Working towards a sustainable future

Operating within the construction industry and as a leading investor within the insulation sector, Xtratherm remains at the forefront of energy efficiency and sustainable construction.

The Sustainable Solution

Specifying Xtratherm is a real commitment to minimising energy
consumption, harmful CO2 emissions and their impact on the
environment. Using our products is one of the most effective ways
to reduce energy consumption – in fact, after just eight months the
energy they save far outweighs the energy used in their production. In
addition, our manufacturing facilities operate to an ISO 14001 certified
Environmental Management System.

The BRE Green Guide

The 2008 Green Guide to Specification produced by the BRE gives
Xtratherm Insulation products a rating of A or A+. Green Guide ratings
are used to gain credits in BREEAM (BRE Environmental Assessment
Method) for non-residential buildings, and under ‘Mat 4 – Insulation’
the first credit requires the building to have an Insulation Index of
2 or greater – only achievable if the weighted average rating of the
insulation is A or A+. This shows that all our products have been made
with materials that have been responsibly sourced. The standard
sets out organisational governance, supply chain management
and environmental and social aspects that are verified and ensure
responsible sourcing of materials.

Responsible Sourcing

Xtratherm has BES 6001 certification for responsible sourcing.
The second BREEAM credit under that category is based on
responsibly-sourced materials – at least 80% of the total insulation used
in roofs, walls, ground floors and services must meet any of tier levels 1
to 6 in the BREEAM table of certification schemes. Our Environmental
Management System is certified under EN ISO 14001, and our raw
materials come from companies with similarly-certified EMS (copies
of all certificates are available for BREEAM assessments). This level of
responsible sourcing meets tier level 6 in the BREEAM table.

Global Warming and Ozone Depletion

All Xtratherm Insulation products use CFC-and HCFC-free materials,
and are manufactured using a blowing agent with a low GWP
and zero ODP.

Our products are designed to meet the most stringent environmental certifications.
