The performance achieved over a lath and plaster ceiling can be variable, as it is dependent on the condition of the ceiling and floorboards to some extent. The joist sizes in the test situation were 75mm x 225mm. The figures quoted here describe what can be achieved from Acoustilay over a floor/ceiling in good condition, but cannot be guaranteed.
Acoustic tests on Acoustilay carried out independently by Noise Control Services at a site in Darwen on 03/11/03. The tests were conducted prior to the changes to the ANC PCT scheme that now requires impact sound insulation tests to be conducted on a rigid board, when a proprietary acoustic underlay has been installed. The tests were conducted in accordance with ISO 140 parts 4 and 7. Rated to ISO 717 parts 1 and 2. Test references: NCS 11031/1, NCS 11031/2. Impact test on Acoustilay, covered with a rigid board, carried out by Floorscan Installations & Surveys Ltd on 20/10/06, in accordance with ISO 140 part 7. Rated to ISO 717 part 2. Test Reference 1260.

Acoustilay 15 can be installed above a double boarded ceiling, fixed on resilient bars, to meet the Building Regulations. The ceiling in this test construction consisted of resilient bars fixed to the joists, with a layer of 15mm Soundbloc plasterboard and a layer of 12.5mm plasterboard fixed to the resilient bars. A rigid board was placed over the Acoustilay prior to the impact test as per the requirements of the ANC's pre-completion testing scheme.
Acoustic tests carried out by Floorscan Acoustic Installation & Surveys Ltd, 14/09/05 in accordance with ISO 140 parts 4 and 7. Rated to ISO 717 parts 1 and 2. Test reference numbers 195- 3, 195-4 (results averaged over two tests).
