Hanson guide to achieving Code for Sustainable Homes

Hanson has launched a new guide to highlight how its Thermalite® block range can help developers achieve all levels of the Code for Sustainable Homes.

The Code for Sustainable Homes (the Code), a Government initiative introduced in 2007 and updated in October 2010, sets out to improve the sustainability of new housing.

Homes are assessed using nine key criteria and awarded an overall score ranging from Level 1 (basic) to Level 6 (exemplary). Level 3 is now required for all new housing, with social housing having to be built to Code Level 4.  By 2016 all new homes will have to achieve Code Level 6.

Hanson’s new guide shows how its Thermalite® range can assist in securing valuable credits across the energy, materials and health and well-being categories of the Code.

Thermalite® also helps secure additional credits because all products are certified as ‘very good’ under BES 6001 Responsible Sourcing of Materials achieving the top tier level (tier level 1), giving the maximum credits available under Mat 2.

Thermalite’s independent life cycle assessment means that it achieves better than the generic aircrete rating on a number of Robust Detail separating wall Green Guide specifications.

Using Thermalite on external walls can give the highest Green Guide rating of A+ and the maximum of three Code Mat 1 credits. 

Chris Hornby, head of product services, said: “It is vital that the Code is interpreted into practical and easy to understand product guides allowing architects, specifiers and builders to make the most informed choice when it comes to selecting construction materials.

“With minimum standards that have to be met at every level of the Code, our guide not only sets out how the credits can be gained, providing detailed information on all of the sub-sections of the Code that apply to Thermalite®, but also provides useful tips and practical examples.”

Thermalite® blocks from Hanson are made from up to 80% recycled materials and their light weight means that they can be laid more quickly, leading to significant productivity gains. There's also no need for special tools or fixings, and the blocks provide an excellent background for internal or external finishes.

In addition, by building using traditional materials in a ‘fabric first’ approach, developers can achieve cost-effective solutions to reaching Code Level 3 without the need for renewables.

The guide ‘Achieving the Code with Thermalite’ is available to download from Hanson’s website or you can request a hard copy by emailing thermalitesales@hanson.com or by calling 08705 626500.
