduces
the possibility of a home over-heating during
warmer weather. Meanwhile, its hygroscopic
qualities also help to regulate humidity.
Thermo jute’s high-density structure even
acts as an acoustic buffer, helping to keep a
property quieter, as well as supporting a more
comfortable, ambient indoor climate.
Having committed to environmental principles
when starting a self-build project, it can be hard
to reconcile those aims with the need to create a
durable, energy-efficient and comfortable home;
but it’s not impossible.
The use of natural jute insulation enables selfbuilders
to actively protect the environment by
using a material that is produced from renewable
sources using green energy, in the knowledge
that it can ultimately be recycled again. When
all of those environmental benefits are balanced
by a price-competitive solution that offers
excellent thermal performance for a home that’s
warmer in winter and cooler in summer with
no risk of mould or insect infestation, it’s a true
