An Unbiased View of Energy-efficient glazing in SW1X
Underneath the mass-air-mass resonance frequency (about 250 Hz In such a case) the TL of triple glazing is about 3 dB greater, in line with the mass regulation prediction for raising the window’s mass by 50%. At better frequencies, the TL curves are Just about identical. The STC ratings for The 2 windows are the identical.At higher frequencies, t
