<strong>Esha</strong> is part of the largest membrane<br />
manufacturing group in the World with<br />
an ongoing commitment to producing<br />
increasingly environmentally friendly<br />
waterproofing membranes. The continual<br />
demand on Earth’s finite resources has driven<br />
the <strong>Esha</strong> Group to seek out even more diverse<br />
raw materials to increase the use of recycled<br />
post-use consumer waste. In pursuing this<br />
course over many years, <strong>Esha</strong> now lead the<br />
market and have contributed greatly to the<br />
reduction of wasteful landfill disposal and<br />
improvement in the sustainability of their<br />
membranes.<br />
The <strong>Esha</strong> philosophy is simply to provide the<br />
best solution at an affordable price whilst<br />
incorporating the best service with the most<br />
appropriate product thereby protecting the<br />
roof, protecting the client, and protecting the<br />
environment.<br />

<strong>Esha</strong> <strong>Universal</strong><br />
<strong>Future</strong> <strong>Proof</strong> <strong>Roofing</strong>
<strong>Esha</strong> <strong>Universal</strong> has changed<br />
the way we think about <strong>Roofing</strong><br />
ESHA UNIVERSAL is a new standard<br />
of roofing when it comes to quality<br />
and environmental care, it is a unique<br />
type of membrane more flexible and<br />
stronger than conventional roofing<br />
with greater stability and durability.<br />
<strong>Universal</strong> owes its outstanding<br />
performance to its extraordinary<br />
composition and homogenic<br />
character: a POCB compound<br />
reinforced with polyester and<br />
stabilised with glass. To manufacture<br />
this unique product a new<br />
production method has been<br />
developed and patented.<br />
ESHA UNIVERSAL has been created<br />
in response to the growing demand<br />
for products that contribute to<br />
reduced energy consumption and<br />
damage to the environment. It can<br />
be easily installed in various one-layer<br />
applications and most importantly<br />
ESHA UNIVERSAL is totally recyclable.<br />
ESHA UNIVERSAL has been subject<br />
to Life Cycle analysis involving rigid<br />
test in the total life cycle of the<br />
product and its environmental<br />
impact. The research proved that<br />
by selecting <strong>Universal</strong>, impact on<br />
the environment is greatly reduced.<br />
The European Agrément certificate<br />
K1190 attests to the performance<br />
and quality of <strong>Esha</strong> <strong>Universal</strong> and<br />
the suitability of the membrane in<br />
a given roofing system.<br />
Of course even with a unique roofing<br />
system as <strong>Universal</strong>, <strong>Esha</strong> still<br />
guarantee the product against failure<br />
and consequential damage. Where<br />
required an All In Guarantee is<br />
available which also protects against<br />
failure of the contractor or supplier<br />
and even the client’s surveyor<br />
costs and removal of site debris<br />
are included.<br />
Everyone agrees CO2 reduction is a key<br />
to sustainability for the planet, <strong>Esha</strong><br />
already achieve this with their bitumen<br />
balance programme. Independent<br />
research verifies that recycled content<br />
incorporated in 1m2 of <strong>Esha</strong> roof<br />
membrane equates to a reduction<br />
in CO2 generated, equivalent to that<br />
emitted whilst driving 1km in a car.<br />
The current process is optimised in<br />
phase 1 at 40% recycled content.<br />

for Applied Science.)<br />
The European Life programme has<br />
co-funded many projects developing<br />
solutions to environmental issues.<br />
<strong>Esha</strong>’s development of recycling<br />
facilities for waste roofing<br />
membranes has earned a grant of<br />
11.25 million to further improve and<br />
expand this facility to demonstrate<br />
technically and economically a<br />
feasible alternative to incineration<br />
and landfill. <strong>Esha</strong> expects to move<br />
current volumes of 12,000 tonnes<br />
recycling to 50,000 tonnes in year<br />
three of the programme.<br />
<strong>Esha</strong> built it’s first recycling plant in<br />
1994. In year 07 capacity will reach<br />
12,000 tons per year enabling many<br />
products to contain upwards of 40%<br />
recycled content. To protect the future<br />
<strong>Esha</strong> <strong>Universal</strong> is designed to be<br />
totally recyclable which means no<br />
harmful chemicals or heavy metals are<br />
used in the product. This means that<br />
virtually every ton of <strong>Universal</strong><br />
removed from a roof in 30 or 40 years<br />
time will be reusable. This completes<br />
the virtuous circle of bitumen balance<br />
by recovering earth’s resources and<br />
reusing them time and time again.<br />
