Imposed Loads
Altair Louvre Windows have undergone testing to the design loads set out in Clause 3.6 and Table 3.3 AS/NZS 1170.1 “Structural Design Actions” for imposed loads on barrier infills.
In situations where concentrated loads greater than 187N must be withstood Altair Louvres must be specified to include the Stronghold System which mechanically fixes blades into the Altair Stronghold Clips.
