Airtight insulation is the key to meeting the new, tougher Part L regulations on CO₂ emissions from new buildings. The Goldthorpe development can be seen as proof of WARMCEL’s airtight properties –low air permeability combined with complete void fill during installation.

Client Chevin Housing Association appointed HRS Services to undertake Envelope Airtightness Testing on the finished build.

At 50Pa, the testing returned an air leakage result of just 1.5m³/hr/m²; considerably better than the target of 8m³/hr/m²) required by the new Part L regulations.

The project achieved CfSH Level 3 without any requirement for additional (and potentially costly and maintenance-heavy) technologies such as solar panels or ground source heat pumps.

Environmentally-friendly WARMCEL insulation helped Rogiet School, Monmouthshire, become the highest BREEAM-rated school in the UK.

The project won the BREEAM Schools Award 2010, with an Excellent rating of 78.18% (the highest ever for a UK school),

as well as both Constructing Excellence In Wales and National awards for Integration & Collaborative Working.

As well as sequestering carbon, the use of airtight WARMCEL insulation also ensures a low energy footprint for the life of the building.

Excel Industries’ WARMCEL-insulated TRADIS system has been installed as part of the £4.6m construction of the Department of Agriculture Fisheries & Forestry (DAFF)'s new Isle of Man headquarters.

Timber frame manufacturer Eden Frame constructed the TRADIS panels and installed the WARMCEL 500 insulation - which has

better than zero carbon properties and is manufactured from 100% recycled newspaper - offsite, prior to transport. This system leads to incredibly fast construction turnaround and guaranteed quality control as well as the inherent environmental benefits of using timber framing and WARMCEL insulation.
