Passive Sills, the Cork-based manufacturer of insulated window sills, has now received an NSAI Agrément certificate for its passive sills system. The company also told Passive House Plus that it was expecting to get its British Board of Agrément certificate imminently, too.

Earlier this summer SEI announced that, from December, external wall insulation systems must have Irish Agrément certification to be eligible for support under the Home Energy Saving scheme. But many in the green building sector are critical of the decision, and some are questioning the value and purpose of Agrément. Lenny Antonelli reports.
