DOORS&WINDOWS ‘consistently manufactured’ Like other Q-Mark third party certification schemes, the Acoustic Window and Door Schemes require manufacturers to undertake initial type testing as well as meeting stringent factory production control requirements, to ensure that the product is consistently manufactured to the same specification as that originally tested, with the correct components, absence of air gaps, and with the seals compressed as per the tested sample. BM TRADA undertakes regular factory inspections and audit tests before a manufacturer can be certified. Ironically, despite the noise reducing properties of double glazing being adopted as an early selling point, this additional and increasingly important benefit has more recently been overlooked when manufacturing and selling a window or door. However, the growth in demand for acoustically efficient windows and doors and the ability to simply demonstrate the product’s performance through displaying BM TRADA’s noise reduction rating label looks set to change all that.
