Overview: EPIC Airtightness Guide
EPIC’s guidance document on improved airtightness standards for non-domestic buildings covers the most recent regulations and how these affect airtightness requirements.
Insulated panels have led the way in producing an energy conserving and thermally efficient building fabric. They also meet the primary criteria that buildings should provide long-term energy performance.
Having established the basis for a thermally efficient core fabric for roofs and walls, the Building Regulations to conserve ‘Fuel and Power’ also focus on the airtightness of buildings as a major potential contributor to energy loss.
The document briefly covers the history of air permeability requirements, current regulations, EPIC’s own research into the actual airtightness of buildings, and how to improve compliance with insulated panels.
