Sustainability…the Ibstock Way

Sustainability Roadmap 2025

Implementing our Sustainability Roadmap requires us all to work together. This needs ownership from the very top of the organisation as well as every employee feeling able to contribute. Joe Hudson, CEO, is the main sponsor for the Sustainability Roadmap at plc Board and Executive Leadership level. Sustainability will be a regular item on the plc Board agenda.

Our work in sustainability is underpinned by our Code of Business Conduct and Modern Slavery Statement. Applying the principles within our Code of Business Conduct ensures that all our business is conducted to the highest standards of integrity and business ethics.

Every level within the business will be expected to integrate our sustainability ambitions into their work. Much of this is already happening and during 2019 we will build on the consistency and measurement of the actions we take. With the new appointment Michael McGowan and Emily Landsborough as Sustainability Manager and Sustainability Advisor, respectively, we now have the knowledge and support in place to increase the pace of this integration. In 2019 we established a Sustainability Board and an internal Sustainability Working Group. These systems bring insight, inspiration and scrutiny into the business and enable us to respond to external challenges, as well as reviewing and monitoring progress against the Sustainability Roadmap to 2025.

Our Sustainability Roadmap is core to our business operations and values, we have identified ten targets under our four priority areas. View the our 2018 Sustainability Report for full details.Sustainability Roadmap 2025

Building long term relations

As a business we are committed to making a positive contribution to the communities around us and we are extremely proud of our partnership with Shelter. We will work with Shelter to raise awareness and vital funds to support people who are experiencing homelessness.


I passionately believe that in 21st Century Britain, everybody should have a warm and secure place to live. Together with Shelter – an organisation that shares our values and purpose – all of us can play our own part in making this a reality”

           Chief Executive Officer


Improving standards

There are a number of standards operated throughout the business which include environmental, energy and quality.

These provide a consistent set of procedures which are regularly reviewed and updated to identify ways in which they can be made more effective.

BREEAM, BRE Green Guide and BES 6001

BREEAM is an environmental assessment method by which new buildings are assessed against set criteria providing an overall score. Materials for these assessments are sourced through information obtained from BRE’s “Green Guide”. External wall specifications, when assessed in conjunction with this guide, are given a points rating from “A+” to “E”. All brick cladding specifications listed in the Green Guide achieve the highest (A+) rating. Being certified under BES 6001 demonstrates compliance with a recognised responsible sourcing scheme which is certified through a third party and which is supported by UKCG members and who give preference to procuring products demonstrating such compliance.

Eco Habitats…for Bats

In the UK there are 17 species of bats, all of which are protected by law. Our range of bat boxes helps to encourage safe habitats for these remarkable mammals, allowing them to live in harmony with people.

Eco Habitats for swifts

Swift Box

Swifts come to the UK for just months each summer from Central and Southern Africa. Despite legal protection their numbers are declining. Since Roman times they have been at home in traditional man-made buildings. However they find it increasingly difficult to find nest sites in modern or refurbished buildings due to the effective sealing of the eaves.

  • Designed with the needs of the swift in mind
  • Available in Smooth Blue, Smooth Cream and Smooth Red
  • Discrete nesting box for location near eaves
  • Ideal for new build and conservation work

Coolvault®…add thermal mass where it matters

For attractive ceilings with an environmental benefit

Natural clay has great thermal mass properties. It absorbs excess heat in hot conditions and releases it gradually as temperatures fall, helping to maintain a comfortable internal temperature.

  • Manufactured in the UK using over 90% recycled clay.
  • Adds thermal mass to even lightweight construction.
  • Suited for use with underfloor heating systems.
  • Can help reduce the amount of conventional heating or cooling that a building may require.
  • Available in natural cream or terracotta; the naturally C reflective surface requires no decoration.

Ecoterre® Earth Bricks…for internal non load bearing applications

A range of unfired clay bricks suitable for most internal non load-bearing applications. Unfired brickwork can be finished with a variety of materials including clay and lime plasters, clay boards, some paints and limewashes, making it an attractive addition to any building.

  • When incorporated into a building, it will help provide thermal mass and acoustic insulation, inhibit condensation and regulate the relative humidity of the atmosphere.
  • Excellent sustainability credentials including; low energy input, very low waste and high recyclability.
  • Available in two sizes with the option of a smooth finish.
  • Excellent bond properties with appropriate plaster or mortar.
  • Long life – potentially centuries if the correct care is given.
  • Allows customers to improve the energy efficiency of their home.

Handling & Storage

Only forks should be used to unload the pallets and the movement of unfired clay bricks should be kept to a minimum. Store in the dry on the original pallet and ventilate to avoid condensation. They should be stacked no more than two packs high.


It is recommended that moderately hydraulic lime mortar should be used to lay the bricks. Alternatively clay mortars are available.


Unfired clay brickwork can be finished with a variety of breathable materials including clay and lime plasters, clay boards, some paints and limewashes. Only highly vapour permeable paints should be used.


Unfired clay bricks will generally only require standard fixings for secondary works, such as plumbing, electrics and joinery. Ordinary masonry plugs and screws are suitable for most applications – a list of approved products is available below:
