McVeigh Insulations enables Document L compliance

McVeigh Insulations offers an innovative approach to construction techniques which enables a 25 per cent reduction in a building's carbon emissions to be achieved.

The company's large format Structural Insulated Panel (SIP) technology now yields a U-value as low as 0.1W/m2K, and airtightness of less than 5m3/hr/m2 @ 50Pa, some 50 per cent better than the maximum criteria laid down under the new Approved Document L which comes into force in October.

The panels, up to 7x3.8m, also provide greater structural integrity to the completed building, minimising the number of components to be positioned on site.

The reduction in abutments, joints and fixing penetrations further reduces risk of air leakage, and thermal bridging issues, simplifying construction to gain compliance.

The 100 per cent 'end of life recyclable' panels also attain an A rating under the BRE Green Guide to Specification.

The performance figures are proven in reality: McVeigh large format SIPS were used to help construct the new Hope Academy in Liverpool which has achieved an 'Outstanding' rating under BREEAM and won the trophy for Innovation in Sustainability at the Excellence in Building Schools for the Future Awards.

Alistair Brymer, Contracts Manager at Willmott Dixon, main contractor for Hope Academy, commented: "Using McVeigh SIPS gave us excellent insulation values, good continuity of insulation, avoidance of cold bridging and inherent airtightness, which automatically leads to a very thermally efficient building envelope".

From its Stockport head office, McVeigh offers a full service, from design through fabrication to supply and fix.

The company has more than 40 years' experience in creation of insulated structures with low air leakage.
