Sound or acoustic performance of a window is measured by the weighted sound reduction index or Rw value. Rw values are determined by measuring the reduction in dB achieved where a window is used to insulate against a sound source.
The Rw value will increase as the acoustic performance of a window improves, so that a window with an Rw value of 40 has a signi cantly improved acoustic performance over a window with an Rw value of 30. Every improvement in Rw value equates to a reduction in decibels of 1.
The design concept ensures high aesthetics for people who like to have wood windows with less maintenance. The extruded aluminum sections are made from 6060 and 6063 alloy composition with polyamide strip, in order to fulfill system requirements and suitable for high thermal insulation and compatibility for anodizing or painting.
The Wood sections are made from variety of wood species like Teak, Oak and many others, in order to fulfill requirements and coatings.
The system can integrate glazed used from 6mm to 38mm thick glass. Glass blocking must be done through internal/external gaskets in EPDM. The possible infiltration water must be drained outwards, as in the system.
