Australian Standards Compliance

ThermaDoor insulation, supplied and installed by JaMac Garage Doors, fully meets all relevant Australian standards:

AS/NZS 4859.1:2018 — Ensures material performance and thermal accuracy
AS/NZS 4859.2:2018 — Recognised in NCC 2022 for compliant building design
AS 3999:2015 — Covers safe, professional installation of bulk insulation

Unlike other products that glue insulation directly to door skins—compromising air gaps and breaching safety standards—our partnership with ThermaDoor ensures mechanical fixing methods and spring recalibration that preserve insulation integrity and compliance.
