Acoustic Benefits
Lotus extensive experience with acoustic operable walls has benefited ALL NEW GLAS-STAX. Glas-Stax 6.38 framed and 12mm frameless systems fitted with acoustic perimeter seals offer similar performance and would achieve approx. RW 30 in a laboratory situation.
New Glas-Stax Opera is a specialist double glazed product offering the very best acoustic performance. Based on independent testing on Lotus operable walls, acousticians opinions indicate that laboratory tests of up to RW 42 can be expected for Glas-Stax Opera. In conjunction with opaque film to restrict visual distraction, Glas-Stax can now be effectively used as an acoustic room divider.
