The Altair® Louvre Window System
The Altair Louvre window system has been field tested for sound transmission loss.
The tests were conducted independently by a member firm of the Association of the Australia Acoustical Consultants.
The tests were carried out on Altair windows 2400 high x 840 wide. The windows comprised of a Breezway® Louvre Windows aluminium surround frame complete with 152 Altair louvres. The 2400 high windows consisted of louvres of 16 operable blades with a fixed extension blade.
The results of these field tests gave the following sound transmission loss.
