Windows. For Windows, again DO NOT use triple leafed systems. Also, apply the concepts of air tightness, mass, mechanical decoupling, cavity absorption, and differentiation of materials. A simple but effective design for a window is to build a deep frame in the wall (in excess of 4”s) and line the interior with cloth covered 703, do not make the two sides of the wall more mechanically connected than they already are, then install two panes of heavy glass in different thicknesses resting on neoprene bumpers as far apart as the frame will allow (at least 3.5”s), finally caulk around the gap at the edge of the panes with butyl rubber to make the window air tight on both sides. Laminated glass panes are an excellent choice for this sort of system.
Some folks slant one pane of glass – but others think this is a bad idea and recommend that maximum air gap be maintained, follow up by defeating flutter echo off the glass by treating the opposite wall with absorption or diffusion.
