The America WDMA Association recognizes our tests on windows, doors and skylights

Istituto Giordano, as an ISO / IEC 17025 accredited laboratory by ACCREDIA, has been recognized by the American WDMA Association for tests on doors and windows, doors and skylights according to the main American standards ASTM and AAMA.

After the NAMI and KEYSTONE institutions, this third recognition of the WDMA HALLMARK CERTIFICATION PROGRAM strengthens our work on the American market.

From a practical point of view this means that any European company will be able to perform the performance tests at the Istituto Giordani Italian Laboratories and see them recognized beyond the Ocean.
