The E-Cousti product range and solutions provided in this brochure have been tested to BS EN ISO 140 series and BS EN ISO 717 series to meet the requirements of Approved Document E. Actual acoustic values achieved are a result of rigorous independent laboratory testing to the highest standards. However, variances in performance on site may result, due to workmanship or other external factors that cannot be fully modelled within laboratory conditions.

With this in mind it is important to note there is no product, system, manufacturer or supplier that can offer any guarantee of performance, hence the requirement for Pre-Completion Testing.

Therefore it is advisable to choose a solution that exceeds the acoustic requirement to limit the potential impact of site variances that may occur, or seek advice on your individual situation. All testing shown in this guide was undertaken of either the B.R.E or S.R.L which are both UKAS accredited bodies.
